Many studies have examined sex differences in social physique anxiety; however, few researchers have examined possible perceptual differences in such anxiety based on ethnicity. The present purpose was to examine social physique anxiety among college-age women of Euro-American and African-American descent. Participants (N = 91) from physical activity classes at a university located in the southeastern United States completed the Social Physique Anxiety Scale. The participants were 67 Euro-Americans and 24 African Americans. An independent t test yielded a significant difference (p =.01) between groups on Eklund's scale, which supports the hypothesis.  相似文献

Modern experiments in the behavioral sciences frequently employ several items of electronic equipment such as computers, monitoring devices, stimulus presentation equipment, and response collection systems. In many cases it would be advantageous for these items to communicate directly with each other. Such communication may facilitate greater automation of experiments (i.e., reduced experimenter influences during the experiment), more precise experiment control (i.e., superior timing and synchronization capabilities of electronic devices), and greater accuracy of data collection (i.e., reduced ambiguity of participant responses). Many electronic experiment devices already provide external interfacesthrough which communication with other devices can be implemented. The most common is based on the RS-232 protocol, which is also found in all standard PCs. Therefore, Microsoft Windows based computers can be programmed to control experiments by communicating directly with electronic experiment devices. We show how to implement this RS-232 interconnection between devices and a Windows PC using currently available software tools.  相似文献

Reductions in latent inhibition (LI), the capacity to screen from conscious awareness stimuli previously experienced as irrelevant, have been generally associated with the tendency towards psychosis. However, "failure" to screen out previously irrelevant stimuli might also hypothetically contribute to original thinking, particularly in combination with high IQ. Meta-analysis of two studies, conducted on youthful high-IQ samples. demonstrated that high lifetime creative achievers had significantly lower LI scores than low creative achievers (r(effect size) = .31, p = .0003, one-tailed). Eminent creative achievers (participants under 21 years who reported unusually high scores in a single domain of creative achievement) were 7 times more likely to have low rather than high LI scores, chi2 (1, N = 25) = 10.69, phi = .47. p = .003.  相似文献

A novel modular connectionist architecture is presented in which the networks composing the architecture compete to learn the training patterns. An outcome of the competition is that different networks learn different training patterns and, thus, learn to compute different functions. The architecture performs task decomposition in the sense that it learns to partition a task into two or more functionally independent tasks and allocates distinct networks to learn each task. In addition, the architecture tends to allocate to each task the network whose topology is most appropriate to that task. The architecture's performance on “what” and “where” vision tasks is presented and compared with the performance of two multilayer networks. Finally, it is noted that function decomposition is an underconstrained problem, and, thus, different modular architectures may decompose a function in different ways. A desirable decomposition can be achieved if the architecture is suitably restricted in the types of functions that it can compute. Finding appropriate restrictions is possible through the application of domain knowledge. A strength of the modular architecture is that its structure is well suited for incorporating domain knowledge.  相似文献

This investigation applied Zautra and colleagues’ Dynamic Model of Affect (DMA; Zautra: 2003, Emotions, Stress and Health (Oxford University Press, New York); Reich et al.: 2003, Review of General Psychology 7(1), pp. 66–83) to help understand resilience among a sample of middle-aged participants coping with the recent death of a spouse or child. We replicated and extended this model by examining interaffect correlations (individual correlations between negative and positive affect over time) in resilient versus symptomatic bereaved people. As predicted by the DMA, resilient bereaved had weaker (or less negative) interaffect correlations than symptomatic bereaved even when controlling for self-reported distress. These findings suggest that resilient individuals possess a capacity for a more complex affective experience and that this capacity serves a salutary function in the aftermath of aversive life events. The research described in this article was supported by a grant from the National Institute of Health, R29-MH57274 (George A. Bonanno).  相似文献

This article describes an extensive audit of the work of government agencies against business crime in Sweden, as an example of a performance evaluation by an auditing institution. Business crime was shown to be a major and growing social problem. Manifold measures are required, and these must be directed and coordinated by the Government and the Riksdag. The cooperation of the commercial sector is also needed. The investigation was made by the Parliamentary Auditors of Sweden, which is the smaller of the two auditing institutions in the country. The method used in the investigation can be described as an “interactive” one. The intention was to create a thorough understanding of the issue and a shared approach to the problem. This aim seems to have been achieved to a great extent. Karin Rudberg is one of the audit directors at the Office of the Parliamentary Auditors of Sweden. She is an eonomist with experience in investigations of many different fields, such as restructuring government agencies, evaluation of energy research policies, and analyses of the Swedish industrial structure and labor market.  相似文献

The aim of this study was to assess individual and social antecedents of attachment security and attachment disorganization of infants as assessed by the Strange Situation. Observations from two longitudinal studies, with a parallel assessment schedule yielding a total sample of 88 infant-mother pairs, formed the database of the study. Newborn behavioral organization, in terms of orienting ability and regulation of state, and maternal sensitivity assessed several times during the infant's first year were used to predict the security of infant-mother attachment and the status of disorganization of attachment behavior strategies at the age of 12 months. Whereas attachment security was significantly associated only with maternal sensitivity, the status of disorganization was only predicted by newborn behavioral organization. The findings are discussed with respect to specific assumptions about individual and social contribution to the development of infant-mother attachment on the background of maternal attachment representation.  相似文献
