Objectives: Sleep deprivation (SD) has detrimental effects on cognition. Emotional processing, a critical component of social cognition, is also affected by SD. However, current research on how SD affects emotion recognition and the specific emotion recognition that declines with SD is inconsistent. The present study meta-analyzed results of studies examining emotion category recognition changes in SD compared with controls.

Methods: PubMed, Web of Science, Embase, PsychINFO, MEDLINE, and China National Knowledge Infrastructure databases were searched. Studies on the impact of acute SD or insomnia on emotional recognition and participants aged 18 years or older were included in this review. The JBI Critical Appraisal Checklist and GRADE approach were used to assess the quality of the studies and evidence.

Results: Twelve studies with 414 SD and 399 control participants were included in this meta-analysis. The SD group performed poorer on facial sadness (MD = -4.35; 95% CI, -7.99 to -0.71) and happiness (MD = -1.75; 95% CI, -3.25 to -0.26) recognition than the control group (normal sleep condition). The reaction time of the SD group was significantly longer than that of the control group for all emotional categories. The intensity rating of facial emotions showed no difference between the two groups.

Conclusions: Sleep deprivation slows individuals' reactions in facial emotion recognition tasks and weakens their ability to recognize sadness and happiness. Future studies should identify the effects of SD, SD duration, and recovery time on different types of emotion recognition.

Although explicit measures of doping attitude are widely used, they are susceptible to bias due to social desirability. The current computerized measures of implicit attitudes are time-consuming and based on expensive software solutions. Recently, paper-and-pencil (p&p) Implicit Association Tests (IAT) have been developed, making it possible to test several participants simultaneously, anywhere, and with no need of computerized equipment and software. The present series of studies aimed at developing a French version of a p&p IAT to measure athletes' attitudes toward doping (Chan et al., 2017): the IAT-Dop. Four studies, including 212 participants (Mage = 25.49, SD = 5.73), followed Bardin et al. (2016) and Boateng et al. (2018) validation recommendations: (a) development of a preliminary version of the IAT-Dop based on the proposal of Chan's tool (2017), (b) dimensionality and criterion validity tests demonstrating the structure of the p&p version, (c) test-retest reliability, and (d) first approach to construct validity. The results showed that the IAT-Dop was able to measure implicit attitudes toward doping and was stable across time. Significant correlations between the computerized and p&p versions confirmed the construct validity. The p&p IAT-Dop showed several advantages over the computerized version (Lemm et al., 2008), including lower cost and ease of administration. By offering accurate measures and an easier, faster, and cheaper way to measure doping attitudes, this tool should contribute to the better assessment and understanding of the mechanisms related to doping, and it might be a useful new indicator in the evaluation of prevention programs.

Perceiving low-socioeconomic status (low-SES) groups as less human than high-SES groups contributes to justifying socioeconomic inequality. Despite this issue's relevance, previous research has not acknowledged the possible causes of this perceived humanity gap (differences in humanity between SES groups). In this project, we focus on analysing the possible influence of hierarchy-enhancing ideological variables on this gap. To do so, in a first correlational study (N = 765), we analyse the extent to which certain ideological variables predict the perceived humanity gap between low- and high-SES groups. Our results indicate that group dominance, system justification, and hostile classism are highly predictive of the humanity gap. In a second correlational study (N = 521) we found that the perceived humanity gap, the tendency to blame low-SES groups and praise high-SES groups for their economic standings, sequentially mediated the relationship among social dominance, system justification, and hostile classism with the support of social change policies. Finally, we manipulated each ideological variable in three equivalent studies (N = 631) to test its influence on the previous pattern of mediational results. The results confirmed the ideological variables' antecedent roles in the mediation analysis. Finally, we discuss the role of the ideological hierarchy variables in the maintenance of socioeconomic differences through (de)humanisation.

Are social network sites harmful to our well-being? Despite the topicality of this question, the literature is still inconsistent. Possible reasons include the over-use of cross-sectional designs, the centration on Facebook, and the omission of the different ways of using these platforms. Two preregistered experimental studies were therefore conducted to investigate the effects of passive and active usages of Facebook, Instagram, and Twitter on subjective well-being. For both the first (N = 244) and the second (N = 164) study, the results did not yield any significant effects of the type of social network sites and their passive-active usages on subjective well-being. In contrast, surfing content was associated with subjective well-being in Study 2: the more positive the content was, the more life satisfaction increased, and the more the negative affect decreased. Further investigation of this research question will be necessary in larger samples, including longitudinal studies that could provide greater ecological validity while testing the effects of social network sites in the long-term. These findings are therefore to be taken with caution; above all, they open new avenues of research to understand the relationship between social network sites and subjective well-being.

Most studies on physical attractiveness use (static) photos to rate physical attractiveness. This might not reflect how we perceive people in real, dynamic settings. Based on inconsistent previous studies, we conducted a meta-analysis to evaluate the ecological validity of photo-based attractiveness judgements by comparing them to dynamic stimuli ratings. Our literature search resulted in n = 46 effect sizes (k = 14 studies). Although the overall correlation between ratings of static and dynamic stimuli is high (r = 0.70, 95% CI [0.52; 0.81]), heterogeneity between studies is high as well (Q(45) = 168.27, p < 0.0001 and I² = 77.71%), which is mostly explained by unreported stimulus quality and within- versus between-rater designs. A Monte Carlo simulation indicated that the small correlations in some previous studies are potentially correlations which had not stabilized yet. Our findings support that the photo-rating method is an ecologically valid approach to assess physical attractiveness.

According to the primacy of morality hypothesis, moral traits are the most substantial contributor to - and when positive, always contribute positively to - global impressions of others. In three experiments (N = 413), we asked participants to form global impressions of the financial advisor (Study 1a), car mechanic (Study 1b), and physician (Study 1c). Contrary to the primacy of morality hypothesis, we showed that when people evaluate experts, they are guided primarily by experts' competence (solving or not solving clients' problems), not morality (moral or immoral intentions). The global impressions of the experts who made a mistake and did not solve clients' problems were negative regardless of the experts' moral or immoral intentions. However, the competent experts were continually assessed positively regardless of their good or bad intentions. The meta-analysis showed that the effect of manipulated intention on global impression was not significant. The results pose a challenge to the idea that moral behaviors are the most relevant when making global impressions of others.

The COVID-19 pandemic forced universities to move towards distance learning, requiring increased use of digital tools and more independent learning from students. In this context, the present study examined two previously documented barriers that contribute to social-class disparities in universities: the digital divide and the experience of cultural mismatch. Cultural mismatch refers to the disconnect between the highly independent cultural norms of universities and the interdependent cultural norms common among working-class students. Our goals are to (1) replicate the findings related to these barriers in a European context (2) provide pandemic-specific data related to these barriers, and (3) examine how the digital divide and cultural mismatch relate to psychological factors and learning behaviors necessary for academic success. Two thousand two hundred and seventy-five students in France answered questions about their digital access/use, self-construal, psychological factors (i.e., sense of belonging, self-efficacy, intentions to drop-out from the university), and learning behaviors (e.g., attending class, asking questions). Results showed that working-class students have less digital access and value interdependence more than their middle/upper-class peers, suggesting they are more likely to experience a cultural mismatch. Structural equation modeling revealed that both the digital divide and the experience of cultural mismatch undermines working-class students' psychological experience (e.g., belonging), which, in turn, hinders their learning behavior. The distance learning required by the pandemic led to increased needs for digital access and independence, and therefore more negatively affected working-class students, which could fuel and widen the social-class achievement gap.

This study used structural equation modelling to test how political orientations (self-reported placement on socially liberal-conservative and economically left-right continuums) could be predicted from basic worldviews (a generally humanistic vs. normativistic orientation) and basic personal values (concepts pertaining to desirable end states or behaviors) in conjunction with core political values (normative principles about functioning of society) in a population sample from Sweden. In general, political orientation was much more strongly predicted by social-focus values (conservation and self-transcendence), and only weakly predicted by personal-focus values (self-enhancement and openness to change). The results also showed that basic personal values in conjunction with core political values mediated the relationship between basic worldviews and political orientation.
