Three experiments are described which elaborate some of the conditions under which rats will contact and manipulate a periodically presented retractable lever. Experiment 1 demonstrated that (i) initial manipulative oral and manual contact with the lever was facilitated if the rat had previous experience of food delivery in the experimental chamber; (ii) persistence in contacting the lever on successive presentations was a function of whether food continued to be presented in the experimental environment; and (iii) food satiation significantly reduced the tendency of the rat to contact the lever even though an expectancy of food had previously been established under conditions of food deprivation. Experiment 2 suggested that the tendency to approach and contact the lever was in part a function of the local moment-to-moment conditional probability of food delivery. Experiment 3 found that the probability of contacting the lever was higher during presentation of an auditory CS signaling a high rate of food delivery than during stimuli signaling no food at all. These results are interpreted as suggesting that the food-signaling aspects of an appetitive CS and that CS's ability to generate signal-directed behaviors are experimentall separable properties. 相似文献

This paper examines the effect of spectators on women’s football games. COVID-19 and related restrictions provide a unique opportunity with an adequate sample size to test the effect of lockdown on sports activities. Studies have recently exploited this opportunity for men’s football to better understand the potential causes of home advantage and, more specifically, assess the psychological consequences when matches are played without supporters. Despite the increased scientific interest, there was only one paper that focused on women’s football. Therefore, we aim to contribute to this research field by considering matches from four major European women’s football leagues. The findings suggest that for three of these leagues, lockdown has a statistically significant effect on the sanctioned yellow cards by either reducing the number of yellow cards sanctioned to the away teams or increasing the number of yellow cards sanctioned to the home teams. Nonetheless, lockdown does not affect any final match outcomes; therefore, it does not significantly affect the magnitude of home advantage for women’s games. 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

中国和澳大利亚父母报告的儿童社会性发展 总被引:4,自引:1,他引:3
采用作者编制的《3-9岁儿童社会性发展量表》的英译本,在284名澳大利亚儿童中进行测试。结果表明,对于社会文化背景差异巨大的中国和澳大利亚,本量表具有较好的稳定性和跨文化适用性。儿童社会性发展的各个方面,在中澳父母心目中占有不同地位:中国父母重视自我意识、社会技能、意志品质,而澳大利亚父母更重视社会技能和社会情绪的发展。在中澳两个样本中,女孩的社会性发展量表得分均高于男孩。 相似文献

小学儿童奖赏公平性的认知发展 总被引:2,自引:0,他引:2
采用信息加工研究途径并假设故事情境探索小学儿童对奖赏公平性的社会认知发展,并将儿童的发展与成人作对比。研究结果表明,7,9岁儿童容易将"均等"与"公平"混淆,还没形成一个稳定的分配模式,而12岁儿童已能运用"努力"、"成果"、"能力"等规则较为稳定地作出公平奖赏决定或评价,但还没达到对更高层次的社会准则的理解和掌握。儿童这一发展制约于他们的信息加工能力以及获得有关社会价值观的社会化过程。 相似文献

In order to better understand how an integrated mindfulness and acceptance-based intervention works and for whom it works best, study objectives were to examine (i) the trajectories of mindfulness skills and performance-related outcomes during the intervention, and athletes’ perceptions of the impact of the intervention; and (ii) the potential moderating effects of personality characteristics on changes in targeted variables associated with the intervention. The sample consisted of 40 young elite female basketball players (M = 16.33, SD = 0.75 years) from three incoming groups at the French Federal Basketball Center over a 3-year period. All players participated in a 15-week Mindfulness BasketBall Integrated program. They completed online questionnaires measuring personality traits 10 months before the intervention, as well as pre-, mid- and post-intervention measurements of mindfulness skills, intensity and directional interpretation of stress, and performance satisfaction. They also participated in semi-structured social validation interviews conducted one month after the intervention. The results of the multilevel growth curve (MGCA) and thematic analyses revealed how the mindfulness skills and performance-related outcomes evolved over the course of the intervention and how these changes were perceived by the athletes. Specifically, the MGCA showed significant linear increases in acceptance, positive stress direction, and performance satisfaction. The complementary social validation data indicated perceived improvements in mindfulness skills and performance. The MGCA also showed that baseline personality traits moderated the effects of the program on acceptance and experience of stress. These findings may be used to inform the design of more effective integrated mindfulness and acceptance-based interventions. 相似文献

In response to Robert Young's critical comments concerning Hermeneutics and Education I clarify two issues. First, I suggest that a more detailed account of interpretation and learning could be developed in a hermeneutically informed cognitive psychology. This would be an account that escapes the textual model of silent reading construed as private mental experience, and that acknowledges the social and communicative dimensions of understanding. Second, in contrast to Young's view, I contend that phronesis is not reducible to a set of inner thought processes and that it has a role to play even in a critical social theory of education. 相似文献

The present study examined the validity of the Social Problem-Solving Inventory (SPSI) and SPSI—Revised in differentiating 65 high-suicidal from 63 depressed, low-suicidal college students. Results from multivariate analyses indicated overall differences in problem-solving between these two groups as measured by the SPSI but not by the SPSI-R. Further examination of these differences revealed the high-suicidal group was different in problem-solving orientation, rather than problem-solving skills, compared to the depressed, low-suicidal group. However, when depression was statistically controlled in hierarchical regression analyses, none of the problem-solving measures predicted group membership. The superiority of the SPSI to the SPSI-R in differentiating these two groups appears to be accounted for by the elimination of 28 items in the revised version, many of which measure orientation to problem-solving. Also explored was the possibility that objective measures of problem-solving provide a better prediction of adjustment than do self-report measures. 相似文献

In this paper I formulate an approach for evaluating probabilistic forecasts in terms of signal detection theory. Signal detection theory provides a powerful perspective for this type of problem, and a rich empirical background including methodological tools as well as an extensive body of research in many domains. I propose procedures which emphasize the maximization of expected utility for the decision maker who uses the forecasts. Further, I suggest approaches to obtaining indices of calibration and resolution within this framework. I also present arguments that the proposed indices will exhibit the same basic properties as do decompositions of Brier's (1950, Monthly Weather Review, 78, 1–3) mean probability score. However, the properties may be reflected in different ways, and hence, the present methods may lead to different conclusions about forecasting ability. Finally, I argue that the use of an expected utility loss function makes this approach more appropriate for practical applications as well as for theoretical research than other procedures with more arbitrary loss functions. 相似文献
