In two experiments, conducted in Germany and the U.S.A., it was found that exposure to a rape report lowered self-esteem and positive affect in women who do not accept ‘rape myths’ (stereotypical beliefs which blame the victim and exonerate the rapist; Burt, 1980). Men high in rape myth acceptance (RMA) showed an increase in positive affect and self-esteem as a function of exposure to rape; men low in RMA and women high in RMA were largely unaffected. Both experiments demonstrated that these effects were specific to rape, as opposed to violence in general. These results support the feminist hypothesis that the threat of rape serves the function to exert social control over women and to sustain men's dominance. Potential cognitive mechanisms mediating the observed effects are discussed. 相似文献

Many “higher” animals are commonly assumed to distinguish between individual humans. This belief is based largely on anecdotal reports; in reality, there is little empirical evidence to support human recognition in nonhuman species. We report that laboratory rats consistently chose a familiar human over an unfamiliar human following fourteen and five 10-min exposures and even following a single 10-min exposure. Furthermore, this preference was retained in the absence of additional contact for at least 5 months. These results confirm that laboratory rats can tell individual humans apart, a prerequisite for associating them with hedonic events. Such human-based conditioning, described by Pavlov and by Gantt, Newton, Royer, and Stephens (1966), may have important implications for animal research in a variety of settings. 相似文献

THE EFFECTS OF CHOICE AND TASK PREFERENCE ON THE WORK PERFORMANCE OF ADULTS WITH SEVERE DISABILITIES
Linda M. Bambara Christina Ager Freya Koger 《Journal of applied behavior analysis》1994,27(3):555-556
We evaluated the effects of choice versus the assignment of tasks of varying preferences on the work engagement of adults with severe disabilities. The combined results of two experiments suggest that the relative preference for a task may be an important variable in the effectiveness of choice for some individuals. 相似文献

Previous experiments have shown that the procedure of questioning subjects retrospectively about the input and output status of information (input and output monitoring) is a useful method for assessing the awareness states of subjects during implicit and explicit memory tasks. The main purpose of the present study was to investigate whether the previous findings could be extended to other implicit and explicit memory tasks. We were especially interested in whether differences in input- and output-monitoring performance can be observed when both the implicit and explicit memory tasks are conceptual ones. In a final test phase, the target items from the study phase and new distractor items were presented. In a recognition-like situation, subjects had to decide whether an item had been presented in the study phase (input status), as well as whether they had produced the item in the memory-test phase (output status). In all three experiments judgments about the input status - but only for those items that had been produced in the implicit or in the explicit memory test - were more precise after explicit than after implicit memory testings. This finding was not influenced by the distinction between perceptual and conceptual-memory tasks (Exp. 1), and was obtained under conditions in which the implicit and the explicit memory tasks were both conceptual and differed only in test instructions (Exps. 2 and 3). These results suggest that not only subjects performing a perceptual test of implicit memory, but also subjects in a conceptual implicit test were less aware of using information from a previous study episode than subjects who received memory instructions. It is concluded that requiring judgments about the input status of information is a good method for assessing subjects test awareness and is preferable to the use of a questionnaire (Exp. 3). In contrast, in all three experiments no differences were found with the output-monitoring measure between implicit and explicit test conditions. 相似文献

A mother's (prenatal) wish for a girl has, at times, been implicated as an etiological factor for boyhood femininity or its DSM-III-R diagnostic equivalent, the Gender Identity Disorder of Childhood. In one sample of 52 feminine and 52 nonclinical control boys from Los Angeles, the proportion of mothers who recalled a wish for a girl during the pregnancy did not differ significantly between groups (26.9% vs. 19.2%, respectively); however, in both groups, the maternal wish for a girl was significantly more common in sibships in which all of the proband's older siblings were male. In a second sample of 103 feminine boys from Toronto, the maternal wish for a girl was significantly higher than that found in the Los Angeles sample (43.7% vs. 26.9%), but a control group was not available; as in the Los Angeles sample, the maternal wish for a girl was significantly more common in sibships in which all of the proband's older siblings were male. Implications of these findings for further study of maternal influences on boyhood femininity are discussed. 相似文献

It is argued that existing axiomatic theories of utility do not provide the utility principle or the principle of maximising expected utility with a formal justification. It is also argued that these theories only put mild constraints on a decision-maker in a decision-context. Finally, it is argued that the prospects are not particularly bright for finding formal non-circular arguments for the utility principle that do not rely on the law of large numbers. 相似文献

Five experiments reexamined color aftereffects contingent on the semantic properties of text (Allan, Siegel, Collins, & MacQueen, 1989). The influence of different assessment techniques and the effect of eye movements and overlapping contour information on the induction of color aftereffects by word and nonword letter strings were determined. Experiment 1 showed that no aftereffect was found when a traditional method of assessing color aftereffects was used. Experiments 2 and 4 demonstrated color aftereffects forboth words and nonwords, but only when subjects fixated the same locus during induction and testing and only when assessed with the technique described by Allan et al. (1989). If, however, eye movements were made during induction, no color aftereffect was obtained (Experiment 3). Induction to nontext patterns with properties similar to those of text but with fewer overlapping contours resulted in a strong color aftereffect (Experiment 5). These results suggest that the color aftereffect contingent on text is very weak and is not dependent on semantic factors, but that it is a product of induction to local color and orientation information. 相似文献

A MEDIATIONAL MODEL OF AUTONOMY, SELF-ESTEEM, AND EATING DISORDERED ATTITUDES AND BEHAVIORS 总被引:1,自引:0,他引:1
This study expands upon existing literature by examining how the relationship between autonomy deficits and low self-esteem may create a psychological environment conducive to the development of eating disordered behaviors. Findings supported a mediational model to account for eating disordered behaviors in 71 college women. In this model, lack of autonomy was related to decreased global self-esteem, which in turn was associated with bulimia, body dissatisfaction, and drive for thinness. Although only tentative and cross-sectional in nature, this study is of particular importance because it links autonomy and self-esteem in a coherent model predictive of eating disordered behaviors in college women. Developmental aspects of eating disorders and treatment implications are discussed. 相似文献

Myths and stereotypes about sexual assault reflect a society which excuses perpetrators of assault and blames victims for failing to control men's sexuality. Such views are well-established by early adulthood, but there is little research with adolescents. This study surveyed two hundred forty-four 14–16 year old Australian high school students (105 male, 139 female), of Anglo-European descent. Males were significantly more likely to endorse sexual assault myths, to agree that forced sex was acceptable in some situations, and to hold false stereotypes about sexual assault. Males also held more restrictive attitudes toward women's roles and endorsed a greater level of sexism in dating relationships. This suggests that male and female adolescents have differing expectations of dating relationships, which may underlie sexual assault within relationships. Assault-supportive attitudes are apparent at a young age, supporting the need for educational and social interventions targeting young people. 相似文献
