Sex differences in working memory

In two separate studies, sex differences in modal-specific elements of working memory were investigated by utilizing words and pictures as stimuli. Groups of men and women performed a free-recall task of words or pictures in which 20 items were presented concurrently and the number of correct items recalled was measured. Following stimulus presentation, half of the participants were presented a verbal-based distraction task. On the verbal working-memory task, performance of men and women was not significantly different in the no-distraction condition. However, in the distraction condition, women's recall was significantly lower than their performance in the no-distraction condition and men's performance in the distraction condition. These findings are consistent with previous research and point to sex differences in cognitive ability putatively resulting from functional neuroanatomical dissimilarities. On the visual working-memory task, women showed significantly greater recall than men. These findings are inconsistent with previous research and underscore the need for further research.     

The Effects of Victim’s Substance Use and Relationship Closeness on Mock Jurors’ Judgments in an Acquaintance Rape Case

Previous research has demonstrated that jurors perceive a female victim who is drunk at the time when she is sexually assaulted as less credible and more deserving of such punishment than a sober victim. In this experiment, we investigated the effect of an alleged acquaintance rape victim’s type of substance use and closeness of relationship with the defendant on the judgments of 152 student mock jurors. Participants read a case summary and answered a series of questions about their impressions of the actors and actions involved in the case. Participants perceived a victim who was sober at the time of the incident as more credible than a victim who was intoxicated due to illegal substance use (alcohol or LSD), and convictions were also most likely when the victim was sober. Women perceived the victim as more credible than men did. Higher victim credibility judgments were associated with less rape myth acceptance (RMA) on the part of participants.     

Thinking while talking: adults fail nonverbal false-belief reasoning

This experiment tested the ability of 81 adult subjects to make a decision on a simple nonverbal false-belief reasoning task while concurrently either shadowing prerecorded spoken dialogue or tapping along with a rhythmic shadowing track. Our results showed that the verbal task, but not tapping, significantly disrupted false-belief reasoning, suggesting that language plays a key role in working theory of mind in adults, even when the false-belief reasoning is nonverbal.     

The Adult Attachment Interview and self-reports of attachment style: an empirical rapprochement

Although 10 studies have been published on the empirical overlap of the Adult Attachment Interview (AAI) and measures of self-reported attachment style, results in this literature have been inconsistently interpreted in narrative reviews. This report was designed as a rapprochement of the AAI and attachment style literatures and includes 3 studies. Study 1 (combined N = 961) is a meta-analytic review showing that by J. Cohen's (1992) criteria (mean r = .09), the association between AAI security and attachment style dimensions is trivial to small. Study 2 (N = 160) confirms meta-analytic results with state-of-the-art assessments of attachment security and also examines attachment dimensions in relation to the Big 5 personality traits. Finally, Study 3 is an investigation of 50 engaged couples that shows that developmental and social psychological measures of attachment security predict somewhat distinct--though theoretically anticipated--aspects of functioning in adult relationships.

Assessing the Role of Body Image Coping Strategies as Mediators or Moderators of the Links Between Self-Objectification, Body Shame, and Well-Being

We examined self-objectification in relation to well-being, and the potential moderating versus mediating role of body image coping strategies (appearance fixing, avoidance, positive rational acceptance). Undergraduate women from southern Ontario, Canada (Sample 1, n?=?104; Sample 2, n?=?314) completed measures of depression, disordered eating attitudes, subjective well-being, and body-image coping. Self-objectification was related to greater depression, disordered eating attitudes, and lower subjective well-being. A two-stage mediation model was supported: Body shame and body image coping strategies (appearance fixing and avoidance) partially mediated the associations between self-objectification and outcomes; appearance fixing and avoidance partially mediated the associations between body shame and outcomes. Body image coping strategies did not moderate any of the relations between body shame and outcomes.     

Functional Consequences of HIV-Associated Neuropsychological Impairment

This review focuses on the “real world” implications of infection with HIV/AIDS from a neuropsychological perspective. Relevant literature is reviewed which examines the relationships between HIV-associated neuropsychological impairment and employment, driving, medication adherence, mood, fatigue, and interpersonal functioning. Specifically, the relative contributions of medical, cognitive, psychosocial, and psychiatric issues on whether someone with HIV/AIDS will be able to return to work, adhere to a complicated medication regimen, or safely drive a vehicle will be discussed. Methodological issues that arise in the context of measuring medication adherence or driving capacity are also explored. Finally, the impact of HIV/AIDS on mood state, fatigue, and interpersonal relationships are addressed, with particular emphasis on how these variables interact with cognition and independent functioning. The purpose of this review is to integrate neuropsychological findings with their real world correlates of functional behavior in the HIV/AIDS population.     

Subjective Distress to Violations of Trust in Mexican American Close Relationships Conforms to Evolutionary Principles

Sex differences in subjective distress to violations of trust in a close relationship were observed among Mexican American men and women. Imagining a partner’s emotional infidelity and other female-linked violations (for example, a partner who no longer desires to work) distressed a larger percentage of women than men. In contrast, imagining a partner’s sexual infidelity and other male-linked violations (for example, a partner who no longer makes an effort to look physically attractive) distressed a larger percentage of men than women. The results from two studies provided compelling evidence against a social–cognitive explanation of the sex differences and for an evolutionary psychology explanation based on men and women responding to threats to their sex-linked mating strategies.
