Aggressive Responding in the Laboratory Maintained by the Initiation of a Provocation-Free Interval

The Psychological Record - Four adults participated in an experiment designed to study how the duration of an interval free from provocation, following aggressive responding, affected the...     

The Brier Rule Is not a Good Measure of Epistemic Utility (and Other Useful Facts about Epistemic Betterness)

Measures of epistemic utility are used by formal epistemologists to make determinations of epistemic betterness among cognitive states. The Brier rule is the most popular choice (by far) among formal epistemologists for such a measure. In this paper, however, we show that the Brier rule is sometimes seriously wrong about whether one cognitive state is epistemically better than another. In particular, there are cases where an agent gets evidence that definitively eliminates a false hypothesis (and the probabilities assigned to the other hypotheses stay in the same ratios), but where the Brier rule says that things have become epistemically worse. Along the way to this ‘elimination experiment’ counter-example to the Brier rule as a measure of epistemic utility, we identify several useful monotonicity principles for epistemic betterness. We also reply to several potential objections to this counter-example.     

Social support,psychological vulnerability,and HIV risk among African American men who have sex with men

Previous research has suggested a need to understand the social-psychological factors contributing to HIV risk among African American men who have sex with men (MSM). We conducted individual in-depth interviews with 34 adult African American MSM to examine their personal experiences about: (i) sources of social support, (ii) psychological responses to the presence or absence of social support and (iii) influences of social support on sexual behaviours. The majority of participants described limited positive encouragement and lack of emotional support from family, as well as few meaningful personal relationships. Feelings of isolation and mistrust about personal relationships led many participants to avoid emotional intimacy and seek physical intimacy through sexual encounters. Findings highlight a need for multilevel interventions that enhance social support networks and address the social-psychological, emotional and interpersonal factors that contribute to HIV risk among African American MSM.     

Prosociality enhances meaning in life

A central feature of meaning in life is a consideration of more than oneself. We extend this logic to suggest that altruistically motivated prosociality – acting in ways that benefit others – is a self-transcending action that may provide meaning in life. Study 1 provided evidence of a relationship between self-reported prosocial behavior and meaning in life, even after statistically controlling for personality traits and self-esteem. Study 2 provided evidence that engaging in a prosocial action, via writing notes of gratitude, increased meaning in life. Study 3 provided evidence that individuals bolster perceptions of prosociality following threats to meaning. Study 4 suggested relationship satisfaction partially mediates the link between prosocial actions and meaning in life. These studies provide initial evidence that prosociality enhances meaning in life.     

Is modesty a subdomain of humility?

Although many scholars have sharply distinguished humility from modesty, several research teams recently conceptualized modesty as a subdomain of humility. In the present study, we compare these competing conceptualizations using confirmatory factor analyses. In Study 1, a model with general humility (i.e. second-order factor) predicting the subscales of the Relational Humility Scale (RHS) and the Modesty facet of the HEXACO-PI showed adequate fit; and modesty showed one of the stronger factor loadings on the higher order factor. In Study 2, we used a set of items designed to sharpen the potential distinction between modesty (i.e. interpersonal behavior involving moderating attention to self) and humility. Then, we tested a model with a general humility factor (i.e. second-order factor) predicting subscales of the RHS and modesty items. Once again, modesty items loaded strongly on the higher order factor.
