Subjects viewed a videotaped group discussion by a leader and four other group members and evaluated each of them for leadership competence. The leader, either a man or a woman, was either personally endorsed ("legitimized") or unendorsed by either a male or a female authority figure. Legitimation raised both leaders' performance evaluations. Legitimation by the female authority affected the leaders' evaluations, overall, as much as legitimation by a male authority. For the male leader, legitimation by the male and female authority figures produced equal impact. However, legitimation by the female authority figure produced significantly greater impact on evaluations of the female leader's performance than the same legitimation by a male authority figure. The data suggest that female authority figures can be effective legitimizers of both sexes, but male authority's endorsements of a female subordinate may be viewed as suspect. 相似文献

Parents of 43 conduct-problem children, aged 3-8 years, were randomly assigned to one of two treatments: an individually self-administered video-tape modeling treatment (IVM) and IVM treatment plus therapist consultation (IVMC). Randomization also included a waiting-list control group (CON). Compared with the control group, both treatment groups of mothers reported significantly fewer child behavior problems, reduced stress levels, and less use of spanking. Home visit data indicated that both treatment groups exhibited significant behavioral changes. There were relatively few differences between the two treatment conditions. However, the IVMC children were significantly less deviant than the IVM children, suggesting that the IVMC (with therapist consultation) treatment was superior to self-administered treatment with no therapist involvement. The added benefits of therapist involvement are discussed. 相似文献

GENDER COMPARISONS OF MATHEMATICS ATTITUDES AND AFFECT 总被引:5,自引:0,他引:5

This article reports the complex results of meta-analyses of gender differences in attitudes and affect specific to mathematics. Overall, effect sizes were small and were similar in size to gender differences in mathematics performance. When differences exist, the pattern is for females to hold more negative attitudes. Gender differences in self-confidence and general mathematics attitudes are larger among high school and college students than among younger students. Effect sizes for mathematics anxiety differ depending upon the sample (highly selected or general). One exception to the general pattern is in stereotyping mathematics as a male domain, where males hold much more stereotyped attitudes ( d = -.90). While affect and attitudes toward mathematics are not the only influences on the development of gender differences in mathematics performance, they are important, and both male and female affect and attitudes should be considered in conjunction with other social and political influences as explanations. 相似文献

Six experiments explored the hypothesis that the members of categories which are considered most prototypical are those with most attributes in common with other members of the category and least attributes in common with other categories. In probabilistic terms, the hypothesis is that prototypicality is a function of the total cue validity of the attributes of items. In Experiments 1 and 3, subjects listed attributes for members of semantic categories which had been previously rated for degree of prototypicality. High positive correlations were obtained between those ratings and the extent of distribution of an item's attributes among the other items of the category. In Experiments 2 and 4, subjects listed superordinates of category members and listed attributes of members of contrasting categories. Negative correlations were obtained between prototypicality and superordinates other than the category in question and between prototypicality and an item's possession of attributes possessed by members of contrasting categories. Experiments 5 and 6 used artificial categories and showed that family resemblance within categories and lack of overlap of elements with contrasting categories were correlated with ease of learning, reaction time in identifying an item after learning, and rating of prototypicality of an item. It is argued that family resemblance offers an alternative to criterial features in defining categories. 相似文献

Following training on schedules which differentially reinforce low rates of responding (DRL), three rats were exposed to a procedure to test for external inhibition. During test trials, a tone was presented midway in the DRL interval and the latency to the next response recorded. The incidence of external inhibition (defined in terms of the latency and its relative probability) appeared to be positively related to the size of the DRL schedule and not to measures of the subject’s “efficiency” on the schedule. An alternative view to the “pure” disinhibition hypothesis is presented which stresses the disruption of collateral behavior sequences which maintain responding under the DRL schedule. 相似文献

Basic objects in natural categories 总被引:1,自引:0,他引:1

Categorizations which humans make of the concrete world are not arbitrary but highly determined. In taxonomies of concrete objects, there is one level of abstraction at which the most basic category cuts are made. Basic categories are those which carry the most information, possess the highest category cue validity, and are, thus, the most differentiated from one another. The four experiments of Part I define basic objects by demonstrating that in taxonomies of common concrete nouns in English based on class inclusion, basic objects are the most inclusive categories whose members: (a) possess significant numbers of attributes in common, (b) have motor programs which are similar to one another, (c) have similar shapes, and (d) can be identified from averaged shapes of members of the class. The eight experiments of Part II explore implications of the structure of categories. Basic objects are shown to be the most inclusive categories for which a concrete image of the category as a whole can be formed, to be the first categorizations made during perception of the environment, to be the earliest categories sorted and earliest named by children, and to be the categories most codable, most coded, and most necessary in language. 相似文献

Questionnaire responses of second- and third-grade teachers specially selected because of their relatively high consistency in producing student learning gains on standardized achievement tests (N =30) were compared with responses of other teachers working in the same school system at the same grade levels (N = 38). Due to sample selection procedures, the highly consistent teachers were older and averaged more years of teaching experience than the teachers in the comparison group. In order to see whether the consistent teachers differed in any other ways from the teachers in the comparison group, the teachers in each group were administered a 495-item questionnaire. Group difference analyses revealed 57 items showing differences beyond the .05 level of significance, when only about 25 would have been expected by chance. For the most part, the items showing group differences did not form interpretable patterns. However, a subset of 10 items emerged from a factor analysis to form a traditionalism factor. Further analyses revealed that the highly consistent teachers were more traditional in their attitudes and beliefs than the teachers in the comparison group, and that this difference was not related to teacher age or years of experience. Thus, traditionalism in beliefs and attitudes was related to consistency in relative success in producing student learning gains. Possible reasons for this puzzling finding are discussed. 相似文献

Subjects were asked to detect either repetitions, rhymes, or words from the same category during an auditory or visual list presentation. It was discovered in both cases that the number of intervening words had a differential effect on probability of detection, with phonemic feature detection deteriorating more rapidly than semantic. However, "rate" of presentation did not have a differential effect on the probability of feature detection, since phonemic and semantic feature detection improved equally with increased interword interval time. It was suggested that phonemic feature retention might be more vulnerable than semantic feature retention to interference. 相似文献

Four experiments examined the hypothesis that the Valins (1966) false physiological feedback effect with attractiveness ratings of slides is due to experimenter demand. Experiments 1 and 2 showed significant feedback effects with 5-sec feedback periods, previously reported by Barefoot and Straub (1971) to be too brief a time to search the slides for a cause of the apparent physiological arousal. Experiments 3 and 4 had 17 variations of instructions (emotional, nonemotional), stimuli (slides of people, scenic tourist slides), and type of feedback information (heart rate, eyeblink, or none). The typical false feedback effect was found under many conditions that did not seem to meet the presumptive attributional requirements for the effect. In Experiment 4, only subjects who said they were supposed to rate feedback slides higher showed the effect, regardless of instructions, stimuli, or type of feedback. The overall results are interpreted in terms of experimenter demand and stimulus salience effects. 相似文献
