This study examined gendered perceptions of relational and physical aggressive behaviors and personal experiences with both types of aggression. Prior research suggested that physical aggression by males and relational aggression by females would be perceived most negatively. College students (186 female, 128 male) rated the acceptability and harmfulness of aggression in scenarios in which type of aggression and perpetrator and target gender were varied. As predicted, relational aggression by female characters and physical aggression by male characters were rated as less acceptable and more aggressive/harmful than the same behavior by the other gender. Thus, expectations regarding the gender-appropriateness of aggression appear to affect perceptions of such acts. Despite popular conceptions that females use and are harmed by relational aggression more than males, there was no gender difference in experience with relational aggression, nor were female targets viewed as more harmed by such aggression than their male counterparts.  相似文献

The purpose of the present research was to investigate the relationship of the self-esteem of female athletes and nonathletes to sex role type and sport type. The athletic group was comprised of 75 female collegiate athletes from eight sports and the nonathletic group consisted of a random sample of 75 female nonathletes. An assessment of self-esteem and sex role type was completed through administering to all subjects the short form of the (PRF) ANDRO Scale of Masculinity and Femininity, and the Interpersonal Disposition Inventory (IDI). On the basis of the results of the IDI, the subjects were categorized into four sex role types: androgynous, masculine, feminine, and undifferentiated. Based upon previous research, it was predicted that (1) athletes would exhibit higher self-esteem scores than nonathletes, (2) the self-esteem of androgynous individuals would be higher than other sex role types, (3) the self-esteem of feminine or undifferentiated individuals would be lower than other sex role types, (4) the self-esteem of female athletes in higher femininity status sports would be greater than those in lower femininity status sports, and (5) there would be a greater proportion of androgynous athletes and feminine nonathletes. The following significant results were found: nonathletes in the feminine sex role type were lower in self-esteem than all other groups; and there was a greater proportion of androgynous athletes and feminine nonathletes than expected by chance. There were no differences in self-esteem of athletes in higher femininity status vs lower femininity status sports. These findings were discussed relative to past research, and the potential impact of sport on the psychosocial development or selection of certain sex role types.  相似文献

Previous work has shown that people seem less able to perceive sex discrimination on a personal level than on a societal level. The present experiment was performed to test the hypothesis that this phenomenon is in part an information-processing bias; that is, the perception of discrimination is more difficult when one makes case-by-case comparisons than when one encounters information in aggregate form. The experiment demonstrated the importance of formatting for the perception of discrimination. Among subjects with little or no emotional investment in the issue of sex discrimination, the format of the pertinent information has a large effect on information processing: subjects perceived less discrimination when they encountered the relevant information in little chunks than when they saw the total picture at a single shot.  相似文献

Two experiments investigated whether lexical complexity increases a word’s processing time. Subjects read sentences, each containing a target word, while their eye movements were monitored. In experiment 1, mean fixation time on infrequent words was longer than on their more frequent controls, as was the first fixation after the Infrequent Target. Fixation Times on Causative, factive, and negative verbs and ambiguous nouns were no longer than on their controls. Further analyses on the ambiguous nouns, however, suggested that the likelihood of their various meanings affected fixation time. This factor was investigated in experiment 2. subjects spent a longer time fixating ambiguous words with two equally likely meanings than fixating ambiguous words with one highly likely meaning. The results suggest that verb complexity does not affect lexical access time, and that word frequency And the presence of two highly likely meanings may affect lexical access and/or postaccess integration.  相似文献

Conclusions The model of ethnicity has been applied in this paper to Appalachian natives. The problems suffered by Appalachians in terms of high dropout rates, institutional discrimination, prejudice, and stereotyping are familiar to other ethnic minority groups. Yet because the majority of the population in Appalachia are racially indistinct from mainstream Americans, there is resistance to the notion of ethnic difference. This has significant repercussions. Ironically, service providers and others in the region often recognize the distinctive nature of native Appalachians while, at the same time, reaffirming that they are white Americans like anywhere else. This is often said with good intentions. The result, however, justifies a lack of action taken to improve services for native Appalachians. If they are perceived as no different, inequalities go unrecognized and unredressed. If, on the other hand, differences are perceived only on the basis of socioeconomic class and/or rural residence, social services may miss the cultural dimension that may be all-important in identifying problems and potential means of improvement. It is hoped that application of the notion of ethnicity to mountain people will be helpful in the structuring of human services in the region.I am indebted to Mae Reck and Gregory Reck who have greatly contributed to my thinking on Appalachian ethnicity. I also thank two graduate students, Mildred Dunevant and Stephanie Perrin, who read and commented on this paper.  相似文献

Forty-six parent-referred problem 3-year-olds and 22 comparison children were assessed with parent report and observational measures; 54 were followed up at age 4, and 53 were followed again at age 6. Lower social class and greater family stress were associated with higher symptom ratings at initial referral and age 6 follow-up. Negative and directive maternal behavior and negative and noncompliant child behavior observed in the lab at age 3 were associated with higher maternal ratings of child aggression and hyperactivity; these observed behaviors continued to be highly predictive of maternal ratings of persistent problems at ages 4 and 6. A laboratory index of inattention and overactivity at intake also predicted hyperactivity ratings at age 6. These findings suggest that externalizing problems identified in early childhood are likely to persist when they are associated with more family disruption and a negative mother-child relationship.This research was supported by Grant No. MH 32735 from the National Institute of Mental Health to Dr. Campbell. We are indebted to the children and families who have participated so enthusiastically in this study over the past 5 years. The help of Deborah Baldwin, Patricia Cluss, and Diane Gluck is gratefully acknowledged. Many additional people participated in various phases of this study as independent observers and data coders. Their contributions are also recognized.  相似文献
