Perinatal Factors, Parenting Behavior, and Reactive Aggression: Does Cortisol Reactivity Mediate this Developmental Risk Process?

Little is known about the mechanisms of action that link perinatal risk and the development of aggressive behavior. The aim of this study was to examine whether perinatal risk and parenting interacted to specifically predict reactive aggression, as opposed to general aggressive behavior, and to examine cortisol reactivity as a mediator of this developmental risk process. In a community sample of 99 elementary school-aged children, prenatal risk was measured by a count of minor physical anomalies (MPAs), reactive aggression was measured by laboratory observations of aggression in response to provocation, and general aggression was measured by parent report. Cortisol reactivity was not found to mediate the association between MPAs and reactive aggression or general aggression. However, MPAs were found to interact with parenting behaviors to predict reactive aggression and general aggression, as well as cortisol reactivity. Specifically, as the deficits in parenting increased, MPAs became more strongly and positively associated with reactive aggressive and general aggressive outcomes. Similarly, in cases of poor parenting behaviors, MPAs were positively associated with higher cortisol reactivity. Implications for theory and prevention are discussed.     

The Role of Incentive Framing on Training and Transfer of Learning in a Visual Threat Detection Task

We examined the effects of different incentives on skill acquisition and transfer during threat detection in airline luggage screening. The incentives were presented within positive (gains) or negative (losses) frames, and points were given or taken away accordingly during training (with familiar targets) and transfer (to novel targets). During training, incentives exerted a more beneficial effect on skill acquisition than training without incentives. During transfer, incentives benefitted performance largely when presented as losses or penalties. Incentives framed as gains primed participants to say ‘yes’ more often leading to a high ratio of false positives; however, incentives framed as losses lead participants to become more selective in their ‘yes’ responses leading to a lower number of false positives but a comparable probability of correct detections. Interestingly, participants that received no training outperformed participants that received incentive‐based training, suggesting that incentives actually constrained rather than helped transfer of learning in this study.

Creating space for interdisciplinary and interagency learning: the Newham ‘responsiveness’ days

Family therapists in Newham's specialist child and adolescent mental health services describe an interdisciplinary and interagency training day for Newham's children's workforce; the workshop aims to develop co‐learning about communication and collaboration in the context of a rapidly changing service environment, driven by current national and local policy initiatives. The training team attempts to generate a rich learning context using three themes: networking, responsiveness and complexity. The workshop demonstrates that it is perhaps possible to embed complex communication discourses in brief, pragmatic training, enhancing collaboration between professionals in local networks.     

CHILDHOOD ANTECEDENTS OF ADULT WOMEN'S MASCULINITY, FEMININITY, AND CAREER ROLE CHOICES

This study explores the relationships among childhood activities, masculine and feminine characteristics, and career choices. Sixty–three career women and 62 homemakers ranging in age from 34 to 48 completed a retrospective survey of their childhood activities, interests, aspirations, and academic pursuits. The toys, games, activities, and aspirations listed by the subjects were then assigned masculinity and femininity scores and were used to predict (1) career choice (homemaker or career woman) and (2) current masculinity and femininity as measured by the Personal Attributes Questionnaire (PAQ). Adult masculinity was strongly predicted by childhood masculine interests and activities while adult femininity was only weakly predicted by childhood feminine interests and activities. Masculine interests/activities were more powerful in discriminating career women from homemakers than were feminine interests/activities. The results of this study indicate that childhood participation in sex–typed activities is associated with the adult personality characteristics of masculinity and femininity, and adult role choices. These results are discussed in light of longitudinal evidence that suggests that they reflect consistent life–long patterns.
