Reading comprehension, indicated by motor behavior and multiple-choice picture selection called for in written instructions, was taught to an autistic child using verbal prompts, modelling, and physical guidance. The child was rewarded for correct behaviors to training items; nonrewarded probes were used to assess generalization. Probable maintaining events were assessed through their sequential removal in a reversal design. Results showed: (a) following acquisition, performance was maintained at a near-100% level when candy, praise, attention, and training were removed, (b) absence of other persons was correlated with a marked decrease in performance, whereas their presence was associated with performance at near 100%, and (c) performance generalized to probes and across experimenters. Rewards, which may have been reinforcing during acquisition, did not appear necessary to maintain later performance. Instead, presence of others (a setting event) was demonstrated to have control over maintained performance. 相似文献

Participants ranging in age from 30 to 70 years free-recalled when they had learned public and private items of news. When responses were plotted in terms of age of participant at time of encoding, it was found that peak recall for public items of news was in the period when participants were aged 10 to 19 years whereas peak recall of private items of news occurred in the period when participants were aged 20 to 29 years. A second study confirmed this pattern of an early reminiscence bump for public news. It is proposed that these two components of the reminiscence bump reflect, respectively, a period of formation of generation identity in the second decade of life and a period of formation of intimate relationships in the third decade. 相似文献

Two studies analyzed the effects of preceding setting events on the problem behavior of students with severe disabilities. Using ABAB withdrawal designs, the occurrence versus nonoccurrence of preceding setting events was analyzed in relation to the frequency of problem behavior. Data were collected throughout a student's school day, with interventions focusing upon the elimination of setting events that occurred before school. The results indicate that (a) the occurrence of preceding setting events was related to higher frequencies of problem behavior and (b) interventions designed to eliminate preceding setting events were consistently associated with low frequencies of problem behavior. 相似文献

Exposure to chronic stress is associated with habitual learning in adults. We studied the origins of this association by examining the link between stressful life events and infant cognitive flexibility. The final sample consisted of N = 72 fifteen-month-old infants and their mothers. Mothers completed a survey on pre- and postnatal negative life events. To assess chronic stress physiologically, infant and maternal hair cortisol concentrations were determined for cortisol accumulation during the past 3 months. Each infant participated in two cognitive tasks in the laboratory. An instrumental learning task tested infants’ ability to disengage from a habituated action when this action became ineffective (Seehagen et al., 2015). An age-adequate version of the A-not-B task tested infants’ ability to find a toy at location B after repeatedly finding it at location A. Correlations between cortisol concentrations and postnatal negative life events (number, perceived impact) did not yield significance. Infant and maternal hair cortisol concentrations were not correlated. Infants’ ability to shift to a new action in either task, controlled for acute stress, correlated neither with pre- and postnatal negative life events nor with cortisol concentrations. Taken together, these results indicate that the potential link between long-term stress exposure and cognitive flexibility might not be present in samples with low levels of psychosocial stress. 相似文献

It is known that a major world event caused by one group can influence perceptions of other social groups. The impact of the events of September 11, 2001 on religious and ethnic discrimination in the UK was assessed. Of seven ethnic groups, Pakistanis and Bangladeshis, who were primarily Muslim, reported the greatest increase between pre- and postevent discrimination. So, the attacks on the USA by al-Qaeda, a radical Islamic organization, activated discrimination against people of Islamic faith in the UK. These results highlight links between world events and intergroup relations, and may serve to remind norm violators that the harm they do to people of other groups can impact people of groups perceived to share their values, even in geographically distant places. 相似文献

大学生领悟社会支持的影响因素研究 总被引:22,自引:1,他引:21
该研究以371名大学生为被试,考察了个体的幸福感、控制感和压力对领悟社会支持的影响。结构方程模型分析的结果显示:个体属性和情境因素都直接或间接影响着大学生对社会支持的理解和评价;个体属性的影响相对比较重要;在情境因素中,累积压力比当前压力的影响更为重要。本研究结果表明,领悟社会支持是在个人属性的作用下,个体在不断应对日常生活压力的过程中形成和发展的。 相似文献
