A time of change: Behavioral and neural correlates of adolescent sensitivity to appetitive and aversive environmental cues

Adolescence is a developmental period that entails substantial changes in affective and incentive-seeking behavior relative to both childhood and adulthood, including a heightened propensity to engage in risky behaviors and experience persistent negative and labile mood states. This review discusses the emotional and incentive-driven behavioral changes in adolescents and their associated neural mechanisms, focusing on the dynamic interactions between the amygdala, ventral striatum, and prefrontal cortex. Common behavioral changes during adolescence may be associated with a heightened responsiveness to incentives and emotional cues while the capacity to effectively engage in cognitive and emotion regulation is still relatively immature. We highlight empirical work in humans and animals that addresses the interactions between these neural systems in adolescents relative to children and adults, and propose a neurobiological model that may account for the nonlinear changes in adolescent behavior. Finally, we discuss other influences that may contribute to exaggerated reward and emotion processing associated with adolescence, including hormonal fluctuations and the role of the social environment.     

Therapeutic jurisprudence in the courts

Therapeutic jurisprudence is an emerging field of law and social science inquiry that explores the role of the law in fostering therapeutic or antitherapeutic outcomes. This article considers the relationship between therapeutic jurisprudence and court performance goals, examines applications of therapeutic jurisprudence in court settings, discusses the steps involved in incorporating therapeutic jurisprudence principles into the work of courts, outlines the pros and cons associated with practicing therapeutic jurisprudence primarily in specialized courts, and offers suggestions for fostering continued experimentation by courts.     

Improving the Credibility of Child Sexual Assault Victims in Court: The Impact of a Sexual Assault Nurse Examiner

The present study investigated the influence of a sexual assault nurse examiner's (SANE's) testimony on mock juror perceptions of a child or adolescent victim of child sexual assault. Community members (N = 252, 156 females) read a fictional criminal trial summary of a child sexual assault case in which the victim was 6 or 15 years old and the prosecution presented medical testimony from a SANE or a traditional registered nurse (RN), or did not present medical testimony. Mock jurors were more likely to render guilty verdicts when a SANE testified compared with the other two testimony conditions. In addition, pro-victim judgments (e.g., sympathy toward the victim) and negative defendant judgments (e.g., anger toward the defendant) mediated this relation. Finally, cognitive network representations of the case demonstrated that the RN and no-medical-testimony groups were similar and the SANE group was distinct from the other two conditions. We discuss these results in terms of the implications of SANE testimony in child sexual assault court cases. Copyright © 2015 John Wiley & Sons, Ltd.     

Do couples who play together stay together? A longitudinal dyadic examination of shared leisure,financial distress,and relationship outcomes

We examined whether shared leisure offers protection against negative associations between financial distress and relationship quality (satisfaction and commitment) for lower- and higher-income couples. We expected husbands' and wives' reports of shared leisure would be protective of the effects of financial distress (Time 2) on relationship satisfaction (Time 3) and commitment (Time 4) for higher-income couples (but not lower-income couples). Participants were drawn from a nationally representative, longitudinal study of US newly married couples. The analytic sample included both members of 1382 different-gender couples with data across the three sampled waves of data collection. Shared leisure was largely protective of the effects of financial distress on husbands' commitment for higher-income couples. For lower-income couples, higher shared leisure exacerbated this effect. These effects were only found at extreme levels of household income and shared leisure. When considering if couples who play together stay together, our findings suggest that it can, but it is critical to understand the financial situation of the couple and the resources they may have to support shared leisure activities. Professionals working with couples should consider their financial situation when making recommendation to engage in shared leisure, such as going out for recreation.     

Intimate partner violence exposure predicts PTSD treatment engagement and outcome in cognitive processing therapy

Intimate partner violence (IPV) exposure was examined as a predictor of treatment engagement (i.e., starting and completing therapy) and treatment outcome in 150 women taking part in a dismantling study of cognitive processing therapy (CPT) for posttraumatic stress disorder (PTSD; Resick et al., 2008). Results indicate that women in a current intimate relationship with recent IPV (i.e., past year) were less likely to begin treatment relative to women who reported past IPV only or no history of IPV. For women who began treatment, IPV exposure was not predictive of whether or not they completed treatment. Among women who began treatment, the frequency of IPV was associated with treatment outcome such that women who experienced more frequent IPV exhibited larger reductions in PTSD and depression symptoms over the course of treatment, but experienced similar levels of PTSD and depression severity at the 6-month follow-up. Findings highlight the importance of targeting treatment engagement among women who report recent IPV and suggest that women who have experienced frequent IPV respond well to CPT treatment in spite of their IPV experiences.     

Something to Shout About: A Simple,Quick Performance Enhancement Technique Improved Strength in Both Experts and Novices

In sports where an explosion of power or strength is necessary (e.g., weight lifting, tennis), athletes often yell or grunt to increase force production. Martial artists have used a similar technique for centuries called a kiap, but scientific evidence of its effectiveness is scarce. This study examined the effect of kiaping on strength and whether expertise influenced its effectiveness. Fifty (25 novices, 25 experts) martial artists completed a handgrip strength test under no kiap and kiap conditions. Performance for all participants was significantly better with the kiap (437.1 Newtons ± 94.9) than without (408.0 Newtons ± 90.6; p < .001).     

The Development of Discrimination of form and Area

The Time Competence Scale from the Personal Orientation Inventory was administered to 28 male and 47 female college students who then described their real and ideal self-concepts using the Interpersonal Check List. Self-actualizing individuals manifested greater congruence between their real and ideal self-concepts than did nonactualizing persons. Dominance was seen as a significantly more desirable integrative mechanism by the nonactualizing subjects. There was a nonsignificant trend in the desirability of an increase in acceptance as a function of the degree of self-actualization. Findings are discussed in terms of individuals' perceptions of congruence with their environment.     

Reasoning Ability in Young Children

The astrological assumption of personality differences among individuals born under different sun signs was investigated. Significant differences were obtained between sun sign groups on four of the 18 scales of the California Psychological Inventory (CPI) as follows: Communality, Socialization, Flexibility, and Femininity. The overall pattern of results based on F ratios, multiple comparisons between means, and estimates of strength of association was interpreted as showing no meaningful relationships between sun sign and scores on Communality, Socialization, and Flexibility. Adopting even the most conservative standards of inference, however, all of the test statistics employed indicated a powerful effect on the Femininity scale. Implications for future research were discussed.
