Sexual pleasure is a key determinant of condom use. We developed and validated a male, event-level sexual pleasure scale (EMSEXpleasure) among a sample of condom-using men in the U.S. in order to facilitate improved measurement of sexual pleasure. Based on an expert panel process, a 12-item scale was developed. An online sample of 169 men who have sex with men and 162 men who have sex with women were recruited. Factor analysis yielded a two-factor solution that matched domains identified a priori by the expert panel, general pleasure and condom-specific pleasure, indicating internal validity of the instrument. One item was deleted from the scale due to poor validity performance. The overall EMSEXpleasure scale, and each subscale, had high (> 0.8) Cronbach’s alpha coefficients, indicating internal reliability. The scale demonstrated convergent validity, with theoretically related constructs associated both with individual scale items and with scale totals. Overall relationship quality (b 3.0, 95% CI 2.0, 4.0), sexual relationship quality (b 2.9, 95% CI 2.0, 4.0), foreplay quality (b 7.5, 95% CI 2, 13), positive feelings about condoms (b 18.8, 95% CI 15, 23), and erection problems while using condoms (b − 17.9, 95% CI − 22, − 14) were associated with the EMSEXpleasure scale in expected directions. The validated EMSEXpleasure event-level scale may be advantageous for future assessments of the ephemeral experience of sexual pleasure, including clinical trials of condoms and other interventions, because it can be used immediately after sex, potentially limiting recall error.

Recent evidence suggests that grammatical aspect can bias how individuals perceive criminal intentionality during discourse comprehension. Given that criminal intentionality is a common criterion for legal definitions (e.g., first-degree murder), the present study explored whether grammatical aspect may also impact legal judgments. In a series of four experiments participants were provided with a legal definition and a description of a crime in which the grammatical aspect of provocation and murder events were manipulated. Participants were asked to make a decision (first- vs. second-degree murder) and then indicate factors that impacted their decision. Findings suggest that legal judgments can be affected by grammatical aspect but the most robust effects were limited to temporal dynamics (i.e., imperfective aspect results in more murder actions than perfective aspect), which may in turn influence other representational systems (i.e., number of murder actions positively predicts perceived intentionality). In addition, findings demonstrate that the influence of grammatical aspect on situation model construction and evaluation is dependent upon the larger linguistic and semantic context. Together, the results suggest grammatical aspect has indirect influences on legal judgments to the extent that variability in aspect changes the features of the situation model that align with criteria for making legal judgments.

Social experience is an important predictor of disease susceptibility and survival in humans and other social mammals. Chronic social stress is thought to generate a proinflammatory state characterized by elevated antibacterial defenses and reduced investment in antiviral defense. Here we manipulated long-term social status in female rhesus macaques to show that social subordination alters the gene expression response to ex vivo bacterial and viral challenge. As predicted by current models, bacterial lipopolysaccharide polarizes the immune response such that low status corresponds to higher expression of genes in NF-κB-dependent proinflammatory pathways and lower expression of genes involved in the antiviral response and type I IFN signaling.
Counter to predictions, however, low status drives more exaggerated expression of both NF-κB- and IFN-associated genes after cells are exposed to the viral mimic Gardiquimod. Status-driven gene expression patterns are linked not only to social status at the time of sampling, but also to social history (i.e., past social status), especially in unstimulated cells. However, for a subset of genes, we observed interaction effects in which females who fell in rank were more strongly affected by current social status than those who climbed the social hierarchy. Taken together, our results indicate that the effects of social status on immune cell gene expression depend on pathogen exposure, pathogen type, and social history - in support of social experience-mediated biological embedding in adulthood, even in the conventionally memoryless innate immune system.
