Finding Sunshine on a Cloudy Day: A Positive Affect Intervention for Co-Occurring Methamphetamine Use and HIV

Among sexual minority men (i.e., gay, bisexual, and other men who have sex with men) living with HIV, those who use methamphetamine experience profound health disparities. Affect Regulation Treatment to Enhance Methamphetamine Intervention Success (ARTEMIS) is an evidence-based, 5-session, individually delivered positive affect intervention adapted for sexual minority men living with HIV who use methamphetamine. ARTEMIS was designed to amplify the benefits of evidence-based substance use interventions such as contingency management (CM) with this high-priority population. Delivering ARTEMIS during CM has been shown to assist participants in reducing stimulant use, increasing positive affect, and achieving durable reductions in HIV viral load. We describe the theoretical underpinnings of the ARTEMIS intervention, provide details of the training and session protocols with a case example, and discuss implications for future applications in research and clinical settings.     

Nothing But Stereotypes? Negligible Sex Differences Across Creativity Measures in Science,Arts, and Sports Adolescent High Achievers

Previous research has focused on understanding when, why, and how sex differences in creativity occur, as results vary across samples, measures, and methodologies. In the current study we investigated sex differences in creativity among 984 high achieving adolescents in three expertise areas: Sciences, Arts, and Sports. Eight creativity indicators were analyzed: Alternative uses task (AUT) fluency; creative self-efficacy (CSE); intraindividual strengths (difference between CSE and AUT Fluency); five self-reported creativity scales: Self/everyday, scholarly, performance, mechanical/scientific, artistic. The results showed negligible sex differences ( $n_{\mathrm{p}}^2$ = .01), with females performing better in AUT Fluency and males self-rating their CSE higher. No sex differences were found in self/everyday, scholarly and performance creativity. Males self-rated their mechanical/scientific creativity ( $n_{\mathrm{p}}^2$ = .06) higher than females; while females self-rated their artistic creativity ( $n_{\mathrm{p}}^2$ = .02) higher in comparison to males. Our results extend the existing literature by finding negligible sex differences in adolescent expert groups. However, some stereotypical differences emerged, for example, females with Sciences expertise rated their mechanical/scientific creativity lower than males with and even without Sciences expertise. Results call for further investigation into the links between sex differences, expertise, and specific creativity domains.     

Identifying and explaining apparent universal sex differences in cognition and behavior

With growing recognition that there are universal sex differences in cognition and behavior, four theories have been proposed to account for these differences: the founder effect theory, the social structuralist theory, the evolutionary theory, and the evolutionary neuroandrogenic (ENA) theory. The latter of these theories is described in considerable detail as offering an explanation for most of 65 recently identified apparent universal sex differences (AUSDs) in cognition and behavior. Regarding “ultimate causes” (why), ENA theory asserts that (a) evolutionary-genetic factors incline females to bias their mate choices toward males who are loyal and competent provisioners of resources and (b) males are merely a genetic variant on the female sex selected for responding to female mating biases. In terms of “proximate causes” (how), the theory maintains that high exposure to androgens has evolved to alter the male brain functioning in two specific ways relative to most female brains: (a) suboptimal arousal and (b) a rightward shift in neocortical functioning. These two functional patterns are described and hypothesized to incline males and females to learn differently in many respects. The most fundamental differences involve males learning ways of either complying with or circumventing female mate preferences. Numerous universal sex differences in cognition and behavior are hypothesized to result from these evolved neurohormonal factors, including most of the 65 AUSDs herein summarized in seven categorical tables.     

Sexual arousal and the pursuit of attractive mating opportunities

From an evolutionary perspective, sexual arousal may function, in part, to motivate the pursuit of attractive mating opportunities. We designed a study to test three aspects of this hypothesis. Several hundred heterosexual men and women completed a short survey about sexual arousal in response to a casual sex mating opportunity. We replicated previous research documenting that men report greater sexual arousal than women in response to a short-term mating opportunity. We argue that it is unlikely that a “downplaying of alternatives” psychology evolved, whereby mated individuals rate opposite-sex targets as less attractive than do unmated individuals, but instead that men and women have a relationship-seeking psychology, motivating them to pursue attractive mating opportunities. The results supported this relationship-seeking psychology rather than a downplaying alternatives psychology. Discussion addresses directions for future research on the motivational properties of sexual arousal.     

Investigating the Role of Religion‐Supported Secular Programs for Explaining Initiation into First Sex

Research finds that religious youth, compared to less religious youth, are more likely to delay their sexual debut (sometimes until marriage). This study is one of the first to examine the influence of involvement in religion‐supported secular activities for shaping initiation into vaginal sex. Does involvement in religion‐sponsored secular programs produce any health‐related benefits for youth? Using two waves of data from the National Study of Youth and Religion this study finds that among teens who have engaged in some of the precursors to first sex, namely, sexual touching, involvement in religion‐sponsored secular activities is associated with lower odds of having first sex between W1 and W2. Conservative attitudes about sex outside of marriage explain, in part, the relationship. Conversely, network overlap, the number of friends who belong to a youth group, and pressure from friends and partners to have sex do not significantly mediate the relationship.     

The Influence of Sex,Gender, Self-Discrepancies,and Self-Awareness on Anger and Verbal Aggressiveness Among U.S. College Students

Abstract

Among a sample of 445 U.S. college students, the authors examined the extent to which individual differences (e.g., sex, gender, self-discrepancies, self-awareness) explained anger tendencies and verbal aggressiveness. Regression analyses showed that (a) the tendency to repress anger (anger-in) was explained by masculinity, desire to be masculine, and public self-awareness, R ² = .19, F(11, 433) = 8.44, p < .001; (b) the tendency to express anger (anger-out) was explained by sex, masculinity, and public self-awareness, R ² = .17, F(11, 433) = 7.38, p < .001; and (c) willingness to be verbally aggressive was explained by sex, femininity, and private self-awareness, R ² = .32, F(11, 433) = 16.94, p < .001. In addition, different types of individual difference variables accounted for anger tendencies and verbal aggressiveness across sex and gender categories, suggesting that anger and verbal aggressiveness may be driven by different psychological processes across types of participants.     

The Effects of Intimacy and Target Sex on Direct Aggression: Further Evidence

The effects on aggression of target sex and relationship with the target were investigated using self‐report data. One hundred and seventy‐four participants (115 female) reported on acts of direct aggression in the last 2 years toward intimate partners, known and unknown same‐sex targets, and known and unknown opposite‐sex targets. Women's self‐reported aggression was higher toward partners than other targets, replicating previous findings regarding women's intimate partner aggression. Women's aggression was consistently higher toward same‐sex than opposite‐sex targets, but the effect of knowing the target was inconsistent. Men's self‐reported aggression was more frequent toward same‐sex than opposite‐sex targets—including intimate partners—and more frequent toward known than unknown targets. Results are discussed with reference to a partner‐specific reduction in women's fear, and sex differences in threshold for classifying someone as “known well.” Limitations of the present sample and suggestions for future work are discussed.

Perceived physical competence and body image as predictors of perceived peer acceptance in adolescents

The purpose of this study was to investigate the relationships among perceived physical competence, body image, and peer acceptance. Body image was considered as a possible mediator of the relationships between perceived physical competence and peer acceptance. Adolescents (N = 838) completed questionnaires. Direct and indirect effects of perceived physical competence and body image on perceived peer acceptance were explored using structural equation modelling. Gender differences were found and the structural mediation model was a reasonable fit to the data; the pattern of relationships in the model was different for adolescent males and females.
