PROSPECT (HE): An Evaluation of User Responses

The main features of PROSPECT (HE), a major new computer-aided guidance system for higher education institutions, are described. The results of its field trials within six higher education careers services show that the reactions of students and staff to the system are predominantly positive and that it has already established credibility with its users. There are, however, some 'tensions' between some of the principles on which the system is based: between matching and exploration; between coherence and flexibility; and between a phenomenological approach and an approach based on objective realism.     

The Analysis of Intervention Change in Children and Families: Methodological and Conceptual Issues Embedded in Intervention Studies

This article provides an overview of methodological and conceptual issues underlying the assessment of change during psychotherapy with children and families. Three central considerations are discussed: (1) What changes do we measure? (2) When do we measure change? (3) How do we measure change? The difficulties with the traditional methods of assessing change are highlighted, and suggestions for a new paradigm that calls for expansion of the nomological network relevant to the analysis of change, as well as the inclusion of more assessment points and more reliable and valid measures of the change process, are presented. Illustrations of key points are provided from the Adolescent Transitions Program, a theoretically based intervention program targeting high-risk youth.     

Subtyping children and adolescents with loss of control eating by negative affect and dietary restraint

OBJECTIVE: Research suggests that subtyping adults with binge eating disorders by dietary restraint and negative affect predicts comorbid psychopathology, binge eating severity, and treatment outcome. Little research has explored the validity and clinical utility of subtyping youth along these dimensions. METHOD: Children (aged 8-18 years) reporting loss of control eating (n=159) were characterized based upon measures of dietary restraint and negative affect using cluster analysis, and then compared regarding disordered eating attitudes and behaviors, and parent-reported behavior problems. RESULTS: Robust subtypes characterized by dietary restraint (n=114; 71.7%) and dietary restraint/high negative affect (n=45; 28.3%) emerged. Compared to the former group, the dietary restraint/high negative affect subtype evidenced increased shape and weight concerns, more frequent binge eating episodes, and higher rates of parent-reported problems (all ps<0.05). CONCLUSION: Similar to findings from the adult literature, the presence of negative affect may mark a more severe variant of loss of control eating in youth. Future research should explore the impact of dietary restraint/negative affect subtypes on psychiatric functioning, body weight, and treatment outcome.     

Temperament and intuition: A commentary on Feltz and Cokely

In this paper, we examine Adam Feltz and Edward Cokely’s recent claim that “the personality trait extraversion predicts people’s intuitions about the relationship of determinism to free will and moral responsibility” (INSERT REFERENCE). We will first present some criticisms of their work before briefly examining the results of a recent study of our own. We argue that while Feltz and Cokely have their finger on the pulse of an interesting and important issue, they have not established a robust and stable connection between extraversion and compatibilist-friendly intuitions.     

Longitudinal Evaluation of the Role of Academic and Social Impairment and Parent-Adolescent Conflict in the Development of Depression in Adolescents with ADHD

Older adolescents with attention-deficit/hyperactivity disorder (ADHD) have a significantly increased likelihood of developing comorbid depression. It is important to evaluate factors during the early adolescent period that may contribute to this risk. A predominant theory is that impairment and failure experiences lead to the development of low-self efficacy and depression, and that parent and family factors also play a role. In a sample of 326 young adolescents with ADHD (Mage?=?12), the present study evaluated whether parent-adolescent conflict mediated the association between social and academic impairment and the development of depression. This study builds upon prior work by evaluating these associations longitudinally and by using a multi-rater approach, including the parent, adolescent, and teacher perspectives. Social and academic impairment directly predicted depression controlling for baseline levels of depression and change in ADHD symptoms. The association between social impairment and depression was partially mediated by parent-adolescent conflict. Mediation through conflict was not found for academic impairment, and the association between academic impairment and depression was no longer significant when accounting for conflict. These findings highlight the importance of social impairment in the development of depression in adolescents with ADHD. Caregivers may play an important role in determining whether adolescents with ADHD internalize social impairment and failure experiences and develop depressive symptoms. Implications of these findings in terms of the importance of interventions focused on parent-adolescent conflict are discussed.     

An evaluation of a required computer-applications course for psychology majors

This study describes and evaluates a psychology course specifically focused on computer skills for undergraduate psychology majors. Learning by 136 undergraduates was evaluated on a 57-item objective test. Mean posttest scores were significantly higher than the mean pretest scores in all classes across all topic areas.     

Both exposure to a novel context and associative learning induce an upregulation of AKAP150 protein in mouse hippocampus

A-kinase anchoring protein 150 (AKAP150) is a multi-enzyme signaling complex that coordinates the action of PKA, PKC, and PP2B at neuronal membranes and synapses. We measured levels of AKAP150 protein in the hippocampus 6h after training mice in a contextual fear conditioning paradigm. In contextual fear conditioning mice learn to associate a context with a footshock presentation. Mice were divided in four experimental groups with different training protocols: naive, no footshock exposure, immediate footshock exposure, and footshock 3min after exposure to the context. We found that AKAP150 protein levels were increased upon exposing mice to the novel context independent of the training protocol. However, when the animals were habituated to the experimental context, only mice that learned to associate the context with the footshock showed an upregulation of AKAP150. We suggest that upregulated levels of AKAP150 contribute to processing the exposure to a novel context and associative learning.     

Nesting of Focal Within Peripheral Vision Promotes Interactions Across Nested Time Scales in Head Sway: Multifractal Evidence From Accelerometry During Manual and Walking-Based Fitts Tasks

Nesting is a major cornerstone in ecological theorizing about visual perception, through both nesting of surface layout in locomotory movements and nesting of visually available surfaces within each other, from focal to peripheral vision. This work sought to probe these nesting relationships by examining the effects of the visual periphery on the strength of interactions among nested time scales in head sway. That is, we tested whether spatial nesting of the focal within peripheral visual fields stimulated nonlinear interactions amid temporal nesting. We examined head sway during 2 variants of the Fitts task, one involving manual pointing by seated participants and another involving walking comfortably with upright standing posture. All participants completed both tasks but were randomly assigned to experience these tasks with or without the visual periphery available. Multifractal analysis of head sway revealed that visual availability of the periphery promoted nonlinear interactions across nested time scales, but this effect depended on how much head sway extended across a plane than more ballistically along a single axis of variability.
