Gender-, race-, and income-based stereotype threat: the effects of multiple stigmatized aspects of identity on math performance and working memory function

This study compared the relative impact of gender-, race-, and income-based stereotype threat and examined if individuals with multiple stigmatized aspects of identity experience a larger stereotype threat effect on math performance and working memory function than people with one stigmatized aspect of identity. Seventy-one college students of the stigmatized and privileged gender, race, and income-level completed math and working memory pre-tests. Then, participants heard a moderately explicit stereotype threat-inducing prime. Next, participants took math and working memory post-tests. Stereotype threat effects were found on math performance on the basis of race and income-level, but not on the basis of gender. Stereotype threat effects were found on working memory function on the basis of gender, race, and income-level. For both measures, the income-based effects were the strongest. Results also suggest the possibility of multiple minority stereotype threat effects on math performance and working memory. More specifically, individuals with three stigmatized aspects of identity experienced significantly larger stereotype threat effects than those with zero-, one-, or two-stigmatized aspects of identity.     

Perception of individuality in bat vocal communication: discrimination between, or recognition of, interaction partners?

Different cognitive processes underlying voice identity perception in humans may have precursors in mammals. A perception of vocal signatures may govern individualised interactions in bats, which comprise species living in complex social structures and are nocturnal, fast-moving mammals. This paper investigates to what extent bats recognise, and discriminate between, individual voices and discusses acoustic features relevant for accomplishing these tasks. In spontaneous presentation and habituation–dishabituation experiments, we investigated how Megaderma lyra perceives and evaluates stimuli consisting of contact call series with individual-specific signatures from either social partners or unknown individuals. Spontaneous presentations of contact call stimuli from social partners or unknown individuals elicited strong, but comparable reactions. In the habituation–dishabituation experiments, bats dishabituated significantly to any new stimulus. However, reactions were less pronounced to a novel stimulus from the bat used for habituation than to stimuli from other bats, irrespective of familiarity, which provides evidence for identity discrimination. A model separately assessing the dissimilarity of stimuli in syllable frequencies, syllable durations and inter-call intervals relative to learned memory templates accounted for the behaviour of the bats. With respect to identity recognition, the spontaneous presentation experiments were not conclusive. However, the habituation–dishabituation experiments suggested that the bats recognised voices of social partners as the reaction to a re-habituation stimulus differed after a dishabituation stimulus from a social partner and an unknown bat.     

Landscape,nation and globe: Theoretical nuances in the analysis of Asian Christianity

This brief afterword comments on the papers from this special issue, arguing that each explores current complexities of interactions between national and transnational orientations, but also helps to nuance understandings of the global through the invocation of history. As a result, we not only observe the interplay between colonial and post-colonial regimes of religion and politics, but also gain an appreciation of transnational religious impulses that were in operation well before the last few decades of explicitly ‘global consciousness’. Christianisation has a significant history in the regions covered, but it cannot be understood through crude, unilinear models of development or progress.     

Meanings of movement,place and home at Walsingham

This paper examines the revival, over the past 100 years, of the Catholic pilgrimage site of Walsingham. It argues that, for some habitual pilgrims, the site is akin to a second ‘home’, constituting a place for ‘dwelling in movement’. Contemporary pilgrimage practices not only establish links between local parishes and the Walsingham shrines, but also incorporate specific forms of mobility that express connections with personal, collective and institutional representations of the past. An examination of the site encourages the blurring of analytical distinctions between ‘local’ and ‘visitor’, and also poses questions concerning the relationship between culture, place and forms of belonging.     

Developing a Brief Sensation Seeking Scale for Children: Establishing Concurrent Validity With Video Game Use and Rule-Breaking Behavior

Despite the importance of life-cycle models to sensation seeking research, past studies have typically focused on adolescents and adults. This is especially problematic for researchers studying the role of media use in the development of risky behaviors (e.g., violent video game consumption and aggressive behavior). To facilitate research with child populations, a brief sensation seeking scale for children (BSSS-C) is developed and validated with a sample of fourth, fifth, and sixth graders (N = 136). The BSSS-C is found to be internally reliable (α = .82) as well as a strong predictor of several risky child behaviors. Higher sensation seeking children were more likely to play video games, including violent subgenres (e.g., shooters), and to enjoy playing video games that contained specific acts of violence (e.g., weapon use). Higher sensation seekers were also more likely to engage in rule-breaking behavior, such as bringing prohibited cell phones to school. The results suggest that sensation seeking may be related to risky behavior at a very young age.     

The Sound of Social Cognition: Toddlers’ Understanding of How Sound Influences Others

Understanding others' perceptions is a fundamental aspect of social cognition. Children's construal of visual perception is well investigated, but there is little work on children's understanding of others' auditory perception. The current study assesses toddlers' recognition that producing different sounds can affect others differentially—auditory perspective taking. Two- and 3-year-olds were familiarized with two objects, one loud and one quiet. The adult then introduced a doll, and children were randomly assigned to one of two goals: either to wake the doll or to let her sleep. Children's object choice and the sound intensity they produced significantly varied in the predicted direction as a function of the goal task. These findings reveal young children's understanding of the effects of sound on other people's behavior and psychological states.     

Stress regulation and cognitive control: evidence relating cortisol reactivity and neural responses to errors

In this study, we tested the relationship between error-related signals of cognitive control and cortisol reactivity, investigating the hypothesis of common systems for cognitive and emotional self-regulation. Eighty-three participants completed a Stroop task while electroencephalography (EEG) was recorded. Three error-related indices were derived from the EEG: the error-related negativity (ERN), error positivity (Pe), and error-related alpha suppression (ERAS). Pre- and posttask salivary samples were assayed for cortisol, and cortisol change scores were correlated with the EEG variables. Better error–correct differentiation in the ERN predicted less cortisol increase during the task, whereas greater ERAS predicted greater cortisol increase during the task; the Pe was not correlated with cortisol changes. We concluded that an enhanced ERN, part of an adaptive cognitive control system, predicts successful stress regulation. In contrast, an enhanced ERAS response may reflect error-related arousal that is not adaptive. The results support the concept of overlapping systems for cognitive and emotional self-regulation.     

Body ideals in women after viewing images of typical and healthy weight models

Viewing thin models, pervasive in popular culture, is correlated with body dissatisfaction and anxiety in women. Whether or not the same is true when viewing healthy weight models is unknown. In this study we tested whether viewing healthy weight models increases the ideal female body size. Body image, anxiety, happiness and depression were measured in 44 female participants following viewing of images of thin or healthy weight models (within-subject separated by two weeks). We found that after viewing images of healthy weight models, women's body ideals (as measured by a participant-adjusted virtual model) were significantly larger than when the same women viewed images of very thin models. This effect was greatest in those women with the highest levels of baseline anxiety (as measured by the Hospital Anxiety and Depression Scale). These results suggest that viewing healthy weight models results in more healthy body ideals than those typically promoted through media.
