The Association Between Age and Ethics-Related Issues in Using Social Media for HIV Prevention in Peru

Little research has focused on the ethical issues around using social media for HIV prevention in low- and middle-income countries, such as Peru. This study surveyed participants from the HOPE social media HIV intervention in Peru to assess their experiences and perceptions of ethical issues in the study and the impact of age on their experiences and perceptions. This study found that, compared to younger participants, older participants were more likely to express higher levels of understanding of the consent form and trust that other participants were real. Older participants also reported being less likely to benefit from learning about their HIV status. Findings suggest that age plays a role in participants’ experiences in a social-media-based HIV intervention.     

Premarital Sexual Debut in Emerging Adults of South Asian Descent: The Role of Parental Sexual Socialization and Sexual Attitudes

Ethnicity is an important factor in premarital sexual debut as norms regarding appropriate sexual conduct outside of marriage vary considerably across cultures. Emerging adults of South Asian descent living in Western societies are an important demographic group, yet little is known about the factors that contribute to variations in their premarital sexual debut. The goal of this study was to investigate the contributions of parental sexual socialization and attitudes toward premarital sexual behaviors to premarital sexual debut in emerging adults of South Asian descent. University students of South Asian descent (N = 87) aged 18–24 completed a questionnaire containing measures of parental attitudes toward premarital sexual behaviors, their own attitudes toward premarital sexual behaviors, and experience with oral sex and intercourse. Mediation analyses showed that perceptions of mothers’ as more permissive toward premarital sexual behaviors was associated with respondents reporting more permissive attitudes toward premarital sexual behaviors, which in turn was associated with a greater likelihood of having engaged in oral sex and intercourse. No significant effect was found for fathers. These findings suggest that parental sexual socialization may influence emerging adults of South Asian descent’s decision to engage in premarital sexual behaviors through the process of sexual attitudes formation.     

Religious perceptions of alcohol consumption and drinking behaviours among religious and non-religious groups

Evidence indicates that religious involvement is associated with lower levels of alcohol consumption. However, mechanisms underlying the specific effects of religion on alcohol behaviours are still not entirely clear. This study examined potential differences in religious perceptions of alcohol consumption (RePAC) among Christian, Buddhist, Muslim, and non-religious individuals, and between Catholic and Baptist Christian denominations. We also assessed whether these perceptions were associated with quantity and frequency of drinking. Participants (N?=?495; 79% female) aged 18 and above completed self-report measures of alcohol consumption and religious perceptions of alcohol use. Findings indicated that non-religious individuals and Buddhists reported higher RePAC scores (i.e., more favourable attitudes toward alcohol use), followed by Christians and then Muslims. Drinking quantity was more strongly associated with RePAC for Buddhists and Christians than the same association for non-religious participants. These results provide preliminary evidence linking religious perceptions of alcohol to drinking behaviours across religious affiliations.     

Isolation rearing effects on probabilistic learning and cognitive flexibility in rats

Isolation rearing is a neurodevelopmental manipulation that produces neurochemical, structural, and behavioral alterations in rodents that in many ways are consistent with schizophrenia. Symptoms induced by isolation rearing that mirror clinically relevant aspects of schizophrenia, such as cognitive deficits, open up the possibility of testing putative therapeutics in isolation-reared animals prior to clinical development. We investigated what effect isolation rearing would have on cognitive flexibility, a cognitive function characteristically disrupted in schizophrenia. For this purpose, we assessed cognitive flexibility using between- and within-session probabilistic reversal-learning tasks based on clinical tests. Isolation-reared rats required more sessions, though not more task trials, to acquire criterion performance in the reversal phase of the task, and were slower to adjust their task strategy after reward contingencies were switched. Isolation-reared rats also completed fewer trials and exhibited lower levels of overall activity in the probabilistic reversal-learning task than did the socially reared rats. This finding contrasted with the elevated levels of unconditioned investigatory activity and reduced levels of locomotor habituation that isolation-reared rats displayed in the behavioral pattern monitor. Finally, isolation-reared rats also exhibited sensorimotor gating deficits, reflected by decreased prepulse inhibition of the startle response, consistent with previous studies. We concluded that isolation rearing constitutes a valuable, noninvasive manipulation for modeling schizophrenia-like cognitive deficits and assessing putative therapeutics.     

Do positive illusions contribute to human well-being?

Psychologists such as Shelly E. Taylor have championed the idea that certain false beliefs, referred to as positive illusions, fulfill a significant role in contributing to human well-being. The goal of this article is to critically review the empirical evidence for this claim. The main concern, then, is whether the empirical evidence is conclusive in regard to the value of positive illusions for agents. The conclusion to be developed is that the latest psychological research is inconclusive in regard to the value positive illusions. This is due not only to evidence that draws into question the value of positive illusions for agents, but also due to methodological and conceptual problems with the positive illusion literature. Consequently, it could be the case that false beliefs contribute to agent well-being in specific situations, but it is difficult to claim that certain false beliefs are required for agent well-being.     

Facial redness,expression, and masculinity influence perceptions of anger and health

Past research has found that skin colouration, particularly facial redness, influences the perceived health and emotional state of target individuals. In the current work, we explore several extensions of this past research. In Experiment 1, we manipulated facial redness incrementally on neutral and angry faces and had participants rate each face for anger and health. Different red effects emerged, as perceived anger increased in a linear manner as facial redness increased. Health ratings instead showed a curvilinear trend, as both extreme paleness and redness were rated as less healthy than moderate levels of red. Experiment 2 replicated and extended these findings by manipulating the masculinity of both angry and neutral faces that varied in redness. The results found the effect of red on perceived anger and health was moderated by masculine face structure. Collectively, these results show that facial redness has context dependent effects that vary based on facial expression, appearance, and differentially impact ratings of emotional states and health.     

A minimal ingroup advantage in emotion identification confidence

Emotion expressions convey valuable information about others’ internal states and likely behaviours. Accurately identifying expressions is critical for social interactions, but so is perceiver confidence when decoding expressions. Even if a perceiver correctly labels an expression, uncertainty may impair appropriate behavioural responses and create uncomfortable interactions. Past research has found that perceivers report greater confidence when identifying emotions displayed by cultural ingroup members, an effect attributed to greater perceptual skill and familiarity with own-culture than other-culture faces. However, the current research presents novel evidence for an ingroup advantage in emotion decoding confidence across arbitrary group boundaries that hold culture constant. In two experiments using different stimulus sets participants not only labeled minimal ingroup expressions more accurately, but did so with greater confidence. These results offer novel evidence that ingroup advantages in emotion decoding confidence stem partly from social-cognitive processes.     

Optimal go/no-go ratios to maximize false alarms

Despite the ubiquity of go/no-go tasks in the study of behavioral inhibition, there is a lack of evidence regarding the impact of key design characteristics, including the go/no-go ratio, intertrial interval, and number of types of go stimuli, on the production of different response classes of central interest. In the present study we sought to empirically determine the optimal conditions to maximize the production of a rare outcome of considerable interest to researchers: false alarms. As predicted, the shortest intertrial intervals (450 ms), intermediate go/no-go ratios (2:1 to 4:1), and the use of multiple types of go stimuli produced the greatest numbers of false alarms. These results are placed within the context of behavioral changes during learning.
