Working Memory Effects of Gap-Predictions in Normal Adults: An Event-Related Potentials Study

The current study examined the relationship between verbal memory span and the latency with which a filler-gap dependency is constructed. A previous behavioral study found that low span listeners did not exhibit antecedent reactivation at gap sites in relative clauses, in comparison to high verbal memory span subjects (Roberts et?al. in J Psycholinguist Res 36(2):175-188, 2007), which suggests that low span subjects are delayed at gap filling. This possibility was examined in the current study. Using an event-related potentials paradigm, it was found that low span subjects have an onset latency delay of about 200?ms in brain responses to violations of syntactic expectancies after the gap site, thus providing a time course measure of the delay hypothesized by previous literature.     

Locus of control as a contributing factor in the relation between self-perception and adolescent aggression

Researchers continue to debate the role of self-esteem in aggression, but research has shown a consistent association between narcissism and aggression in adults and adolescents [e.g., Barry et al., 2007; Bushman and Baumeister, 1998; Stucke, 2007]. The primary aim of the current study was to examine whether locus of control (LOC) moderated the relation between self-perception variables (i.e., self-esteem and narcissism) and aggression in adolescents. Participants were 174 youth (145 males, 26 females) between the ages of 16 and 19 who were enrolled in a voluntary residential program for youth who have dropped out of school. The results showed that LOC moderated the association between self-esteem and aggression such that low self-esteem was associated with higher levels of aggression for individuals with an external LOC. Contrary to expectations, LOC failed to moderate the narcissism-aggression relation. The implications of this study for understanding how self-perception is related to adolescent aggression are discussed.     

An integrated approach to delivering exposure-based treatment for symptoms of PTSD and depression in OIF/OEF veterans: preliminary findings

Combat-exposed military personnel from the wars in Iraq and Afghanistan report high rates of PTSD and associated psychiatric problems. A formidable body of research supports exposure therapy as a front-line intervention for PTSD; however, relative to studies of civilians, fewer investigations have evaluated the effectiveness of exposure therapy using military samples. Specifically, barriers to care (e.g., stigma associated with receiving mental health services ) may compromise utilization of evidence-based psychotherapy. As such, researchers have argued that veterans with PTSD may require an integrated and innovative approach to the delivery of exposure techniques. This paper presents the rationale for and preliminary data from an ongoing clinical trial that compares the home-based telehealth (HBT) application of a brief, behavioral treatment (Behavioral Activation and Therapeutic Exposure; BA-TE) for veterans with PTSD to the standard, in-person application of the same treatment. Forty OIF/OEF veterans with PTSD and MDD were consented, enrolled, and randomized to condition (BA-TE in-person, or BA-TE HBT) and symptoms of anxiety and depression were assessed at pre- and posttreatment. Participants in both conditions experienced reductions in depression, anxiety, and PTSD symptoms between pre- and posttreatment, suggesting that HBT application of an integrated PTSD treatment may be feasible and effective.     

Agentic and Communal Personality Traits: Their Associations with Depression and Resilience among Transgender Women

Research reports the perpetuation of communal traits by transgender women, possibly to affirm their core gender identity. Transgender women in the United States are nearly 6 times more likely than the general population to experience significant depressive symptoms. Studies among non-transgender individuals in the United States demonstrate that agentic traits are associated with less depressive symptoms, while studies on communal traits are more inconsistent in their association with indicators of depression. Our study’s central objective was to examine the associations of agency and communion with depression and resilience (i.e., personal competence and acceptance of self and life) among transgender women living part-time and full-time in the female gender role. Participants in the United States were recruited through online and offline purposive sampling. One hundred and twenty-two transgender women (primarily Caucasian; ages ranging from 22 to 75) completed a web-based questionnaire. Results indicated that agentic and communal traits were significantly associated with decreased symptoms of depression and increased levels of resilience. One component of resilience – acceptance of self and life – mediated the relationship between agentic/communal traits and depression, however, for communal traits this pattern was only found for transgender women living in the female role full-time. There were no significant differences on depressive symptoms and one component of resilience - personal competence – among transgender women living full-time compared to transgender women living in the female role part-time. Transgender women living full-time in the female gender role reported higher levels of agentic/communal traits and acceptance of self and life compared to those living part-time in the female gender role. Our findings are discussed in the context of mental health among transgender women.     

Multiple trials may yield exaggerated effect size estimates

Published psychological research attempting to support the existence of small and medium effect sizes may not have enough participants to do so accurately, and thus, repeated trials or the use of multiple items may be used in an attempt to obtain significance. Through a series of Monte-Carlo simulations, this article describes the results of multiple trials or items on effect size estimates when the averages and aggregates of a dependent measure are analyzed. The simulations revealed a large increase in observed effect size estimates when the numbers of trials or items in an experiment were increased. Overestimation effects are mitigated by correlations between trials or items, but remain substantial in some cases. Some concepts, such as a P300 wave or a test score, are best defined as a composite of measures. Troubles may arise in more exploratory research where the interrelations among trials or items may not be well described.     

Promoting exercise behavior among Chinese youth with hearing loss: a randomized controlled trial based on the transtheoretical model

The transtheoretical model proposes that behavior change is experienced as a series of stages. Interventions tailored to these stages are most likely to be effective in progressing people through the model's hypothesized behavior change continuum. In this study, a stage-tailored, 12-week, exercise behavior intervention based on the transtheoretical model was conducted among a sample of 150 Chinese youth with hearing loss. Participants were randomized into an intervention or control group with all the core transtheoretical model constructs assessed pre- and post-intervention. Participants in the intervention group showed greater advances in their stage of exercise behavior change, decisional balance, and processes of change use compared to those in the control group. The intervention, however, was insufficient for increasing participants' self-efficacy for exercise behavior. The findings partially support the utility of the theory-based intervention for improving the exercise behavior of Chinese youth with hearing loss, while simultaneously helping to identify areas in need of improvement for future applications.     

Biased allocation of faces to social categories

Three studies show that social categorization is biased at the level of category allocation. In all studies, participants categorized faces. In Studies 1 and 2, participants overallocated faces with criminal features--a stereotypical negative trait--to the stigmatized Moroccan category, especially if they were prejudiced. On the contrary, the stereotype-irrelevant negative trait stupid did not lead to overallocation to the Moroccan category. In Study 3, using the stigmatized category homosexual, the previously used negative trait criminal--irrelevant to the homosexual stereotype--did not lead to overallocation, but the stereotype-relevant positive trait femininity did. These results demonstrate that normative fit is higher for faces with stereotype-relevant features regardless of valence. Moreover, individual differences in implicit prejudice predicted the extent to which stereotype-relevant traits elicited overallocation: Whereas more negatively prejudiced people showed greater overallocation of faces associated with negative stereotype-relevant traits, they showed less overallocation of faces associated with positive stereotype-relevant traits. These results support our normative fit hypothesis: In general, normative fit is better for faces with stereotypical features. Moreover, normative fit is enhanced for prejudiced individuals when these features are evaluatively congruent. Social categorization thus may be biased in itself.     

Higher-order factors of the Big Five predict exploration and threat in life stories

Research has not previously examined whether higher-order traits of the Big Five are related to characteristics of life story narratives. The current study explored possible links between the broad dispositions of Stability (comprising the shared aspects of Agreeableness, Conscientiousness, and Emotional Stability) and Plasticity (comprising the shared aspects of Extraversion and Openness) with narrative accounts of threat and exploration in the life-stories of 128 adults. Stability was inversely related to construals of threat in narratives, and Plasticity was positively related to exploration in narratives after controlling for the suppressor effects of demographic variables. These findings add to the research linking higher-order factors of the Big-Five to important domains as well as research linking dispositional traits to narrative identity.     

Psychopathic Traits of Dutch Adolescents in Residential Care: Identifying Subgroups

The present study examined whether a sample of 214 (52.8% male, M age = 15.76, SD = 1.29) institutionalized adolescents could be classified into subgroups based on psychopathic traits. Confirmatory Factor Analyses revealed a relationship between the subscales of the Youth Psychopathic traits Inventory (YPI) and the three latent constructs of the original model on which it is based. Latent Class Analyses showed that adolescents showing psychopathic traits could be classified into three subgroups. The first group showed low scores on the grandiose/manipulative dimension, the callous/unemotional dimension, and the impulsive/irresponsible dimension (normal group). The second group scored moderate on the grandiose/manipulative dimension and the callous/unemotional dimension and high on the impulsive/irresponsible dimension (impulsive, non-psychopathic-like group). The third group scored high on all three dimensions (psychopathy-like group). The findings revealed that the impulsive, non-psychopathic like group scored significantly higher on internalizing problem behavior compared to the normal group, while the psychopathy-like and the impulsive, non-psychopathic-like group both scored higher on externalizing problem behavior compared to the normal group. Based on a self-report delinquency measure, it appeared that the psychopathy-like group had the highest delinquency rates, except for vandalism. Both the impulsive and psychopathy-like group had the highest scores on the use of soft drugs.     

Biased Self-Perceptions,Peer Rejection,and Aggression in Children

This study examined whether children’s biased self-perceptions of peer acceptance are associated in a linear or curvilinear fashion with aggression, whether associations are moderated by peer rejection status, and whether associations apply uniquely to reactive aggression. Children in the 4th through 7th grades completed a self-report measure on their social functioning (SPPC; Harter 1982), and teachers reported on children’s social functioning and aggression. Self-perceptual bias was operationalized as the standardized residual difference between children’s self-perceptions and their teachers’ perceptions of their peer acceptance. Rejected status moderated associations between biased self-perceptions and reactive aggression. Among non-rejected children, biased perceptions were not significantly associated with reactive aggression. In contrast, among peer-rejected children, reactive aggression was elevated in those who greatly underestimated as well as in those who even modestly overestimated their peer acceptance. This pattern was observed whether or not proactive aggression was statistically controlled. In contrast, biased self-perceptions were not associated with proactive aggression for rejected or nonrejected children. Implications are discussed with regard to future research and potential interventions for aggressive children.
