Norway: Both sexes are more satisfied in long-term relationships than short-term or intermediate ones, with no sex differences among singles; results are inconsistent with both sexual strategies theory & third wave feminism

Intermediate Relationships and a Nuanced, Feministic Evolutionary Psychology - A Quantitative Study of Relationship Status, Sexual Behavior and Emotions. Nina Charlotte Sølsnes. Master thesis, Institutt for psykologi, Norges teknisk-naturvitenskapelige universitet. 2018. https://brage.bibsys.no/xmlui/handle/11250/2571153

Abstract: Many studies in evolutionary psychology (EP) make a major distinction between short-term vs. long-term relationship status. The current study suggests that relationships with low commitment and intermediate duration are frequent. There is reason to assume that; sexual strategies theory predicts that there will be sex differences in satisfaction depending on relationship status, where men in general are more satisfied with opportunities for short-term mating than women are. Possibly women in intermediate relationships are less satisfied due to low commitment from partners. Third wave feminism predicts that women in intermediate relationships will be more or equally satisfied than men, due to possible exploration of sexuality with greater safety than short-term allows. Participants (N=529) answered questions regarding relationship status, satisfaction and excitement, commitment and quality, and expectancies and sexual behavior. Sample were Norwegian students. 10% of the respondents belonged in the intermediate group. The results are inconsistent with both theoretical approaches. Both sexes are more satisfied in long-term relationships than short-term. There are no sex differences among singles, inconsistent with both perspectives. There were no sex differences in the intermediate group. The intermediates had the same levels of satisfaction as the singles, while excitement was similar to those in relationships. The implications of the findings in relation to both evolutionary psychology and third wave feminism, as well as implications for further research on sexual behavior, are discussed.

In the absence of a clear majority, the diversity of social information produces opposite effects on herding behavior and subjective uncertainty

Navajas, Joaquin, Oriane Armand, Bahador Bahrami, and Ophelia Deroy. 2018. “Diversity of Opinions Promotes Herding in Uncertain Crowds.” PsyArXiv. April 5. doi:10.31234/osf.io/mvy25

Abstract: Classic and recent studies demonstrate how we fall for the ‘tyranny of the majority’ and follow the dominant trend, perhaps wisely, when uncertain. In many social interactions, however, there is no clearly identified majority, and aggregating the various opinions of others is non-trivial. We asked whether in such conditions herding behavior depends on statistical properties of social information, namely, the variance of opinions in a group. Participants privately estimated the price of eight anonymous paintings. Then, in groups of five, they discussed and agreed on a shared estimate for four paintings. Finally, they provided revised individual estimates for all paintings. We observed that groups converged to each other and boosted their confidence. However, the more diverse groups herded more and showed less confidence. These findings suggest that, in the absence of a clear majority, the diversity of social information produces opposite effects on herding behavior and subjective uncertainty.

Insomnia and mortality: a meta-analysis shows that longevity is not impacted

Insomnia and mortality: a meta-analysis. Nicole Lovato, Leon Lack. Sleep Medicine Reviews, https://doi.org/10.1016/j.smrv.2018.10.004

Summary: The purpose of this review was to evaluate the strength of evidence for a relationship between risk of mortality and frequent and ongoing insomnia using a meta-analytic strategy.

Seventeen studies, including a total of 36,938,981 individuals followed up for a mean of 11.6 years, reporting the investigation of the association between mortality and frequent (≥3 nights/week), ongoing (≥1 month) insomnia were identified.

There was no difference in the odds of mortality for those individuals with symptoms of insomnia when compared to those without symptoms (OR= 1.06, 95%CI=0.61-1.84, p=.84). This finding was echoed in the assessment of the rate of mortality in those with and without symptoms of insomnia using the outcomes of multivariate models, with the most complete adjustment for potential confounders, as reported by the individual studies included in this meta-analysis (HR= 1.07, 95%CI=.96-.1.19, p=.22). Additional analyses revealed a tendency for an increased risk of mortality associated with hypnotic use.

The current evidence reinforces the use of cognitive therapy, within a CBTi framework, as a frontline non-pharmacological treatment for insomnia to reassure patients their longevity will not be impacted as a consequence of suffering from insomnia.

Humans & news media prioritize outlying information & one reason for a negativity bias in news consumption & production is that negative information is more “outlying”: that is, further away from expectations

A Model of Attentiveness to Outlying News. P J Lamberson, Stuart Soroka. Journal of Communication, Volume 68, Issue 5, 1 October 2018, Pages 942–964, https://doi.org/10.1093/joc/jqy040

Abstract: This paper offers a formal-theoretical account for the preponderance of negative news content. It draws on work suggesting that humans and news media prioritize outlying information and argues that one reason for a negativity bias in news consumption and production is that negative information is more “outlying”: that is, further away from expectations. Expectations change over time, however, and so too do negativity (and other) biases. This dynamic is explored using some simple simulations, followed by an empirical explication using data on the U.S. economy alongside media coverage of the economy and public economic expectations. The end result is a broadly-generalizable account of the shifting prominence of “outlying” information.

The Salafi Worldview and the Hermeneutical Limits of Mainstream Sunni Critique of Salafi-Jihadism

The Salafi Worldview and the Hermeneutical Limits of Mainstream Sunni Critique of Salafi-Jihadism. Adis Duderija. Studies in Conflict & Terrorism, https://doi.org/10.1080/1057610X.2018.1529359

Abstract: The aim of this article is to point to the hermeneutical limits of the critique of mainstream Sunnism vis-a-vis the Salafi-jihadist interpretations with particular reference to the literature produced by the proponents of the IS. The main argument the article makes is that by subscribing to what will be termed a “Salafi worldview,” mainstream Sunnism shares many interpretationally crucial epistemological and methodological mechanisms with those adopted by the proponents of the ideology behind the IS. As such mainstream Sunnism has strong hermeneutical limits that do not allow it to be in a position to mount an interpretationally effective rebuttal of many beliefs and practices Salafi-jihadists resort to including those pertaining to apostasy, enslavement, and gender-related issues.

---

What matters most from the perspective of the aims of this article is not necessarily the question of whether or not the proponents of the IS interpretations of Islam are citing the Qur’an and hadith de-contextually or selectively,64 or whether or not their appropriation of Hanbali/ahl al-hadith scholars is doing justice to their views or whether or not their appropriation of the Companions or the Salaf are indeed representative but the actual mode of reasoning employed and the epistemological and hermeneutical process that informs their construction of authority and normativity.  Based on the above evidence and analysis it is clearly evident that the mode of reasoning and the construction of authority employed by the IS proponents shares the same Salafi worldview as does mainstream Sunnism. One of the implications of this finding is that theological rebuttals penned by mainstream Sunni scholars have significant hermeneutical limits and make it very difficult to render the interpretations of Salafi-jihadist groups like the IS as hermeneutically unreasonable if mainstream Sunni hermeneutical commitments embodied in the Salafi worldview are taken as normative .  Hence, the persuasive power of mainstream Sunni critique of Salafi-jihadism based on scriptural hermeneutics on issues such as those discussed above, but also others,65 is greatly impaired. Hence, it is not surprising that, for example, in mainstream Sunnism, apostasy is considered to be punishable by death although differences in opinion exist as to what constitutes the acts of apostasy or what its basis is (i.e., religious or political).  66 Or, to provide another example, it is not surprising that there are many shared beliefs, laws, and practices pertaining to the role and status of women in society, including dress codes, between the proponents of mainstream Sunnism and those associated with the IS ideology.67 I argue that these are the result of their shared subscription to the Salafi worldview as described here.

If mainstream Sunnism was to render the views of Salafi-jihadist grounds such as the IS hermeneutically unreasonable it would need to adopt a significantly different approach to conceptualizing the concept of turath by moving away from its emphasis on isnad and a heavily textualist epistemology, and also rethink other aspects of what we described as the Salafi worldview. It would, at the minimum, have to adopt a much more contextualist approach to the conceptualization and interpretation of the Qur’an and the hadith; it would need to rethink the concept of Sunna and its relationship with the methodologies associated with authenticating the hadith and it would need to subscribe to a rationalist Islamic theology and theory of ethics.68

Low levels of professional competency across professional domains can be due to difficulty measuring relevant outcomes, impoverished performance feedback, & lack of accurate assessment tools or decision aids

Assessment of Expert Performance Compared Across Professional Domains. Rick P. Thomas, Ashley Lawrence. Journal of Applied Research in Memory and Cognition, Volume 7, Issue 2, June 2018, Pages 167-176, https://doi.org/10.1016/j.jarmac.2018.03.009

Abstrac: In this paper, we review several task characteristics to explain why experts across domains differ in their level of skill (expertise). Domains may have low levels of professional competency because of difficulty measuring relevant outcomes, impoverished performance feedback, and lack of accurate assessment tools or decision aids. Acknowledging that domains differ furthers research on expertise because it elucidates some common controversies. For example, the role of nurture (job-relevant experience) versus nature (talent or pre-existing abilities) in skilled performance, and the problem that expert-level knowledge and fast decision-making do not always translate into superior performance across domains—the process–performance paradox. Moreover, recommendations for improving domain competence must take into account the underlying differences among domains to provide recommendations appropriate for the current level of competency exhibited by the professionals in the domain.

General Audience Summary: The goal of this paper is to explain why variability in performance exists between professional domains. For example, weather forecasters accurately predict next-day precipitation 82 percent of the time, whereas clinical psychologists and psychiatrists only accurately predict patient violence 39 percent of the time. We review evidence that specific professional domains may have low levels of skill because of difficulty measuring relevant outcomes, impoverished performance feedback, and lack of accurate assessment tools or decision aids. Weather forecasters have access to accurate and usable feedback for their 24-hour precipitation forecasts, whereas clinical psychologists do not have access to feedback of that quality for their predictions of violence. Understanding how differences between professional domains affect performance advances recommendations for improving competence. We also address important issues like why some professionals do not perform better as they gain experience and whether guided practice is really the only ingredient needed to develop high-level skill by evalu-ating the veracity of the claim that it takes 10,000 hours of practice to develop expertise. Similarly, we evaluate whether popular examples, like Shaquille O’Neal’s free-throw shooting improvement under Ed Pablashkis and Judit Polgár’s skill development in chess under her father’s tutelage, are truly mentorship success stories.

Choosing the vocational compared with the academic pathway was associated with higher conscientiousness & less interest in investigative, social, and enterprising activities

School or Work? The Choice May Change Your Personality. Jessika Golle et al. Psychological Science, https://doi.org/10.1177/0956797618806298

Abstract: According to the social-investment principle, entering new environments is associated with new social roles that influence people’s behaviors. In this study, we examined whether young adults’ personality development is differentially related to their choice of either an academic or a vocational pathway (i.e., entering an academic-track school or beginning vocational training). The personality constructs of interest were Big Five personality traits and vocational-interest orientations. We used a longitudinal study design and propensity-score matching to create comparable groups before they entered one of the pathways and then tested the differences between these groups 6 years later. We expected the vocational pathway to reinforce more mature behavior and curtail investigative interest. Results indicated that choosing the vocational compared with the academic pathway was associated with higher conscientiousness and less interest in investigative, social, and enterprising activities.

Gender differences in adult numeracy are larger in societies that combine egalitarianism with gender segregation in the labour market, & smaller in countries with more inequitable gender relations; this is not an outcome of female disempowerment

Gender differences in adult numeracy: a comparative study. Rose Cook. Thesis submitted for the degree of PhD, UCL, June 2018. http://discovery.ucl.ac.uk/10055384/1/Cook_10055384_thesis.pdf

Abstract: This thesis presents a comparative study of gender differences in adult numeracy in 20 OECD countries. It explores the ways in which the widespread male advantage in adult numeracy is associated with gender relations. Gender relations are measured in terms of gender differences in power and status, the gender division of paid and unpaid labour, and gender culture. The thesis uses quantitative secondary analysis of data from the OECD ’s 2012 Programme for International Assessment of Adult Competencies (PIAAC), which provides direct measures of adults’ numeracy skills. The analysis proceeds from an original theoretical framework which combines insights from life course research on the determinants of skills in adulthood, as well as integrating feminist theory of multidimensional gender relations. At the individual level, the results demonstrate that female advances in education do not necessarily equalise adult numeracy. Women’s participation in the labour market is also not enough to guarantee equal levels of adult numeracy: women must also be able to access occupations that use numeracy skills. Cross-nationally, there is no obvious empirical relationship between gender inequality, conventionally conceived, and the gender difference in adult numeracy. Instead, paradoxically, gender differences in adult numeracy are larger in societies that combine egalitarianism with gender segregation in the labour market, and smaller in countries with relatively inequitable gender relations. Overall, there is little evidence that gender differences in adult numeracy are associated with conventional indicators of gender inequality in this sample of countries. The thesis thereby questions the findings of previous research and suggests that instead of being framed as an outcome of female disempowerment, gender differences in adult numeracy should be understood in relation to the multidimensionality of gender relations in post-industrial societies.

Cats were tested in a two-way choice test with human gazing cues; found the hidden food with high success rate by following referential gazes; verbal ostensive cues before gazing made establishing of eye contact with cats faster

Cats (Felis silvestris catus) read human gaze for referential information. Péter Pongrácz, Julianna Szulamit Szapu, Tamás Faragó. Intelligence, https://doi.org/10.1016/j.intell.2018.11.001

Highlights
•    Cats were tested in a two-way choice test with human gazing cues.
•    Cats found the hidden food with high success rate by following referential gazes.
•    Verbal ostensive cues before gazing made establishing of eye contact with cats faster.

Abstract: Companion cats often occupy the same anthropogenic niche as dogs in human families. Still, cat cognition remains an underrepresented research subject in ethology. Our goal was to examine whether two components that are crucial in dog-human communicative interactions (sensitivity to ostensive signals; gaze following) are also present in cats. In a two-object choice task, we used dynamic and momentary gazing in ostensive and non-ostensive communicative situations. We tested 41 cats at their owner's home. Cats on the group level achieved a 70% overall success rate, showing that they are capable of following human gaze as a referential cue. Cats' success rate was unaffected both by the type of gazing and the presence/absence of ostensive communication, showing that the subjects followed readily even the more difficult momentary cues. We found a trend (p = 0.085), showing that young cats (max. 1 year old) may achieve higher success rate than adult animals. Ostension had a significant effect on the latency of eye contact, which was the shortest when the experimenter called the cat's attention with ostensive signals (p = 0.006). Our results are the first that prove cats' ability to follow human gaze, which is considered to be one of the more difficult visual referential signals given during human-animal interactions. Although ostension did not affect the success rate of cats, we found ostensive human signals to be a more effective attention elicitor compared to non-ostensive vocalizations. Our study therefore provided the first insight to the existence of sensitivity to human ostension in another non-human species besides dogs. These results emphasize the possible relevance of the domestication process and responsiveness to socialization in the development of human-compatible socio-cognitive skills even in such animals as the cat, where the ancestor was not a highly social species.

Inside China’s training camps for "soft" boys: “we were too attentive to him and deprived him of the opportunity to be independent. He was not confident and wept at setbacks. He was like a sensitive girl.”

Inside China’s training camps, where boys are learning how to be men. Zhuang Pinghui. South China Morning Post, Nov 04 2018. https://www.scmp.com/news/china/society/article/2171040/inside-chinas-training-camps-where-boys-are-learning-how-be-men


Excerpts:

Wearing headbands reading “Tough Guy” and chanting slogans such as “Who is the best? I am the best”, “Who are we? We are the man”, they were there to learn all about focus, cooperation and competition through lectures, games and American football.

It was the fifth day of an 18-day course held on weekends for boys aged seven to 11 that aims to rescue them from their day-to-day, all-female environment and prevent them from being “oversensitive, vulnerable, whiny, petty or irresponsible”.

Members of the Boys’ Club recite declarations of manhood at the beginning of lectures, which include subjects such as safeguarding their country, honour and dreams.

They make vows to be ambitious and competent as an eagle, smart and kind as a dolphin and persistent and down-to-earth as a horse.

The boys address each other as “comrade” or tongzhi, which literally means to share the same ambition.

Boys’ Club founder Tang Haiyan was a physical education teacher in Beijing before starting his specialised training centre in 2012. Since then, more than 20,000 children have taken part in his courses, including some who travel from far outside Beijing to follow his unique programme.

“There is a crisis in boys’ education and I threw myself into practical actions to save them and help them find their lost masculinity,” Tang said.

This was long before state media became concerned about the softer, more androgynous physical appearance of modern male celebrities and their potential impact on society and young children.

When a nationally televised show for school pupils caused a public outcry in September this year, many parents of boys realised their sons were just not man enough and since then have been spending big bucks on a mission to reverse the trend.

For about 10,000 yuan (US$1,400) parents can sign up their sons for 18 sessions of weekend training. There are other, shorter themed activities such as running topless in winter, climbing a mountain in temperatures of minus 30 degrees Celsius in Heilongjiang, China’s northernmost province, or trekking for a week across a desert.

Last weekend some of the children dressed up as soldiers and played a real-life version of the popular video game Counter-Strike on the set of patriotic military film Wolf Warrior.

Zhang Haiwei, mother of 12-year-old Tong Tong in Qingdao, in the eastern province of Shandong, was determined to send her son for 14 days of military-style training in Beijing after hearing a lecture by Tang five years ago.

“Tong Tong’s father was busy and not around much. I looked after my son and he had been surrounded by women all the time. He was weak and wept whenever there was some difficulty,” Zhang said.

“It might be that we were too attentive to him and deprived him of the opportunity to be independent. He was not confident and wept at setbacks. He was like a sensitive girl.”

[...]

Tang said most boys were raised by their mother and grandmothers, and surrounded by female teachers in school who, in turn, set the same standard for boys as girls – such as to be quiet, behave and not to be naughty all the time.

This, Tang said, was unfair and put boys in a disadvantaged position.

“Boys behave differently from girls and they develop at a different pace, but I have been to many schools, top or average, and it has become a crisis in society that boys are overshadowed by girls,” he said.

“Their confidence has been shattered. We must help boys regain the true colours of men, their masculinity.”

[...]

He felt the boy was being spoiled and would not be able to handle a life like his own in the army, with its long and hard physical exercises.

So two years ago, when he learned Tang was coming to his city, Zhang signed the boy up for two weeks of military style-training that included walking weights across sand, carrying cabers – the Scottish long pole – wrestling, and American football.

“My son Ming Ming came back a changed person,” he said.

“He knew what discipline was and followed rules strictly. He understood the meaning of persistence, team cooperation and competition.”

He signed up for more courses.

They argue that spatial-processing principles in the hippocampal-entorhinal region provide a geometric code to map information domains of cognitive spaces for high-level cognition

Navigating cognition: Spatial codes for human thinking. Jacob L. S. Bellmund, Peter Gärdenfors, Edvard I. Moser, Christian F. Doeller. Science, Vol. 362, Issue 6415, eaat6766, Nov 09 2018. DOI: 10.1126/science.aat6766

A framework for cognitive spaces: Ever since Tolman's proposal of cognitive maps in the 1940s, the question of how spatial representations support flexible behavior has been a contentious topic. Bellmund et al. review and combine concepts from cognitive science and philosophy with findings from neurophysiology of spatial navigation in rodents to propose a framework for cognitive neuroscience. They argue that spatial-processing principles in the hippocampal-entorhinal region provide a geometric code to map information domains of cognitive spaces for high-level cognition and discuss recent evidence for this proposal.

Abstract: The hippocampal formation has long been suggested to underlie both memory formation and spatial navigation. We discuss how neural mechanisms identified in spatial navigation research operate across information domains to support a wide spectrum of cognitive functions. In our framework, place and grid cell population codes provide a representational format to map variable dimensions of cognitive spaces. This highly dynamic mapping system enables rapid reorganization of codes through remapping between orthogonal representations across behavioral contexts, yielding a multitude of stable cognitive spaces at different resolutions and hierarchical levels. Action sequences result in trajectories through cognitive space, which can be simulated via sequential coding in the hippocampus. In this way, the spatial representational format of the hippocampal formation has the capacity to support flexible cognition and behavior.

Structured Abstract

BACKGROUND: Ever since Edward Tolman’s proposal that comprehensive cognitive maps underlie spatial navigation and, more generally, psychological functions, the question of how past experience guides behavior has been contentious. The discovery of place cells in rodents, signaling the animal’s position in space, suggested that such cognitive maps reside in the hippocampus, a core brain region for human memory. Building on the description of place cells, several other functionally defined cell types were discovered in the hippocampal-entorhinal region. Among them are grid cells in the entorhinal cortex, whose characteristic periodic, six-fold symmetric firing patterns are thought to provide a spatial metric. These findings were complemented by insights into key coding principles of the hippocampal-entorhinal region: Spatial representations vary in scale along the hippocampal long axis, place cells remap to map different environments, and sequential hippocampal activity represents nonlocal trajectories through space. In humans, the existence of spatially tuned cells has been demonstrated in presurgical patients, and functional magnetic resonance imaging provides proxy measures for the noninvasive investigation of these processing mechanisms in human cognition. Intriguingly, recent advances indicate that place and grid cells can encode positions along dimensions of experience beyond Euclidean space for navigation, suggesting a more general role of hippocampal-entorhinal processing mechanisms in cognition.

ADVANCES: We combine hippocampal-entorhinal processing mechanisms identified in spatial navigation research with ideas from cognitive science describing a spatial representational format for cognition. Cognitive spaces are spanned by dimensions satisfying geometric constraints such as betweenness and equidistance, enabling the representation of properties and concepts as convex regions of cognitive space. We propose that the continuous population code of place and grid cells in the hippocampal-entorhinal region maps the dimensions of cognitive spaces. In these, each stimulus is located according to its feature values along the relevant dimensions, resulting in nearby positions for similar stimuli and larger distances between dissimilar stimuli. The low-dimensional, rigid firing properties of the entorhinal grid system make it a candidate to provide a metric or distance code for cognitive spaces, whereas hippocampal place cells flexibly represent positions in a given space. This mapping of cognitive spaces is complemented by the additional coding principles outlined above: Along the hippocampal long axis, cognitive spaces are mapped with varying spatial scale, supporting memory and knowledge representations at different levels of granularity. Via hippocampal remapping, spaces spanned by different dimensions can be flexibly mapped and established maps can be reinstated via attractor dynamics. The geometric definition of cognitive spaces allows flexible generalization and inference, and sequential hippocampal activity can simulate trajectories through cognitive spaces for adaptive decision-making and behavior.

OUTLOOK: Cognitive spaces provide a domain-general format for processing in the hippocampal-entorhinal region, in line with its involvement beyond navigation and memory. Spatial navigation serves as a model system to identify key coding principles governing cognitive spaces. An important question concerns the extent to which firing properties of spatially tuned cells are preserved in cognitive spaces. Technological advances such as calcium imaging will clarify coding principles on the population level and facilitate the translation to human cognitive neuroscience. Spatial navigation is mostly investigated in two dimensions and naturally limited to three dimensions; however, the processing of complex, multidimensional concepts is vital to high-level human cognition, and the representation of such high-dimensional spaces is an intriguing question for future research. Further, the role of brain networks acting in concert with the hippocampus, in navigation specifically and cognitive function in general, will provide insight into whether and how cognitive spaces are supported beyond the hippocampal-entorhinal region. Finally, the precise way in which cognitive spaces and trajectories through them are read out for behavior remains to be elucidated.

Found some evidence that both self-reported formidability is associated with higher levels of conservatism in women & self-reported grip strength with conservatism in men

Is Formidability Associated with Political Conservatism? Nicholas Kerry, Damian R. Murray. Evolutionary Psychological Science, https://link.springer.com/article/10.1007/s40806-018-0181-5

Abstract: Physical formidability has played an important role in intra-sexual competition throughout human history, influencing social capital and, in turn, social cognition. However, the degree to which physical formidability is associated with social and political attitudes in contemporary environments remains poorly understood. The current studies tested the hypotheses that formidability is associated with more politically conservative attitudes and, more specifically, less support for financial egalitarianism and more approval of military intervention. Across three studies, comprised of both online and undergraduate samples (two pre-registered; total N > 900), we found some evidence that both self-reported formidability and grip strength were associated with higher levels of conservatism. However, this evidence was inconsistent across different measures and across samples, with relatively small effects for some conservatism measures and no effects for others. There also emerged sex differences, such that self-reported formidability was a better predictor of conservatism in women and objective grip strength was a better predictor of conservatism in men. Unlike previous research, we did not find consistent evidence of a relationship between formidability and either financial egalitarianism or military approval. Attempted experimental manipulations of formidability in studies 2 and 3 yielded inconsistent results.

Does legal marijuana access blunt academic performance in college? It does.

Getting into the weeds: Does legal marijuana access blunt academic performance in college? Adam C. Wright, John M. Krieg. Economic Inquiry, https://doi.org/10.1111/ecin.12743

Abstract: This paper examines the effect of legal access to marijuana on student performance stemming from a voter‐approved initiative legalizing marijuana for those 21 and older in the State of Washington. Using panel data from a medium‐sized public university, we use a within‐student and within‐class estimator to show that legalization reduces students' grades, with an effect size about one‐half the impact of gaining legal access to alcohol. Consistent with how marijuana consumption affects cognitive functioning, we find that students' grades fall furthest in courses that require more quantitative skills. These effects are largely driven by men and low performers. (JEL I23, I18, K32)

How negative parenting might hamper identity development: spontaneous aggressiveness and personal belief in a just world

How negative parenting might hamper identity development: spontaneous aggressiveness and personal belief in a just world. Jan Hofer & Benedikt Spengler. Self and Identity, https://doi.org/10.1080/15298868.2018.1541026

ABSTRACT: Based on studies indicating that identity formation is shaped by perceived negative parenting and personal factors, we hypothesized that negative parenting relates to adolescents’ self-reported spontaneous aggressiveness and their personal belief in a just world and consequently, is associated with problems developing a firm meaningful interpersonal identity. In a series of four studies, we gathered data from 807 German students aged between 13 and 18 years by using two well-validated methods for measuring of identity development (i.e., Extended Objective Measure of Ego Identity Status, Study 1; Utrecht-Management of Identity Commitments Scale, Studies 2/4). Analyses revealed an indirect link of negative parenting on facets of identity development via spontaneous aggressiveness (Studies 1 and 2). Based on findings that negative parenting was associated with spontaneous aggressiveness via personal belief in a just world (Study 3), analyses conducted in Study 4 indicate a two-staged indirect link of negative parenting on facets of identity development through personal belief in a just world and spontaneous aggressiveness. Above all, problems in the development of and satisfaction with personal meaningful identity commitments could be verified. Implications for research on interpersonal identity formation are discussed.

Self-control has largely been thought to exclusively promote socially-desirable behaviors; but consistent with newer models, it is equally plausible that, under some circumstances, could increase obedient aggression

The Intricacies of the Pursuit of Higher Self-Control. Liad Uziel. Current Directions in Psychological Science, https://doi.org/10.1177/0963721417744322

Abstract: Self-control is a central human capacity associated with a wide range of personal and societal advantages. In view of its benefits, increasing self-control among children and adults has been advocated as a remedy to many of society’s illnesses. This approach is evident in the popular media, as well as in educating and governing agencies, and has subsequently taken root in the general public. The present article advocates a broader approach by noting some of the downsides of the pursuit of high self-control. It does so by highlighting often-ignored issues relating to (a) uncertainties about the nature of self-control, (b) nuances concerning the benefits of high self-control, and (c) undesirable implications of wanting more self-control. The conclusion is that research on self-control should deal not only with the benefits of self-control but also with the costs associated with advocating, wanting, and even having high self-control. This approach would provide society with informed knowledge about potential side effects of one of the most powerful psychological solutions to its ailments.

Check also “Thou Shalt Kill”: Practicing self-control supports adherence to personal values when asked to aggress. Thomas F. Denson et al. Journal of Experimental Social Psychology (2016), http://dx.doi.org/10.1016/j.jesp.2016.09.001

Abstract: Poor self-control is a root cause of aggression and criminality. But people can improve their self-control through repetitive practice. Because self-control involves acting in accordance with personal values, practicing self-control can promote attainment of value-consistent goals. The present research tested the hypothesis that practicing self-control could both decrease and increase obedient aggression. In Experiment 1, relative to the active control group, participants who practiced self-control were more hesitant to engage in mock violence (e.g., “cutting” the experimenter's throat with a rubber knife), especially for participants high in dispositional empathy. In Experiment 2, practicing self-control increased obedience to kill insects, but only among participants who felt little moral responsibility for their actions. There was a trend for decreased killing among participants who feltmorally responsible for their actions. Our findings suggest thatwhen asked to behave aggressively, self-control promotes adherence to personal values, which may or may not fuel aggression.

To date, self-control has largely been thought to exclusively promote socially-desirable behaviors. For instance, studies showing that self-control reduces reactive aggression strongly support this notion (Denson et al., 2011; Finkel et al., 2009; Moffitt et al., 2011). However, consistent with newer models of self-control (Fujita, 2011; Inzlicht, Schmeichel et al., 2014), it is equally plausible that under some circumstances, SCT could increase obedient aggression
