Social contagion of binge eating

A social psychological account of the acquisition of binge eating, analogous to the classic social psychological work, "Social Pressures in Informal Groups" (Festinger, Schachter, & Back, 1950), is suggested and tested in two college sororities. In these sororities, clear evidence of group norms about appropriate binge-eating behavior was found; in one sorority, the more one binged, the more popular one was. In the other, popularity was associated with binging the right amount: Those who binged too much or too little were less popular than those who binged at the mean. Evidence of social pressures to binge eat were found as well. By the end of the academic year, a sorority member's binge eating could be predicted from the binge-eating level of her friends (average r = .31). As friendship groups grew more cohesive, a sorority member's binge eating grew more and more like that of her friends (average r = .35). The parsimony of a social psychological account of the acquisition of binge eating behavior is shown. I argue that there is no great mystery to how bulimia has become such a serious problem for today's women. Binge eating seems to be an acquired pattern of behavior, perhaps through modeling, and appears to be learned much like any other set of behaviors. Like other behaviors, it is under substantial social control.     

Central auditory processing : III. The “cocktail party” effect and anterior temporal lobectomy

The capacity to selectively attend to only one of multiple, spatially separated, simultaneous sound sources—the “cocktail party” effect—was evaluated in normal subjects and in those with anterior temporal lobectomy using common environmental sounds. A significant deficit in this capacity was observed for those stimuli located on the side of space contralateral to the lobectomy, a finding consistent with the hypothesis that within each anterior temporal lobe is a mechanism that is normally capable of enhancing the perceptual salience of one acoustic stimulus on the opposite side of space, when other sound sources are present on that side. Damage to this mechanism also appears to be associated with a deficit of spatial localization for sounds contralateral to the lesion.     

An Evaluation of the Jamaican Anticrime Program

A sweeping anticrime package was implemented in Jamaica in 1974. This program included severe penalties for possession of illegal guns, censorhsip of gun scenes from television and the movies, and greatly broadened police powers. The impact of this anticrime package on crime was assessed using quasiexperimental time-series designs with both months and years as the units of analysis. In a one year period there was a 14% reduction in homicides ( p <.05), a 32% reduction in rapes ( p <.01), a 25% reduction in robberies ( p <.05), and a 37% reduction in nonfatal shootings ( p <.01). Data from the second year following the implementation of the anticrime package were not available. The data from the fist year suggest that strict anticrime measures can reduce crime.     

Gender Differences in the Social Functioning of Adolescents with Inflammatory Bowel Disease

Inflammatory bowel disease (IBD) has been associated with social difficulties. Boys with IBD may have increased risk for social problems due to delayed growth and puberty, but gender differences in social functioning have not been investigated. This study examined gender differences in multiple areas of social functioning for adolescents with IBD compared to healthy adolescents. Participants were 92 adolescents 11-17?years (50 with IBD, 42 healthy) and parents who completed questionnaires assessing social functioning. IBD was associated with poorer social functioning in the areas of social competence and social problems. Boys with IBD had worse social competence, with no gender differences for social problems. Gender predicted the use of social contact as a coping strategy, but no significant group differences were found for other areas of social functioning. Adolescents with IBD experience significant social difficulties in some areas, and boys are at risk for poor social competence. However, previously reported social difficulties may not extend to all areas of social functioning.     

Stereotype Threat in Applied Settings Re-Examined

Stricker & Ward (2004 ) examined stereotype threat with a national sample of students taking an Advanced Placement (AP) Calculus exam, and a smaller sample taking Computerized Placement Tests (CPT). They inquired about gender either before (traditional) or after the test (which can reduce stereotype threat). They reported no significant effects of question timing. We reanalyze their findings, and argue that their conservative criterion for evidence led them to overlook significant stereotype threat effects with real practical implications. Women benefited substantially on the Calculus test, and on the CPT–Reading when demographics were asked after testing rather than before. This simple, small, and inexpensive change could increase U.S. women receiving AP Calculus AB credit by more than 4,700 every year.     

Stereotypes and implicit social comparison: Shifts in comparison-group focus

Stereotypes affect how people understand implicit comparisons. In two studies, people judged the comparison implied by a statement (e.g., “Math is easy for me,” “I’m really aggressive”) made by an African-American, White, or Asian-American male. Counter-stereotypic comments, such as the African-American saying he was “bad” at basketball, caused participants to think the target was comparing himself to his narrow ingroup; stereotypic statements caused people to infer that the comparison group was broader. When compared to a fixed standard (all people in USA), evidence that people used stereotypes consistently emerged. Whether motivated or not, by narrowing the comparison standard when presented with a counter-stereotypic case, participants constructed an understanding of the target that protected the stereotype from challenge.     

Professional preparation of individuals who provide genetic counseling services

An unprecedented increase has occurred in demand for genetic counseling services during the current decade. This study examined the complex issue of who currently provides genetic counseling services and the professional preparation of these personnel. A self-administered questionnaire was mailed to 325 genetic counseling professionals in the southeastern United States who were members of the Southeast Regional Genetics Group (SERGG), National Society of Genetic Counselors, or American Society of Human Genetics States; 204 completed the questionnaire (63%). Seventy percent of respondents were female and 30% were male. Thirty percent of respondents held MD degrees; nine physicians held PhD degrees. Most physicians were male. Thirty-two percent of respondents held master's degrees in genetic counseling; five counselors held PhD degrees. Twenty-three percent of respondents were nurses; eight nurses held master's degrees. Three percent of respondents were social workers. Individuals with other degrees, such as an associate of science in medical technology and a doctoral degree in education, also provided genetic counseling. Genetic counseling typically involved a team effort, consisting mainly of physicians and genetic counselors. Most respondents reported college coursework in human genetics, supervised training, and seminar/workshop training. Thirty percent reported college coursework in counseling techniques, supervised training, and seminar/workshop training. Policy recommendations are offered concerning professional preparation of genetic counselors.
