Self-Objectification Among Physically Active Women

Objectification Theory (Fredrickson & Roberts, 1997) was used to examine (a) the mediation effects of body shame and flow on the relationship between self-objectification and disordered eating, (b) age differences in self-objectification, body shame, flow, and disordered eating, (c) the prediction of physical activity from self-objectification, flow, body shame, and disordered eating, and (d) the relationships between self-objectification, flow, and physical activity. Participants were 394 women ages 18–64. Results revealed that (a) body shame mediated the relationship between self-objectification and disordered eating, (b) younger women reported higher levels of self-objectification, body shame, dieting, and several flow characteristics, (c) older women scored higher on the loss of self-consciousness subscale of the flow measure, and (d) self-objectification was a significant predictor of physical activity.This article is based on the authors doctoral dissertation, which was completed at the University of North Carolina at Greensboro under the direction of Daniel Gould.     

The interpersonal circumplex as a model of interpersonal capabilities

In this study, we sought to challenge the existing conceptualization of interpersonal capabilities as a distinct construct from interpersonal traits by explicitly taking into account the general factor inherent within most models of circumplexes. A sample of 206 college students completed a battery of measures including the Battery of Interpersonal Capabilities (BIC; Paulhus & Martin, 1987). Principal components analysis and the randomization test of hypothesized order relations demonstrated that contrary to previous findings, the BIC adhered to a circular ordering. Joint analysis of the BIC with the Interpersonal Adjective Scale (Wiggins, 1995) using principal components analysis and structural equation modeling demonstrated that the 2 measures represented similar constructs. Furthermore, the general factor in the BIC was not correlated with measures of general self-competence, satisfaction with life, or general pathology.     

The reported prevalence of mandated community treatment in two Florida samples

Questions on multiple modes of mandated community treatment (e.g. outpatient commitment, advance directive, representative payee, and special housing) were included in two studies of persons with mental illness, using a mail survey of Medicaid enrollees receiving SSI and interviews conducted as part of an evaluation of a specialty mental health court. Results indicate that the majority of individuals reported no experience with any forms of mandated community treatment. However, respondents from the two samples who had been subject to community mandates reported comparatively similar experiences. Additional studies of the prevalence of mandated community treatment are necessary to garner expanded information regarding the use of such mandates. In addition, future studies must assure that the language employed to query individuals regarding such mandates is clearly understood by respondents, as certain terms (e.g. "outpatient commitment") may mean different things to different respondents.     

Cohesion and performance in groups: a meta-analytic clarification of construct relations

Previous meta-analytic examinations of group cohesion and performance have focused primarily on contextual factors. This study examined issues relevant to applied researchers by providing a more detailed analysis of the criterion domain. In addition, the authors reinvestigated the role of components of cohesion using more modern meta-analytic methods and in light of different types of performance criteria. The results of the authors' meta-analyses revealed stronger correlations between cohesion and performance when performance was defined as behavior (as opposed to outcome), when it was assessed with efficiency measures (as opposed to effectiveness measures), and as patterns of team workflow became more intensive. In addition, and in contrast to B. Mullen and C. Copper's (1994) meta-analysis, the 3 main components of cohesion were independently related to the various performance domains. Implications for organizations and future research on cohesion and performance are discussed.     

The ecology of eating: smaller portion sizes in France Than in the United States help explain the French paradox

Part of the "French paradox" can be explained by the fact that the French eat less than Americans. We document that French portion sizes are smaller in comparable restaurants, in the sizes of individual portions of foods (but not other items) in supermarkets, in portions specified in cookbooks, and in the prominence of "all you can eat" restaurants in dining guides. We also present data, from observations at McDonald's, that the French take longer to eat than Americans. Our results suggest that in the domain of eating, and more generally, more attention should be paid to ecological factors, even though their mechanism of operation is transparent, and hence less revealing of fundamental psychological processes. Ironically, although the French eat less than Americans, they seem to eat for a longer period of time, and hence have more food experience. The French can have their cake and eat it as well.     

Effects of Paired and Unpaired Eye-Blink Conditioning on Purkinje Cell Morphology

This experiment addressed (1) the importance of conjunctive stimulus presentation for morphological plasticity of cerebellar Purkinje cells and inhibitory interneurons and (2) whether plasticity is restricted to the spiny branches of Purkinje cells, which receive parallel fiber input. These issues were investigated in naive rabbits and in rabbits that received paired or unpaired presentations of the conditioned stimulus (CS) and unconditioned stimulus (US). To direct CS input to the cerebellar cortex, pontine stimulation served as the CS. Air puffs to the cornea served as the US. Paired condition rabbits received pontine stimulation for 350 msec paired with a coterminating 100-msec air puff. Unpaired condition rabbits received the same stimuli in a pseudorandom order at 1- to 32-sec intervals. Rabbits were trained for a mean of 12 days. Naive rabbits received no treatment. In Golgi-stained Purkinje neurons in lobule HVI, total dendritic length, main branch length, total spiny branch length, and number of spiny branch arbors were all greater in the naive group than in the paired and unpaired groups, which did not differ. No differences were found between the hemispheres ipsilateral and contralateral to the trained eye. The dendritic length and number of branches for inhibitory interneurons did not differ across groups. The Purkinje cell morphological changes detected with these methods do not appear to be uniquely related to the conjunctive activation of the CS and US in the paired condition.

Perceptions of Youth Obesity among Physical Educators

The purposes of this study were to examine (a) antifat attitudes among physical education teachers, (b) performance and ability expectations for normal and overweight youth, and (c) perceptions of the problem of youth obesity and the role of schools and physical education. Participants, 105 physical educators, completed a demographic and background questionnaire, the Antifat Attitudes Scale (AFAS; Morrison & O’Connor), an expectations questionnaire, and Perceptions of Youth Obesity and Physical Education Questionnaire (Price, Desmond, & Ruppert). Participants endorsed moderate antifat attitudes and strong personal weight control beliefs. Participants reported higher expectations for youth they considered normal weight, versus overweight, across a variety of performance and ability areas. Participants overwhelmingly agreed that youth obesity is a concern and that schools are not doing enough to help overweight youth.     

A Field-Tested Task Analysis for Creating Single-Subject Graphs Using Microsoft<Superscript>®</Superscript> Office Excel

Creating single-subject (SS) graphs is challenging for many researchers and practitioners because it is a complex task with many steps. Although several authors have introduced guidelines for creating SS graphs, many users continue to experience frustration. The purpose of this article is to minimize these frustrations by providing a field-tested task analysis for creating SS graphs using Microsoft^® Office Excel. Results from the field test are presented and the task analysis, which includes steps for creating a variety of SS graphs, is provided. The article includes various illustrations, a list of prerequisite skills, tips, and troubleshooting items.
