An improved spatial span test of visuospatial memory

In the widely used Corsi Block Test and Wechsler Spatial Span Tests, participants must reproduce sequences of blocks in the order touched by the examiner until two trials are missed at the same sequence length. The examiner records either the maximum number of blocks correctly reported or the total number of correct lists. Here, we describe a computerized spatial span test (C-SST) that uses psychophysical procedures to quantify visuospatial mean span (MnS) with sub-digit precision. Results from 187 participants ranging in age from 18 to 82 years showed that accuracy declined gradually with list length around the MnS (by ～30% per item). Simulation studies revealed high variance and biases in CBT and Wechsler measures, and demonstrated that the C-SST provided the most accurate estimate of true span (i.e., the sequence length producing 50% correct). MnS declined more rapidly with age than mean digit span (MnDS) measured in the same participants. Response times correlated with both MnS and MnDS scores. Error analysis showed that omission and transposition errors predominated, with weaker primacy and recency effects in spatial span than digit span testing. The C-SST improves the precision of spatial span testing and reveals significant differences between visuospatial and verbal working memory.     

Sexual Nature? (Re)presenting Sexuality and Science in the Museum

The past 15 years have seen dramatic changes in social norms around sex and sexuality in the UK and worldwide. In 2011, the London Natural History Museum (NHM) contributed to these debates by opening the temporary exhibition Sexual Nature, which aimed to provide ‘a candid exploration of sex in the natural world’ whilst also drawing in an under-represented audience of young adults. Sexual Nature provides an opportunity to explore Macdonald's ‘politics of display’ in the mutual construction of (public) scientific knowledge, society and sexuality, at a time of intense contestation over sexual norms. Whilst Sexual Nature both reflected and contributed to major reframings of sexuality and what science can say about it, the assumption that it would be possible to present this topic as morally neutral, reliable and uncontested, in line with traditions of public science, proved to be problematic. The language of the exhibition moved back and forth between human/animal similarity and difference, and between scientific and cultural tropes as the NHM tried to maintain epistemic authority whilst also negotiating the moral boundaries of acceptable sexual behaviour. The topic of sex pushed the museum far beyond its usual expertise in the natural sciences towards the unfamiliar territory of the social and human, resulting in an ad hoc search for, and negotiation with, alternative sources of expertise. Boon et al.’s co-curation approach to exhibition building has the potential to extend the NHM's audience-driven strategy, whilst also producing a more coherent and nuanced exhibition about the science of sex.

Power, Sex, and Violence: A Psychological Reconstruction of the 20th Century and an Intellectual Agenda for Political Psychology

Power, sex, and violence are three themes that characterize a good deal of 20th-century experience. Connections among these themes can be demonstrated through archival and field studies and by laboratory experiments, in the core disciplines of political psychology as well as in literature and art. Understanding and explaining this power-sex-violence fusion is an urgent theoretical and practical imperative. Two tasks are especially critical: understanding the nature of power-striving and how it might be tempered, and understanding how and why people construct "differences" among themselves. With its broad interdisciplinary tradition, its variety of traditional and innovative methods, and its links to the real world of human affairs, political psychology is well placed to assume this intellectual agenda.     

Sex differences in facial emotion perception ability across the lifespan

Perception of emotion in the face is a key component of human social cognition and is considered vital for many domains of life; however, little is known about how this ability differs across the lifespan for men and women. We addressed this question with a large community sample (N?=?100,257) of persons ranging from younger than 15 to older than 60 years of age. Participants were viewers of the television show “Tout le Monde Joue”, and the task was presented on television, with participants responding via their mobile devices. Applying latent variable modeling, and establishing measurement invariance between males and females and across age, we found that, for both males and females, emotion perception abilities peak between the ages of 15 and 30, with poorer performance by younger adults and declining performance after the age of 30. In addition, we show a consistent advantage by females across the lifespan, which decreases in magnitude with increasing age. This large scale study with a wide range of people and testing environments suggests these effects are largely robust. Implications are discussed.     

Conscientiousness but not agreeableness mediates females’ tendency toward being a morning person

Individuals differ in their chronotype, and some are identified as morning ones and others as evening ones. Earlier studies showed that women were higher on morningness, conscientiousness, and agreeableness. In this study, we aimed at exploring the mediational effects of conscientiousness and agreeableness in the relationship of gender and morningness‐eveningness. Participants were 669 university students. Results supported positive relationships between morningness and conscientiousness and agreeableness and between conscientiousness and agreeableness. Females were higher on all these three variables. Mediation analyses suggested that the effect of gender (here females) on chronotype (here morningness) was mediated by conscientiousness but not agreeableness so that after the mediation partially occurred, the gender's effect did not remain significant anymore. This study backed our hypothesis that conscientiousness might play a more pronounced role than the intrinsic diurnal rhythm concerning the sex differences in chronotype.     

Social Norms and Egalitarian Values Mitigate Authoritarian Intolerance Toward Sexual Minorities

In the United States, acceptance of sexual minorities (e.g., gay men and lesbians) has increased substantially since the early 1990s. This study examined whether authoritarians' attitudes have been influenced by the societal shift toward greater acceptance of sexual minorities. Using data from the American National Election Studies (ANES) collected between 1992 and 2012, we tested a model in which authoritarianism, endorsement of egalitarian values, and social norms shifting in the direction of tolerance predict individual attitudes toward sexual minorities and LGBT rights issues. Results indicated that (1) there was a subset of authoritarians who endorsed egalitarian values, (2) authoritarians in general became more tolerant (i.e., held less negative attitudes) toward sexual minorities between 1992 and 2012, and (3) “egalitarian authoritarians” held more positive attitudes toward sexual minorities than other authoritarians. The findings contribute to contemporary theory and research on authoritarianism, which is moving from a monolithic view of authoritarianism to one in which culture and core values activate and shape manifestations of authoritarian tendencies.     

Sex differences in attention to disgust facial expressions

Research demonstrates that women experience disgust more readily and with more intensity than men. The experience of disgust is associated with increased attention to disgust-related stimuli, but no prior study has examined sex differences in attention to disgust facial expressions. We hypothesised that women, compared to men, would demonstrate increased attention to disgust facial expressions. Participants (n?=?172) completed an eye tracking task to measure visual attention to emotional facial expressions. Results indicated that women spent more time attending to disgust facial expressions compared to men. Unexpectedly, we found that men spent significantly more time attending to neutral faces compared to women. The findings indicate that women’s increased experience of emotional disgust also extends to attention to disgust facial stimuli. These findings may help to explain sex differences in the experience of disgust and in diagnoses of anxiety disorders in which disgust plays an important role.
