Attention Network Performance and Psychopathic Symptoms in Early Adolescence: An ERP Study

Reaction time (RT) and event-related potential (ERP) measures were used to examine the relationships between psychopathic symptoms and three major attention networks (alerting, orienting, and executive attention) among a community sample of youth. Antisocial Process Screening Device (APSD; Frick and Hare 2001) total and subscale scores were negatively correlated with ERP measures of attentional alerting, indicating that youth with psychopathic symptoms had difficulty using warning cues to prepare for upcoming targets. APSD total scores were not related to performance on measures of orienting or executive attention, although weaker executive attention was found among youth with higher scores on the Impulsivity subscale. These findings support attention-based models of psychopathy and provide evidence of specific deficits in attentional alerting among youth with psychopathic traits. Deficiencies in attentional alerting may be related to noradrenergic functioning and may have cascading effects on higher order cognitive and affective processing.     

A review of environmental enrichment as treatment for problem behavior maintained by automatic reinforcement

We reviewed studies that used environmental enrichment as treatment for problem behavior maintained by automatic reinforcement. A search of behavior analytic journals produced 71 publications with a total of 265 applications of environmental enrichment used alone or in conjunction with alternative behavior manipulations (e.g., prompting, reinforcement) and problem behavior manipulations (e.g., blocking, restraint). Environmental enrichment, as a sole intervention, was efficacious in 41% of the sample. Alternative behavior manipulations, problem behavior manipulations, and a combination of both improved the overall efficacy of environmental enrichment. We discuss factors that may influence the efficacy of environmental enrichment, current trends in research on this topic, and implications for both practitioners and researchers.     

Intermittent explosive disorder and other psychiatric comorbidity among court-referred and self-referred aggressive drivers

We assessed possible Axis I and Axis II disorders in two groups of aggressive drivers (n=20, court-referred; n=10, self-referred) and 30 non-aggressive driver controls, using the SCID and SCID-II. Aggressive drivers were more likely than controls to be positive for any Axis I and Axis II disorders. They were also more likely to meet the criteria for Intermittent Explosive Disorder (IED), current or past alcohol or substance abuse or dependence and Antisocial PD and Borderline PD. The self-referred aggressive drivers were more likely than court-referred aggressive drivers to meet the criteria for a current or past Anxiety Disorder. Re-analysis of aggressive driver data on the basis of presence or absence of IED revealed differences only in Axis II disorders: those with IED were more likely to meet the criteria for any Axis II disorder and Antisocial PD.     

Early abuse, psychiatric diagnoses and irritable bowel syndrome

In a population of 71 (57 female, 14 male) IBS patients seeking psychological treatment, we found expected levels of childhood sexual and physical abuse (57.7%) and expected levels of current Axis I psychiatric disorders (54.9%). Moreover, we found those who had been victims of early abuse had higher current Beck Depression Inventory scores. However, contrary to expectations, there were no significant associations between early abuse and current psychiatric disorder in this population, suggesting that those individuals with psychological distress are not exactly the same group with a history of abuse.     

Self-Esteem, Mood, and Intentions to Use Condoms: When Does Low Self-Esteem Lead to Risky Health Behaviors?

The authors assessed the interactive effects of self-esteem and mood on intentions to engage in unprotected sexual intercourse. Prior research has shown that people with low self-esteem tend to evaluate themselves unfavorably when in a negative mood state, whereas people with high self-esteem are less susceptible to changes in self-evaluation following a negative mood induction. The authors hypothesized that people who engage in negative self-evaluations may be more likely to report intentions to engage in unprotected sexual intercourse. Undergraduate females were randomly assigned to a positive or negative mood induction condition. Consistent with their hypotheses, the authors found that among participants who were in a negative mood state, those with low self-esteem were more likely to report intentions to have sexual intercourse without a condom than were those with high self-esteem. In contrast, among participants in a positive mood, there were no differences between those who were low and high in self-esteem.     

Gender differences in body size dissatisfaction among individuals with low,medium, or high levels of body focus

The authors designed the present study to test whether women reported higher levels of body dissatisfaction than did men even when the 2 genders were matched on a measure of degree of body focus. Sixty undergraduates (30 men, 30 women) were screened on attention-to-body-shape scores and divided into high, medium, and low body-shape-focus groups. The participants also completed questionnaires that provided information on age, education, vocabulary ability, levels of depression, and body-image assessment. The groups did not differ (ps > .05) on age, education, vocabulary ability, or levels of depression. However, women in all 3 body-shape-focus categories indicated a larger discrepancy between their real vs. ideal body images (p < .01) than did the men. In the high-body-focus group, there was an 11:1ratio between women's and men's reported real-ideal body-shape discrepancies. Women showed greater body dissatisfaction than did men, even when the genders were matched on a measure of body focus.     

Medical decision-making and minors: issues of consent and assent

The physician-patient relationship has been described as an egalitarian partnership in which patients and physicians work together to make healthcare decisions. Although adults receive considerable encouragement to become active participants in medical decision-making, children and adolescents often have little voice in such decisions and are granted limited access to confidential medical care. After a brief discussion of legal perspectives on informed consent, the present review examines the developmental literature on children and adolescents' capacities to make medical decisions that are informed, voluntary, and rational. The purposes and benefits of assent are identified. Remaining questions of how to evaluate capacity and balance parental and minor autonomy are explored.     

A controlled evaluation of cognitive behavioural therapy for posttraumatic stress in motor vehicle accident survivors

Seventy-eight motor vehicle accident survivors with chronic (greater than 6 months) PTSD, or severe sub-syndromal PTSD, completed a randomized controlled comparison of cognitive behavioral therapy (CBT), supportive psychotherapy (SUPPORT), or a Wait List control condition with two detailed assessments. Scores on the CAPS showed significantly greater improvement for those in CBT in comparison to the Wait List and to the SUPPORT conditions. The SUPPORT condition in turn was superior (p=0.012) to the Wait List. Categorical diagnostic data showed the same results. An analysis of CAPS scores including drop-outs (n=98) also showed CBT to be superior to Wait List and to SUPPORT with a trend for SUPPORT to be superior to Wait List. The CBT condition led to significantly greater reductions in co-morbid major depression and GAD than the other two conditions. Results held up well at a 3-month follow-up on the two active treatment conditions.     

Early adolescents' experiences with, and views of, Barbie

There has been a great deal of debate over the influence of Barbie dolls on girls' developing self-concept and body image. Two qualitative studies were conducted to gather information about early adolescents' experiences with, and perspectives on, the controversial toy. In Study 1, focus groups with twenty 6th-grade girls suggested that they have ambiguous feelings toward the doll and the feminine sexualized image it represents. Study 2 gathered essay responses from fifty 7th- and 8th-grade boys and girls regarding their experiences with, and opinions on, Barbie dolls. Participants reported both positive and negative feelings toward the doll and its influence on girls' development.
