Extensive research on print media for children such as storybooks reveals that gender stereotypes are prevalent; however, no systematic analysis of coloring books has been conducted since 1974. We analyzed 889 characters in 56 contemporary coloring books published in the United States and selected through stratified random sampling from one region of California, coding for prevalence of each gender, stereotypic gender roles, activity level, type, and age of character. As hypothesized, males were more active; gender stereotypes were common. Gender neutral behaviors were more likely to be done by males. Females were more likely to be depicted as children and humans; whereas males were mostly depicted as animals, adults, and superheroes. Results are discussed in terms of gender schema theory.  相似文献

Perceptual learning on inspection time and motion perception   总被引:2,自引:0,他引:2  
Perceptual learning on simple perceptual tasks is interpreted as plasticity of neuronal populations in the sensory cortex (M. Fahle & T. Poggio, 2002). The authors examined individual differences on perceptual learning for 2 tasks-inspection time (IT) and a motion direction discrimination task that was instantiated as random dot kinematograms. The authors' main questions were whether individual differences in perceptual learning were consistent across the 2 tasks and whether perceptual learning correlated with cognitive abilities test scores. In all, 56 young adults completed 16 threshold estimations on 1 of 2 orthogonal versions of each task. Then, the authors made 2 further threshold estimations for the untrained, orthogonal version. Participants also completed a battery of 6 cognitive abilities tests that measured fluid ability (Gf) and perceptual speed (Gs). Perceptual learning was demonstrated for both tasks, but the degree of learning across tasks was not characteristic of the individual. Learning on IT correlated with Gs (r = .35), but learning on the motion direction discrimination task was unrelated to cognitive ability. Correlations of IT with cognitive measures were stable over the training period. IT was correlated with both the motion direction discrimination task (r = -.39) and an unmasked line length judgment task (r = -.31). The authors concluded that perceptual learning on IT correlates with cognitive abilities test scores, that correlations of IT with cognitive abilities test scores are stable as task performance improves with practice, and that the IT task is psychologically complex.  相似文献

To test Bem's (1979) hypothesis that androgynous and sex-typed individuals are differentiated by the presence or absence of beliefs in “gender polarity,” 200 students rated themselves on the short Bem Sex Role Inventory (BSRI). Of these 200, 20 androgynous women, 20 androgynous men, 20 feminine sex-typed women, and 20 masculine sex-typed men were randomly selected and asked to rate either the ideal woman or the ideal man on the short BSRI. As predicted, androgynous women did not rate the ideal man and woman differently, but, contrary to prediction, neither did feminine-typed women. As predicted, masculine-typed men rated the ideal man and woman differently, but, contrary to prediction, so did androgynous men. Thus, sex rather than sex-role distinguished subjects' beliefs in gender polarity. This finding may reflect women's desires for, and men's fears of, abandoning traditional modes of sex differentiation. The large initial subject pool was necessary because an extremely high percentage of subjects were classified as feminine sex-typed. An apparent feminine bias in the short BSRI is discussed.  相似文献
