Economic development may not reduce women’s murders by itself, but it can mitigate the effects of male backlash against women who challenge the status quo

Women’s Murders and the Interaction Between Gender (In)equality and Economic Development: A Subnational Analysis in Turkey. Kerim Can Kavakli. Journal of Interpersonal Violence, October 21, 2020. https://doi.org/10.1177/0886260520967164

Abstract: Why are women’s murders (femicide) more common in some localities than in others? This paper addresses this question in the context of Turkey, a country with a high and rising number of women’s murders. It uses province-level data between 2010-2017 and the Negative-Binomial estimator to explore the importance of several socio-economic, cultural, and political factors. It finds that a province’s ethnic composition, divorce rate, gender equality in education, and level of economic development are significant predictors of women’s murders. The main result is that whether economic development reduces femicide depends on other factors: in poorer provinces, there is a strong positive correlation between women’s murders and equality in education and divorce rates, but in richer provinces, these associations are significantly weaker. These results are consistent with the idea that economic development may not reduce women’s murders by itself, but it can mitigate the effects of male backlash against women who challenge the status quo. The main policy implication of this study is that pro-development policies may save more lives if they target those poorer provinces that also carry these additional risk factors.

People are even more outraged by a self-driving car that deliberately kills a less preferred group (e.g., an elderly person over a child) than by one that indiscriminately kills a more preferred group (e.g., a child)

Deliberately prejudiced self-driving vehicles elicit the most outrage. Julian De Freitas, Mina Cikara. Cognition, Volume 208, March 2021, 104555. https://doi.org/10.1016/j.cognition.2020.104555

Abstract: Should self-driving vehicles be prejudiced, e.g., deliberately harm the elderly over young children? When people make such forced-choices on the vehicle's behalf, they exhibit systematic preferences (e.g., favor young children), yet when their options are unconstrained they favor egalitarianism. So, which of these response patterns should guide AV programming and policy? We argue that this debate is missing the public reaction most likely to threaten the industry's life-saving potential: moral outrage. We find that people are more outraged by AVs that kill discriminately than indiscriminately. Crucially, they are even more outraged by an AV that deliberately kills a less preferred group (e.g., an elderly person over a child) than by one that indiscriminately kills a more preferred group (e.g., a child). Thus, at least insofar as the public is concerned, there may be more reason to depict and program AVs as egalitarian.

No strong evidence for any steroid hormonal effects on mate atraction; further, found no compelling robust evidence for mate preference shifts across the ovulatory cycle

Abstract: Are ovulatory cycle shifts in women’s mate attraction and preferences robust? What are underlying mechanisms of potential cycle shifts? These questions are the subject of a current scientific debate surrounding the good genes ovulatory shift hypothesis. Here, we report a large, preregistered, within-subjects study, including salivary hormone measures and conception risk estimates based on luteinizing hormone tests. In four sessions across one ovulatory cycle, N = 257 women (= 1028 sessions) rated the attractiveness of 40 natural male bodies, 40 natural female bodies and 40 objects. Multilevel analyses yielded weak evidence for ovulatory increases in women’s general attraction, specifically to male bodies, though they are not systematically related to changes in steroid hormone levels. Further, we found no compelling robust evidence for mate preference shifts across the cycle, as only one out of many different tests showed some weak evidence for such effects. Mechanisms regulating cycle shifts, the impact of our results on developing and revising cycle shift theories, and influences of different methodologies on results are discussed.

The volume of traffic contracted sharply after COVID-19 lockdowns, but motor vehicle fatality rates, injury accidents, & speeding violations went up, and remained elevated even as traffic began returning toward normal

COVID Lockdowns, Social Distancing, and Fatal Car Crashes: More Deaths on Hobbesian Highways? Marshall W. Meyer . Cambridge Journal of Evidence-Based Policing volume 4, pages238–259, Dec 21 2020. https://link.springer.com/article/10.1007/s41887-020-00059-8


Abstract

Research Question: What happened to US traffic safety during the first US COVID-19 lockdown, and why was the pattern the opposite of that observed in previous sudden declines of traffic volume?

Data: National and local statistics on US traffic volume, traffic fatalities, injury accidents, speeding violations, running of stop signs, and other indicators of vehicular driving behavior, both in 2020 and in previous US economic recessions affecting the volume of road traffic.

Methods: Comparative analysis of the similarities and differences between the data for the COVID-19 lockdown in parts of the USA in March 2020 and similar data for the 2008–2009 global economic crisis, as well as other US cases of major reductions in traffic volume.

Findings: The volume of traffic contracted sharply once a COVID-19 national emergency was declared and most states issued stay-at-home orders, but motor vehicle fatality rates, injury accidents, and speeding violations went up, and remained elevated even as traffic began returning toward normal. This pattern does not fit post-World War II recessions where fatality rates declined with the volume of traffic nor does the 2020 pattern match the pattern during World War II when traffic dropped substantially with little change in motor vehicle fatality rates.

Conclusions: The findings are consistent with a theory of social distancing on highways undermining compliance with social norms, a social cost of COVID which, if not corrected, poses potential long-term increases in non-compliance and dangerous driving.

There are substantial sex differences in brain activity during long-term memory retrieval: There are sex differences (male > female) in the lateral prefrontal cortex, visual processing regions, parahippocampal cortex, & the cerebellum

Are there sex differences in brain activity during long-term memory? A systematic review and fMRI activation likelihood estimation meta-analysis. Dylan S. Spets  &Scott D. Slotnick. Cognitive Neuroscience - Current Debates, Research & Reports, Aug 19 2020. https://doi.org/10.1080/17588928.2020.1806810

Abstract: The degree to which sex differences exist in the brain is a current topic of debate. In the present discussion paper, we reviewed eight functional magnetic resonance imaging (fMRI) papers to determine whether there are sex differences in brain activity during long-term memory retrieval. The objectives were: 1) to compare the experimental parameters in studies reporting significant versus null long-term memory sex differences, and 2) to identify whether specific brain regions were associated with sex differences during long-term memory. The following experimental parameters were extracted from each paper: the number of participants, the average age of participants, stimulus type(s), whether or not performance was matched, whether or not sex differences were reported, the type of between-subject statistical test used, and the contrast(s) employed. The particular experimental parameters employed in each study did not appear to determine whether sex differences were observed, as there were sex differences in all eight studies. An activation likelihood estimation (ALE) meta-analysis was conducted to identify brain regions activated to a greater degree by females than males or males than females. This ALE meta-analysis revealed sex differences (male > female) in the lateral prefrontal cortex, visual processing regions, parahippocampal cortex, and the cerebellum. This constitutes compelling evidence that there are substantial sex differences in brain activity during long-term memory retrieval. More broadly, the present findings question the widespread practice of collapsing across sex in the field of cognitive neuroscience.

Striving to systematize the conditions under which a generalized coalitional psychology gets activated—the recognition of another’s capacity for and likelihood of coordination not only with oneself but with others

Cikara, Mina. 2020. “Causes and Consequences of Coalitional Cognition.” OSF Preprints. December 17. doi:10.31219/osf.io/ktpf7

Abstract: What is a group? How do we know to which groups we belong? How do we assign others to groups? A great deal of theorizing across the social sciences has conceptualized ‘groups’ as synonymous with ‘categories,’ however there are a number of limitations to this approach: particularly for making predictions about novel intergroup contexts or about how intergroup dynamics will change over time. Here I join a growing chorus of researchers striving to systematize the conditions under which a generalized coalitional psychology gets activated—the recognition of another’s capacity for and likelihood of coordination not only with oneself but with others. First I review some recent developments in the cognitive processes that give rise to the inference of coalitions and group-biased preferences (even in the absence of category labels). Then I review downstream consequences of inferences about capacity and likelihood of coordination for valuation, emotions, attribution, and inter-coalitional harm. Finally I review examples of how we can use these psychological levers to attenuate intergroup hostility.


Evolutionary advantage view of symmetry preference: Symmetry is expected be higher for potential partners (here human faces) and higher post-puberty when partner choice becomes more relevant

Preferring and Detecting Face Symmetry: Comparing Children and Adults Judging Human and Monkey Faces. Anthony C. Little and Jack A. F. Griffey. Symmetry 2020, 12(12), 2112; December 19 2020. https://doi.org/10.3390/sym12122112

Abstract

Background: Visual symmetry is often found attractive. Symmetry may be preferred either due to a bias in the visual system or due to evolutionary selection pressures related to partner preference. Simple perceptual bias views predict that symmetry preferences should be similar across types of stimuli and unlikely to be related to factors such as age.

Methods: The current study examined preferences for symmetry across age groups (pre-puberty vs post-puberty) and stimuli type (human face vs monkey face). Pairs of images manipulated for symmetry were presented and participants asked to choose the image they preferred. Participants repeated the task and were asked to detect symmetry.

Results: Both age of observer and stimuli type were associated with symmetry preferences. Older observers had higher preferences for symmetry but preferred it most in human vs monkey stimuli. Across both age groups, symmetry preferences and detection abilities were weakly related. 

Conclusions: The study supports some ideas from an evolutionary advantage view of symmetry preference, whereby symmetry is expected be higher for potential partners (here human faces) and higher post-puberty when partner choice becomes more relevant. Such potentially motivational based preferences challenge perceptual bias explanations as a sole explanation for symmetry preferences but may occur alongside them.

4. Discussion

This study demonstrated that symmetry preference and detection varied according to the type of stimuli being judged and between the children and adult age groups. Preference and detection of symmetry was highest for the adult group, with preference for symmetry higher for human than monkey faces in adults. In the adult group, detection was higher for female faces of both species than male faces, while the pattern was mixed for children. The correlations between preferences for symmetry and its detection were generally positive but low (highest r = 0.25). The dissociation between preference and detection can be seen in adults judging female monkey faces, for which detection of symmetry was highest of all stimuli but preference for symmetry was lowest. The dissociation can also be seen in the children group where detection of symmetry was highest for monkey male faces, but preference was lowest.
Significant preferences for symmetry in human face stimuli for adult observers is consistent with previous work using manipulated stimuli [8,9,21,49]. The finding that symmetry preferences in adults were stronger for human than for monkey faces is also consistent with a previous study showing that symmetry was preferred more in human faces than in monkey faces and abstract art images [39]. Other studies have shown that symmetry is preferred more in salient biological images than in more abstract visual stimuli [36,50], and the results here suggest species can impact preference within the broad category of biological stimuli. Preferences across stimuli were intercorrelated for adults, but the correlations were generally low (the highest for human male and female faces was r = 0.35). This is consistent with previous work showing limited correlations between symmetry preferences for human faces and more abstract stimuli [36]. Taken together, the results here do not generally a support a simple perceptual bias view of symmetry preference that posits preference is a basic process of the perceptual system [22,23,24]. Such a view would predict that symmetry preferences would be similar across stimuli types that vary in symmetry in the same way and that preferences for symmetry across stimuli would be similar within each observer (i.e., if each observers’ preference for symmetry was generated via a basic process, we would expect that process to apply in a similar way across stimuli).
Children did not show significant preferences for symmetry in this study. From a simple perceptual bias view this is surprising as the basic processes of perception should be the same between children and adults. Experience could play a role in the difference as adults have been exposed to more faces than children; however, it seems likely that they will have been exposed to very large number faces by age 8 and this would be likely enough to generate a symmetric internal prototype if that explained preferences for symmetry [21,27,28,29,30]. Preferences for face symmetry is seen when controlling for rated distinctiveness [8], again suggesting that attraction to symmetry is at least partially independent of an individual’s representation of the prototypical face. Given there were also no linear effect between detection and age within the adult sample, greater experience appears an unlikely reason for the difference. Motivation is an alternative explanation, with adult men being more interested in symmetry associated with some aspect of mate quality than male children. While this would be consistent with an evolutionary advantage view for human female faces, it is difficult to apply to preferences for male and monkey faces, which are not relevant for heterosexual male mate preferences. Neither experience or mating motivation appear to explain the pattern of difference between preferences for symmetry in adults and children. Future work can usefully test changes across puberty or across time in younger children to examine mating motivation and experience effects on symmetry preferences.
There was significant detection of symmetry across stimuli for both adults and children, with higher accuracy in the adults. The pattern of detection did not follow the pattern for preference for either adults or children. In adults, preferences were highest for human faces but for detection preferences were highest for female faces, irrespective of species. In children, detection was highest for monkey male faces while preference was lowest for this stimulus type. It is unclear why detection ability varied across both species and sex in both adults and children. That children were better at detecting symmetry in monkey male than human male faces is surprising and suggestive that experience with a stimuli type does not underpin symmetry detection as, if experience were important, we would expect detection to be higher for stimuli with which observers have more experience. The same transforms were applied to human and monkey faces, keeping variation in asymmetry similar. Differences in judging these stimuli are then not dependent on asymmetry present and reflect some other aspect of processing by the observer. Future work can further examine how detection ability varies both with age and different types of stimuli.
Children had lower preferences and lower accuracy in detection of symmetry than adults, and it is possible poor detection explains the lack of preference in children. Controlling for detection, however, a significant difference in preference between adults and children was still seen. This indicates that differences in preference between children and adults is not completely dependent on detection ability. Further, weak correlations between preference and detection also support the idea that this ability does not underpin symmetry preferences. Similarly, the pattern of means for detection and preference noted above suggest the two measures can be decoupled. Overall, results here support previous findings [49] suggesting a dissociation between symmetry preference and detection, but contrast with other studies suggesting preferences can be explained by detection ability [10]. More research is needed to examine the circumstances under which detection and preference are more or less related. For example, it is possible greater deviations in symmetry may lead to a stronger relationship between preference and detection and that, with small deviations, different processes for the two judgments lead to different generated responses.
Overall, the results of this study reveal a complex pattern of preferences across type of stimuli and age group. These preferences appear decoupled from detection ability. The results from adults partially support predictions of an evolutionary advantage view because preferences were higher for human faces than monkey, and marginally higher for human female faces than male faces. This is consistent with ideas that symmetry may be used as a guide to mate quality, e.g., [21,31,32] or general partnerships (including male–male friendship). Higher preferences for symmetry in adults, for who these partnerships are more relevant, than for children is also consistent with the evolutionary view. Indeed, perceptions of health appear to be important in attraction to symmetric human faces [7,51]. The evolutionary view, however, does not explain why symmetry preferences are also higher in adults for monkey faces than in children. The results do not support the idea that simple perceptual bias views explain all of symmetry preference. Previous studies present findings that are difficult to account for, such as symmetry preferences being higher for opposite-sex compared to same-sex faces [33,34,35], also seen in the adult sample here. These results only suggest that the perceptual bias view may not fully account for symmetry preferences and some of symmetry preference could be due to perceptual bias. Indeed, multiple mechanisms may determine symmetry preference that include basic visual system processes and higher order motivational processes acting together. The motivational processes may drive differences in preferences between stimuli types [21,49].

Of the distinct pathways to hypocrisy, violating a moral value that you have signaled to others that you adhere to, & violating a moral value that you genuinely hold, the first is evaluated more negatively

Jordan, Jillian, and Roseanna Sommers. 2020. “False Signaling and Personal Moral Failings: Two Distinct Pathways to Hypocrisy with Unequal Moral Weight.” PsyArXiv. December 25. doi:10.31234/osf.io/87txd

Rolf Degen's take: https://twitter.com/DegenRolf/status/1342345195933880320

Abstract: Moral engagement is a key feature of human nature: we hold moral values, condemn those who violate those values, and attempt to adhere to them ourselves. Yet moral engagement can make us appear hypocritical if we fail to behave morally. When does moral engagement risk triggering ascriptions of hypocrisy? And when do hypocrites—more so than ordinary wrongdoers—earn particular moral outrage? Across four studies (total n = 1,787), we provide evidence of two distinct pathways to hypocrisy: (1) violating a moral value that you have signaled to others that you adhere to (i.e., engaging in false signaling) and (2) violating a moral value that you genuinely hold (i.e., committing a personal moral failing). Furthermore, we show that these pathways have unequal moral weight, such that false signaling is evaluated more negatively. In Study 1, we confirm that paradigmatic hypocrites activate judgments associated with both pathways. In Studies 2-3, we investigate case studies designed to activate one pathway but not the other. We find evidence that both pathways are sufficient to trigger ascriptions of hypocrisy, but false signalers are more likely to be penalized for their hypocrisy (and thus deemed less moral than non-hypocritical transgressors). Finally, Study 4 demonstrates that a target who violates a stated value, but avoids activating either pathway, is judged as neither hypocritical nor immoral—confirming that at least one pathway is necessary for hypocrisy. Together, these findings suggest that false signaling and personal moral failings constitute two distinct pathways to hypocrisy with unequal moral weight.


Dreams reflect nocturnal cognitive processes: Early-night dreams are more continuous with waking life, and late-night dreams are more emotional and hyperassociative

Dreams reflect nocturnal cognitive processes: Early-night dreams are more continuous with waking life, and late-night dreams are more emotional and hyperassociative. J. E. Malinowski, C. L. Horton. Consciousness and Cognition, Volume 88, February 2021, 103071. https://doi.org/10.1016/j.concog.2020.103071

Rolf Degen's take: https://twitter.com/DegenRolf/status/1342363251238195201

Highlights

• Across-the-night dream content differences were investigated.

• Overt continuity with waking life was greater in the early night.

• Hyperassociativity, metaphoricity, and emotionality were greater in the late night.

• Dream content differences map onto alternating across-the-night cognitive functions of sleep.

Abstract: Contributions of specific sleep stages to cognitive processes are increasingly understood. Non-REM sleep is particularly implicated in episodic memory consolidation, whilst REM sleep preferentially consolidates and regulates emotional information, and gives rise to creativity and insight. Dream content reflects these processes: non-REM dreams are more likely to picture episodic memories, whereas REM dreams are more emotional and bizarre. However, across-the-night differences in the memory sources of dream content, as opposed to sleep stage differences, are less well understood. In the present study, 68 participants were awoken from sleep in the early and late night and recorded their dreams and waking-life activities. Early-night dreams were more clearly relatable to (or continuous with) waking life than late-night dreams. Late-night dreams were more emotional-important, more time orientation varied, and more hyperassociative, than early-night dreams. These dream content differences may underlie the mental content that accompanies sleep processes like memory consolidation, emotion-processing, and creativity.

Sexual murderers who dismembered their victims: Criminal dismemberment occurred more often as part of a sexual deviance, not as a rational behavior aimed at avoiding detection

Body dismemberment in sexual homicide cases: lust murder or rational decision? Julien Chopin & Eric Beauregard. Psychology, Crime & Law, Dec 21 2020. https://doi.org/10.1080/1068316X.2020.1863403

Abstract: This study investigates the role of criminal dismemberment in sexual homicide crime-commission process. Specifically, this research aims to empirically determine whether criminal dismemberment is a rational behavior aimed at avoiding detection or an expression of sexual deviance. The sample used in this study comes from the Sexual Homicide International Database (SHIelD). Bivariate and multivariate analyses are performed to examine the differences between the crime commission process of sexual murderers who dismembered their victims (n = 77) and those who did not (n = 585). Findings indicate that criminal dismemberment occurred more often as part of a sexual deviance. Specifically, this behavior is strongly associated with the intention to kill the victim, necrophilia, mutilation of genitals, and commission of extreme acts committed on/with victims’ bodies. Moreover, findings showed that these offenders are more likely to follow an organized modus operandi. Theoretical and practical implications in terms of criminal investigations are discussed.

Financial constraints decrease the happiness consumers derive from their purchases; this, in turn, leads to a consequential outcome: less favorable consumer reviews

Dias, Rodrigo S., Eesha Sharma, and Gavan Fitzsimons. 2020. “Financial Constraints and Purchase Happiness.” PsyArXiv. December 22. doi:10.31234/osf.io/92zhy

Abstract: Financial constraints change attention, choice, and consumption in important ways. This work examines how financial constraints affect one important outcome at a later stage of the consumer decision-making process: purchase happiness. Eight high-powered studies (N = 7,481) demonstrate that financial constraints decrease the happiness consumers derive from their purchases. This, in turn, leads to a consequential outcome: less favorable consumer reviews. This effect occurs because consumers who feel more (vs. less) financially constrained are more likely to consider opportunity costs when evaluating their purchases. Furthermore, this effect is independent of consumers’ objective constraints (e.g. income) and social class, is not due to a general decrease in life satisfaction or mood, and is robust across several purchase types. Consistent with our proposed mechanism, the effect attenuates when opportunity costs are made salient and when consumers consider purchases for which opportunity costs are naturally less salient (i.e., planned purchases). Moreover, although financial constraints decrease actual purchase happiness, they increase expected purchase happiness, suggesting that financial constraints can have differential effects across decision-making stages. Finally, we meta-analyze our file drawer (17,750 participants; 33 studies) to examine how the effect differs across purchase types and discuss theoretical and practical contributions for consumers and marketers.


Younger adults saw themselves as being as “energetic” but “wiser” than their age peers, while older adults saw themselves as being more “energetic” but less “wise” than their age peers

Young people feel wise and older people feel energetic: comparing age stereotypes and self-evaluations across adulthood. Catherine E. Bowen, Svenja M. Spuling, Anna E. Kornadt & Maja Wiest. European Journal of Ageing volume 17, pages435–444(2020). https://link.springer.com/article/10.1007/s10433-019-00548-4

Abstract: We use questionnaire data from the MIDUS study (N = 6325 and a subsample n = 2120) to examine the extent to which people in their late 20s, late 40s and late 60s think that positive characteristics apply to themselves, their age peers and other age groups. Results based on factor analysis confirmed the existence of age stereotypes, such that one constellation of characteristics (wise, caring, calm, knowledgeable, generative; “wise”) was seen as more descriptive of older adults, while another constellation of characteristics (energetic, healthy, willing to learn; “energetic”) was seen as more descriptive of younger adults. Self-evaluations were, however, highly positive and largely independent of age. As a group, younger adults saw themselves as being as “energetic” but “wiser” than their age peers, while older adults saw themselves as being more “energetic” but less “wise” than their age peers. In sum, the results suggest that self-views are relatively independent of existing age stereotypes but also indicate that the “better-than-average effect” depends on age and whether the considered characteristics represent a relative strength or weakness of one’s own age group. The results also indicate that, at the aggregate level, older adults’ tendency to use stereotypes about their age group’s weaknesses as a frame of reference for making flattering self-evaluations seems to outweigh the effects of stereotype internalization.



Brain structure and clinical profile point to neurodevelopmental factors involved in pedophilic disorder

Brain structure and clinical profile point to neurodevelopmental factors involved in pedophilic disorder.

Rolf Degen's take: https://twitter.com/DegenRolf/status/1342043484623138816

Abstract

Objective: Pedophilic disorder (PD) is characterized by persistent sexual interest in prepubertal children causing distress and increasing the risk for child sexual abuse. Although prior research suggests that PD has neurodevelopmental underpinnings, the evidence remains sparse. To aid the understanding of etiology and treatment development, we quantified neurobiological and clinical correlates of PD.

Method: We compared 55 self‐referred, help‐seeking, non‐forensic male patients with DSM‐5 PD with 57 age‐matched, healthy male controls (HC) on clinical, neuropsychological, and structural brain imaging measures (cortical thickness and surface area, subcortical and white matter volumes). Structural brain measures were related to markers for aberrant neurodevelopment including IQ, and the 2nd to 4th digit ratio (2D:4D).

Results: PD was associated with psychiatric disorder comorbidity and ADHD and autism spectrum disorder symptoms. PD patients had lower total IQ than HC. PD individuals exhibited cortical surface area abnormalities in regions belonging to the brain’s default mode network and showed abnormal volume of white matter underlying those regions. PD subjects had smaller hippocampi and nuclei accumbens than HC. Findings were not related to history of child‐related sexual offending. IQ correlated negatively with global expression of PD‐related brain features and 2D:4D correlated with surface area in PD.

Conclusions: In the largest single‐center study to date, we delineate psychiatric comorbidity, neurobiological and cognitive correlates of PD. Our morphometric findings, their associations with markers of aberrant neurodevelopment, and psychiatric comorbidities suggest that neurodevelopmental mechanisms are involved in PD. The findings may need consideration in future development of clinical management of PD patients.


Not only Trolls are Trolling the Internet: A study on dark personality traits, online environment, and commentary styles

Not only Trolls are Trolling the Internet: A study on dark personality traits, online environment, and commentary styles. Anna M. Connysdotter Karlsson, Petri J. Kajonius. International Journal of Personality Psychology, Vol 6 (2020), Dec 23 2020. https://doi.org/10.21827/ijpp.6.37214

Rolf Degen's take: https://twitter.com/DegenRolf/status/1341989172018601985

Abstract: On the Internet, many commentary styles take place on various forums, and abuse is not uncommon. We investigated the personality traits related to individuals’ behaviors on Internet forum posting. The Dark Short Tetrad (SD4) were used to predict (N = 212) three types of commentary styles: Trolling (malicious posting), Lurking (reading/not posting) and Posting (reading/posting). The results showed that Trolling co-varied with Sadism (r = .38) and Machiavellianism (r = .28). The results also showed that people high on dark traits are Trolling the Internet. Exploratory mediator analyses further revealed that various aspects of anonymity trivially moderate personality traits and behavior (indirect effects β ≈ .10). The overall take-home message is that personality traits, especially dark traits, play a role in how individuals express themselves online. This provides well-needed insight in abusive behaviors in forums on the internet.

Fatherhood Is Associated with Increased Infidelity In The Current Relationship

Fatherhood Is Associated with Increased Infidelity and Moderates the Link between Relationship Satisfaction and Infidelity. Tim Jonas Lacker, Andreas Walther, Patricia Waldvogel and Ulrike Ehlert. Psych 2020, 2(4), 370-384, December 21 2020. https://doi.org/10.3390/psych2040027

Abstract

Background: Relationship satisfaction has been identified as an important factor in terms of extradyadic sexual involvement. However, in men, fatherhood might be associated with infidelity by leading to changes in relationship satisfaction and the social life of parents. To date, no study has focused on the association of fatherhood and infidelity, nor the influence of fatherhood on the association between relationship satisfaction and infidelity.

Methods: Using a cross-sectional design, 137 fathers and 116 non-fathers were assessed regarding relationship satisfaction, infidelity, and potential confounds.

Results: Significantly more fathers reported having been unfaithful in the current relationship than non-fathers (30.7% vs. 17.2%). Fathers also reported longer relationship duration, higher relationship satisfaction, and lower neuroticism than non-fathers. Furthermore, fatherhood moderated the association between relationship satisfaction and infidelity insofar that only in non-fathers reduced relationship satisfaction was associated with infidelity.

Conclusions: The results suggest that fatherhood increases the risk of engaging in extradyadic sexual activities and moderates the link between relationship satisfaction and infidelity. However, results need to be interpreted with caution due to the cross-sectional study design and the lack of information about the specific time point of the infidelity incident(s).

4. Discussion

The present study examined the relationship between fatherhood and infidelity, as well as the effect of fatherhood on the association between relationship satisfaction and infidelity. Since infidelity is one of the leading causes of relationship termination causing severe psychological distress in many individuals [6]. This issue is highly relevant in order to achieve a better understanding of the determinants leading to infidelity and to foster the prevention of infidelity.
The results showed increased infidelity in fathers as compared to non-fathers. This is surprising at first glance when considering the investment model, which suggests high investment and commitment for the relationship in fathers resulting in higher relationship satisfaction and a reduced risk for infidelity [15,16]. Previous research also indicates no association between the number of children or parenthood and infidelity, although the available studies are either limited to non-married individuals, used the actual number of children as predictors, while none of the studies focused on fatherhood, relationship satisfaction, and infidelity [31,32,33,34]. However, relationship satisfaction of the couple commonly declines as soon as the child is born [26,27,63]. Furthermore, fathers show an increase in depressive symptoms during the first phase after birth and a residual amount of symptomatology over the first seven years of their child’s life [64,65,66]. We argue that during this time, when the child needs a lot of the parental attention and the relationship satisfaction of the couple is challenged, men are at an increased risk for infidelity. This is supported by research showing couples transitioning to parents. For men, the frequency of sex is significantly more relevant than for women and that infrequent sex is associated with sexual and relationship dissatisfaction in men, but not women [67]. Although, it is known that paternity has several negative consequences for the relationship and the sexual life of fathers and mothers, this is more likely in couples with small children, while couples with older children such as eight years or older do not experience the same challenges anymore and regain some of the lost relationship and sexual satisfaction [63]. On the other hand, it has also been suggested that in couples without children, relationship satisfaction is very low, the relationship is terminated more quickly, while parents are more likely to stay together despite difficulties for the sake of the children [68]. However, this in turn might be associated with an increased risk of infidelity in fathers during difficult relationship periods. Unnoticed needs of fathers during the transition to fatherhood may thus lead to reduced relationship satisfaction resulting in an increased risk for infidelity.
In the present study, fathers showed higher relationship satisfaction than non-fathers. This contradicted previous research, which showed reduced relationship satisfaction in couples transitioning to parents or with young children [26,27,69]. However, our findings support a previously identified U-shaped relation between relationship satisfaction and age of the children in fathers with a decreased relationship satisfaction after birth of the first child and an increase after the child’s age of eight years [63,70]. When considering the characteristics of the present sample (e.g., average age of 47.5 years, average duration of intimate relationship 13.6 years, most of the fathers fathering two or more children), it was evident that many fathers were in the later phase of fatherhood, where relationship satisfaction increased again and even surpassed the relationship satisfaction of the childless couples [70]. Taking another perspective, extramarital sexual activities might positively influence relationship satisfaction in fathers. One could hypothesize that the higher relationship satisfaction for fathers, despite higher rates of infidelity, represents a cognitive coping mechanism to diminish cognitive dissonance after engaging in extramarital sexual activities. Moreover, a form of idealization of the family might play an important role here, since several of the included fathers were part of a study specifically focused on fatherhood [24]. A further possible explanation for the incongruent finding is that lower sexual satisfaction within the relationship may be compensated by extradyadic sexual activity [71]. This, in turn, might result in higher relationship satisfaction within the primary relationship due to the fulfillment of the aspired sexual activity. However, this explanation does not take into account feelings of guilt, and further research is therefore needed to clarify whether guilt has an impact on this association.
In addition, the results show a moderating effect of fatherhood on the association between relationship satisfaction and infidelity. In other words, the effect of relationship satisfaction on infidelity depends on if the participant was a father. More specifically, only in non-fathers was lower relationship satisfaction associated with increased infidelity. This effect can be interpreted according to the mate switching hypothesis, which suggests that non-fathers engage less in extradyadic sexual activities as long as the relationship is perceived as satisfying, while more quickly seeking a new partner in the face of relationship dissatisfaction [19]. This strategy is less appealing to fathers, since changing partners would require a great deal of adaptation with regard to the children involved. Therefore, the link between relationship satisfaction and infidelity among fathers seems to dissolve. Many parent couples come to the point to ask themselves whether it is better to stay in an unsatisfying and conflictual relation for the sake of the children or to separate [68]. And because there is no definite answer to this question, many parents decide to stay in the relationship and within this framework to satisfy their needs as good as possible, which in fathers are also often sexual needs and thus contribute to an increased risk of infidelity [67].
Additionally, the results revealed a discrepancy between directly and indirectly reported infidelity, which was particularly apparent among the fathers. According to the indirect questioning, significantly more fathers had engaged in extradyadic sexual activities than non-fathers (36.6% vs. 21.8%). The reported rates of infidelity are in line with the literature. For instance, Allen et al. [72] reported that around a quarter of married men have engaged in infidelity, with this rate rising to almost 50% in dating relationships [73]. The findings are also consistent with a more recent study from Germany, in which heterosexual men reported infidelity rates of 49% [12]. As most of the participants in this study were married, a rate of just over 30% was seen as representative for the investigated population of Swiss men.
Age and length of relation were positively correlated with infidelity. As the majority of the participants had been married or in a relationship for more than one year, with a mean relationship length of 13.6 years, their relationships can be considered as long-term, which has been shown to increases the risk for infidelity [25]. Fathers and non-fathers did not significantly differ with regard to age, and fathers showed significantly longer relationship length (16.5 years vs. 10.2 years). This was likely contributed to the identified group difference with regard to infidelity. From an evolutionary perspective, higher infidelity rates in longer relationships or older age might be interpreted as a form of ensuring the passing on of genes to as many partners as possible and thus increasing evolutionary fitness. Within the evolutionary psychology framework, another interpretation may be provided by the sexual strategies theory [74], according to which men (and women) follow distinct strategies for short- and long-term sexual relationships, which have evolved during an evolutionary process. Both sexes face different adaptive problems, which they try to solve by weighing up costs and benefits adapted to the needs of the respective situation, i.e., short- or long-term sexual mating. For instance, distress promotes more short-term mating strategies. In contrast to the evolutionary perspective, dissatisfaction and neglect are covariates of sexual motivation for infidelity [75], which might become significantly more important in early fatherhood due to the fact that a couple might experience a shift in lifestyle and responsibilities.
Taken together, we explain the observed findings in such a way that fathers show a substantially reduced relationship satisfaction during the early phases of paternity (e.g., first seven years) and, at the same time, show an increased risk of infidelity. However, since most couples do not want to separate because of their children, this difficult time is eventually overcome followed by an increase in relationship quality and satisfaction. In addition, by raising the children as a couple, one is proud and stronger connected with each other, further leading to increased relationship satisfaction in later phases. Therefore, it will be important for future research to concomitantly map the temporal dynamics of the likelihood of infidelity [34,35] and relationship satisfaction [63,70] over the course of transitioning to parents and raising children to adulthood.

4.1. Limitations and Strengths

The current study had several distinct limitations and strengths. First, infidelity was only assessed with the question of engagement in extradyadic sexual activities, without defining the exact boundaries of “sexual activities”; thus, it was left to the participants’ interpretation how sexual activities are defined. Nevertheless, it is reasonable to assume that the subjective perception of the committing partner is crucial in terms of effects on relationship satisfaction and well-being. However, infidelity was also examined in an indirect way, and thus anonymously, which enabled us to control for social desirability. Furthermore, the question about infidelity did not ask whether infidelity occurred before or exactly when after the birth of the child, and also did not ask about the exact number of incidents or the amount of extradyadic sexual partners. Thus, future research needs to address this issue and capture as precise as possible the time of the extradyadic sexual activity. Another shortcoming of the study is the lack of information about the age of the children, although the number of children was assessed and added as a covariate the age of the oldest child is particularly relevant to identify the period of increased relationship strain due to the first newborn and the period when relationship satisfaction starts to increase again.
Despite these limitations, the study also had several strengths. First, to the best of our knowledge, this is the first study to explicitly focus on the topic of fatherhood, infidelity, and relationship satisfaction. Moreover, we investigated a rather large sample of 253 men, and used validated questionnaires and measurements that enables us to control for possible confounding variables. The questionnaires enabled us to specifically target potentially influencing personality traits and aspects of mental health as covariates. The relatively large sample size allowed for the generalization of the results. Finally, the study investigated indirect effects, which can be regarded as strengths, since infidelity is a complex behavior encompassing multiple aspects. Thus, the measurement of indirect effects enables deeper insights into mechanisms and is more appropriate due to the consideration of the complexity of the behavior.

4.2. Implications

This investigation extended the knowledge about infidelity, especially for fathers. Couples confronted with infidelity experience severe distress. The discovery of infidelity is a critical life event and can cause PTSD-like symptoms with increased anxiety or depression [12,44]. Therefore, it is crucial to provide information about this topic within couples’ therapy. In particular, fathers or expectant fathers and their partners should be educated about relationship changes within fatherhood and the distress this might cause, in order to adequately prepare the expectant parents and prevent infidelity.

Are Men Who Buy Sex Different from Men Who Do Not?: Exploring Sex Life Characteristics Based on a Randomized Population Survey in Sweden

Are Men Who Buy Sex Different from Men Who Do Not?: Exploring Sex Life Characteristics Based on a Randomized Population Survey in Sweden. Charlotte Deogan, Elin Jacobsson, Louise Mannheimer & Charlotte Björkenstam. Archives of Sexual Behavior, Dec 22 2020. https://rd.springer.com/article/10.1007/s10508-020-01843-3

Abstract: The buying and selling of sex is a topic of frequent discussion and a relevant public health issue. Studies of sex workers are available, while studies addressing the demand side of sex are scarce, especially based on robust population data. The current study provides national estimates of the prevalence of and factors associated with having paid for sex among men in Sweden. We used a randomized population-based survey on sexual and reproductive health and rights among ages 16–84 years, linked to nationwide registers. The sample consisted of 6048 men. With a logistic regression, we analyzed what sex life factors were associated with ever having paid for or given other types of compensation for sex. A total of 9.5% of male respondents reported ever having paid for sex. An increased probability of having paid for sex was identified in men who were dissatisfied with their sex life (aOR: 1.72; 95% CI: 1.34–2.22), men reporting having had less sex than they would have liked to (aOR: 2.78; 95% CI: 2.12–3.66), men who had ever looked for or met sex partners online (aOR: 5.07; 95% CI: 3.97–6.46), as well as frequent pornography users (aOR: 3.02; 95% CI: 2.28–3.98) Associations remained statistically significant after adjustment for age, income, and educational attainment. Sex life characteristics such as poor sex life satisfaction, high online sex activity, and frequent pornography use are strongly associated with sex purchase. These findings can help guide and support counselling and prevention activities targeting sex buyers.


Discussion

In this study, we took advantage of unique data from the randomized population-based survey SRHR2017, linked with Sweden’s extensive and high-quality nationwide administrative registers, to identify the proportion of men ever having paid or given other types of compensation for sex in Sweden. Our results confirms that the proportion of men reporting ever having paid for sex in our survey (9.5%) is comparable to previous studies and with other Nordic as well as western European countries (Haavio-Mannila & Rotkirch, 2000; Jones et al., 2015; Schei & Stigum, 2010). The age-group with the highest proportion of men having paid for sex was men above the age of 45 years (11%), and men 30–44 years (10%) reported a similar proportion. The lowest proportion was reported among men 16–29 years of age. It is unclear whether this is due to the question, which provides us with a lifetime prevalence that naturally increases with age, or that sex purchase became illegal in Sweden in 1999.

Our results regarding education and income of buyers also confirm previous studies (BRÃ…, 2008; Priebe & Svedin, 2011), that buyers are from different socioeconomic backgrounds and educational level is not associated with having paid for sex. However, having a very low income seem to be associated with having paid for sex, which may indicate underlying vulnerability and deprivation. This contradicts the findings of Priebe and Svedin (2011) and Milrod and Monto (2017) that a higher proportion of buyers had high income. This could potentially be due to differences in the participant characteristics since Priebe and Svedin (2011) was based on an online panel which in Sweden usually tends to hold a larger proportion of males, and individuals that are better educated and have higher incomes than the population in general (Bosnjak et al., 2013).

To our knowledge, no study based on a randomized population based survey has explored the relationship between sex life satisfaction and sex purchase, however it does seem reasonable to assume dissatisfaction drives demand, including having less sex than one would have liked to. In our findings, we see a strong association between having looked for or met sex partners online and sex purchase. Our results confirm previous findings that buyers do use internet and/or mobile apps for sexual activity to a higher extent than non-buyers (Monto & Milrod, 2014; Priebe & Svedin, 2011).

Our results show a strong statistically significant association between frequent pornography use and ever having paid for sex. Swedish research has shown that frequent pornography users also have higher levels of risk taking such as alcohol and drug use as well as higher sexual risk taking such as early sex debut and experiences of selling sex, in comparison with non-frequent pornography users (Mattebo, Tydén, Häggström-Nordin, Nilsson, & Larsson, 2013; Svedin, Akerman, & Priebe, 2010).

In all, sex life dissatisfaction and not having as much sex as one would have preferred, as well as online sexual activity and frequent pornography use are strongly associated with having paid for sex among Swedish men. This tells us that these individuals differ from men not having paid for sex in terms of sex life characteristics. It also gives us an indication that they may differ in terms of other factors related to sex life and sexual risk taking but it remains unclear how. Need for intimacy and social dimensions could also play a role (Birch & Braun-Harvey, 2019; Monto & Milrod, 2014). These insights are of importance in the prevention of disease and promotion of sexual health. The understanding of who pays for sex and why is key to reduce demand of sexual services and is of importance not only for law enforcement but also for public health interventions and support activities targeted toward both people paying for and people receiving money or other compensation for sex.

The strengths of this study include the use of the unique data SRHR2017, enriched with high-quality nationwide register data. In prior research, information on sex life factors such as satisfaction, pornography use and online partners is lacking while in our study the results contribute to the understanding of mechanisms driving demand for sex. Some study limitations needs to be taken into consideration in contextualizing the results. First, while the SRHR2017 is a population based sample, the response rate was 31% (i.e., 14,500 participants). Non-response might have biased our results, because many people resist disclosing information about sensitive topics such as sexual activities and experiences of illegal actions. Hence, our outcome measure is likely to be underreported. The outcome measure was “Have you ever paid or given other compensation for sex?” A total of 9.5% of men reported ever having paid for sex, of which 2.8% (of the 9.5%) reported having paid for sex during the past year. However, the question was unfortunately vaguely formulated, where all options was put together in the same question. Hence, we cannot differ between non-response and a selected “no” response. Only 0.26% of all men reported they had purchased sex within the last 12 months, hence we chose not to use this estimate in our analyses. It is unclear as to what extent this may include online purchases since the question did not define online versus offline. Second, the variable of sex life satisfaction referred to the past year, while the rest of our variables measured lifetime prevalence. This is a limitation that sets back our possibility to identify correlations to recent sex purchase. Thirdly, in our study, we have no information on relationship status, which would have helped us further in the understanding of the results.

Various indicators of moral character (justice sensitivity, moral value, & moral identity) predicted harsher judgments of others’ than own transgressions, specially when people possessed strong "reputation management" motivation

Dong, Mengchen, Tom Kupfer, and Jan-Willem van Prooijen. 2020. “Being Good to Look Good: Moral Character Is Positively Associated with Hypocrisy Among Reputation-seeking Individuals.” PsyArXiv. December 22. doi:10.31234/osf.io/s4c6y

Abstract: Moral character is widely believed to guide a moral and prosocial life, navigating individuals through decisions about right or wrong. People with a strong moral character therefore may not be expected to behave hypocritically, by imposing stringent moral standards on others but not on themselves. But from an evolutionary perspective, moral character partly functions to maintain a positive reputation, prompting a motivation to appear moral. This account does predict a positive association between moral character and hypocrisy, particularly for individuals who are strongly motivated to gain a positive reputation. Three studies (employing vignettes, large-scale multination panel data, and a behavioral experiment) revealed that various indicators of moral character (justice sensitivity, moral value, and moral identity) predicted harsher judgments of others’ than own transgressions. These self-other discrepancies emerged particularly when people possessed strong reputation management motives. The findings highlight how reputational concerns moderate the link between moral character and moral judgment.




Rolf Degen summarizing... Groups are as susceptible to "choice blindness" as individuals, failing to notice that they had been given false feedback about their previous choices, making the case for the planted ones

Pärnamets, Philip, Jorina von Zimmermann, Ramsey Raafat, Gabriel Vogel, Lars Hall, Nick Chater, and Petter Johansson. 2020. “Choice Blindness and Choice-induced Preference Change in Groups.” PsyArXiv. December 22. doi:10.31234/osf.io/zut93

Rolf Degen's take: https://twitter.com/DegenRolf/status/1341427051413327872

Abstract: Contrary to common belief, our preferences do not only shape our decisions but are also shaped by what decisions we make. This effect, known as choice-induced preference change, has been extensively studied in individuals. Here we document choice-induced preference change in groups. We do so by using the choice-blindness paradigm, a method by which participants are given false feedback about their past choices. Participants are given a second round of choices following the choice blindness manipulation´measuring preference change resulting from accepting the manipulation. In Experiment 1 (N=83), we introduce a roommate selection task used in this paper and use it to replicate choice-induced preference change using choice-blindness in individuals. In Experiment 2 (N=160), dyad members made mutual choices in the roommate selection task and then receive either veridical or false feedback about what choice they made. The majority of the false feedback trials were accepted by the dyads as their own choices, thereby demonstrating choice blindness in dyads for the first time. Dyads exhibited choice-induced preference change and were more likely to choose the originally rejected option on trials where they accepted the manipulation compared to control trials. In Experiment 3 (N=80), we show that the preference effect induced by the choice blindness manipulation at the group level does not generalize back to follow up choices made by individual participants when removed from the group. In all studies, response time analyses further support our conclusions. Choice-induced preference change exists for both individuals and groups, but the level at which the choice was made constrains the influence of that choice on later preferences.


Many people take an essentialist stance toward social categories, leading them to infer that being gay is genetically determined & not subject to free choice or moral responsibility, nor mutable & worth attempting to change

Kumar, Victor, Aditi Kodipady, and Liane Young. 2020. “A Psychological Account of the Unique Decline in Anti-gay Attitudes.” PsyArXiv. December 22. doi:10.31234/osf.io/rvp57

Abstract: Anti-gay attitudes have declined in the U.S. The magnitude, speed, and demographic scope of this change have been impressive especially in comparison with prejudice against other marginalized groups. We develop a psychological account of the unique decline in anti-gay bias in the context of background cultural and political conditions. We highlight two key psychological mechanisms: interpersonal connection and social category classification. First, many people have discovered that a close friend or family member or an admired individual is gay, motivating them to identify the harm and discrimination faced by the individual they know, and catalyzing moral consistency reasoning such that they generalize this interpersonal insight to strangers. Second, many people take an essentialist stance toward social categories, including sexual orientation, leading them to infer that being gay is genetically determined and not subject to free choice or moral responsibility, nor mutable and worth attempting to change. We contrast this to the relationship between essentialism and attitudes toward women and people of color, and provide an account of the difference. This psychological account has implications for the future decline of anti-gay attitudes, in the U.S. and other countries, along with the nascent decline of anti-trans attitudes.


From 2019... Two million faces detected from greater than 6 million photos: Much of the emotional variation at different places can be explained by a few factors such as openness

From 2019... Extracting human emotions at different places based on facial expressions and spatial clustering analysis. Yuhao Kang  Qingyuan Jia  Song Gao  Xiaohuan Zeng  Yueyao Wang  Stephan Angsuesser  Yu Liu  Xinyue Ye  Teng Fei. Transactions in GIS, June 18 2019. https://doi.org/10.1111/tgis.12552

Abstract: The emergence of big data enables us to evaluate the various human emotions at places from a statistical perspective by applying affective computing. In this study a novel framework for extracting human emotions from large‐scale georeferenced photos at different places is proposed. After the construction of places based on spatial clustering of user‐generated footprints collected from social media websites, online cognitive services are utilized to extract human emotions from facial expressions using state‐of‐the‐art computer vision techniques. Two happiness metrics are defined for measuring the human emotions at different places. To validate the feasibility of the framework, we take 80 tourist attractions around the world as an example and a happiness ranking list of places is generated based on human emotions calculated over 2 million faces detected from greater than 6 million photos. Different kinds of geographical contexts are taken into consideration to find out the relationship between human emotions and environmental factors. Results show that much of the emotional variation at different places can be explained by a few factors such as openness. The research offers insights into integrating human emotions to enrich the understanding of sense of place in geography and in place‐based GIS.


Reward processing is remarkably robust against brain damage; reward circuitry is also surprisingly robust against neurodegeneration

Nummenmaa, Lauri, and David Sander. 2020. “Reward and Emotion in the Brain.” PsyArXiv. December 22. doi:10.31234/osf.io/jvahk

Abstract: Pleasure and reward are central for motivation, learning, feeling and allostasis. Although reward is without any doubt an affective phenomenon, there is no consensus concerning its relationship with emotion. In this mini-review we discuss this conceptual issue both from the perspective of theories of reward and emotion as well as human systems neuroimaging. We first describe how the reward process can be understood and dissected as intertwined with the emotion process, in particular in light of the appraisal theories, and then discuss how different facets of the reward process can be studied using neuroimaging and neurostimulation techniques. We conclude that future work needs to focus on mapping the similarities and differences across stimuli and processes that lead to pleasures and rewards and propose that an integrative affective sciences approach would provide means for studying the emotional nature of reward.


Liberals show more Openness/Aesthetic Sensitivity, Intellect/Intellectual Curiosity, Compassion, & Withdrawal/Depression, as well as less Orderliness/Organization, Politeness, & Assertiveness

Beyond Openness to Experience and Conscientiousness: Testing links between lower‐level personality traits and American political orientation. Xiaowen Xu  Christopher J. Soto  Jason E. Plaks. Journal of Personality, December 21 2020. https://doi.org/10.1111/jopy.12613

Abstract

Introduction: Research has consistently revealed positive correlations between political liberalism and Openness to Experience, and between conservatism and Conscientiousness. Most of this research has made use of domain‐level models of the Big Five personality traits. Recent work suggests, however, that each Big Five trait domain can be divided into distinct aspects or facets, which offer more nuanced characterizations of each trait.

Methods: Across four studies (Ns ranging from 1,123 to 116,406), the present research examined the degree to which distinct lower‐level traits would be associated with meaningful differences in political orientation. United States residents completed two different hierarchical Big Five personality measures (the Big Five Aspect Scales and the Big Five Inventory‐2), as well as a range of measures of political orientation.

Results: Across both personality measures, liberal political orientation showed distinct positive associations with the lower‐level traits Openness/Aesthetic Sensitivity, Intellect/Intellectual Curiosity, Compassion, and Withdrawal/Depression, as well as distinct negative associations with Orderliness/Organization, Politeness, and Assertiveness.

Discussion: By examining individual differences at a higher level of granularity, these data provide insight into specific motivations that predispose individuals toward different ends of the political spectrum.

Perceiver’s Agreeableness & Extraversion were uniquely associated with liking targets; targets who expressed positive emotions, looked relaxed, were physically attractive, & looked healthy & energetic, were the most liked

Who likes whom? The interaction between perceiver personality and target look. Jan Erik Lönnqvist, Ville-Juhani Ilmarinen, Markku Verkasalo. Journal of Research in Personality, Volume 90, February 2021, 104044. https://doi.org/10.1016/j.jrp.2020.104044

Highlights

• We investigated determinants of liking at zero-acquaintance.

• Perceivers (N = 385) viewed portrait photographs of Targets (N = 146)

• Different perceivers were differently influenced by appearance cues.

• Targets who displayed non-Duchenne (fake) smiles were generally rated less favorably.

• Those high in N or C, but not those low in A, especially disliked fake smiles.

Abstract: We investigated determinants of liking at zero-acquaintance, focusing on individual differences in perceivers’ reactions to appearance cues. Perceivers (N = 385) viewed portrait photographs of Targets (N = 146). Perceiver’s Agreeableness and Extraversion were uniquely associated with liking targets. Targets who expressed positive emotions, looked relaxed, were physically attractive, and looked healthy and energetic, were the most liked. There were substantial individual differences in how Perceivers were influenced by appearance cues. For instance, Perceivers generally rated targets who displayed non-Duchenne (fake) smiles less favorably than targets who did not smile or targets who displayed Duchenne (authentic) smiles. However, non-Duchenne smiles elicited especially negative ratings from Perceivers high in Neuroticism or Conscientiousness, but not from Perceivers low in Agreeableness.
