We examined temporal changes in salivary cortisol in response to a peer self-presentation task in a group of seven year-olds, some of whom scored high, average, and low on the Harter, 1983 Perceived Social Competence Scale. Salivary cortisol was measured pre-task, and 20 and 35 min post-task. We found a significant relation between individual differences in perceived social competence and salivary cortisol reactivity in response to the task. Children who perceived themselves as socially competent exhibited a significantly greater decrease in salivary cortisol from 20 to 35 min following the task compared with children who self-reported a relatively lower degree of social competence. We speculate on the meaning of salivary cortisol changes in childrens socio-emotional development. 相似文献

This is a reply to comments on my paper Cog, a Humanoid Robot, and the Questions of the Image of God ; one was written by Mary Gerhart and Allan Melvin Russell, and another one by Helmut Reich. I will start with the suggested analogy of the relationship between God and us and the one between us and the humanoid robot Cog and will show why this analogy is not helpful for the dialogue between theology and artificial intelligence (AI). Such a dialogue can succeed only if both our fascination for humanoids and our fear of them are equally accepted. Any avoidance of these emotions, as well as any rejection of the possibility that Cog might one day be humanlike, destroy the dialogue. The interpretation of both scientific theories and religious metaphors as stories replaces seemingly "rational" arguments with the confession of the respective commitments to a body of stories and opens up a space for exchange and friendship between AI-researchers and theologians—an option that usually remains closed. 相似文献

Investigated the psychometric properties of the Social Anxiety Scale for children-Revised (SASC-R) as well as relations between social anxiety and children's social and emotional functioning. Participants were a clinic sample of children, ages 6–11 with anxiety disorders (N = 154) who completed the SASC-R. For a subset of these children, parent ratings of social skills, and self-ratings of perceived competence and peer interactions were also obtained. Factor analysis of the SASC-R supported the original three-factor solution and internal consistencies were in the acceptable range. Among children with simple phobia, scores on the SASC-R differentiated those with and without a comorbid social-based anxiety disorder. Social anxiety was also associated with impairments in social and emotional functioning. Specifically, highly socially anxious children reported low levels of social acceptance and global self-esteem and more negative peer interactions. Girls with high levels of social anxiety were also rated by parents as having poor social skills, particularly in the areas of assertive and responsible social behavior. 相似文献

This essay forges links between Popperians and feminists by considering the connections between Donna Haraway's situated knowledge and Karl R. Popper's situational logic. It is concerned with the political commitments behind methodological issues, with the degree to which there can be a Popperian contribution to the feminist vision of a successor science, and with ways of dealing with, while not resolving, the political differences between socialist feminists and libertarian Popperians. 相似文献

An excessive “dropout” rate among police officers—quitting prior to normal retirement—wastes resources and may result in a low level of experience. Denmark's police force appears to be a case study in low turnover and may provide valuable insights. A primarily qualitative analysis contends that factors related to Danish culture and police practices produce relatively low stress and high “need fulfillment” for Danish officers in comparison with their counterparts in typical U.S. police departments—variables previously found related to low turnover. Results of a mail questionnaire show rates of early leaving (prior to retirement) notably lower for the Danish police than for a U.S. national sample of 87 police departments in large cities, and a special subsample of 39 small-city departments in California. Qualifications and implications are discussed. 相似文献

The utility of teacher judgment (rankings, ratings) and peer judgment (sociometric ratings) were studied as screening variables for preschool social withdrawal/responsiveness. Observational measures of preschoolers' interaction were used as the validation criterion based upon theoretical, empirical, and practical considerations related to development of a multipurpose behavioral assessment system. Results indicated that teacher rankings of students' verbal interaction frequencies (1) were most highly correlated to interaction rate in two preschool settings, (2) had test-retest reliability consistently above Rho = .80, and (3) were useful in that 77% of teachers using this procedure could identify their least socially responsive student within five rankings. The peer nomination sociometric rating was the least reliable measure at retest (Rho = .35) and showed consistently the lowest correlation with observational indices of interaction partner preferences, e.g., reciprocal rate (Rho = .29 to .39). The tendency for relationships among screening measures and the criterion to increase at retest suggested a training effect on screening accuracy. The use of teacher rankings in combination with observational measures to confirm selection accuracy and for monitoring treatment progress is discussed as a cost-effective behavioral assessment procedure for preschool social withdrawal/responsiveness. 相似文献

In contrast to most recent studies of human aggression, multiple measures of naturally occurring aggressive behavior were examined in a realistic and involving setting. Consistent with attributional formulations, it was found that aggression increased in accord with attributions of blame, and that more blame was attributed to another in response to inadequately justified thwartings than to adequately justified thwartings. As anticipated, anger, other-directed attributions of blame, and other-directed aggression were greatest in response to unjustified (illegitimate) thwartings. Justified (legitimate) thwartings produced intermediate anger and intermediate levels of blame and aggression internally and externally. Self-caused (internal) thwartings, ostensibly caused neither by the other's disposition nor by situational factors, produced the least anger and other-directed aggression but the most self-blame/self-aggression. In addition, unexpected thwartings produced independently more anger than did expected thwartings, and high-drive thwartings produced independently less other-directed aggression than did low-drive thwartings. The results are discussed with reference to both the need and the potential for studies of human aggression which employ more ecologically valid settings and measures of aggressive behavior. 相似文献
