Reinforcement sensitivity theory and symptoms of personality disorder: Specificity of the BIS in Cluster C and BAS in Cluster B

Gray’s reinforcement sensitivity theory, consisting of the behavioral inhibition (BIS) and behavioral activation (BAS), is frequently used to represent basic dimensions of psychopathology. However, notably few investigations have examined the link between the BIS/BAS and symptoms of personality disorder (PD). Although the Fight-Flight-Freeze System has emerged in the revised model as an important aspect of motivation, the BIS (linked to anxiety) and BAS (linked to impulsivity) have been the primary foci. The current investigation uses a dimensional measure of PD, the schedule for nonadaptive and adaptive personality (SNAP; Clark, 1993) applied to two independent samples of English-speaking participants: undergraduates (n = 276) and clinical patients (n = 47). Results were consistent across both samples, demonstrating that symptoms of Cluster B PDs are indicative of high BAS levels whereas symptoms of Cluster C PDs are characterized by high BIS levels.     

Differentiation and Intimate Partner Violence

ABSTRACT

This study explored the impact of differentiation of self on Intimate Partner Violence (IPV). We sought to determine if an individual's level of differentiation of self in a relationship adds to the variance accounted for in IPV perpetration by known risk factors, i.e., relational satisfaction, marital conflict, romantic jealousy, depression, and anxiety. Results indicated that differentiation of self in a relationship is a predictor for perpetration of physical intimate partner violence even after controlling for other known risk factors.     

Toddlers with Elevated Autism Symptoms Show Slowed Habituation to Faces

We explored social information processing and its relation to social and communicative symptoms in toddlers with Autism Spectrum Disorder (ASD) and their siblings. Toddlers with more severe symptoms of autism showed slower habituation to faces than comparison groups; slower face learning correlated with poorer social skills and lower verbal ability. Unaffected toddlers who were siblings of children with ASD also showed slower habituation to faces compared with toddlers without siblings with ASD. We conclude that slower rates of face learning may be an endophenotype of ASD and is associated with more severe symptoms among affected individuals.     

Maternal Emotional Distress,Abuse Risk,and Children's Symptoms: Child Gender as a Moderator of Parent Sensitivity as a Mediator

Mothers' distress is a correlate of their children's elevated behaviour problems and symptoms. Parenting practices have been shown to mediate these associations, but few studies have observed parenting or focused on parents at risk of child abuse. In this study of 269 high‐risk mothers and their young children (M = 4.2 years), structural equation modelling was used to test associations between mothers' distress and child externalizing and internalizing symptoms. Associations were expected to be partly indirect via mothers' observed low sensitivity, and child gender was expected to moderate associations. Also, mothers' child abuse risk was examined as a unique correlate of sensitivity and children's symptoms, and a moderator of associations of distress with sensitivity and symptoms. Associations showed a pattern of gender‐moderated mediation with the link between mothers' distress and internalizing mostly direct for boys, and equally direct and indirect via sensitivity for girls. The association of mothers' distress with externalizing was mostly direct for boys and girls. Mothers' child abuse risk was not uniquely associated with sensitivity or symptoms and did not moderate any associations. There were no differences in model paths between mothers referred from child welfare/mental health compared with other sources or self‐referred. Copyright © 2013 John Wiley & Sons, Ltd.     

Predictors of Health Locus of Control in Older Adults

Health locus of control has been shown to influence how individuals approach their health and health-related decisions. The present study examined the variables predictive of older adults’ health locus of control. A total of 261 adults aged 54–84 years completed a questionnaire about their health, approach to health, and background information about themselves. The results revealed that demographic indicators, health-related variables, and psychological variables—particularly health risk tolerance, future time perspective, health self-efficacy, and emotional instability—were related to older adults’ health locus of control. Findings have implications for programs aimed at modifying older adults’ health locus of control.     

Functional cerebral distance and the effect of emotional music on spatial rotation scores in undergraduate women and men

The influence of listening to music on subsequent spatial rotation scores has a controversial history. The effect is unreliable, seeming to depend on several as yet unexplored factors. Using a large sample (167 women, 160 men; M age = 18.9 yr.), two related variables were investigated: participants' sex and the emotion conveyed by the music. Participants listened to 90 sec. of music that portrayed emotions of approach (happiness), or withdrawal (anger), or heard no music at all. They then performed a two-dimensional spatial rotation task. No significant difference was found in spatial rotation scores between groups exposed to music and those who were not. However, a significant interaction was found based on the sex of the participants and the emotion portrayed in the music they heard. Women's scores increased (relative to a no-music condition) only after hearing withdrawal-based music, while men's scores increased only after listening to the approach-based music. These changes were explained using the theory of functional cerebral distance.     

Advice-taking as an unobtrusive measure of prejudice

A new unobtrusive measure of prejudice is proposed based on an advice-taking task. The computer-based task requires participants to find a token hidden behind one of two boxes. Prior to making their choice, however, someone (depicted by a name or a face) provides advice as to the token’s location. An unobtrusive measure of prejudice is derived by manipulating the advice-giver’s social group (e.g., male or female, Asian or White) and comparing the proportions of advice taken from each group. In Experiment 1, although the participants were not aware of it, they took more advice from males than from females. In Experiment 2, the relative proportion of advice taken from Asian versus White advice-givers correlated with responses to a news story pertaining to Asians. In Experiment 3, the relative proportion of advice taken from Asian versus White advice-givers correlated with scores on the Implicit Association Test (IAT) and predicted discriminatory behaviour, as indexed by the lost e-mail technique, better than other measures. In Experiment 4, scores on the advice task were uncontaminated by social desirability concerns and reactance and reflected the relative amounts of trust that people placed in different social groups. Taken together, these findings suggest that the advice task may be a useful tool for researchers seeking an unobtrusive measure of prejudice with predictive validity.     

Sex differences in the expression of depression: A developmental interaction effect

A 1982 study by Kleinke and colleagues indicated sex differences among college students in the expression of depression on the Depression Coping Questionnaire and Beck's Depression Inventory, with females showing a significantly greater tendency to label their feelings and symptomatology. Using the Structured Pediatric Psychosocial Interview (SPPI), we have examined 1015 public-school pupils ranging from 5 through 19 years of age. On the SPPI's depression-related scales of Unhappiness and Resentfulness, developmental age level appears to interact significantly with respondent's gender in determining the extensity of content expressed. Our results with older adolescents replicate the sex differences reported by Kleinke et al. (Sex Roles, 1982, 8, 877–889), but at earlier age levels such differences may not be salient. Therefore, the inclusion of a developmental parameter would appear especially important to the investigation of processes by which sex differences in the expression of affectivity become manifest by late adolescence.We wish to thank Mr. Gayle Seymour of the University of Akron Computer Center for his technical programming which culminated in graphics displayed in the present study.
