In this rejoinder to Tidwell and Corona Garrett (1994), the authors discuss three important aspects of the term at risk that help to clarify its meaning.  相似文献

Recent research in risk perception has examined the role of affect and worldviews as orienting dispositions that guide people's decisions about complex and risky topics such as nuclear energy. This study tests and supports the hypothesis that worldviews and affect-laden imagery are highly predictive of perceptions of risk from nuclear power and support for that technology. Furthermore, affect and worldviews each contribute independently to the prediction of nuclear support. We find also that a person's affective imagery associated with nuclear power is systematically related to their worldviews. We conclude that affect and worldviews appear to play similar roles as orienting mechanisms, helping people navigate in a complex, uncertain, and sometimes dangerous world. The implication of this view for the practice of risk communication is briefly discussed.  相似文献

The paper presents a test of an ecologically differentiated model of social network orientation for adolescents that distinguished between different social network reference groups (family, peers, and nonfamily adults). The model was tested in two consecutive studies. Study 1 describes initial model development (N = 120). Study 2 presents a confirmatory factor analysis with a second sample (N = 430) to replicate the factor structure developed in Study 1. Results supported a three-factor model of network orientation that differentiated between network reference groups. Analyses of concurrent and predictive validity indicated that orientation to network reference groups was differentially related to the perceived quality and frequency of support from members of respective social network groups. Group differences (gender, race) regarding network orientation to different network reference groups were consistent with studies of other social network processes. Implications for the study of the network orientation and the study of social networks more generally are discussed.  相似文献

In two experiments, the pattern of persistence of negative priming effects across delay intervals of 500 and 2,500 msec was assessed using a within-subjects, random sequencing of delays. Neill and Valdes (1992; Neill, Valdes, Terry, & Gorfein, 1992) have argued that a within-subject experimental design is required for decay of negative priming to be seen, in contrast to results reported elsewhere (e.g., Tipper, Weaver, Cameron, Brehaut, & Bastedo, 1991) showing stable negative priming effects across delays. In neither experiment was substantial evidence of decay detected, raising questions for the notion that suppression necessarily declines across brief temporal intervals and for the assertion that episodic retrieval is the sole source of negative priming.  相似文献

The purpose of the present study was to better understand the development of children's occupational knowledge, as assessed by their ability to give ratings to jobs along various dimensions that were similar to ratings given by adults, and to investigate differences in boys' and girls' ratings. Overall, younger students gave higher ratings to the jobs pictured than did older students. Also, females gave higher ratings to three of the four dimensions investigated. Girls rated traditionally female jobs higher on respect and service, while boys rated traditionally male jobs higher on respect and service. Both males and females agreed that more education would be required for the female jobs pictured, but that males would be paid more money for the male jobs pictured.  相似文献

Most women work to help support themselves and their families. Unfortunately young women are not often encouraged to explore occupational options that offer increased economic mobility. This article describes a program designed to develop awareness of nontraditional technical careers for women, careers that require less than four years of postsecondary education. Attended by guidance counselors and math and science teachers, the conference explored the psychological implications of nontraditional choices as well as provided information about these occupations. The article also discusses funding, program development and design, and evaluation.  相似文献

The media continue to exercise power in transmitting values. “Kramer vs. Kramer” made film history recently by claiming an impressive number of Oscars. Written reviews and televised acclamations repeatedly cited the authentic and sympathetic treatment of the parents. However, consistent with society's present attitude toward children, the ethical and legal rights of the child were not addressed. The plot underscored the paternalistic and utilitarian manner by which we approach problem-solving and decision-making which directly involve and affect children.  相似文献

Ellen Lenney 《Sex roles》1981,7(9):905-924
Previous investigators have suggested that women display lower self-confidence than men across almost all achievement situations. The empirical validity of this suggestion is assessed in an experiment testing the following hypotheses: (1) Sex differences in self-confidence depend upon the particular ability area. (2) Women's self-confidence is more influenced than men's by characteristics of the particular individual with whom they compare themselves. Undergraduates completed verbal, interpersonal perceptiveness, spatial-mechanical, and creativity subtests. After each subtest, subjects estimated both their own score and that of the average undergraduate, the average male undergraduate, or the average female undergraduate. Self-confidence was operationally defined in terms of how favorably subjects compared their work to that of their peers. As predicted, women's self-confidence was lower than men's in only the spatial-mechanical and creativity subtests; and for women, but not for men, self-confidence depended upon which peer was specified. It is concluded that situation variables do determine sex differences in self-confidence and that women's self-confidence may be unduly affected by situation-specific comparison cues.The preparation of this article was supported in part by a Doctoral Dissertation Fellowship in Women's Studies awarded to the author by the Woodrow Wilson National Fellowship Foundation. Some portions of the study reported in this article were presented at the Western Psychological Association 1976 Convention (Lenney, Note 1) and were briefly abstracted in another article (Lenney, 1977). The author wishes to express her deep appreciation to Walter Mischel and to Sandra Bem for their invaluable consultations on the writing of this article.  相似文献

It was hypothesized that sexual orientation is not an aspect of sex-role socialization, but is acquired during a sensitive period from birth to 3 years through physical contact with adults. This is tentatively supported by evidence suggesting that (a) sexual orientation is highly resistant to change after adolescence; (b) infants respond to sexual stimulation and discriminate between the sexes; (c) gender identity is fixed between birth and 3 years of age; (d) during their infancy, homosexuals were psychosocially and presumably physically responded to as children of the opposite sex; (e) parents touch boys and girls differently. Stronger support for the hypothesis must be gained from longitudinal observation of parent-infant physical and social interaction and the infant's eventual sexual orientation.  相似文献

Previous research indicates that the work of women is often devalued rela- tive to that of men. Two experiments tested the hypothesis that such sex bias appears when judges follow ambiguous guidelines or criteria in making evalua- tions, but not when they tollow clear evaluation guidelines. In each experiment, male and female undergraduates evaluated a performance that was attributed to either a man or woman (an intellectual test performance in Experiment I; an artistic craft object in Experiment 11). Subjects followed either clear, explicit evaluation criteria or vague, ambiguous criteria. As predicted, female subjects Lyaluated the "female's" performance less favorably than the "male's" only when. criteria were vague. In contast, male subjects showed little evidence of sex bias, regardless of the criteria they followed. Discussion centers upon: (1) possible cognitive processes underlying the observed effects of clear criteria; and (2) potential practical applications designed to alleviate sex bias in naturalistic settings.  相似文献
