According to the learned helplessness hypothesis, the learning impairment typically displayed by subjects previously given insoluble problems results from the veridical learning of response-outcome independence. This learning is represented as a belief in helplessness which interferes with the subsequent acquisition of adaptive responses. However, this interpretation is suspect since subjects in a psychology experiment tend not to learn that random relationships are random. Instead, an alternative interpretation of these findings attributes the learning impairment following insoluble problems to a hypothesis pool alteration in the direction of (inappropriately) complex hypotheses. This alternative interpretation tended to be supported ported in Experiment 1, which varied the difficulty of the test task and found the impairment (relative to a no-treatment control) following insolubility to be inversely proportional to the test difficulty. In contrast, Experiment 2 employed a procedure which facilitated the attribution of response-outcome independence and found the impairment following insolubility to be directly proportional to the test difficulty. It was concluded that the results of Experiment 2 represented learned helplessness.  相似文献

49 pairs of counselors with and without teaching experience were asked to rate their relationships with others and their ability to perform certain school-related and guidance tasks. The pairs were obtained from throughout the United States. Counselor educators were asked to identify pairs who had graduated from their institution, were of the same sex, and were working in approximately the same situation. Ratings were then obtained using a mailed questionnaire. The major findings were: (1) After counselors had been on the job for 8 weeks or more they perceived no difference in their relationships with others in the school. (a) Counselors with teaching experience had significantly higher ratings of their ability to perform 4 of the 6 routine school tasks listed. (3) No significant differences were found in ratings of their ability to perform guidance tasks with the exception of providing vocational information. Counselors with teaching experience had higher ratings in this area.  相似文献

Eighty-two subjects (49 women, 33 men) solved a difficult or easy set of anagrams, after which they indicated their subjective level of performance, provided causal attributions, and stated expectations for future performance. Sex comparisons were conducted on each element in the attribution model. Results indicated no sex differences on subjective evaluation of success, on causal dimensions, on expectations for future performance, or on performance on a final set of anagrams.  相似文献

Effect of peer presence on the sex-typed toy choices of 3- and 4-year-olds was investigated in a repeated measures experimental design. Twenty-six girls and thirty-six boys were tested under three conditions: (a) alone; (b) in the presence of a same-sex peer; and (c) in the presence of an opposite-sex peer. Amount of time spent playing with three feminine- and three masculine-stereotyped toys was recorded. For both boys and girls, play with “sex role-inappropriate” toys was significantly lower in the presence of an opposite-sex peer than in the solitary condition. Across conditions boys exhibited less play with opposite-sex-typed toys than girls. Rate of play with opposite-sex-typed toys increased in successive trials for both sexes. These results indicate that the presence of an opposite-sex peer functions as a discriminative stimulus for avoidance of “sex role-inappropriate” play in preschoolers and suggests that preschoolers may have a history of differential reinforcement for sex-typed play in the presence of peers.  相似文献

Two experiments were conducted to test a buffer model of response selection. Subjects reacted to the onset of one of six possible visual stimuli by pressing either a left- or a right-hand key. Two stimuli were assigned to one key Itwo-item set) and four stimuli were assigned to the other key flour-item set). An irrelevant monaural tone accompanied the visual stimulus in Experiment 1 but not in Experiment 2. Results of Experiment 1 showed that reactions were faster when the location of the tone corresponded with the response than when it did not, and the difference between these corresponding and noncorresponding conditions was greater for the two-item set than for the four-item set. Results supported the notion that the response selection process involved a serial self-terminating search of response buffers and that the tone determined the buffer searched first. In both experiments, reactions were faster to stimuli from the twoitem set than to stimuli from the four-item set  相似文献

Two measures of sex-role preference were administered to 32 male and 32 female preschool children. Each group of children was divided according to sex-role preference scores, assigned to a male experimenter or a female experimenter, and performed two sorting tasks after being instructed that one task was masculine and the other feminine. One analysis was based on the sex preference of subjects as measured by the IT Scale for Children and the other was based on subject assignment from Toy Preference Test scores. The hypothesis that sex-role preference would predict performance on sex-labeled tasks was partially confirmed. All subjects performed better on the female task than on the male task and more accurately on all tasks with a male experimenter than with a female experimenter.This report is based on a master's thesis submitted to the University of Guelph by the first author. Acknowledgments are due to MacDonald, Aladdin, Jack and Jill, Wee Y'rs, Cambridge, and Christopher House preschools in Guelph and Cambridge, Ontario, for their cooperation.  相似文献
