The Influence of Function,Topography, and Setting on Noncontingent Reinforcement Effect Sizes for Reduction in Problem Behavior: A Meta-analysis of Single-Case Experimental Design Data

Richman et al. (J Appl Behav Anal 48:131–152, 2015) completed a meta-analytic analysis of single-case experimental design data on noncontingent reinforcement (NCR) for the treatment of problem behavior exhibited by individuals with developmental disabilities. Results showed that (1) NCR produced very large effect sizes for reduction in problem behavior, (2) NCR implemented with the functional reinforcer resulted in a slightly larger effect size compared to NCR using nonfunctional reinforcers, and (3) schedule thinning for the delivery of reinforcers typically produced temporary and modest increases in levels of problem behavior. The purpose of the current study was to conduct follow-up analyses to determine whether treatment implementation setting, topography, or the function of problem behavior influenced the treatment effect size for problem behavior exhibited by individuals with developmental disabilities. Follow-up analyses showed that NCR effect sizes were very similar across inpatient and outpatient settings and across aggression and property destruction versus self-injurious behaviors. Results showed that NCR effect size for treatment of problem behavior maintained by a form of social reinforcement was slightly greater than problem behavior maintained by automatic reinforcement. Results are discussed in terms of applying NCR in school settings as an initial treatment for problem behaviors that can interfere with academic, adaptive, and vocational skill acquisition for students with developmental disabilities.     

Gender Role Orientation and Performance on Stereotypically Feminine and Masculine Cognitive Tasks

Nash (1979) argued that people tend to perform better on cognitive tasks when their gender-related self-concept is consistent with the stereotyping of the tasks. In order to evaluate Nash's hypothesis, participants were administered the S&M Mental Rotation Task, the Controlled Word Association Test, and the Bem (1974) Sex Role Inventory (BSRI). In men gender role orientation was significantly related to performance on the verbal task, with the critical factor being androgyny. When femininity and masculinity were assessed individually, femininity was found to be significantly related to the verbal task in men only. In women there was no significant variability across the gender role types in relation to performance on either task. These findings suggest that the importance of gender is dependent on the task and participants' sex. Nash's hypothesis was not supported for the mental rotation task.     

GENDER DIFFERENCES IN LEADER EMERGENCE PERSIST EVEN FOR DOMINANT WOMEN: AN UPDATED CONFIRMATION OF ROLE CONGRUITY THEORY

Role congruity theory predicts that women will be less likely than men to emerge as leaders when expectations for the leader role are incongruent with gender stereotypes. A 2 × 2 × 3 design that crossed the sex of the dominant partner, mixed- and same-sex dyads, and masculine, feminine, and neutral tasks involved 120 dyads of unacquainted college students in which one partner scored higher in dominance. In same-sex partnerships, the dominant member consistently emerged as leader. In mixed-sex dyads, the gender typing of the task did not influence dominant male ascendance but it did affect women's. When the task was masculine-typed or neutral, less dominant men were more likely to emerge as the leader of the dyad, frequently being appointed by the dominant woman herself. Thus, even when women possess the agentic quality of dominance consistent with the leader role, the incongruence between masculinized task demands and gender stereotypes mitigate against women's leadership emergence.     

Exploration of Jewish Ethnic Identity

Despite a growing amount of research on the topic of ethnic identity, Jews, and the important aspects of a Jewish identity, have not been included in the multicultural and psychological literature. Using consensual qualitative research (C. E. Hill et al., 2005), the authors sought to gain an understanding of Jewish ethnic identity in 10 American young adults, ages 20–27, who identified as Conservative Jews. Six themes were identified: (a) perception of Jewish identity based in multiple influences, (b) personalization of a Jewish identity, (c) reinforcers of a Jewish identity, (d) challenges in holding on to Jewish identity, (e) critical incidents necessitating the expression of one's Jewishness, and (f) critical incidents necessitating the denial of one's Jewishness.     

The role of self-regulation in derogating attractive alternatives

The present research addresses the question of how romantically involved individuals are able to shield their ongoing romantic relationship from the temptation of attractive alternative partners. Specifically, two studies examined, and supported, the prediction that self-regulation promotes romantically involved individuals’ tendency to derogate attractive others as potential partners. Heterosexual participants responded to pictures of attractive and unattractive opposite-sex others by indicating their interest in these others as potential partners. In both studies the possibility for self-regulation exertion was manipulated (by means of self-regulation depletion in Study 1, and time-pressure in Study 2). When self-regulatory resources were relatively high, romantically involved participants exhibited less interest in attractive opposite-sex others than non-involved participants. However, when self-regulatory resources were low, interest in attractive opposite-sex others did not differ between romantically involved and non-involved participants.
