Rehabilitating the Stroke Patient through Patient-Family Groups

The observer's impact on the process and content of over fifty, two-day, intensive training groups was evaluated by leaders, members, and observers. There was general agreement across the three perspectives that the observer's influence was significant and potentially negative. The group members experienced the observer as more intrusive than did their leaders. The effects were predominantly indirect, and reflected in the content of group interactions both during and after the observer's visit. Results are discussed in terms of their clinical implications, and recommendations are made for how leaders may maximize the therapeutic potential of the observer's contributions.     

After-Contraction Phenomenon: Influences on Performance and Learning

Three experiments investigated the influence of an after-contraction phenomenon on the performance and learning of a dynamic force-production task. The after-contraction effect refers to an involuntary potentiation (induced by a sustained pre-contraction) that is thought to summate with voluntary motor commands to bias subsequent responding. The precontraction involved a brief (20 s) static contraction. The subsequent influence of the precontraction on a dynamic force-production task was assessed. Experiments 1 and 2 were aimed at demonstrating the direct impact of the precontraction intensity on the magnitude and decay of the after-contraction effect. The results indicated that as the intensity of the precontraction increased, the magnitude of the induced bias increased. In Experiment 3, the indirect influence on subsequent retention of varying the precontraction intensity during acquisition was investigated. The results indicated that the performance of subjects experiencing varying precontraction intensities during acquisition was inferior to that of subjects experiencing a constant precontraction intensity, but the performance of the varied precontraction intensities group was superior on the test of retention. It is noted that the paradoxical reversal from acquisition to retention is similar to that found in contextual interference experiments and may arise from similar mechanisms.     

Emotion-Focused Therapy for Couples in the Treatment of Depression: A Pilot Study

Emotion-focused therapy (EFT) for couples was compared to pharmacotherapy in the treatment of major depressive disorder. Eighteen distressed couples in which the female partner met diagnostic criteria for major depressive disorder were randomly assigned to 16 weekly sessions of emotion-focused therapy or pharmacotherapy with desipramine, trimipramine, or trazadone. Twelve couples completed the study. Both interventions were equally effective in symptom reduction. There was some evidence that females receiving EFT made greater improvement after the conclusion of treatment than those receiving pharmacotherapy. The results suggest EFT might be useful in the treatment of comorbid major depressive disorder and relational distress.     

Goal‐Proximity Decision‐Making

Reinforcement learning (RL) models of decision‐making cannot account for human decisions in the absence of prior reward or punishment. We propose a mechanism for choosing among available options based on goal‐option association strengths, where association strengths between objects represent previously experienced object proximity. The proposed mechanism, Goal‐Proximity Decision‐making (GPD), is implemented within the ACT‐R cognitive framework. GPD is found to be more efficient than RL in three maze‐navigation simulations. GPD advantages over RL seem to grow as task difficulty is increased. An experiment is presented where participants are asked to make choices in the absence of prior reward. GPD captures human performance in this experiment better than RL.     

Convergence and Its Limits: Relations Between Analytic and Continental Philosophy

Abstract

In this article, it is argued that a convergence between the (post-)analytic and continental traditions in philosophy is unlikely. Both traditions have fundamentally different approaches to questions concerning consciousness and subjectivity. They also differ in their conception of the role of philosophy, if we are to become autonomous and reflective humans beings.To illustrate this, a comparison is made between the work of the continental philosopher Dieter Henrich and the ‘post-analytic’ philosopher Thomas Nagel, who is often seen as a typical ‘converger‘.     

The Role of Psychological Climate in Neutralizing the Effects of Organizational Politics on Work Outcomes

The present study examined the moderating impact of psychological climate on the relationship between perceived organizational politics and both commitment and turnover intent. Data were gathered from 131 restaurant employees who completed surveys at work. Confirmatory factor analysis revealed that a 6-factor conceptualization (supportive management, role clarity, contribution, recognition, self-expression, and challenge) provided the most adequate model representation of the psychological climate construct. Results indicate that politics perceptions interacted with each climate factor (with the exception of challenge) in predicting commitment. Conversely, politics perceptions interacted only with supportive management and self-expression to predict turnover intent. Implications for theoretical development and empirical research in this domain are provided.
