Women entering male-dominated fields often find themselves the only women present, i.e., they experience solo status. Solo status diminishes women’s performance when women are negatively stereotyped in the testing domain (Inzlicht & Ben-Zeev, 2000) or when the performance is public (Sekaquaptewa & Thompson, 2002). Because women experience greater body image concerns than men and underperform when these concerns are high (Fredrickson, Roberts, Noll, Quinn, & Twenge, 1998), body image concerns may also cause diminished performance in solo women. Women were given a stigmatized (i.e., heavy) or neutral appearance (via a manipulated photograph), then tested as either solos or non-solos. Results showed that women performed more poorly when given a stigmatized appearance and placed under solo status compared to when only one of these factors were present. Social identity threat concerns (Steele, Spencer, & Aronson, 2002) mediated the solo status effect on performance for women given a stigmatized appearance.  相似文献

This study was designed to examine whether radio format and musical artists' gender predict sexual content in trade advertisements geared toward radio program directors. Advertisements were coded from one of the leading music trade magazines, Radio & Records magazine, between 2002 and 2003. Results indicated that overall women artists used sexual content in trade advertisements more often and to a greater degree than did men. In some cases, advertisements in radio formats with younger demographic markets, such as pop or hip-hop, also used higher levels of sexual content. It is concluded that the organizational context of the commercial music industry helps to perpetuate status differences between women and men artists, which may then bring about a cognitive bias in the field that promotes women artists' over reliance on using sexual content in trade advertisements.  相似文献

This study describes an extension of Kazdin's work on acceptability of behavior therapy methods to the assessment of acceptability in the developing field of behavioral staff management. An instrument for assessing acceptability of behavioral staff management techniques was developed and then used to assess staff evaluations of four techniques that have been researched in the staff management literature (instruction, reinforcement, punishment, self-management). The effects on acceptability of problem difficulty and duration of supervisor-staff interaction were also investigated. Staff identified the techniques as having differing degrees of acceptability, with instruction rated most acceptable, followed in order by self-management, reinforcement, and punishment. Ancillary studies supported the reliability and validity of the scale. Results are placed within the context of a recent behavioral supervision model, and discussed in terms of social validity and consumer satisfaction issues. Implications for delivering behavioral staff management interventions are presented.  相似文献

A computer simulation of children’s arithmetic word-problem solving   总被引:1,自引:0,他引:1  
ARITHPRO is a computer simulation of children’s arithmetic word-problem solving behavior. It is an instantiation of a recently proposed cognitive model of the knowledge and procedures required to solve such problems. The program solves word problems by (1) comprehending the story text in which the problem is embedded, (2) comprehending numerical information as sets of objects, (3) building superstructures from these sets, thereby specifying their logical relations, and (4) using a counting procedure to derive the answer to the problem. This report describes ARITHPRO and its architecture and knowledge base. A few comparisons of ARITHPRO’s performance with that of children are also provided.  相似文献

Reductions in dietary fat have been recommended in the prevention of coronary heart disease. Because entrees contribute substantially to total meal fat content, we evaluated a cafeteria-based intervention for increasing the purchase rate of low-fat entrees (M = 6.83 g) relative to nonlowfat entrees (M = 25.59 g). The intervention included a poster listing the benefits of a LF diet and the daily LF entrees (i.e., broiled or baked chicken and fish dishes). During 6 days per phase, food selections (N = 3,264) were monitored by trained observers. The intervention, which cost $80.00, produced significant increases (i.e., from 20% to 35%) in the purchase rate of LF entrees.  相似文献

Word problems are notoriously difficult to solve. We suggest that much of the difficulty children experience with word problems can be attributed to difficulty in comprehending abstract or ambiguous language. We tested this hypothesis by (1) requiring children to recall problems either before or after solving them, (2) requiring them to generate final questions to incomplete word problems, and (3) modeling performance patterns using a computer simulation. Solution performance was found to be systematically related to recall and question generation performance. Correct solutions were associated with accurate recall of the problem structure and with appropriate question generation. Solution “errors” were found to be correct solutions to miscomprehended problems. Word problems that contained abstract or ambiguous language tended to be miscomprehended more often than those using simpler language, and there was a great deal of systematicity in the way these problems were miscomprehended. Solution error patterns were successfully simulated by manipulating a computer model's language comprehension strategies, as opposed to its knowledge of logical set relations.  相似文献

Psychosocial risk and resistance factors within the domains of parental functioning, family Stressors, and family resources were examined as predictors of psychological adjustment and physical problems in juvenile rheumatic disease patients (N=93), their healthy siblings (N=72), and demographically matched healthy controls (N=93). Family socioeconomic status and background variables showed few consistent relationships with child functioning. However, a constellation of risk and resistance factors tended to show comparable associations with functioning for patients, siblings, and controls. Higher parental depression and medical symptoms and more family Stressors, sibling problems, and burden of illness on the family predicted more problems among the patients. These relationships held when disease duration and severity were controlled. For the siblings, increased parental and patient dysfunction, more family Stressors, and less family cohesion and expressiveness were associated with more problems. Although the associations were not as strong, mothers' depression and lack of family cohesion and expressiveness also were related to more adjustment problems among the control children. These findings imply that there may be a general association between certain risk and resistance factors and childhood adaptation.This research was supported in part by NIH Multipurpose Arthritis Center Grant AM20610, NIMH Grant MH16744, and Veterans Administration Medical and Health Services Research and Development Service Research funds. Jan Gottlieb provided valuable help in all phases of the research. We appreciate the help of the staff of the Pediatric Rheumatology Clinic at Children's Hospital at Stanford and the families who participated in this study.  相似文献

Deontic reasoning is reasoning about what one may, ought, or ought not do in a given set of circumstances. Virtually all of our social institutions and child-rearing practices presume the capacity to reason about deontic concepts, such as what is permitted, obligated, or prohibited. Despite this, very little is known about the development of deontic reasoning. Two experiments were conducted that contrasted children’s reasoning performance on deontic and indicative reasoning tasks (i.e., the reduced array selection version of the Wason card selection task). Like adults, children as young as 3 years of age were found to adopt a violation-detecting strategy more often when reasoning about the deontic case than when reasoning about the indicative case. These results indicate that violation detection emerges as an effective deontic reasoning very early in human development.  相似文献
