The Parallel Episodic Processing (PEP) model: Dissociating contingency and conflict adaptation in the item-specific proportion congruent paradigm

The present work introduces a computational model, the Parallel Episodic Processing (PEP) model, which demonstrates that contingency learning achieved via simple storage and retrieval of episodic memories can explain the item-specific proportion congruency effect in the colour-word Stroop paradigm. The current work also presents a new experimental procedure to more directly dissociate contingency biases from conflict adaptation (i.e., proportion congruency). This was done with three different types of incongruent words that allow a comparison of: (a) high versus low contingency while keeping proportion congruency constant, and (b) high versus low proportion congruency while keeping contingency constant. Results demonstrated a significant contingency effect, but no effect of proportion congruence. It was further shown that the proportion congruency associated with the colour does not matter, either. Thus, the results quite directly demonstrate that ISPC effects are not due to conflict adaptation, but instead to contingency learning biases.     

Mentor status,occupational context,and protégé career outcomes: Differential returns for males and females

We report two studies examining the moderating effects of mentor status and protégé gender, along with the moderating role of occupational context, in the relationship of mentoring with protégé career outcomes. Our research replicates and extends previous findings, especially those by Ramaswami et al. (2010b). Results from Study 1 indicated that business school alumni with senior-male mentors earned more compensation than those with no mentors. Additionally, a 3-way interaction (protégé gender × senior-male mentor × occupation type) indicated that the senior-male mentor effect for compensation was especially prominent for females in male-gendered occupation types. Study 2, conducted in an aerospace manufacturing firm comprising both a male-gendered occupation and industry context, confirmed mentor-status by protégé gender interaction for compensation. Female protégés with senior mentors received more compensation than females with no mentors, and also more compensation than males with senior mentors. In contrast, protégés with “other” (not senior) mentors received less compensation than those with no mentors, with this negative effect being especially strong for females. Taken as a whole, these results confirm the importance of mentor status for protégé career success. The results also underscore the importance of considering both mentor attributes and work context in understanding male and female protégés' career returns from mentoring.     

Reliabilism and deflationism

In this article I examine several issues concerning reliabilism and deflationism. I critique Alvin Goldman's account of the key differences between correspondence and deflationary theories and his claim that reliabilism can be combined only with those truth theories that maintain a commitment to truthmakers. I then consider how reliability could be analysed from a deflationary perspective and show that deflationism is compatible with reliabilism. I close with a discussion of whether a deflationary theory of knowledge is possible.     

Anxiety Sensitivity and Interoceptive Exposure: A Transdiagnostic Construct and Change Strategy

Recent findings support the relevance of anxiety sensitivity (AS) and interoceptive exposure (IE) across emotional disorders. This study (a) evaluated levels of AS across different anxiety disorders, (b) examined change in AS over the course of transdiagnostic psychological intervention, and its relationship with outcome, and (c) described the implementation of IE to address AS with patients with different anxiety disorders. Participants (N = 54) were patients who received treatment with the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP) in two consecutive treatment trials. Participants completed a measure of AS at pre- and posttreatment, and multiple occasions during treatment. Symptom severity was assessed at pre- and posttreatment, and clinical information related to physical symptoms and IE were collected as part of routine clinical practice. Elevated AS was observed at pretreatment across diagnoses and decreases in AS were observed from pre- to posttreatment. Similar changes occurred across the diagnostic categories, notably coinciding with the introduction of IE. Change in AS was correlated with reduced symptom levels at posttreatment and 6-month follow-up. Patients with different anxiety disorders endorsed similar physical symptoms and practiced similar IE exercises with similar effects. Results provide preliminary support for the usefulness of IE as a treatment strategy across the spectrum of anxiety disorders, and additional support for the transdiagnostic relevance of AS.     

Zen Buddhism and the intrinsic value of nature

Part IIt is a perennial theme in the literature on environmental ethics that the exploitation of the environment is the result of a blindness to (or perhaps a refusal to recognize) the intrinsic value of natural beings. The general story here is that Western traditions of thought have tended to accord natural beings value only to the extent that they prove useful to humans, that they have tended to see nature as only instrumentally valuable. By contrast, it is said that a new, environmentally friendly understanding of the world would value nature ‘for its own sake’, would conceive natural beings as having intrinsic value. In the light of such an understanding, the oak tree, for instance, would be seen not merely as a source of timber or shade or as a decoration for the front lawn, but as valuable ‘in itself’, as having an intrinsic value that ought to be respected (see further, O'Neill 1993, chapter 2).     

Transformational leadership and task cohesion in sport: The mediating role of intrateam communication

ObjectivesLittle is known about the mechanisms that might mediate the relationship between transformational leadership behaviors and follower outcomes in the sporting domain. The purpose of this study was to examine whether intrateam communication mediated the effects of transformational leadership behaviors on task cohesion.Design/MethodsA cross-sectional study of university level ultimate frisbee players (N = 199). Participants completed a measure assessing their perceptions of their captain's transformational leadership behaviors. Post-competition, participants completed measures assessing perceptions of intrateam communication and task cohesion within their own team.ResultsMultilevel analyses revealed intrateam communication to partially mediate the relationships between two of the transformational leadership behaviors and task cohesion.ConclusionsIntrateam communication is seen to be a mechanism that explains the relationship between transformational leadership and task cohesion. Overall, the results support and add to the range of positive effects associated with transformational leadership in sport, and are suggestive of interventions that may raise levels of team cohesion.     

An adolescent perspective on injury recovery and the return to sport

ObjectivesThe purpose of this investigation was to examine adolescent athletes' injury recovery and return-to-sport experiences. Given previous research highlighting competence, autonomy, and relatedness concerns among returning athletes (Podlog & Eklund, 2006), we sought to examine the extent to which basic psychological needs theory (BPNT: Ryan & Deci, 2007) could be used as framework for interpreting the research findings.DesignA qualitative design was employed in the present investigation.MethodEleven Australian athletes (M age = 15.3) who had incurred a range of severe injuries (e.g., anterior cruciate ligament tears, shoulder dislocations) were interviewed on 2–3 occasions (n = 27 interviews) spanning an 11-month period.ResultsAnalysis of the data revealed the following four key themes: (a) injury stress, (b) coping strategies, (c) experiences with social support, and (d) recovery outcomes. Injury stress provides insights into a range of stressors and strain responses reported by the adolescents across the recovery phases, while the theme on coping highlights the specific strategies used to maintain motivation, reduce uncertainties associated with the injury experience, and to keep focused on future athletic attainment. The third theme, experiences with social support, considers the transactions the adolescents held with members of their social network throughout their recovery. The final theme, recovery outcomes, describes participant perceptions of a successful/unsuccessful recovery and stress-related growth.ConclusionsResults suggest that competence and relatedness issues highlighted in BPNT may be relevant in exploring adolescent athletes' injury experience. Somewhat less evidence for the autonomy dimension of BPNT was apparent in adolescent comments.     

A non-linear model of dynamics: A case of panic

This is a case report of a patient with panic who is on the edge of relapse into alcoholism. It is a case of general theoretical interest, because of the separate phases of containment of his desperation, involving psychopharmacology, sociotherapy, and psychotherapy. It extends the dynamic model into non-linear dynamics, an extension that allows the patient to come to face his amazement at the sudden eruption of unconscious forces, and that allows the psychotherapist to see the therapeutic path of backing up from walking forward, unwittingly, into catastrophe.
