Parent–Child Discrepancies in Report of Psychopathology: The Contributions of Response Bias and Parenting Stress

Summary: Two experiments were conducted to examine the relationship between conservatism and openness to experiences. In Study 1, the responses of 64 males and 60 females to the Conservatism Scale and the Coan (1972) Experience inventory were correlated. For the total sample, conservatism was significantly related to the total score of the Experience Inventory plus six of seven of the component scales. Study II examined the relationship between conservatism and the expressed willingness to volunteer for certain psychological experiments that were assumed to require more openness. Subjects were 91 males and 114 females from introductory psychology classes. High conservative subjects were less wiling to volunteer for the experiments that required more openness as compared to low conservative subjects. These results were discussed in the context of volunteer bias in psychological research.     

Reward boosts working memory encoding over a brief temporal window

Selection mechanisms for WM are ordinarily studied by explicitly cueing a subset of memory items. However, we might also expect the reward associations of stimuli we encounter to modulate their probability of being represented in working memory (WM). Theoretical and computational models explicitly predict that reward value should determine which items will be gated into WM. For example, a model by Braver and colleagues in which phasic dopamine signalling gates WM updating predicts a temporally-specific but not item-specific reward-driven boost to encoding. In contrast, Hazy and colleagues invoke reinforcement learning in cortico-striatal loops and predict an item-wise reward-driven encoding bias. Furthermore, a body of prior work has demonstrated that reward-associated items can capture attention, and it has been shown that attentional capture biases WM encoding. We directly investigated the relationship between reward history and WM encoding. In our first experiment, we found an encoding benefit associated with reward-associated items, but the benefit generalized to all items in the memory array. In a second experiment this effect was shown to be highly temporally specific. We speculate that in real-world contexts in which the environment is sampled sequentially with saccades/shifts in attention, this mechanism could effectively mediate an item-wise encoding bias, because encoding boosts would occur when rewarded items were fixated.     

MEASURING PERCEPTIONS OF THE WORKING ENVIRONMENT FOR WOMEN IN CORPORATE SETTINGS

This study developed a scale to measure individual perceptions of dimensions of the work organization that contribute to a supportive or hostile environment for women. Based on analysis of survey data from 398 respondents working in corporate settings, a scale was developed to measure five dimensions: Dual Standards & Opportunities; Sexist Attitudes & Comments; Informal Socializing; Balancing Work & Personal Obligations; and Remediation Policies & Practices. Women perceived their work environments as significantly more hostile on all five dimensions than did men. Scores on the scale were related to intent to stay with the organization: For both men and women, the friendlier they perceived the work environment for women to be, the longer individuals intended to stay at the company.     

MMPI-A structural summary variables: prevalence and correlates in an adolescent inpatient psychiatric sample

This study examined the prevalence and correlates of Archer and Krishnamurthy's MMPI-A Structural Summary (SS) dimensions in a sample of 632 adolescent psychiatric inpatients through a series of correlational analyses. These analyses examined the relationship between factor dimensions and categorically defined dimension elevations and external criterion measures that included chart review data, therapist ratings, chart diagnoses, and cognitive test performance. The SS dimensions provided additional interpretive yield for some within-normal-limits profiles. An examination of the pattern of correlations revealed small to moderate relationships between all SS variables and external criterion measures.     

Exploring the relationship between mentoring and counselling

In this article, the author examines the relationship between mentoring and counselling in the context of a mentoring relationship. Drawing on Clutterbuck and Megginson's (1999) Mentoring Executives & Directors, Butterworth-Heinemann, seven roles in mentoring, he explores how career functions of mentoring are incommensurable with psycho-social functions--following Kram's (1983) original terms--with a specific focus on counselling. This analysis raises some problems with the notion of counselling as part of the repertoire of the mentor, with the aim of the article not being to resolve these tensions but, instead, to put them forward as issues worthy of attention, debate and empirical investigation.     

Experimental evidence for differential susceptibility: dopamine D4 receptor polymorphism (DRD4 VNTR) moderates intervention effects on toddlers' externalizing behavior in a randomized controlled trial

In a randomized controlled trial we tested the role of genetic differences in explaining variability in intervention effects on child externalizing behavior. One hundred fifty-seven families with 1- to 3-year-old children screened for their relatively high levels of externalizing behavior participated in a study implementing Video-feedback Intervention to promote Positive Parenting and Sensitive Discipline (VIPP-SD), with six 1.5-hr intervention sessions focusing on maternal sensitivity and discipline. A moderating role of the dopamine D4 receptor (DRD4) variable-number tandem repeat (VNTR) exon III polymorphism was found: VIPP-SD proved to be effective in decreasing externalizing behavior in children with the DRD4 7-repeat allele, a polymorphism that is associated with motivational and reward mechanisms and Attention Deficit Hyperactivity Disorder (ADHD) in children. VIPP-SD effects were largest in children with the DRD4 7-repeat allele whose parents showed the largest increase in the use of positive discipline. The findings of this first experimental test of (measured) gene by (observed) environment interaction in human development indicate that children may be differentially susceptible to intervention effects depending on genetic differences.     

Why do implicit and explicit attitude tests diverge? The role of structural fit

Implicit and explicit attitude tests are often weakly correlated, leading some theorists to conclude that implicit and explicit cognition are independent. Popular implicit and explicit tests, however, differ in many ways beyond implicit and explicit cognition. The authors examined in 4 studies whether correlations between implicit and explicit tests were influenced by the similarity in task demands (i.e., structural fit) and, hence, the processes engaged by each test. Using an affect misattribution procedure, they systematically varied the structural fit of implicit and explicit tests of racial attitudes. As test formats became more similar, the implicit-explicit correlation increased until it became higher than in most previous research. When tests differ in structure, they may underestimate the relationship between implicit and explicit cognition. The authors propose a solution that uses procedures to maximize structural fit.     

Task complexity as a driver for collaborative learning efficiency: The collective working‐memory effect

This study investigated the differential effects of learning task complexity on both learning process and outcome efficiency of 83 individual and group learners in the domain of biology. Based upon cognitive load theory, it was expected that for high‐complexity tasks, group members would learn in a more efficient way than individual learners, while for low‐complexity tasks, individual learning would be more efficient. This interaction hypothesis was confirmed, supporting our premise that the learning efficiency of group members and individuals is determined by a trade‐off between the group's advantage of dividing information processing amongst the collective working memories of the group members and its disadvantage in terms of associated costs of information communication and action coordination.

Individuals with Fear of Blushing Explicitly and Automatically Associate Blushing with Social Costs

To explain fear of blushing, it has been proposed that individuals with fear of blushing overestimate the social costs of their blushing. Current information-processing models emphasize the relevance of differentiating between more automatic and more explicit cognitions, as both types of cognitions may independently influence behavior. The present study tested whether individuals with fear of blushing expect blushing to have more negative social consequences than controls, both on an explicit level and on a more automatic level. Automatic associations between blushing and social costs were assessed in a treatment-seeking sample of individuals with fear of blushing who met DSM-IV criteria for social anxiety disorder (n = 49) and a non-anxious control group (n = 27) using a single-target Implicit Association Test (stIAT). In addition, participants’ explicit expectations about the social costs of their blushing were assessed. Individuals with fear of blushing showed stronger associations between blushing and negative outcomes, as indicated by both stIAT and self-report. The findings support the view that automatic and explicit associations between blushing and social costs may both help to enhance our understanding of the cognitive processes that underlie fear of blushing.
