The experiences of 44 group sexual assault victims (multiple offenders, one victim) were compared with 44 individual sexual assault victims (one offender, one victim). Sexual assaults included various degrees of sexual victimization ranging from verbal coercion to rape. Participants were located from among a national sample of 3,187 college women. Group sexual assaults, compared to individual sexual assaults, were in general more violent, involved greater resistance from the victims, and were more likely to be perpetrated by strangers or relatives and to involve an experience which met the legal definition of rape. Group sexual assaults were less likely to involve multiple episodes by the same offender(s). Group sexual assault victims were more likely than individual sexual assault victims to seek police and crisis services, to have contemplated suicide, and to have sought therapy postassault. Despite these differences, the two groups were similar in the amount of drinking and drug use during the assault and their scores on standardized measures of psychological symptoms.  相似文献

In this article, a theoretical distinction is proposed between representative outgroup minorities (representative of a minority category in the society, e.g. gays) and dissident outgroup minorities (defined as a minority subgroup within a larger outgroup category). Two studies are reported comparing the social influence of dissident outgroup minorities with that of ingroup minorities (belonging to the subject's own social category). It was predicted that a position advocated by a dissident outgroup minority would be more readily accepted than that of an ingroup minority, but that the ingroup minority would be more likely to elicit the generation of new, alternative solutions. A first experiment in which subjects were either exposed to an ingroup minority, an outgroup minority, or no influence source confirmed these predictions. In a second experiment, subjects were either exposed to a majority or to a minority source either belonging to the subject's own social category or to the outgroup. The results indicate that the position of an ingroup majority was readily accepted whereas the otherwise identical message of an outgroup majority was rejected; neither ingroup nor outgroup majority stimulated the development of alternative proposals. Again, in line with Nemeth' (1986a) theory, the position of an ingroup minority was rejected but stimulated the generation of new, alternative proposals. The differential role of social category membership in minority and majority influence and the applicability of Nemeth' (1986a) theory to the attitude change area are discussed.  相似文献

医学与文学的传统及创新   总被引:2,自引:0,他引:2  
论述医学与文学关系的文章习惯以阿波罗开头。文学与医学直到最近才成为医学人文学里的一个新的学术分支 ,但文学与医学的关系至少可追溯到古希腊。本文中 ,我将讨论如何看待医学与文学关系的四种传统方式 :其一 ,疾病的形象 (images) ,即文学中患病、苦难和死亡的主题 ;其二 ,治疗者的形象 ;其三 ,医生—诗人或医生—作家类型 ;其四 ,文学作为一种治疗方法。然后 ,我将简要讨论文学在今日医学教育中的作用并提供一个思辨性的结论。1 传统1 1 患病、苦难和死亡的主题与医学一样 ,文学关涉患病、苦难和死亡这些与人类同样古老的主题…  相似文献

How does the representation of boy and girl exemplars in curricular materials affect students’ learning? We tested two competing hypotheses about the impact of gender exemplar on learning: First, in line with Social Learning Theory, children might exhibit a same-gender bias such that they prefer to learn from exemplars that match their gender (H1). Second, consistent with research on children's stereotypes about gender and math (e.g., associating boys with math competence), children might prefer to learn from exemplars who match their stereotypes about who is good at math (H2). We tested these hypotheses with children in middle school (N = 166), a time of development in which stereotypes are well-engrained, but before gender differences in math achievement appear. Children viewed two distinct math strategies, each presented by a boy or girl exemplar. We then examined which strategy children employed on a subsequent math test as well as their perceived similarity to the exemplars and their awareness or endorsement of gender-math stereotypes. Children did not preferentially learn from same-gender exemplars. However, children with stereotypes associating boys with math were more likely to learn the more difficult strategy when it was presented by a boy exemplar than children who did not associate boys with math. The results of this study provide valuable insight into how children's stereotypes impact their real-world learning.  相似文献

The purpose of the present study was to test a self-determination theory model with the following hypotheses: (1) Patients’ autonomous causality personality orientation and oral health care professionals’ autonomy-supportive treatment styles, as perceived by patients, would both be positively indirectly associated with dental attendance through patients’ autonomous motivation for dental treatment. (2) Patients’ controlled causality personality orientation and oral health care professionals’ controlling treatment styles, as perceived by patients, would both be positively indirectly associated with avoidance of making a dental clinic appointment through patients’ anxiety for dental treatment. A sample size of about 200 patients was estimated to be acceptable in detecting moderate effect sizes (independent variables: 5–6; power: .80; p < .05). Student patients (N = 226) responded to a survey with validated questionnaires. Using LISREL, both hypotheses were supported. In addition, patients’ perception of a controlling treatment style moderated the controlled personality—dental anxiety relation, so that a lower controlling treatment style mitigated dental anxiety substantially among patients with a high control orientation. Effect sizes were moderate to large. Analyses (Z-scores) also revealed that the autonomous personality is more strongly linked to situational autonomous motivation than situational autonomy support, whereas a controlled personality and a perceived controlling treatment style are equally and significantly associated to dental anxiety. Both patient personalities and oral health care professionals’ treatment styles are substantially linked to autonomous motivation and anxiety for dental treatment, which are relatively strongly associated with dental attendance and avoiding dental clinic appointments, respectively.  相似文献
