Effects of expectancies of different reward magnitudes in transfer from noncontingent pairings to instrumental performance

In two experiments, rats received noncontingent pairings of two stimuli with food reward, one paired with small reward and the other with large reward, and received bar press training with large reward or with small reward. When the noncontingent stimuli (NS) were presented for test during subsequent rewarded bar pressing and during early extinction of bar pressing, responding for each group was faster in the presence of the NS which was paired with the same reward magnitude that group received in bar press training than to the NS which had been paired with a different reward magnitude. As extinction progressed, all groups responded more slowly in the presence of the NS which had been paired with the large reward than in the presence of the NS which had been paired with small reward. These results were interpreted as indicating that responding in the presence of an NS depends on: (i) whether the reward expectancy elicited by the NS has been conditioned to the instrumental response, and (ii) the relationship between the reward expected in the presence of the NS and that received in test.     

Information Seeking Within Organizations

In this article, both the literature on employee feedback‐seeking behavior and the literature on information seeking by organizational newcomers are reviewed. This review highlights the various motives that affect the decision of whether or not to seek information, shows how the strength of those motives is affected by both characteristics of the individual and characteristics of the organizational context, and reviews evidence that information seeking has beneficial outcomes. The author then offers an integrated model of antecedents, dynamics, forms, and outcomes of employee information seeking and concludes with suggestions for how future research can extend current understanding of employee information seeking.     

Improving Delivery Behaviors During Exposure for Pediatric OCD: A Multiple Baseline Training Trial With Community Therapists

This study tested whether a new training tool, the Exposure Guide (EG), improved in-session therapist behaviors (i.e., indicators of quality) that have been associated with youth outcomes in prior clinical trials of exposure therapy. Six therapists at a community mental health agency (CMHA) provided exposure therapy for 8 youth with obsessive–compulsive disorder (OCD). Using a nonconcurrent multiple baseline design with random assignment to baseline lengths of 6 to 16 weeks, therapists received gold-standard exposure therapy training with weekly consultation (baseline phase) followed by addition of EG training and feedback (intervention phase). The primary outcome was therapist behavior during in-session exposures, observed weekly using a validated coding system. Therapist behavior was evaluated in relation to a priori benchmarks derived from clinical trials. Additional outcomes included training feasibility/acceptability, therapist response to case vignettes and beliefs about exposure, and independent evaluator-rated clinical outcomes. Three therapists reached behavior benchmarks only during the EG (intervention) phase. Two therapists met benchmarks during the baseline phase; one of these subsequently moved away from benchmarks but met them again after starting the EG phase. Across all therapists, the percentage of weeks meeting benchmarks was significantly higher during the EG phase (86.4%) vs. the baseline phase (53.2%). Youth participants experienced significant improvement in OCD symptoms and global illness severity from pre- to posttreatment. Results provide initial evidence that adding the EG to gold-standard training can change in-session therapist behaviors in a CMHA setting.     

Human social defeat and approach–avoidance: Escalating social-evaluative threat and threat of aggression increases social avoidance

Basic research on avoidance by Murray Sidman laid the foundation for advances in the classification, conceptualization and treatment of avoidance in psychological disorders. Contemporary avoidance research is explicitly translational and increasingly focused on how competing appetitive and aversive contingencies influence avoidance. In this laboratory investigation, we examined the effects of escalating social-evaluative threat and threat of social aggression on avoidance of social interactions. During social-defeat learning, 38 adults learned to associate 9 virtual peers with an increasing probability of receiving negative evaluations. Additionally, 1 virtual peer was associated with positive evaluations. Next, in an approach–avoidance task with social-evaluative threat, 1 peer associated with negative evaluations was presented alongside the peer associated with positive evaluations. Approaching peers produced a positive or a probabilistic negative evaluation, while avoiding peers prevented a negative evaluation (and forfeited a positive evaluation). In an approach–avoidance task with social aggression, virtual peers gave and took money away from participants. Escalating social-evaluative threat and aggression increased avoidance, ratings of feeling threatened and threat expectancy and decreased ratings of peer favorableness. These findings underscore the potential of coupling social defeat and approach–avoidance paradigms for translational research on the neurobehavioral mechanisms of social approach–avoidance decision-making and anxiety.     

Embodied,Situated, and Co-Constructed: Young Sexual Minority Men’s Experiences of Intersectional Identity and Minority Stress

Intersectionality, minority stress, and social ecological theories have all been important frameworks for understanding mechanisms that create and maintain sexual and gender minority health disparities. In this study, we integrated these frameworks to guide a grounded theory examination of identity-related experiences in specific settings among 33 Black, White, and Latino young sexual minority cisgender men who lived in Chicago. Analyses identified four key categories: Racism Manifests in Context- and Sexual Minority-Specific Ways, Sexual Orientation Can Mean Feeling Safe and Seen or Threatened and Alone, Gender is a Matter of Self-Expression, and Bodies Are Not Always Made to Fit In. Participants reported both identity-based privilege and marginalization as well as unique forms of minority stress at the intersection of specific identities. Across these categories, participants’ experiences of their intersecting identities and associated forms of minority stress were embodied in their physical appearance, situated in specific neighborhoods and contexts, and co-constructed through their interpersonal interactions with others. Further, participants’ narratives provide powerful insights about the nuanced ways in which young sexual minority men understand and negotiate their lived experiences. Findings highlight how experiences of identity and minority stress are both intersectional and located within specific social ecological contexts, which has important implications for research, clinical practice, and advocacy.

Salivary testosterone and self-report aggressive and pro-social personality characteristics in men and women

Measures of salivary testosterone and the personality dimensions of aggression and pro-social behavior were obtained in 306 (155 male and 151 female) university students. Each participant provided two samples of saliva and completed ten self-report personality scales from multiple inventories. A factor analysis of the personality scales produced two factors, an aggression factor and a pro-social behavior factor. Men averaged five times the amount of salivary testosterone as women (99 pg/ml vs. 18.5 pg/ml) and rated themselves as more aggressive and less nurturant. Within each sex, testosterone was positively correlated with aggression and negatively correlated with pro-social personality. Structural equation modelling analyses suggested that a direct effect model best described the relationship between salivary testosterone and the latent personality dimensions of aggression and pro-social behavior. © 1996 Wiley-Liss, Inc.     

The Problem with Empirical Examination of the Use of Court-appointed Experts: A Report of Non-findings

This study was designed to examine the use of court-appointed experts as an alternative to privately retained experts in Dallas, Texas. Surprisingly, there has been little empirical study of court-appointed experts. Our findings suggest one reason for the lack of research. We found that court-appointed experts are used so infrequently that it makes empirical study difficult to conduct. We discuss the implications on this problem for future research.
