To ascertain the veridicality of projected attitudes toward sex role behavior, 74 male and 74 female undergraduates filled out the Attitudes Toward Women Scale (AWS) using three different targets: self, typical female classmate, and typical male classmate. Analyses of variance on respondents' total AWS scores and on the six AWS subscale scores showed significant interactions between sex of respondent and sex of target for all seven variables. Since the directions of the interactions were not consistent across subscales, the results indicated the methodological necessity of using measurements which examine a variety of specific subclasses of sex role behaviors (rather than using unidimensional scale or total test scores) when stereotypic sex role attitudes are sought. In general, both sexes were found to have a fairly accurate perception of women's attitudes, but both sexes consistently perceived the typical male as more conservative than the male self-ratings justified.  相似文献

Based on evidence that Chinese yields more interference than English, Biederman and Tsao (1979) have suggested that the processes involved in reading Chinese are more similar to those involved in colour naming than are the processes involved in reading English. In three experiments conducted to evaluate the empirical foundation for this hypothesis it was found that: (1) Chinese yielded less interference than English (and French) in between-subjects comparisons involving Chinese-English bilinguals and English monolinguals or English-French bilinguals; (2) Chinese print did not yield more interference than English print in within-subjects comparisons involving the orthogonal combination of print language (Chinese or English) and naming language (Chinese or English) among Chinese-English bilinguals; and (3) compared with syntactic category, both language and orthography were relatively impotent variables in the object naming version of the Stroop task.  相似文献

Abstract

Public health agencies regularly survey randomly selected anonymous students to track drug use, sexual activities, and other risk behaviors. Students are unidentifiable, but a recent project that included school-level analysis discovered a school with alarmingly prevalent student suicidality. Given confidentiality protocols typical of surveillance, the surveyors were uncertain whether and how to intervene. We searched literature for duties to warn at-risk groups discovered during public health surveillance, but we found no directly applicable guidance or cases. Reasoning by analogy, we conclude that surveyors should contact the school’s leaders to call attention to its outlier status, but public warning is unwarranted. However, such an ad hoc decision to issue a warning, even if only to school leaders, raises significant practical, legal and ethical issues. National public health and education associations should produce guidance that clarifies ethical and legal duties owed to schools and students involved in population health-risk surveillance.  相似文献
