Factors impacting emergence of behavioral control by underselected stimuli in humans after reduction of control by overselected stimuli

Stimulus overselectivity occurs when only one of potentially many aspects of the environment controls behavior. Adult participants were trained and tested on a trial-and-error discrimination learning task while engaging in a concurrent load task, and overselectivity emerged. When responding to the overselected stimulus was reduced by reinforcing a novel stimulus in the presence of the previously overselected stimulus in a second trial-and-error discrimination task, behavioral control by the underselected stimulus became stronger. However, this result was only found under certain circumstances: when there was substantial overselectivity in the first training phase; when control by the underselected stimulus in the first phase was particularly low; and when there was effective reduction in the behavioral control exerted by the previously overselected stimuli. The emergence of behavioral control by the underselected stimulus suggests that overselectivity is not simply due to an attention deficit, because for the emergence to occur, the stimuli must have been attended to and learned about in the training phase; but that a range of additional learning factors may play a role.     

Exploring Debriefing in Sports: A Qualitative Perspective

This study explored athletes’ and coaches’ experience of debriefing. Six coaches and 11 athletes (M age = 21.09, SD = 3.30) of different competitive levels and sports participated in semi-structured interviews. Participants’ experiences reflected that debriefing was generally employed for performance evaluation and learning purposes. Psychological benefits of debriefing were seen as a by-product rather than an aim of the process. The power differential in some coach-athlete relationships was identified as limiting debriefing efficacy. From an applied perspective, the results highlight the need to increase athletes’ active participation in the debriefing process and to improve coaches’ and athletes’ understanding of psychological recovery.     

Sureness Measures And Rating Extremity In Repertory Grid Technique: An Exploratory Study

Abstract

Twenty men and 20 women completed two Role Construct Repertory Tests (Kelly, 1955). One of the tests required subjects to assign elements (people known to the subject) to 12 bipolar constructs. The other test required subjects to rate the elements on scales defined by the constructs. For half of the scaled ratings, subjects were asked to record the degree to which they were sure of their decision using a scale ranging from 1 to 5. This measure of “sureness” was found to be related to familiarity to the element and extremity of the ratings. Women were more sure than men, and subjects were more sure of positive ratings than negative. The utility of the sureness measure is discussed and various interpretations of extremity and sureness are explored.     

Male/Male Sex in Hong Kong: Privacy,Please?

In August 2005, the age of consent for male/male sexual activity in Hong Kong was held to be arbitrarily and discriminatorily targeting gay men and thus in violation of an individual’s right to privacy and his right of equality on the basis of sexual orientation. While the decision has since been affirmed on appeal, it has been argued that judicial recourse to equality rights where privacy rights would have sufficed for the provisions to be struck down was a misguided, if not mistaken, effort that merely reinforced the stereotype that gay men are “hypersexualized” and was a setback for the gay rights movement in Hong Kong. This article examines whether the argument is a well-founded one and discusses the implications of confining a man’s right to have consensual sex with another man to his privacy rights alone.

Toward a Perspicuous Presentation of “Perspicuous Presentation”1

Gordon Baker in his last decade published a series of papers (now collected in Baker 2004 ), which are revolutionary in their proposals for understanding of later Wittgenstein. Taking our lead from the first of those papers, on “perspicuous presentations,” we offer new criticisms of ‘elucidatory’ readers of later Wittgenstein, such as Peter Hacker: we argue that their readings fail to connect with the radically therapeutic intent of the ‘perspicuous presentation’ concept, as an achievement‐term, rather than a kind of ‘objective’ mapping of a ‘conceptual landscape.’ Baker's Wittgenstein, far from being a ‘language policeman’ of the kind that often fails to influence mainstream philosophy, offers an alternative to the latent scientism of Wittgenstein's influential ‘elucidatory’ readers.     

Understanding intention from minimal displays of human activity

The impression of animacy from the motion of simple shapes typically relies on synthetically defined motion patterns resulting in pseudorepresentations of human movement. Thus, it is unclear how these synthetic motions relate to actual biological agents. To clarify this relationship, we introduce a novel approach that uses video processing to reduce full-video displays of human interactions to animacy displays, thus creating animate shapes whose motions are directly derived from human actions. Furthermore, this technique facilitates the comparison of interactions in animacy displays from different viewpoints-an area that has yet to be researched. We introduce two experiments in which animacy displays were created showing six dyadic interactions from two viewpoints, incorporating cues altering the quantity of the visual information available. With a six-alternative forced choice task, results indicate that animacy displays can be created via this naturalistic technique and reveal a previously unreported advantage for viewing intentional motion from an overhead viewpoint.     

Adoption Counselors' Perspectives of Counseling Postadoptive Families

This study was conducted to explore the mental health needs of families who adopted from the state welfare system. Using consensual qualitative research, the authors examined the perspectives of 8 clinical mental health counselors who provided counseling services to postadoptive families. Findings represented by 5 domains and supported by 15 categories include the counselors' perspective of (a) strength of the current program, (b) families in crisis, (c) parents' construction of their child's problem, (d) programmatic limitations, and (e) systemic limitations.
