Opioids and Social Connection. Tristen K. Inagaki. Current Directions in Psychological Science, https://doi.org/10.1177/0963721417735531
Abstract: Social connection, the pleasurable, subjective experience of feeling close to and bonded with other people, is critical for well-being and continued social bonding. Despite the importance of social connection for many important outcomes, few researchers have experimentally examined how humans connect with those to whom they feel close. The strongest insights into the biological bases of social connection come from animal research, which shows that social bonds rely on the same neurochemicals that support general motivation. One class of neurochemicals, opioids, has received increased attention in recent years with the rise of pharmacological methods to manipulate opioids in humans. This article reviews emerging findings to show that opioids affect social feelings, behaviors, and perceptions in both positive and negative social experiences and concludes with the implications of such findings. Future work should consider the subjective feelings of social connection felt during interactions with close social contacts in order to further the understanding of social connection.

A compilation of heat flux recordings from Greenland show the existence of geothermal heat sources beneath GIS and could explain high glacial ice speed areas such as the Northeast Greenland ice stream
High geothermal heat flux in close proximity to the Northeast Greenland Ice Stream. Søren Rysgaard, Jørgen Bendtsen, John Mortensen & Mikael K. Sejr. Scientific Reports 8, Article number: 1344 (2018), doi 10.1038/s41598-018-19244-x
Abstract: The Greenland ice sheet (GIS) is losing mass at an increasing rate due to surface melt and flow acceleration in outlet glaciers. Currently, there is a large disagreement between observed and simulated ice flow, which may arise from inaccurate parameterization of basal motion, subglacial hydrology or geothermal heat sources. Recently it was suggested that there may be a hidden heat source beneath GIS caused by a higher than expected geothermal heat flux (GHF) from the Earth’s interior. Here we present the first direct measurements of GHF from beneath a deep fjord basin in Northeast Greenland. Temperature and salinity time series (2005–2015) in the deep stagnant basin water are used to quantify a GHF of 93 ± 21 mW m−2 which confirm previous indirect estimated values below GIS. A compilation of heat flux recordings from Greenland show the existence of geothermal heat sources beneath GIS and could explain high glacial ice speed areas such as the Northeast Greenland ice stream.

Monastic Tibetan Buddhists showed significantly greater fear of death than any other group. The monastics were also less generous than other groups about the prospect of giving up a slightly longer life in order to extend the life of another

Abstract: It is an old philosophical idea that if the future self is literally different from the current self, one should be less concerned with the death of the future self (Parfit, 1984). This paper examines the relation between attitudes about death and the self among Hindus, Westerners, and three Buddhist populations (Lay Tibetan, Lay Bhutanese, and monastic Tibetans). Compared with other groups, monastic Tibetans gave particularly strong denials of the continuity of self, across several measures. We predicted that the denial of self would be associated with a lower fear of death and greater generosity toward others. To our surprise, we found the opposite. Monastic Tibetan Buddhists showed significantly greater fear of death than any other group. The monastics were also less generous than any other group about the prospect of giving up a slightly longer life in order to extend the life of another.

3.2. Tradeoff
Many in the Buddhist tradition, following classical Indian Buddhist philosophers such as Kamalasıla and Santideva, argue that one of the important consequences of realizing the absence of self and impermanence is the reduction in egocentricity, reflected in the increase in generosity, care, love for others, and the self disappearing as an object of special concern (Garfield, 2015). So, one would expect, if this view is right, that those who see the self as insubstantial and impermanent would be less likely to value their own lives over those of others. Indeed, canonical descriptions of non-egocentricity, generosity, and care are replete with examples of individuals who willingly sacrifice their own good for that of others. The next study explores this with our populations.

3.2.1. Method
Participants were given a task developed from those used to assess the influence of intertemporal self-connectedness on future decision-making (e.g., Bartels & Urminsky, 2011). In this task, participants have to decide the extent to which they would trade off months of their own life for an increasing amount of time for another person. Participants were shown the following instructions:
Participants were given a task developed from those used to assess the influence of intertemporal self-connectedness on future decision-making (e.g., Bartels & Urminsky, 2011). In this task, participants have to decide the extent to which they would trade off months of their own life for an increasing amount of time for another person. Participants were shown the following instructions:
Imagine that you have a terminal disease that will kill you in 6 months unless you take a medication. There is only one dose of the medication available. If you take the medication, it will prolong your life by 6 months. So if you take the medicine, you will live for 12 months instead of 6. If you don’t take the medication, it will go to someone else who has the same condition and will die in 6 months. This person is very much like you but a stranger whom you will never meet or be in contact with.
Participants then indicated whether they would choose to give the medicine to themselves or the stranger if the medicine had varying degrees of efficacy for the stranger. The shortest possible extension of the stranger’s life by the medicine was “1 month or less”; the longest was “more than 5 years,” with eight additional intervals (2 months, 3 months, 6 months, 1 year, etc.) in between. The medicine was always said to prolong the participant’s life by 6 months. Each participant therefore rendered 10 responses (one for each self-other paired decision). Responses were scored by counting the number of times a person opted to give the medicine to themselves; scores ranged from 0 to 10. A score of zero would mean a subject would give up their medicine to the stranger regardless of how long it would prolong their life; a score of 10 would mean a subject would keep the medicine for themselves even if the medicine would prolong the stranger’s life by 5 or more years.

One thousand one hundred and eighty-one participants (701 Americans, 240 Indians, 240 Tibetan monastics; 42.2% female) took the tradeoff task. Of the American participants, 311 identified as Christian and 276 identified as nonreligious. The 41 American participants who indicated other religions were excluded from this analysis, as were 73 Americans who gave incoherent answers (i.e., choosing to keep the medicine that would keep the stranger alive for more time when they had already chosen to give away the medicine when the stranger lived for less time). One Indian subject was excluded for having missing data. We did not collect data from Tibetan or Bhutanese lay Buddhists.

3.2.3. Discussion
There are several ways to interpret this study, some more optimistic than others. One is that Buddhists are more honest about what they would do with medicine if they were sick. While this possibility cannot be ruled out, it would mean that all three comparison groups (Indians, Christian Americans, and nonreligious Americans) are more dishonest than the Tibetans, and we have no good reason to suspect this. Furthermore, the social desirability of answers on the Tradeoff task is far from obvious. Another possibility is that the Tibetan monastics consider their lives more valuable than that of a stranger, because they are more likely to contribute to the world than a person selected at random.
To rule out these possibilities, future studies should measure actual egocentric behavior, see if performance changes when members of the in-group are used (e.g., trading months off your life vs. a Buddhist you have never met), and collect self-report data. Perhaps such work will reveal a principled reason for why the monastic Tibetans gave such egocentric responses.
On the other hand, future work should also explore what the upper bound is for the egocentric responses among the monastics. Because the majority of Tibetan responses were at ceiling for egocentricity, this study may fail to capture just how dramatic these differences are.

3.3. Discussion
Contrary to our central prediction, we did not find that Buddhist monastics showed less fear of self-annihilation than Abrahamics and Hindus. Indeed, to our astonishment, we found that the monastics showed greater fear of self-annihilation than any other group, including lay Tibetans and Western nonbelievers. Furthermore, the Buddhist monastics were less generous with months of their own lives than the Hindus, the Abrahamics, and the Western nonbelievers.
In light of how surprising our results are, it is worth reviewing some of the limitations and alternative explanations of the research. One possibility is that the results on the increased fear of self-annihilation among monastics is a fluke of the sample. We think this is unlikely partly since we sampled from two geographically distinct monasteries, but more importantly because the results on the self-annihilation measure cohered with the results on tradeoff task. In both studies, the monastic Tibetans exhibited significantly higher concern for self-preservation.
Another explanation for our findings might be that the monastic Tibetans did not really believe the no-self view. We think there might be something right about this, but caution is required. Almost all Tibetan monastics in our sample report that they rely on the no-self doctrine as reassurance that death should not be feared. Furthermore, across several measures, we found the monastics to maintain that there is no self. And this is an absolutely central part of their religious tradition. It is as central to Buddhism as the belief that Jesus is the son of God is to Christianity. So, if the monastics were told, “You don’t believe in the no self view,” this would likely inspire strenuous rebuttals. Nonetheless, there might be another sense in which the monastics have not internalized the no-self view deeply enough to deflect fear of death. Indeed, we suspect that something like this is the case, as we will discuss in the final section.
Another limitation of our study is that we focused on a single Buddhist tradition, and it will be important to see whether the findings hold for other traditions as well. Buddhist traditions differ from one another in doctrinal detail, with respect to practice, with respect to relations between lay and monastic communities, and in degree of piety. We have examined only one of these traditions—the Tibetan tradition as it is represented in the Indian exile community and in Bhutan. It will be important in future studies to examine other Buddhist traditions to determine whether the phenomena we have found are general, or whether they are driven in part by properties of the Tibetan community or Buddhist doctrine, per se. If the latter, further study will be required to determine which features of Buddhist doctrine are responsible for these results.

4. Conclusion
Our results suggest a paradoxical effect of Buddhist teaching. Buddhism encourages the belief that there is no persistent self, and this is taken to be a reason not to fear death. We find that monastic Buddhists explicitly deny the existence of a persistent self, in line with Buddhist thought. But contrary to the Buddhist promise of reduced fear of death, the monastic Buddhists showed dramatically increased fear of self-annihilation and valued their own lives over others to a much greater degree.
On every measure we used, the monastics deny the existence of the self. So why do they fail to show the expected reduction in fear of death? We think that it is because, despite their training and explicit claims, they retain a powerful sense of personal identity across the biological lifespan. In particular, like everyone else, Tibetan monastics engage in episodic retrospection and prospection, and this generates a robust sense of personal identity with the past experiencer (see, e.g., Nichols, 2014). Even if you have changed enormously since your first kiss, it will still seem like you had that experience. We propose that even for the monks and nuns, there remains a persistent and powerful sense of identity yielded by episodic memory and prospection within biological life.
The claim that episodic memory generates a sense of personal identity even among monastics is reinforced by looking at work within Tibetan Buddhism. Autobiographies are a primary genre in Tibetan literature. The autobiographies are by people who are held to be of high spiritual attainment (e.g., Gyatso, 1998, 103). It might seem incoherent for an enlightened Buddhist to write an autobiography—how can one affirm an autobiography while denying the self?5 It is certainly clear that these texts make liberal use of the first person singular. The official rejoinder to this alleged incoherence is that these works treat the author as merely a “conventional” person, not an enduring ultimate self. It is possible to speak of persons in this merely conventional fashion, but Tibetan autobiographies suggest that this is not always consistently upheld. Often in these works, the author is reporting a past experience, and the recollections certainly do not seem to present the distanced perspective afforded by thinking that there really is no persisting self.
Rather, they suggest a clear identification with the past experiencer. Consider, for instance, the most famous work in this tradition, The Life of Milarepa. We find the author describing a scene from years earlier in which he had returned to his ancestral home and found human bones among a heap of rags. He writes,

We find the author describing a scene from years earlier in which he had returned to his ancestral home and found human bones among a heap of rags. He writes,
When I realized they were the bones of my mother, I was so overcome with grief that I could hardly stand it. I could not think, I could not speak, and an overwhelming sense of longing and sadness swept over me. (Quintman, 2010, p. 118; see also Shabkar, 1994, p. 32; Kongtrul, 2003; 172–3)
This passage is hardly a dispassionate report that a conventional person consisting of fleeting traits included a set of perceptions. Instead, it seems to be a recollection of a devastating personal experience. It is most plausible that Milarepa, in reflecting on this terrible event, could not suppress the sense that he had the experience of discovering his mother’s bones, even if, in a different register, he would deny that there is any self in which he consists, or that he is now the same person who endured that experience.
The sense of continuity over time within a biological life may be resistant to the ideological conviction that that sense is delusional. Nonetheless, the common view that there is self-persistence between lives may well succumb to the no-self doctrine. If this is the case, it may be that the prospect of death is the prospect of the end of the only kind of self in which one has any conviction. This would be a more dramatic denouement than that anticipated in death by Christians and Hindus, each of whom retains a conviction in the survival of an immortal soul. If monastics do indeed fail to extirpate the sense of continuity, this would help explain both their heightened fear of self-annihilation and their increased egocentricity in tradeoff tasks.
Indeed, this explanation actually fits with a traditional Buddhist distinction between innate self-grasping and philosophical self-grasping. The latter is the conviction in the reality of the self as a result of philosophical or religious doctrine, and it is regarded among Buddhist philosophers as eliminable simply through philosophical reflection. The former, however, is regarded as immune to mere philosophical reflection, and it is argued that only prolonged meditation can dislodge it. None of the participants we studied were long-term meditators (Tsongkhapa, 1991), and one important question for future research will be whether highly experienced practitioners of meditation would in fact show reduced fear of self-annihilation.
The Buddhist may be correct in thinking there is no persisting self and hence that it is irrational to fear death. Nonetheless, as Buddhists themselves recognize, our sense of identity across the biological lifespan is resilient, and perhaps the thought of self-annihilation triggers fears too primitive to be easily tamed by the philosophical belief that there is no persistent self.

The cryptic reaction shot has grown dramatically in movies. The shots are designed to enhance viewers’ emotional involvement with characters. They depict a facial gesture that reflects a slightly negative and slightly aroused emotional state
Cutting, J. E. and Armstrong, K. L. (2018), Cryptic Emotions and the Emergence of a Metatheory of Mind in Popular Filmmaking. Cogn Sci. doi:10.1111/cogs.12586
Abstract: Hollywood movies can be deeply engaging and easy to understand. To succeed in this manner, feature-length movies employ many editing techniques with strong psychological underpinnings. We explore the origins and development of one of these, the reaction shot. This shot typically shows a single, unspeaking character with modest facial expression in response to an event or to the behavior or speech of another character. In a sample of movies from 1940 to 2010, we show that the prevalence of one type of these shots—which we call the cryptic reaction shot—has grown dramatically. These shots are designed to enhance viewers’ emotional involvement with characters. They depict a facial gesture that reflects a slightly negative and slightly aroused emotional state. Their use at the end of conversations, and typically at the end of scenes, helps to leave viewers in a state of speculation about what the character is thinking and what her thoughts may mean for the ongoing narrative.

Is Accurate, Positive, or Inflated Self-perception Most Advantageous for Psychological Adjustment? A Competitive Test of Key Hypotheses
Humberg, Sarah, Michael Dufner, Felix D Schönbrodt, Katharina Geukes, Roos Hutteman, Albrecht Kuefner, Maarten van Zalk, Jaap J A Denissen, Steffen Nestler, and Mitja Back. 2018. “Preprint of "is Accurate, Positive, or Inflated Self-perception Most Advantageous for Psychological Adjustment? A Competitive Test of Key Hypotheses"”. Open Science Framework. January 21. osf.io/9w3bh
Abstract: Empirical research on the (mal-)adaptiveness of favorable self-perceptions, self-enhancement, and self-knowledge has typically applied a classical null-hypothesis testing approach and provided mixed and even contradictory findings. Using data from five studies (laboratory and field, total N = 2,823), we employed an information-theoretic approach combined with Response Surface Analysis to provide the first competitive test of six popular hypotheses: that more favorable self-perceptions are adaptive versus maladaptive (Hypotheses 1 and 2: Positivity of self-view hypotheses), that higher levels of self-enhancement (i.e., a higher discrepancy of self-viewed and objectively assessed ability) are adaptive versus maladaptive (Hypotheses 3 and 4: Self-enhancement hypotheses), that accurate self-perceptions are adaptive (Hypothesis 5: Self-knowledge hypothesis), and that a slight degree of self-enhancement is adaptive (Hypothesis 6: Optimal margin hypothesis). We considered self-perceptions and objective ability measures in two content domains (reasoning ability, vocabulary knowledge) and investigated six indicators of intra- and interpersonal psychological adjustment. Results showed that most adjustment indicators were best predicted by the positivity of self-perceptions, there were some specific self-enhancement effects, and evidence generally spoke against the self-knowledge and optimal margin hypotheses. Our results highlight the need for comprehensive simultaneous tests of competing hypotheses. Implications for the understanding of underlying processes are discussed.

Exploring the Great Schism in the Social Sciences: Confirmation Bias and the Interpretation of Results Relating to Biological Influences on Human Behavior and Psychology
Exploring the Great Schism in the Social Sciences: Confirmation Bias and the Interpretation of Results Relating to Biological Influences on Human Behavior and Psychology. Jeffrey Winking. Evolutionary Psychology, https://doi.org/10.1177/1474704917752691
Abstract: The nature–nurture debate is one that biologists often dismiss as a false dichotomy, as all phenotypic traits are the results of complex processes of gene and environment interactions. However, such dismissiveness belies the ongoing debate that is unmistakable throughout the biological and social sciences concerning the role of biological influences in the development of psychological and behavioral traits in humans. Many have proposed that this debate is due to ideologically driven biases in the interpretation of results. Those favoring biological approaches have been accused of a greater willingness to accept biological explanations so as to rationalize or justify the status quo of inequality. Those rejecting biological approaches have been accused of an unwillingness to accept biological explanations so as to attribute inequalities solely to social and institutional factors, ultimately allowing for the possibility of social equality. While it is important to continue to investigate this topic through further research and debate, another approach is to examine the degree to which the allegations of bias are indeed valid. To accomplish this, a convenience sample of individuals with relevant postgraduate degrees was recruited from Mechanical Turk and social media. Participants were asked to rate the inferential power of different research designs and of mock results that varied in the degree to which they supported different ideologies. Results were suggestive that researchers harbor sincere differences of opinion concerning the inferential value of relevant research. There was no suggestion that ideological confirmation biases drive these differences. However, challenges associated with recruiting a large enough sample of experts as well as identifying believable mock scenarios limit the study’s inferential scope.

Participants were asked to rate the inferential power of different research designs and of mock results that varied in the degree to which they supported different ideologies. Results were suggestive that researchers harbor sincere differences of opinion concerning the inferential value of relevant research. There was no suggestion that ideological confirmation biases drive these differences. However, challenges associated with recruiting a large enough sample of experts as well as identifying believable mock scenarios limit the study’s inferential scope.

Studying Gay and Straight Males' Implicit Gender Attitudes to Understand Previously Found Gender Differences in Implicit In-Group Bias
Studying Gay and Straight Males' Implicit Gender Attitudes to Understand Previously Found Gender Differences in Implicit In-Group Bias. Yvonne Emig, Oyvind Jorgensen. Current Research in Social Psychology 25, 8, 1. http://www.uiowa.edu/crisp
Abstract: Previous research shows that men overall, in contrast to women, do not show a typical implicit in-group preference. One proposed explanation is greater interest in sex among males. If so, then gay males should show an implicit preference for males whereas straight males should prefer females. We tested this hypothesis using a modified version of the Brief Implicit Association Test on 38 gay and 65 straight males. The hypothesis was supported. As the majority of participants in previous studies on implicit gender attitudes are expected to be straight, this could contribute to the low implicit in-group bias among males.
---
Several explanations have been proposed in the literature for the lack of implicit in-group bias among men. One possible explanation for men's intergroup attitudes is maternal bonding, which takes into account that children usually spend more time with the mother and therefore tend to favor their mother over the father (Rudman & Goodwin, 2004). This may be important because many implicit attitudes may be formed through early experiences in the childhood (Rudman, 2004; Skowronski & Lawrence, 2001). Accordingly, Dunham et al. (2015) found that men's gender attitudes change over their lifespan; while 5-year old boys still prefer their own gender, adult men tend to show stronger positive implicit attitudes toward women (Dunham et al., 2015). Perceived threat and stronger association of men with violence are other possible factors, which could explain men's implicit gender associations (Dunham et al., 2015; Rudman & Goodwin, 2004). As men are usually strongly associated with physical threat (such as violence and aggression), men may prefer the less-threatening gender women (Rudman & Goodwin, 2004).
One factor explaining the differences in implicit gender attitudes among men and women could be sexuality. There are gender differences in regard to which stimuli (female or male) cause sexual arousal. While heterosexual women in general tend to be aroused by pictures of men and women, heterosexual men are usually solely aroused by pictures of women (Chivers, Seto, & Blanchard, 2007). Other general differences between men and women seem to be on which behavior they are focused on (e.g. on copulation or a larger scope of activities) and which type of sexual activity arouses them most (Fisher, Aron, Mashek, & Brown, 2002). Sex drive, defined as the strength of motivation for sex, is found to be either more constant (Fisher et al., 2002) or generally stronger (Baumeister, 2000; Baumeister, Catanese, & Vohs, 2001; Peplau, 2003) in men than in women, which could explain why (heterosexual) men do not favor men on implicit associations and why (heterosexual) women do not show pro-male bias. Liking sex was, in Rudman and Goodwin's (2004) study, a predictor of in-group bias among sexually experienced men. However, the sexual explanations (such as liking sex or number of sexual encounters) would not explain a man's lack of in-group bias if this man were gay. So, in the present study, we test whether sexual orientation (gay or straight) is related to implicit gender attitudes among men. In accordance with a sex drive explanation, we expect straight males to show a stronger implicit preference for females than males compared to gay men.

Initial failure made people underestimate how good it would feel to succeed in the future (systematic tendency to downplay the value of inaccessible rewards &outcomes). The predictions of low happiness appear to be a defensive maneuver to prevent disappointment. People high in achievement motivation constituted the main exception.
Sjastad, Hallgeir, Roy Baumeister, and Michael Ent. 2018. “Greener Grass or Sour Grapes? How People Value Future Goals After Initial Failure”. PsyArXiv. January 20. psyarxiv.com/er7q9
Abstract: If initial failure makes future success seem out of reach, do people think that such success would bring them more or less happiness than if initial performance had gone well? Across five experiments (N=690), participants were randomly assigned to receive good or poor feedback on a practice trial of a cognitive test (Studies 1-4) and their academic performance (Study 5). Those who received poor feedback predicted that they would feel less happy about a future top performance than those who received good feedback. However, when all participants received a top score on the actual test they became equally happy, regardless of initial feedback. That is, initial failure made people underestimate how good it would feel to succeed in the future. Inspired by Aesop’s fable of the fox and the grapes, we term this phenomenon the “sour-grape effect”: A systematic tendency to downplay the value of inaccessible rewards and outcomes. A pilot study revealed that people did not anticipate this result even when predicting how others would feel. The predictions of low happiness appear to be a defensive maneuver to prevent disappointment, as indicated by other ratings of whether the trait was relevant to self-concept and one’s future life outcomes. People high in achievement motivation constituted the main exception, as they remained engaged with the task and predicted (correctly) that success would bring them joy. A pre-registered experiment replicated all effects and confirmed mediation and moderation. Findings are interpreted in connection with cognitive dissonance, self-concept defense, adaptive preferences, and affective forecasting.

Lack of Increase in Sexual Drive and Function After Dopaminergic Stimulation in Women – contrary to what happens with men
Lack of Increase in Sexual Drive and Function After Dopaminergic Stimulation in Women. Tillmann H. C. Krüger et al. Journal of Sex & Marital Therapy, Volume 44, 2018 - Issue 1, Pages 61-72 | https://doi.org/10.1080/0092623X.2017.1318797
ABSTRACT: Human and animal data indicate that the dopaminergic system plays a crucial role in sexual drive and function. Using a double-blind, placebo-controlled crossover design, this prototype study investigated the effect of the D2 dopamine agonist cabergoline on sexual parameters in 13 healthy women. Cardiovascular and genital parameters were monitored continuously. Sexual drive and function were measured using self-report sexual experience scales. In contrast to previous theories and assumptions, we found that cabergoline did not alter objective and subjective sexual parameters in healthy women. This finding suggests that there may be sex differences in the influence of the dopaminergic system on human sexual functioning.

Author claims that twelve-month-olds understand that foreign languages can communicate
Voulez-vous jouer avec moi? Twelve-month-olds understand that foreign languages can communicate. Athena Vouloumanos. Cognition, Volume 173, April 2018, Pages 87–92. https://doi.org/10.1016/j.cognition.2018.01.002
Abstract: Infants understand that speech in their native language allows speakers to communicate. Is this understanding limited to their native language or does it extend to non-native languages with which infants have no experience? Twelve-month-old infants saw an actor, the Communicator, repeatedly select one of two objects. When the Communicator could no longer reach the target but a Recipient could, the Communicator vocalized a nonsense phrase either in English (infants’ native language), Spanish (rhythmically different), or Russian (phonotactically different), or hummed (a non-speech vocalization). Across all three languages, native and non-native, but not humming, infants looked longer when the Recipient gave the Communicator the non-target object. Although, by 12 months, infants do not readily map non-native words to objects or discriminate most non-native speech contrasts, they understand that non-native languages can transfer information to others. Understanding language as a tool for communication extends beyond infants’ native language: By 12 months, infants view language as a universal mechanism for transferring and acquiring new information.

Intellectual humility and openness to the opposing view
Intellectual humility and openness to the opposing view. Tenelle Porter & Karina Schumann. Self and Identity, Volume 17, 2018 - Issue 2, https://doi.org/10.1080/15298868.2017.1361861
Abstract: Strong disagreements have stymied today’s political discourse. We investigate intellectual humility – recognizing the limits of one’s knowledge and appreciating others’ intellectual strengths – as one factor that can make disagreements more constructive. In Studies 1 and 2, participants with higher intellectual humility were more open to learning about the opposition’s views during imagined disagreements. In Study 3, those with higher intellectual humility exposed themselves to a greater proportion of opposing political perspectives. In Study 4, making salient a growth mindset of intelligence boosted intellectual humility, and, in turn, openness to opposing views. Results suggest that intellectual humility is associated with openness during disagreement, and that a growth mindset of intelligence may increase intellectual humility. Implications for current political polarization are discussed.

Rare delusional ideation of zoanthropy

In 2010, a 45-year-old geriatric nurse was admitted to a psychiatric hospital for the first time with a severe depressive episode without psychotic symptoms and treated with venlafaxine and amitriptyline. Full remission and part-time work continued for 5 years. By the end of 2015, the patient had discontinued the above-mentioned medication, as she suspected it was a cause of new diarrhea and nausea. In 2016, she was re-hospitalized due to 6 weeks of mood swings with lack of drive and 3 days of confusion.
Findings, therapy and course
Psychopathologically, in this second inpatient psychiatric recording a substantive dementia, paracineses and a rife train of thought. Determined to be a tadpole, the patient made meandering movements with her body, which we interpreted as an expression of this conviction.
Diagnostically, the criteria of an acute schizophreniform disorder were met. The conviction that we are a tadpole was a bizarre delusion, which is a clear symptom of schizophrenia according to ICD-10 (International Statistical Classification of Diseases and Related Health Problems 10). The symptom constellation had occurred only a few hours before the inpatient admission, so that the time criterion of schizophrenia was not met. Physical and apparative investigations gave no indication of an organic genesis. A drug addiction test yielded only negative findings.
Treatment is with 4 mg of risperidone per day. After about a week, the patient stated that she was no longer a tadpole but was still convinced that she had been born a tadpole. Paracines were no longer observable. After about 3 weeks of treatment no delusions was explored more.

Exploring the Relationship Between Narcissism and Extreme Altruism
Exploring the Relationship Between Narcissism and Extreme Altruism. Daniel White, Marianna Szabo and Niko Tiliopoulos. The American Journal of Psychology, Vol. 131, No. 1 (Spring 2018), pp. 65-80. http://www.jstor.org/stable/10.5406/amerjpsyc.131.1.0065
Abstract: Extreme altruism is defined as prosocial behavior that violates social norms or the law. Little research has been done on this phenomenon, although research into related areas suggests that, surprisingly, extreme altruistic activities may be associated with traits traditionally associated with narcissism. This relationship was explored by comparing members of the public, people involved in prosocial activities within socially and legally accepted realms, and members of the Real-Life Superhero (RLSH) movement. The RLSH movement is a subculture whose prosocial-directed activities often exceed social norms and legal constraints. These include patrolling and conducting community and citizen police work in superhero-inspired uniforms, which has on several occasions resulted in altercations with other civilians or with law enforcement. The results suggest that there is a relationship between certain traits within the narcissism spectrum and the proclivity to engage in extreme altruism. These traits include grandiose fantasy, self-sacrificing self-enhancement, and devaluing. Furthermore, these traits are expressed at significantly higher levels in people who engage in extreme altruism more often. Finally, a model based predominantly on narcissism indicated a strong ability to predict group membership among the three groups. The findings suggest that a reconceptualization that reflects the capacity of these traits to be expressed in a prosocial or antisocial behavior is needed to explain this relationship.

Preferences for moral vs. immoral traits (mercifulness vs. mercilessness, honesty vs. dishonesty, sexual fidelity vs. infidelity, and altruism vs. selfishness) in others are conditional
Preferences for moral vs. immoral traits in others are conditional. David E. Melnikoff and April H. Bailey. Proceedings of the National Academy of Sciences, doi 10.1073/pnas.1714945115
Significance: It is commonly argued that humans have a dominant preference for morality traits vs. immorality traits in others—that is, irrespective of the surrounding context, morality fosters liking, and immorality fosters disliking. The results of four experiments oppose this view by showing that situational goals can eliminate and even reverse the preference for morality vs. immorality in others. These findings suggest that our preference for morality vs. immorality is conditional on the demands of our current goals and cannot be attributed solely to innate, “hardwired” links or personal learning experiences. They also suggest that immoral people sometimes win public adoration, and the power that comes with it, not in spite of but precisely because of their immorality.
Abstract: The preference for morality in others is regarded as a dominant factor in person perception. Moral traits are thought to foster liking, and immoral traits are thought to foster disliking, irrespective of the context in which they are embedded. We report the results of four studies that oppose this view. Using both explicit and implicit measures, we found that the preference for morality vs. immorality in others is conditional on the evaluator’s current goals. Specifically, when immorality was conducive to participants’ current goals, the preference for moral vs. immoral traits in others was eliminated or reversed. The preferences for mercifulness vs. mercilessness (experiment 1), honesty vs. dishonesty (experiment 2), sexual fidelity vs. infidelity (experiment 3), and altruism vs. selfishness (experiment 4) were all found to be conditional. These findings oppose the consensus view that people have a dominant preference for moral vs. immoral traits in others. Our findings also speak to nativist and empiricist theories of social preferences and the stability of the “social contract” underlying productive human societies.

Resting autonomic nervous system activity is unrelated to antisocial behaviour dimensions in adolescents: Cross-sectional findings from a European multi-centre study
Resting autonomic nervous system activity is unrelated to antisocial behaviour dimensions in adolescents: Cross-sectional findings from a European multi-centre study. Martin Prätzlich et al. Journal of Criminal Justice, https://doi.org/10.1016/j.jcrimjus.2018.01.004
Highlights
• Respiration rate and antisocial behaviour were positively associated in females.
• Covariates rendered links between the ANS and antisocial behaviour non-significant.
• For both sexes, a low and a high arousal cluster arose.
• Smoking was strongly related to antisocial behaviour and comorbid psychopathology.
Abstract
Purpose: Autonomic nervous system (ANS) functioning has long been studied in relation to antisocial behaviour, but relevant measures (heart rate, heart rate variability, pre-ejection period, respiration rate) have rarely been considered together. This study investigated the relationship between these measures and antisocial behaviour.
Methods: Using a sample of 1010 youths with (47.8%) and without conduct disorder (52.2%) aged between 9 and 18 years (659 females, 351 males, mean age = 14.2 years, SD = 2.4), principal component analysis (PCA) was applied to various measures of psychopathology and antisocial behavior. Structural equation modelling was performed in order to test whether the ANS measures predicted PCA-dimensions. Cluster analysis was used in order to classify patterns of ANS activity. Analyses were performed separately for males/females and controlled for body-mass-index, age, caffeine use, cigarette smoking, sports, socioeconomic status, medication, cardiac problems.
Results: The PCA yielded three components: antisocial behaviour/comorbid psychopathology, narcissistic traits, and callous-unemotional traits. ANS measures were only weakly correlated with these components. Cluster analysis yielded high and low arousal clusters in both sexes. When controlling for covariates, all associations disappeared.
Conclusion: Our findings suggest that resting ANS measures are only weakly related to antisocial behaviour and indicate that smoking should be considered as an important covariate in future psychophysiological studies.

An exploratory study of what people with intellectual disabilities find attractive about romantic partners and how they perceive themselves as romantic partners
Donnachie, Madeline (2017). An exploratory study of what people with intellectual disabilities find attractive about romantic partners and how they perceive themselves as romantic partners. D Clin Psy thesis, University of Glasgow. http://theses.gla.ac.uk/8422/
Abstract
Background: Whilst romantic or sexual attraction is a major research topic in the general population, little is known about people with intellectual disabilities’ views of attractiveness. Research exploring desirable romantic partner traits has indicated that people with intellectual disabilities appeared to hold less conventional views of physical attraction. This research explored what people with intellectual disabilities found attractive in others, as well as whether they thought other people found them desirable.
Method: Twenty-nine adults with intellectual disabilities and twenty-nine adults without intellectual disabilities, all aged between 16 and 40 years old, were recruited from Further Education institutions and voluntary community organisations across Central and West Scotland. Depending on their sexual orientation, participants were shown 50 images of men or women’s faces and asked to rate how attractive they thought the faces were. A semi-structured interview explored participants’ reasons for their highest and lowest ratings, their views of themselves as desirable to others and what they thought were important qualities in a romantic partner.
Results: A strong association was found between what men and women with intellectual disabilities and those without intellectual disabilities considered attractive in romantic partners. With regards to self-perceived desirability as a romantic partner people with intellectual disabilities were more likely to consider themselves desirable or attractive to others compared to their non-disabled peers.
Conclusions: Consideration should be given to how people with intellectual disabilities’ self-perceptions may influence their dating preferences and relationship development. Speaking to people with intellectual disabilities openly about attraction and desirability could provide an opportunity to explore who they view as possible partners and to find ways to help individuals develop relationships. Limitations of the study and ideas for future research are discussed.

With regards to self-perceived desirability as a romantic partner people with intellectual disabilities were more likely to consider themselves desirable or attractive to others compared to their non-disabled peers.
Conclusions: Consideration should be given to how people with intellectual disabilities’ self-perceptions may influence their dating preferences and relationship development. Speaking to people with intellectual disabilities openly about attraction and desirability could provide an opportunity to explore who they view as possible partners and to find ways to help individuals develop relationships. Limitations of the study and ideas for future research are discussed.
The Preference for Pointing With the Hand Is Not Universal
Cooperrider, Kensy, Slotta, James and Nunez, Rafael (2018), The Preference for Pointing With the Hand Is Not Universal. Cognitive Science. doi:10.1111/cogs.12585
Abstract: Pointing is a cornerstone of human communication, but does it take the same form in all cultures? Manual pointing with the index finger appears to be used universally, and it is often assumed to be universally preferred over other forms. Non-manual pointing with the head and face has also been widely attested, but it is usually considered of marginal significance, both empirically and theoretically. Here, we challenge this assumed marginality. Using a novel communication task, we investigated pointing preferences in the Yupno of Papua New Guinea and in U.S. undergraduates. Speakers in both groups pointed at similar rates, but form preferences differed starkly: The Yupno participants used non-manual pointing (nose- and head-pointing) numerically more often than manual pointing, whereas the U.S. participants stuck unwaveringly to index-finger pointing. The findings raise questions about why groups differ in their pointing preferences and, more broadly, about why humans communicate in the ways they do.

Genetics, the Rearing Environment, and the Intergenerational Transmission of Divorce: A Swedish National Adoption Study
Genetics, the Rearing Environment, and the Intergenerational Transmission of Divorce: A Swedish National Adoption Study. Jessica E. Salvatore et al. Psychological Science, https://doi.org/10.1177/0956797617734864
Abstract: We used classical and extended adoption designs in Swedish registries to disentangle genetic and rearing-environment influences on the intergenerational transmission of divorce. In classical adoption analyses, adoptees (n = 19,715) resembled their biological parents, rather than their adoptive parents, in their history of divorce. In extended adoption analyses, offspring (n = 82,698) resembled their not-lived-with fathers and their lived-with mothers. There was stronger resemblance to lived-with mothers, providing indirect evidence of rearing-environment influences on the intergenerational transmission of divorce. The heritability of divorce assessed across generations was 0.13. We attempted to replicate our findings using within-generation data from adoptive and biological siblings (ns = 8,523–53,097). Adoptees resembled their biological, not adoptive, siblings in their history of divorce. Thus, there was consistent evidence that genetic factors contributed to the intergenerational transmission of divorce but weaker evidence for a rearing-environment effect of divorce. Within-generation data from siblings supported these conclusions.

Government-Sponsored Mass Killing and Civil War Reoccurrence
Gary Uzonyi, Richard Hanania; Government-Sponsored Mass Killing and Civil War Reoccurrence, International Studies Quarterly, Volume 61, Issue 3, September 1 2017, Pages 677–689, https://doi.org/10.1093/isq/sqx050
Abstract: Why do civil wars reoccur? Some scholars emphasize the role of post-war factors, while others locate the causes of civil war recurrence in the dynamics of the conflicts themselves. We build a theory that bridges these arguments by focusing on mass killing. We argue that government mass killing during war reduces opportunities for the opposition to return to military conflict in the future. This allows for longer periods of post-conflict peace. However, government atrocities that begin after the end of a civil war create new grievances without diminishing the ability of opponents to fight. This makes a faster return to conflict more likely. Statistical analysis of all civil wars between 1946 and 2006 strongly supports our arguments, even when we account for selection effects regarding when governments are more likely to engage in mass killing. These results reveal that both during-war and post-war tactics influence civil war recurrence, but that the same tactic can produce different effects depending on the timing of its use.

Compassionate Love for a Romantic Partner Across the Adult Life Span: Believers experienced greater compassionate love than nonbelievers, and individuals in love presented greater compassionate love than those who were not in love
Compassionate Love for a Romantic Partner Across the Adult Life Span. Félix Neto, Daniela C. Wilks. European Journal of Psychology, Vol 13, No 4 (2017), https://doi.org/10.5964/ejop.v13i4.1373
Abstract: Compassionate love has received research attention over the last decade, but it is as yet unclear how it is experienced over a lifetime. The purpose of this study was to investigate compassionate love for a romantic partner throughout the adult life span, exploring individual differences in the propensity to experience compassionate love in regard to age, gender, religion, love status, love styles, and subjective well-being. The results showed that religion and love status display significant effects on compassionate love. Believers experienced greater compassionate love than nonbelievers, and individuals in love presented greater compassionate love than those who were not in love. Love styles and subjective well-being were found to be related to compassionate love. These findings corroborate studies that indicate that individuals who experience higher compassionate love for a romantic partner are more likely to report Eros, Agape, and subjective well-being.

Scientific Uncertainty in the Press: How Newspapers Describe Initial Biomedical Findings — the public is increasingly poorly informed about the uncertainty inherent in initial biomedical findings
Scientific Uncertainty in the Press: How Newspapers Describe Initial Biomedical Findings. Estelle Dumas-Mallet et al. Science Communication, https://doi.org/10.1177/1075547017752166
Abstract: Newspapers preferentially cover initial biomedical findings although they are often disconfirmed by subsequent studies. We analyzed 426 newspaper articles covering 40 initial biomedical studies associating a risk factor with 12 pathologies and published between 1988 and 2009. Most articles presented the study as initial but only 21% mentioned that it must be confirmed by replication. Headlines of articles with a replication statement were hyped less often than those without. Replication statements have tended to disappear after 2000, whereas hyped headlines have become more frequent. Thus, the public is increasingly poorly informed about the uncertainty inherent in initial biomedical findings.

Divisive discussion topics are associated with both a greater level of self-reported threat and a greater tendency to perceive neutral faces as threatening
Divisive Topics as Social Threats. Joseph J. P. Simons, Melanie C. Green. Communication Research, http://journals.sagepub.com/doi/abs/10.1177/0093650216644025?journalCode=crxa
Abstract: The current work provides evidence for a psychological obstacle to the resolution of divisive social issues (e.g., affirmative action, drug legalization); specifically, people approach discussions of these issues with a threatened mind-set. Across three studies, it is shown that the prospect of discussing topics which divide social opinion is associated with threatened responding (the dissensus effect). Divisive discussion topics are associated with both a greater level of self-reported threat (Studies 1 and 3) and a greater tendency to perceive neutral faces as threatening (Study 2). Furthermore, the effect is shown to be robust across manipulations of social opinion (ratings of multiple social issues in Studies 1 and 2; fictional polling data in Study 3), and was not reducible to individual attitude extremity (Studies 1 and 3) or a valence effect (Study 2).

Expected Sanctions for Expressing Minority Opinions in Offline and Online Communication
What Do We Fear? Expected Sanctions for Expressing Minority Opinions in Offline and Online Communication. German Neubaum, Nicole C. Krämer. Communication Research, Jan 2018, http://journals.sagepub.com/doi/abs/10.1177/0093650215623837
Abstract: This work proposes the expectation of sanctions as a promising construct to advance spiral of silence research in face-to-face and computer-mediated contexts. We argue that situational factors influence people’s expectations about how their social environment would punish them should they express their viewpoint in a hostile opinion climate. These expected sanctions are suggested to explain the variance in people’s willingness to express a minority opinion across different social situations. An experiment showed that the expectation of being personally attacked can explain why people are more willing to voice a deviant opinion in offline rather than online environments. Findings also revealed that in contemporary social networking websites, wherein users commonly face a personally relevant audience, people are prone to hold back their opinion as they expect losing control over the reactions of their audience. This research extends previous knowledge by presenting a more differentiated theoretical view of the fear of isolation and specifying its role in different situations of public deliberation.

Humans show a significant rightward bias during embracing. Additionally, we showed that this general motor preference is strongly modulated by emotional contexts
Embracing your emotions: affective state impacts lateralisation of human embraces. Julian Packheiser et al. Psychological Research, https://link.springer.com/article/10.1007/s00426-018-0985-8
Abstract: Humans are highly social animals that show a wide variety of verbal and non-verbal behaviours to communicate social intent. One of the most frequently used non-verbal social behaviours is embracing, commonly used as an expression of love and affection. However, it can also occur in a large variety of social situations entailing negative (fear or sadness) or neutral emotionality (formal greetings). Embracing is also experienced from birth onwards in mother–infant interactions and is thus accompanying human social interaction across the whole lifespan. Despite the importance of embraces for human social interactions, their underlying neurophysiology is unknown. Here, we demonstrated in a well-powered sample of more than 2500 adults that humans show a significant rightward bias during embracing. Additionally, we showed that this general motor preference is strongly modulated by emotional contexts: the induction of positive or negative affect shifted the rightward bias significantly to the left, indicating a stronger involvement of right-hemispheric neural networks during emotional embraces. In a second laboratory study, we were able to replicate both of these findings and furthermore demonstrated that the motor preferences during embracing correlate with handedness. Our studies therefore not only show that embracing is controlled by an interaction of motor and affective networks, they also demonstrate that emotional factors seem to activate right-hemispheric systems in valence-invariant ways.

People who went on to develop Parkinson disease tended to have jobs with higher socioeconomic status, those with lower socioeconomic status had a lower PD incidence
Himmelberg, M. M., West, R. J.H., Wade, A. R. and Elliott, C. J.H. (2018), A perceptive plus in Parkinson's disease. Mov Disord.. doi:10.1002/mds.27240
Comment on Beard JD, Steege AL, Ju J, Lu J, Luckhaupt SE, Schubauer-Berigan MK. Mortality from amyotrophic lateral sclerosis and Parkinson’s disease among different occupation groups—United States, 1985–2011. MMWR Morb Mortal Wkly Rep
2017;66(27):718-722.
The puzzle of Parkinson’s disease (PD) is particularly elusive, but the next part of the picture is appearing, and it is a curious one: a tale of men, mice, and flies. Recently, Beard and colleagues1 reported that people who went on to develop PD tended to have jobs with higher socioeconomic status.Their study of > 12 million Americans highlighted more than 110,000 deaths from PD, with excess numbers of workers incommunity services (48%), educational (46%), legal (40%) and the sciences (33%). Such jobs may be demanding of deeper thought, good discrimination, and quick judgments. In a second study of > 4.5 million people from the Swedish census, those with lower socioeconomic status had a lower PD incidence.2
Although this may appear (at first sight) far-fetched, advantages in cognition in people at risk of PD are predicted from our studies of young PD-mimic flies. These have faster, stronger visual responses3,4 when the flies are young; however, in old age they show a loss of response and neurodegeneration. This model is noteworthy because ever since the time of Cajal, the homology of vertebrate and fly visual systems has been recognized, with many similarities at the neural circuit, computational, and developmental levels. Crucially, both flies and vertebrates use dopamine for retinal gain control. Furthermore, it is widely accepted that the extra demand for energy is a major cause of neurodegeneration in PD, so that the loss of visual gain control in young flies will lead to increased visual responses, requiring more Adenosine Triphosphate to pump ions and maintain synaptic transmission.
Increased visual processing, and possibly faster neural signaling, as a result of deficits in retinal dopamine signaling may provide people at risk of PD with advantages in younger life, which impact before the later neurodegeneration. They may be more suited to jobs with higher socioeconomic status, both at interview and in the daily routine. This would explain the new observations.1,2
Furthermore, PD-linked mutations have been around since prehistoric times5 and may therefore have had a selective advantage for young people encountering situations demanding rapid responses, for example, escape or hunting activities.

The personality disorder profile of professional actors
Davison, M., & Furnham, A. (2018). The personality disorder profile of professional actors. Psychology of Popular Media Culture, 7(1), 33-46. http://dx.doi.org/10.1037/ppm0000101
Abstract: The personality disorder trait profiles of 214 professional actors were compared with a general population American sample. Both male and female actors scored significantly higher than nonactors on Antisocial, Narcissism, Histrionic, Borderline, and Obsessive–Compulsive personality disorder scales of the Coolidge Axis-II inventory (Coolidge, 2001). Male actors scored significantly higher than the male comparison group on Schizotypal, Avoidant, and Dependent personality disorder scales. Relationships between personality disorder traits in actors and their self-reported acting abilities, preferences, and success were examined. The results are discussed with reference to how heightened subclinical levels of personality disorders traits are potentially unhelpful to acting performance and managing the demands of the profession. Limitations of the study are noted.

Preferences for discussion partners &groups that are similar to (same party &same opinion) or different from us (different party &different opinion) or that represent a combination: Complete similarity is not always preferred &partisan similarity is preferred over opinion similarity
Political Talk Preferences: Selection of Similar and Different Discussion Partners and Groups. Alyssa C. Morey, Steven B. Kleinman, Mark Boukes. International Journal of Communication, http://ijoc.org/index.php/ijoc/article/view/7381
Abstract: Focusing on two distinct dimensions of similarity and difference (political identity, political opinions), this study uses a within-subjects experimental design implemented in an online survey to examine preferences for discussion partners and groups that are similar to (same party and same opinion) or different from (different party and different opinion) or that represent a combination of similarity and difference (same party and different opinion, or different party and same opinion) relative to oneself. Participants comprising a diverse national sample (N = 820) completed eight political discussion selection tasks (four discussion partner tasks, four discussion group tasks) by ranking four political discussion options from most to least preferred. Results indicate that complete similarity is not always preferred (in analyses of all ranked discussion groups) and that partisan similarity is preferred over opinion similarity (in analyses of first-ranked discussion partners). More generally, findings reveal that preferences for political discussion depend on the context of the discussion, including whether the discussion involves a single discussion partner or a discussion group and whether preference focuses on individuals’ most preferred option only or relative rankings across a range of options.

Feast for the Eyes: Effects of Food Perceptions and Computer Vision Features on Food Photo Popularity
Feast for the Eyes: Effects of Food Perceptions and Computer Vision Features on Food Photo Popularity. Yilang Peng, John B. Jemmott III. International Journal of Communication, http://ijoc.org/index.php/ijoc/article/view/6678
Abstract: The widely circulated food photos online have become an important part of our visual culture. Combining human ratings of food characteristics and computational analysis of visual aesthetics, we examined what contributed to the aesthetic appeal of a diversity of food photographs (N = 300) and likes and comments they received in an artificial newsfeed from participants (N = 399). The results revealed that people tended to like and share images containing tasty foods. Both healthy and unhealthy foods were able to gain likes. Aesthetic appeal and specific visual features, such as the use of arousing colors and different components of visual complexity, also influenced the popularity of food images. This work demonstrates the potential of applying computer vision methods in visual analysis, offers insights into image virality, and provides practical guidelines for communicating healthy eating.

Investigating the Relationship Between Self-Perceived Moral Superiority and Moral Behavior Using Economic Games
Investigating the Relationship Between Self-Perceived Moral Superiority and Moral Behavior Using Economic Games. Ben M. Tappin, Ryan T. McKay. Social Psychological and Personality Science, https://doi.org/10.1177/1948550617750736
Abstract: Most people report that they are superior to the average person on various moral traits. The psychological causes and social consequences of this phenomenon have received considerable empirical attention. The behavioral correlates of self-perceived moral superiority (SPMS), however, remain unknown. We present the results of two preregistered studies (Study 1, N = 827; Study 2, N = 825), in which we indirectly assessed participants’ SPMS and used two incentivized economic games to measure their engagement in moral behavior. Across studies, SPMS was unrelated to trust in others and to trustworthiness, as measured by the trust game, and unrelated to fairness, as measured by the dictator game. This pattern of findings was robust to a range of analyses, and, in both studies, Bayesian analyses indicated moderate support for the null over the alternative hypotheses. We interpret and discuss these findings and highlight interesting avenues for future research on this topic.

Men are presented with higher facial prominence than women in the media (this is called face-ism) -- In lab, as expected, men cropped their photos with higher facial prominence than women did
Self-presentation in Online Professional Networks: Men's Higher and Women's Lower Facial Prominence in Self-created Profile Images. Sabine Sczesny and Michèle C. Kaufmann. Front. Psychol., January 17 2018 | https://doi.org/10.3389/fpsyg.2017.02295
Men are presented with higher facial prominence than women in the media, a phenomenon that is called face-ism. In naturalistic settings, face-ism effects could be driven by gender biases of photographers and/or by gender differences in self-presentation. The present research is the first to investigate whether women and men themselves create this different facial prominence. In a controlled laboratory study, 61 participants prepared a picture of themselves from a half-body photograph, allegedly to be uploaded to their profile for an online professional network. As expected, men cropped their photos with higher facial prominence than women did. However, women and men did not differ in the self-presentational motivations, goals, strategies, and personality variables under investigation, so that the observed face-ism effect could not be explained with these variables. Generally, the higher participants' physical appearance self-esteem, the higher was their self-created facial prominence.
Men are presented with higher facial prominence than women in the media, a phenomenon that is called face-ism. In naturalistic settings, face-ism effects could be driven by gender biases of photographers and/or by gender differences in self-presentation. The present research is the first to investigate whether women and men themselves create this different facial prominence. In a controlled laboratory study, 61 participants prepared a picture of themselves from a half-body photograph, allegedly to be uploaded to their profile for an online professional network. As expected, men cropped their photos with higher facial prominence than women did. However, women and men did not differ in the self-presentational motivations, goals, strategies, and personality variables under investigation, so that the observed face-ism effect could not be explained with these variables. Generally, the higher participants' physical appearance self-esteem, the higher was their self-created facial prominence.
The Elusive Backfire Effect: Mass Attitudes’ Steadfast Factual Adherence
The Elusive Backfire Effect: Mass Attitudes’ Steadfast Factual Adherence. Thomas Wood, Ethan Porter. Political Behavior, https://link.springer.com/article/10.1007/s11109-018-9443-y
Abstract: Can citizens heed factual information, even when such information challenges their partisan and ideological attachments? The “backfire effect,” described by Nyhan and Reifler (Polit Behav 32(2):303–330. https://doi.org/10.1007/s11109-010-9112-2, 2010), says no: rather than simply ignoring factual information, presenting respondents with facts can compound their ignorance. In their study, conservatives presented with factual information about the absence of Weapons of Mass Destruction in Iraq became more convinced that such weapons had been found. The present paper presents results from five experiments in which we enrolled more than 10,100 subjects and tested 52 issues of potential backfire. Across all experiments, we found no corrections capable of triggering backfire, despite testing precisely the kinds of polarized issues where backfire should be expected. Evidence of factual backfire is far more tenuous than prior research suggests. By and large, citizens heed factual information, even when such information challenges their ideological commitments.

Artificial Intelligence And the Challenges of Detecting Rude Conversational Behaviour
On the Challenges of Detecting Rude Conversational Behaviour. Karan Grewal, Khai N. Truong. arXiv.org Computer Science > Human-Computer Interaction, arXiv:1712.09929 [cs.HC], https://arxiv.org/abs/1712.09929
Abstract: In this study, we aim to identify moments of rudeness between two individuals. In particular, we segment all occurrences of rudeness in conversations into three broad, distinct categories and try to identify each. We show how machine learning algorithms can be used to identify rudeness based on acoustic and semantic signals extracted from conversations. Furthermore, we make note of our shortcomings in identifying rudeness in conversations.
Introduction
One-on-one interactions are important in everyday social settings. For instance, in order to attract a potential partner, it is imperative that an individual behave in an appropriate manner. Unfortunately, one-on-one interactions can often result in one party exhibiting rude or inappropriate conversational behaviour. In many cases, the offending party is not aware of the severity of their actions and does not intend to offend the other party. For example, certain individuals may be socially unaware of how others perceive their behaviour. Individuals with learning disabilities, such as autism, may follow this trend. Likewise, young children often lack awareness of their behaviour { a possible explanation for the presence of bullying in elementary schools and why children are generally regarded as immature. In both cases, monitoring a user's conversational behaviour and making them aware of it via active feedback while they are engaged in a one-on-one interaction would be helpful towards correcting their behaviour in such scenarios.
In the last century, there has been a lot of work in the linguistics and psychology domains which attempt to define politeness and acceptable behaviour pertaining to two-person interactions. The most popular of these is Penelope Brown and Steven Levinson's Politeness theory [2]. This theory states that all individuals have two faces: a positive self-image which is the desire to be approved by others, and a negative self-image which is the desire of actions to be unimpeded by others. According to Politeness theory, any external actions which threaten one or more of an individual's faces, such disrespectful gestures, constitute impoliteness. Also, Geoffrey Leech's principle of politeness states that if two individuals are interacting, then there will be some form of disagreement or tension if both individuals are pursuing mutually-incompatible goals -- likening the chance of rude behaviour [8]. Here, goals refers to a psychological state of being. In contrast, Bruce Fraser argues against the theories formulated by Leech, Brown, and Levinson by pointing out that each culture has its own set of social norms which define acceptable behaviour [6]. Therefore, as Fraser argues, the question of whether an individual is behaving in an inappropriate manner is entirely dependent on the context of his/her actions. This view aligns with Robin Lako's notable example of the speaking style in New York [7]. As she states, New Yorkers often use profanity in a casual sense without any intent to offend or be impolite. However, their conversational behaviour is likely to be interpreted as rude in other cultures.
Is there a grounded definition of rudeness with respect to speech which can be derived from classical theories of politeness? In this study, we define define the notion of rude conversational behaviour and explore methods to identify this type of behaviour in two-person interactions. We do this by extracting acoustic and semantic information from an individual's speech and develop methods which attempt to pinpoint exact instances of rude conversational behaviour. Also, we highlight some existing problems which make the task at hand dicult through our findings. Note that we only focus on signals extracted speech data.
