Does the Need for Role Clarity Moderate the Relationship between Role Ambiguity and Athlete Satisfaction?

The purpose of the present study was to investigate the need for role clarity as a potential moderator of the role ambiguity–satisfaction relationship among interdependent sport athletes. Competitive “Junior B” ice hockey players (N = 112) representing eight teams completed the Role Ambiguity Scale, five subscales of the Athlete Satisfaction Questionnaire, and a measure of need for role clarity at approximately the mid-point of their competitive season. Correlational findings indicated that greater role ambiguity was associated with lower athlete satisfaction. However, consistent with the moderator hypothesis, the relationships between role ambiguity and various manifestations of satisfaction were only evident for those athletes who had a higher need for role clarity. Implications of the results are discussed and several avenues for application and future research are suggested.     

The moral significance of the material culture

Ethics as a philosophical discipline has always been preoccupied with theory to the detriment of practice and the exclusion of material culture. Lately, practice has been rehabilitated, but material culture continues to be ignored. Cultural critics and sociologists have attended to it but have also refrained from a moral assessment of it. The findings of Csikszentmihalyi and Rochberg‐Halton, however, reflect two kinds of cultural realities that sponsor two kinds of conduct. The first kind, represented by musical instruments, I call commanding reality. It invites social and physical engagement and provides orientation within the world. The second kind, exemplified by stereos, consists of consumable commodities and conduces to a life of distraction and disorientation. I conclude that ethics is not just a matter of conduct within whatever reality but of deciding which kind of reality we favor over the other. My plea is on behalf of commanding reality.

Modern philosophy has been at two removes from the real world. First, in aspiring to theory, it has been distanced from practice. Theory can inform practice, but practice is richer than theory and, above all, self‐sustaining. Practice can survive without theory while theory arises from a practice and perishes without the nourishment of a practice. Practice, as philosophers have always seen it, is in turn removed from its tangible setting. Yet material culture constrains and details practice decisively. Practice, abstracted from its tangible circumstances, is reduced to gesturing and sometimes to posturing.     

Theory,practice, reality

‘Disclosing New Worlds’ represents an extraordinarily fruitful response to the radically changed social and intellectual conditions of the late twentieth century. Its focus on skillful practice yields a social theory thicker than most. Yet in remaining aloof of material reality it retains an ambiguity that contemporary culture prevailingly resolves into a style of life largely devoid of skill and excellence. Consideration of material reality, however, discloses hopeful if inconspicuous practices as well, practices that are at the center of the good life and constitute the wellspring of solidarity. University teaching can be a vigorous introduction to that sort of life.     

The Effect of Fatigue on Learning and Performance of a Gross Motor Task

40 college males were sequentially assigned to 1 of 2 groups to examine the effects of induced physical fatigue upon the performance and learning of a gross motor task, the stabilometer. All Ss were given 32 practice trials over 3 practice sessions, with 48 hr. rest interpolated between sessions. Trials 1 and 2 were performed under control conditions (no fatigue) for both groups. The Experimental Group was then required to perform under conditions of physical fatigue during Trials 3-26. Trials 27-32 (Session 3) were performed under control conditions. The condition of fatigue was achieved on Trials 3-26 by having Ss pedal a bicycle ergometer until a heart rate of 180 beats/min was attained prior to each trial. The Control Group cancelled vowels. The results indicated that physical fatigue was detrimental to the performance and learning of the Experimental Group.     

Psychometric Properties and Norms for the Personality Assessment Inventory in Egg Donors and Gestational Carriers

Although psychological evaluations are an integral element of screening for third-party reproduction and the Personality Assessment Inventory (PAI) is commonly used for these evaluations, little is known about the psychometric properties or normative scores on the PAI among egg donors and carriers. We evaluated the PAI among 1,044 egg donors and gestational carriers from various fertility clinics across the United States. PAI scales were generally internally consistent in this population, although range restriction appeared to attenuate reliability on several scales. The PAI profiles of egg donors and carriers had elevated positive impression management and suppressed clinical scale scores relative to the community standardization sample, as would be expected given the contingencies of this assessment context. Scores were similar across egg donors and carriers and were similar whether the carrier or donor was known or not known to the prospective parents. Sample-specific norms are provided for the use of the PAI in this setting.     

Attitudes Toward Voluntary and Involuntary Childlessness

Prior research has documented negative attitudes toward the voluntarily childless. Although research indicates that infertile couples perceive their condition to be discrediting, the extent to which the public considers involuntary childlessness as a negative attribute is unclear. Infertility might be construed by many to be a disease of professional couples overly concerned with careers or too stressed to conceive. In this experiment, 215 university students read one of six scenarios describing a couple as either: (a) voluntarily childless, involuntarily childless, or having children; or (b) holding professional or nonprofessional employment. Subjects rated each member of the couple on 26 characteristics (e.g., ambitious, caring, and stressed) and responded to 12 items concerning the quality and strength of the couple's relationship. Results support prior research demonstrating a stigma of voluntary childlessness but suggest that involuntary childlessness is not universally stigmatizing and may actually lead to some positive attributions. Recommendations for future research and applications are discussed.     

Sensory substitution: an approach to the experimental study of perception / Sustitución sensorial: un abordaje para el estudio experimental de la percepción

Abstract

Sensory substitution refers to the phenomenon where object and environment information normally acquired through one sense can be obtained by another sense. For example, visual input being provided by hearing or touching. Sensory substitution devices are technological designs that transform the characteristics of one sensory modality into stimuli of another sensory modality. These devices were developed with two purposes: (1) to assist people with sensory disabilities in daily tasks; and (2) to study the involved mechanisms of brain plasticity. This article reviews studies in which sensory substitution phenomenon is employed as a methodological strategy to study visual perception. Furthermore, its use is discussed as an experimental platform to contrast new perceptual theories and underlying neurophysiological mechanisms that are currently under review.
