Assessing potency of high- and low-preference reinforcers with respect to response rate and response patterns

Previous research has suggested that the availability of high-preference stimuli may override the reinforcing efficacy of concurrently available low-preference stimuli under relatively low schedule requirements (e.g., fixed-ratio 1 schedule). It is unknown if similar effects would be obtained under higher schedule requirements. Thus, the current study compared high-preference and low-preference reinforcers under progressively increasing schedule requirements. Results for 3 of the 4 participants indicated that high-preference stimuli maintained responding under higher schedule requirements relative to low-preference stimuli. For 1 participant, high-preference and low-preference stimuli were demonstrated to be equally effective reinforcers under increasing schedule requirements. Implications with respect to rate of performance and response patterns are discussed.     

The who and when of internal gender discrimination claims: An interactional model

Although gender discrimination has been illegal in organizations since the passage of the Civil Right Act of 1964, individuals remain hesitant to claim internally by making members of their employing organization aware of gender discrimination. Yet surprisingly little research has examined the individual difference and contextual antecedents to internal discrimination claims. We advance an interactional model and hypothesize that gender identity (GI) and climate for diversity (CFD) will interact to predict internal claims of gender discrimination. Consistent with theory, laboratory and field studies demonstrate that strong GI individuals are more likely to make internal claims in organizations that value inclusion (i.e., positive CFD) than in organizations where discrimination is pervasive (i.e., negative CFD). In contrast to strong GI individuals, however, weak GI individuals are more likely to claim in a negative CFD than in a positive CFD. Implications for both individuals and organizations are discussed.     

Supervisor Appraisal as the Link Between Family–Work Balance and Contextual Performance

We examined the relationship between subordinates’ family to work balance (conflict and enrichment) and two dimensions of contextual performance (interpersonal facilitation and job dedication) reported by supervisors. Beyond the direct effects, we hypothesized that supervisor’s appraisals of employee conflict and enrichment would influence the supervisor’s contextual performance ratings. Data collected from a matched sample of 156 private sector employees and their supervisors indicated that the supervisor’s performance ratings were impacted by the supervisor’s appraisal of enrichment. However, the supervisor’s appraisal of conflict only mattered for interpersonal facilitation. There was a direct effect of subordinate’s conflict on both dimensions of contextual performance.     

On the nature of nonverbal working memory fractionation: a case of selective spatial short-term memory deficit in a child

Several lines of research on adult subjects demonstrate a visual/spatial fractionation of nonverbal working memory (WM), while behavioral studies on normal children support the idea of a static/dynamic distinction. In the present paper, we report a child (Z.M.) who failed on nonverbal WM tasks. To verify the nature of his defect, we carried out two experiments: in Experiment 1, Z.M. failed on spatial WM tasks but not on visual WM tasks and was not affected by the static/dynamic format of stimulus presentation; in Experiment 2, this visual/spatial dissociation was extended to the imagery domain. These results are best accounted for within the visual/spatial fractionation of WM and confirmed the role of WM in mental imagery. Clinical and rehabilitative implications of the present findings are also discussed.     

Prenatal Equality of Opportunity

In this article, we defend a normative theory of prenatal equality of opportunity, based on a critical revision of Rawls's principle of fair equality of opportunity (FEO). We argue that if natural endowments are defined as biological properties possessed at birth and the distribution of natural endowments is seen as beyond the scope of justice, Rawls's FEO allows for inequalities that undermine the social conditions of a property‐owning democracy. We show this by considering the foetal programming of disease and the possibility of germ‐line modifications. If children of lower socioeconomic background are more likely to develop in a poor foetal environment and germ‐line enhancements are available only to the rich, initial inequalities between the rich and the poor would grow, and yet FEO would be satisfied. In order to avoid the problem, we propose a revised FEO principle omitting any reference to the comparison of natural endowments. Our revised FEO requires that institutions mitigate social class effect from reproduction and gestation to the greatest extent compatible with parental freedoms and the value of the family.

Personality correlates of intimate partner violence subtypes: A latent class analysis

Perpetrators of intimate partner violence (IPV) represent a heterogeneous group who engage in a variety of aggressive acts which often co‐occur. However, few studies take this co‐occurrence into consideration. Failure to consider overlapping forms of IPV confounds understanding of risk factors for physical IPV, which in turn undermines identification, prevention, and intervention efforts. Though rarely studied in emerging adults, personality variables have recently been identified as important correlates of IPV. The primary aims of the current studies are to identify distinct subgroups of moderate and severe psychological and physical IPV and personality covariates of class membership. Two studies were conducted at different public regional universities in the northeast (n = 500; n = 497). Both samples were about two‐thirds female, approximately one‐half White, one‐fifth Black, and one‐quarter Latino, of any race. Latent Class Analysis identified three subgroups in both studies: low, moderate, and severe IPV. The severe and moderate IPV groups included those who reported threats and moderate physical IPV while the severe IPV group also included those who engaged in severe and injurious forms of physical IPV. Multinomial regression analysis showed that impulsive aggression discriminated moderate and severe from low IPV (Study 1), and more frequent emotionally abusive and controlling behavior, a hostile‐dominant interpersonal style and trait aggression discriminated among all three groups, with severe IPV having the greatest likelihood of controlling behavior and aggression (Study 2). IPV is represented by distinct subgroups that vary by severity of IPV with different personality covariates. General aggressive and domineering tendencies in relationships characterize those engaging in severe IPV.
