The role of women in the People's Republic of China has changed dramatically in the last 40 years. This study assesses what impact these changes have had on the attitudes of Chinese youth. The sample consisted of 164 subjects (77 men and 87 women) who completed the Bem Sex Role Inventory, the Objective Fear of Success Measure, a locus of control scale, and a personal goals questionnaire. They also evaluated a painting attributed to artists of different gender and status. The results indicate that the sex role orientations of Chinese students were similar to those of American students. On the Bem inventory, the direction of the sex differences on the sex role scales was the same for U.S. and Chinese students, but the latter had a sex role orientation that, in our culture, is regarded as more “traditional.” Chinese women were significantly more likely to endorse statements expressing fear of success than were Chinese men. On the locus of control measures, Chinese women were more likely than men to attribute their achievement successes to luck and failures to a lack of ability. The women students also attributed affiliation outcomes more to luck than did the men. The most important personal goal cited by both men and women was that of career success. Chinese men placed greater importance than women on achieving wealth, and their expectancy of actually becoming wealthy was higher. Finally, in an evaluation of a painting, Chinese men, but not the women, devalued a painting when it was supposedly the work of a female student artist. 相似文献

Two cebus monkeys, with many years of experience matching a variety of static visual stimuli (forms and colors) within a standard matching-to-sample paradigm, were trained to press a left lever when a pair of displayed static stimuli were the same and to press a right lever when they were different. After learning the same/different task, the monkeys were tested for transfer to dynamic visual stimuli (flashing versus steady green disks), with which they had no previous experience. Both failed to transfer to the dynamic stimuli. A third monkey, also with massive past experience matching static visual stimuli, was tested for transfer to the dynamic stimuli within our standard matching paradigm, and it, too, failed. All 3 subjects were unable to reach a moderate acquisition criterion despite as many as 52 sessions of training with the dynamic stimuli. These results provide further evidence that, in monkeys, the matching (or identity) concept has a very limited reach; they consequently do not support the view held by some theorists that an abstract matching concept based on physical similarity is a general endowment of animals. 相似文献

Three pigeons pecked at letters of the alphabet and at the symbol "?" displayed on a computer-driven cathode ray screen. A 4 by 4 matrix of infrared emitting and detecting diodes and associated circuitry identified the location of a pigeon''s responses to the screen. Responses at the target letter T were probabilistically reinforced with food whenever T appeared in a string of three letters in the middle of the screen. Responses at the symbol "?" appearing below this string were probabilistically reinforced whenever T did not appear. The letter F anywhere in the three-character string either strongly predicted the occurrence of the target letter T, in two conditions, or predicted its nonoccurrence, in a third. This manipulation of the frequency with which the familiar letter F predicted T was shown to change the function relating probability of a correct peck at the symbol "?" to the number of Fs in the string. This effect may be interpreted as an instance of the phenomenon where an organism''s acquired knowledge changes what it sees. 相似文献
