The effects of a graduated prompting treatment procedure were analyzed in three phases of an experiment on the training and generalization of reaching-grasp responding in 2- to 4-year-old blind, severely or profoundly retarded children. In Phase 1, we used a multiple-baseline across-subjects design to investigate the effectiveness of the treatment on midline reach-grasp responding. In Phase 2, we used a reversal design to investigate the effects of repeated implementations and withdrawals of the treatment. In both phases, generalization to right and left positions was measured. In Phase 3, in a multiple-baseline across-responses design, the treatment was implemented in right and left positions. Also in Phase 3, shift of stimulus control from toy-sound to verbal instructions was measured. The results showed that (a) the graduated prompting procedure was effective in training reach-grasp responding in all three children; (b) for one child, the effects were durable over repeated applications of the treatment procedure, but were not maintained during withdrawals; (c) for another child, the treatment procedure was effective in teaching reach-grasp responding in all three positions; and (d) for the same child, training of reach-grasp responding generalized to toys presented without sound, given only the verbal instruction. 相似文献

Children in grades 2–10 (200 of each sex) assigned desirable and undesirable traits to girls or boys. Half the subjects had an additional option of both sexes. Children in all grades assigned more desirable traits to their own sex and more undesirable traits to the opposite sex, in line with Smith (1939). Both sexes became less positive toward their own sex and more positive toward the opposite sex with increasing age. This pattern also had characterized girls in Smith's study, whereas, boys had shown the opposite pattern. Beginning in the sixth grade, girls were more apt than boys to assign desirable traits to their own sex. Availability of the “both sexes” option decreased stereotyping, especially in girls. 相似文献

The purpose of this study was to investigate independent and interactive effects of physical attractiveness (PA), sex, and task sex-typing on performance evaluations. Subjects were 216 college women who read poorquality essays written on masculine, feminine, or neutral topics. Essays supposedly were written by a male or a female student who was either attractive, unattractive, or physically unidentified. Results indicated that PA enhanced evaluations of both male and female essayists, except for the predicted effect that female attractiveness is less beneficial for masculine than feminine task performances. Women did not evaluate the sexes differently, and sexism was largely restricted to the interactive effects of PA. PA stereotypes also affected causal attributions of performers' outcomes in a manner consistent with attribution theory. These data are considered in the context of the existing literature and the directions for further research on sexism and beautyism. 相似文献

In two experiments, fear was conditioned to the situational cues in one compartment of a hurdle-jumping apparatus and was then extinguished. Subsequently, either one shock (Experiment 1) or three or nine shocks (Experiment 2) were given in a situation distinctively different from that in which conditioning and extinction had taken place. Although some associative strength between the situational cues and fear was shown to have remained after extinction, in neither experiment did the postextinction-shock treatment increase the fear elicited by these cues: Escape-from-fear performance was no better in the shocked groups than in control groups given no additional shock. Thus, the nonassociative hypothesis which postulates that inflating the value of the representation of the UCS with shock-alone presentations can reinstate the extinguished fear of a stimulus was not supported. Rather, the results showed that, after extinction, an increase in fear of a simulus depended on further conditioning to that stimulus. The data also indicated that the nonvisual components of the situational cues predominated over the visual component. 相似文献

Nietzsche's On the Genealogy of Morality is strikingly book-ended by the theme of knowledge-seeking: the Preface opens with the ominous claim that “[w]e are unknown to ourselves, we knowers”, and the Third Essay's climax is the assertion that scientific, scholarly activity does not stand in opposition to the ascetic ideal but is instead only that ideal's most recent and insidious instantiation. This feature of the text is absent from Reginster's The Will to Nothingness. Nonetheless, the interpretive machinery that Reginster develops in his reading of the Genealogy as a genealogy and critique of morality can also go a long way towards helping us to make sense of the text as, at the same time, a genealogy and critique of knowledge-seeking. Making use of Reginster's account in this way serves to illuminate both the interpretive power and some of the limitations of his reading. 相似文献

This study investigated whether political endorsements from in- versus out-group political elites would influence likelihood of COVID-19 vaccination. In March 2021, we ran an experiment with Democrats and Republicans in the United States to examine whether they would be more likely to get vaccinated following endorsements by former Presidents Obama or Trump. Participants reported greater likelihood of getting vaccinated if the vaccine was endorsed by an elite from their own rather than the opposing party. This effect was driven by Trump, who increased vaccination likelihood among Republicans but decreased it among Democrats. We also investigated the mechanisms underlying this persuasion effect and found that perceived bias and liking were plausible mediators, whereas perceived trustworthiness and expertise were not. This study highlights the potential of having endorsements from both Democrat and Republican political elites to increase support for health behaviors in a politically charged climate. 相似文献

Attention is focused on some of the factors which may result in the invalidation or distortion of both objective and subjective evaluations of students from the lower socioeconomic strata of the population. These factors include: (a) counselor attitude in evaluation; (b) counselee attitude in evaluation; (c) counselor-counselee value systems; (d) test weaknesses such as low reliability and/or validity and inadequate norms; and (e) a lack of understanding by the counselor and/or counselee of the purpose for testing. Evaluation is an integral part of the counseling process; however, the effectiveness of the evaluative process is dependent upon the counselor's knowledge and sense of responsibility as well as the validity and reliability of the tests. 相似文献

Briefs about mentally retarded people are more negative than briefs about other social categories; professionals, such as medical doctors evaluate them most negatively of all. It was hypothesized (a) that medics' beliefs about mentally retarded people are mediated by psychological salience of their clinical social identification, rather than by personal characteristics that medics happen to share and (b) that such beliefs will bias decisions, rather than enhance accuracy. Forty-five doctors and medical students were randomly assigned to conditions designed to enhance salience of their shared clinical social identification or individual self-perceptions. Subjects completed semantic differentials about mentally retarded people and distinguished between slides of ‘mentally retarded’ and ‘normal’ children. Beliefs of subjects in the medical condition were significantly more negative than those in the personal condition. A signal detection analysis revealed no difference between conditions in subjects' ability to distinguish between children but showed that subjects in the medical condition were significantly more likely to judge a child ‘mentally retarded’ when in doubt. Results were discussed within an information processing framework and supported the idea that a salient clinical social identity can mediate beliefs that are likely to handicap patients. 相似文献
