Effects of pretraining intrastriatal administration of p-chloroamphetamine on inhibitory avoidance

Pretraining systemic administration of p-chloroamphetamine (PCA) consistently produces retention deficits of inhibitory avoidance. This drug causes a widespread acute release of serotonin from cerebral neuronal terminals, but it is not known where in the brain PCA exerts its disruptive cognitive effects. The present experiment was aimed at determining whether the striatum is a site of action of this drug. PCA (5 microg) was infused, bilaterally, into the striatum of rats at 30, 15, or 5 min before training of inhibitory avoidance, and retention of the task was measured 24 h later. An inversely related time-dependent deficit was found. Together with the results from appropriate control groups, this result strongly suggest that systemic PCA produces its reported cognitive effects, at least in part, through its pharmacological action within the striatum.     

Reaching for Virtue, Stumbling on Sin: Concepts of Good and Evil in a Postmodern Era

Although our culture struggles to understand the origins and nature of good and evil behavior, the disciplines of psychology and psychoanalysis contribute to the discourse primarily indirectly. By examining early Judaism and Christianity, the authors seek to clarify the foundation of contemporary understanding of good and evil in Western society. Looking through the multiple filters of religion, philosophy, psychoanalysis and psychology, groundwork is laid for definitions of good and evil, which can be understood subjectively and measured objectively. As we investigate morality, will, and choice in the varied ologies and across time, we note how much emotion and volition are secondary in modern thinking about evil. Moreover, the place of will as a positive force in development is largely ignored, except by prescient thinkers like Otto Rank. To grasp evil's nature we need to integrate past with present, contrast conscious to unconscious desires, and allow that being bad is not necessarily unnatural or pathological, but can be a transitional stage in the growth of one's conscience.     

Validity and Reliability of the Interpersonal Competence Questionnaire: Empirical Evidence from an Italian Study

Interpersonal competence is crucial to human life, and poor social functioning is a typical feature of various psychopathological conditions. Given the relevance of the construct, increasing attention has recently been paid to the Interpersonal Competence Questionnaire (ICQ; Buhrmester et al. 1988), a 40-item self-report measuring five domains of interpersonal competence. To provide additional data on the cross-cultural adaptability of the ICQ, we developed an Italian version and investigated its psychometric properties with two independent student samples. Respondents were mostly women (about three quarters), ranging in age from 18 to 57. Study 1 (n?=?408) tested factor structure, internal consistency, and convergent validity. Study 2 (n?=?59) investigated test-retest reliability. Taken together, the results of both these studies provided support for the cross-cultural applicability of the ICQ, and revealed interesting associations between interpersonal competence and constructs such as well-being, emotion dysregulation and empathy.     

Acute Stress,Depression, and Anxiety Symptoms Among English and Spanish Speaking Children with Recent Trauma Exposure

A growing literature suggests the clinical importance of acute stress disorder symptoms in youth following potentially traumatic events. A multisite sample of English and Spanish speaking children and adolescents (N = 479) between the ages of 8–17, along with their caregivers completed interviews and self-report questionnaires between 2 days and 1 month following the event. The results indicate that children with greater total acute stress symptoms reported greater depressive (r = .41, p < .01) and anxiety symptoms (r = .53, p < .01). Examining specific acute stress subscales, reexperiencing was correlated with anxiety (r = .47, p < .01) and arousal was correlated with depression (r = .50, p < .01) and anxiety (r = .55, p < .01). Age was inversely associated with total acute stress symptoms (r = ?.24, p < .01), reexperiencing (r = ?.17, p < .01), avoidance (r = ?.27, p < .01), and arousal (r = ?.19, p < .01) and gender was related to total anxiety symptoms (Spearman’s ρ = .17, p < .01). The current study supports the importance of screening acute stress symptoms and other mental health outcomes following a potentially traumatic event in children and adolescents. Early screening may enable clinicians to identify and acutely intervene to support children’s psychological and physical recovery.     

Using the Networked Fire Chief for Ego-Depletion Research: Measuring Dynamic Decision-Making Effort and Performance

This study replicated ego-depletion predictions from the self-control literature in a computer simulation task that requires ongoing decision-making in relation to constantly changing environmental information: the Network Fire Chief (NFC). Ego-depletion led to decreased self-regulatory effort, but not performance, on the NFC task. These effects were also buffered by task enjoyment so that individuals who enjoyed the dynamic decision-making task did not experience ego-depletion effects. These findings confirm that past ego-depletion effects on decision-making are not limited to static or isolated decision-making tasks and can be extended to dynamic, naturalistic decision-making processes more common to naturalistic settings. Furthermore, the NFC simulation provides a methodological mechanism for independently measuring effort and performance when studying ego-depletion.     

Embodied image: Gender differences in functional and aesthetic body image among Australian adolescents

Perceptions of the body are not restricted to the way the body “looks”; they may also extend to the way the body “functions”. This research explores body image among male and female adolescents using the Embodied Image Scale (EIS), which incorporates body function into body image. Adolescents (N = 1526, male = 673, female = 853) aged 12–17 (M = 13.83, SD = 1.02), from 26 Western Australian high schools were surveyed. Information was gathered on pubertal timing, body mass index (BMI) and body image. Participants reported significantly higher value of, behavioral-investment in, and satisfaction with the functional dimension of the body compared to the aesthetic dimension. After controlling for age, pubertal timing, and BMI, females reported significantly higher aesthetic values and aesthetic behavioral-investment, and lower aesthetic satisfaction, functional values, functional behavioral-investment and functional satisfaction than male participants. Grade, pubertal timing and BMI category differences were also explored.     

Participant Retention in the Parents Matter! Program: Strategies and Outcome

We present a discussion of the literature addressing retention of ethnic minority samples in longitudinal studies. In addition, we describe the retention procedures implemented in the Parents Matter! Program (PMP), a community-based sexual risk reduction intervention for African American families. Finally, the results of PMP's retention strategies are presented.
