Metamemory following childhood brain injury: A consequence of executive impairment

In this study, we investigated the influence of children’s level of executive functioning on two types of metamemory knowledge following a traumatic brain injury (TBI). For this purpose, 22 children (aged 7 to 14 years) who had sustained a moderate to severe TBI and 44 typically developing children were recruited. The children with TBI were divided into two groups according to the severity of their executive impairment. Injury severity was determined by the Glasgow Coma Scale (GCS) score on admission or by the duration of unconsciousness. All children were then tested on both their knowledge of general memory functioning and their level of memory self-awareness, respectively assessed using the total number of correct responses on an adapted version of a metamemory interview and a self-other discrepancy score on a questionnaire evaluating everyday memory abilities. Data analyses revealed that participants with TBI who suffered impaired executive functions demonstrated less general metamemory knowledge, and underestimated the frequency of their memory problems, compared with children with TBI who had preserved executive functions and with control participants. Considering the well-established effect of metamemory knowledge on people’s spontaneous implementation of strategies, the interest and the importance of these findings on both theoretical and clinical grounds are discussed.     

Malleability of implicit associations across development

The prevalence of implicit intergroup bias in adults underscores the importance of knowing when during development such biases are most amenable to change. Although research suggests that implicit intergroup bias undergoes little change across development, no studies have directly examined whether developmental differences exist in the capacity for novel implicit associations to form or change. The present study examined this issue among children ages 5–12. Results from over 800 children provided evidence that novel implicit associations formed quickly, regardless of child age, association type (evaluative or non‐evaluative) or the target of the association (social or non‐social). Moreover, the magnitude of these changes was comparable across conditions. Coupled with similar findings among adults, these data underscore the importance of first impressions in shaping implicit intergroup bias and provide further evidence that the acquisition of implicit associations is governed by a domain‐general mechanism that may be fully in place by age 5.     

Measuring dimensions of social climate among South African higher education students

We investigated the structure of social climate among university students to characterise the relative importance of personal and interpersonal factors. Participants were 266 students from a school of education of a large South African university (females = 66.5%; black = 53.0%, white = 25.9%; coloured = 7.5%, Asian/Indian = 6.0%; mean age = 28.71 years, SD = 10.51 years). The students completed the Experience of Social Climate Questionnaire (ESCQ). Exploratory principal component factor analysis of the data yielded a three component structure of social climate comprising of (i) Constructive interpersonal relationships, (ii) Unloving towards self, and (iii) Aggression perceptions of self. Relationships and aggression appear to define social climate in a higher education student population.     

Comparative prevalence of isolated sleep paralysis in Kuwaiti, Sudanese, and American college students

A questionnaire measuring the incidence of isolated sleep paralysis was administered to 527 Kuwaiti, 762 Sudanese, and 649 American college students in what was the first study assessing the prevalence of isolated sleep paralysis in two Middle Eastern countries. Using the item "unable to move," 28.8% of Kuwaiti, 29.9% of Sudanese, and 24.5% of American participants reported experiencing the disorder at least once. When a second item, "pressure to the chest," was also used, the respective percentages were 19.2%, 20.7%, and 11.4%. With both criteria, the Kuwaiti and Sudanese had a significantly greater prevalence than did the American students. The Kuwaiti and Sudanese students did not differ significantly from each other in the percentage who reported the symptoms.     

Adolescent Friendship as a Dynamic System: Entropy and Deviance in the Etiology and Course of Male Antisocial Behavior

A dynamic systems framework was applied to understand the influence of friendship on antisocial behavior from childhood (age 9-10) through adulthood (age 24-25) for Oregon Youth Study males (N = 206). Boys were videotaped interacting with a friend at ages 14, 16, and 18, and deviant content and interpersonal processes were independently coded. Conditional dyadic interpersonal processes were studied as a communication system and summarized by an index of information entropy (F. Attneave, 1959). High entropy scores represent disorganized, unpredictable patterns of interaction, whereas low entropy scores reflect an organized dialogue. Conversations of early-onset antisocial boys and their best friends were less organized and included more deviant content than those of well-adjusted controls. Prediction analyses, however, revealed an interaction between entropy and deviant talk. Consistent with expectation, males with well-organized interactions (i.e., low entropy) but elevated levels of deviant content were most likely to continue antisocial behavior into adulthood. Findings suggest that individual risk for maladaptation may be amplified by early adolescent friendship dynamics organized around deviance.     

The Efficacy of Behavioral Couples Therapy and Emotionally Focused Therapy for Couple Distress

Twenty treatment outcome studies, 13 of which evaluated behavioral couples therapy (BCT) and seven of which evaluated emotionally focused therapy (EFT) were reviewed, leading to the following conclusions. BCT leads to short and long-term gains for moderate to severe couple distress. In the long term BCT probably leads to no better outcomes than its constituent components—behavioral exchange training and communication and problem solving skills training. Addition of a cognitive therapy component to BCT or the use of a variety of treatment formats does not improve the efficacy of BCT. Integrative couples therapy and insight-oriented marital therapy may be more effective than BCT, but studies supporting this conclusion require replication. EFT leads to short and long-term gains for mild to moderate couple distress. Addition of a cognitive therapy component to EFT does not enhance its efficacy. EFT may be more effective than problem solving therapy and less effective than integrated systemic therapy, but the two studies supporting this conclusion require replication.Michael Byrne, PhD, is a Clinical Psychologist, Midland Health Board, Ireland; Alan Carr, PhD, is Director of the Clinical Psychology Training Programme, Department of Psychology, Arts Building, University College Dublin, Belfield, Dublin 4, Ireland (alan.carr@ucd.ie).

Consequences of organizational justice expectations in a selection system

This study examined several consequences of applicants' expectations of organizational justice at multiple stages in a selection process. The authors assessed the justice expectations of 1,832 job applicants prior to their participation in a testing process and examined how these expectations influenced their pretest attitudes and intentions as well as their perceptions of the testing process. Results revealed that applicants with higher expectations of justice reported higher levels of pretest motivation and more positive job acceptance and recommendation intentions. Justice expectations were also positively related to applicants' perceptions of justice in the testing process. Results provided some evidence that justice expectations have a moderating influence, such that justice perceptions have a greater influence on applicants' affective and cognitive states when expectations of justice are high. The theoretical and practical implications of these findings are discussed in the context of research on organizational justice and applicant perceptions.     

Deviant Peer Affiliation and Problem Behavior: A Test of Genetic and Environmental Influences

This study uses a multitrait, multimethod (MTMM) approach to investigate the genetic and environmental etiologies of childhood deviant peer affiliation (DPA) and problem behavior (PROB). The variability of genetic and environmental estimates by agent and method is also examined. A total of 77 monozygotic and 72 dizygotic twin pairs and each twin's close friend were assessed. The informants included parents, teachers, and twins, and the methods involved questionnaire reports and coder ratings of videotaped dyadic interactions between each twin and their close friend. Twin intraclass correlations and univariate models attributed DPA and PROB to genetic, and shared and nonshared environmental effects. Parameter estimates differed by rater and method, however. Results accentuate the imperative to attend to method effects inherent in MTMM behavioral geneticresearch.     

Effectiveness of an empirically supported treatment for social phobia in the field

This study examined the effectiveness of individual exposure combined with cognitive restructuring for social phobia in a clinical setting as well as the influence of sample restriction criteria on the effect size. Participants were 217 unselected patients with a primary diagnosis of social phobia who were treated by 57 therapists in four outpatient clinics of the Christoph-Dornier-Foundation of Clinical Psychology in Germany. Results 6 weeks after the end of therapy showed highly significant reductions in social phobic fears and avoidance as well as in general anxiety and symptoms of depression. However, patients who dropped out during therapy reported a significantly higher degree of depression. Results did not differ between the four outpatient clinics and are comparable with the average effect-sizes reported by meta-analytic studies of controlled efficacy research, using selected patients. Also, restricting the sample according to the selection criteria often applied in research settings did not result in higher effect sizes for the applied outcome measures. We conclude that individual cognitive behavioural therapy for social phobia can be transported from research settings to the field of mental health.
