Twenty subjects made magnitude estimations of the apparent heaviness of metallic stimulators of various masses and temperatures (cold, neutral, and warm). The stimulators were placed on the forearm at normal skin temperature (about 33°C), at elevated skin temperature (38°C), and at lowered skin temperature (25°C). Under neutral conditions, we replicated earlier studies: cold objects felt considerably heavier than neutral ones, warm objects somewhat heavier than neutral objects. Warming the skin essentially obliterated the intensifying effect of the warm objects but left unaltered the intensifying effect of the cold objects. Cooling the aim also essentially obliterated the intensifying effect of warm objects. It also diminished, but far from eliminated, the intensifying effect of cold objects. Cold intensification of touch sensation is a large and robust phenomenon and, unlike warm intensification, appears to characterize all body regions. 相似文献

We are building a computer-based instructional system for teaching the operation of complex physical mechanisms. The system is based intimately on the use of simulation. Our goal in this paper is to describe the system we are attempting to construct, discuss its origins, and identify what we perceive to be its implications for psychological research into instruction. 相似文献

Two experiments were performed on rats with hippocampal brain damage and on a control group with neocortical lesions. In the first experiment the hippocampal group learned a difficult visual discrimination as promptly as the controls, and neither group was subsequently impaired by adding relevant or irrelevant background cues to the original stimuli. In the second experiment the animals learned a simultaneous visual discrimination in which the stimuli differed in both brightness and orientation. The hippocampal group was impaired relative to the controls on acquisition, and showed poorer transfer to stimuli differing only in brightness or orientation. The results are incompatible with the hypothesis which attempts to explain the effects of hippocampal damage by a widespread reduction in sensory gating, but they are consistent with a more restricted version of the same hypothesis. 相似文献

This paper reports two companion studies which establish that there is a significant relationship between an individual's personality characteristics and his pattern of job-seeking behavior. Individuals who are tough-minded, independent and nonneurotic had specified job goals and self-actualized behavior. They were highly successful in obtaining jobs. Individuals who were sensitive, dependent and neurotic had vague goals and passive behavior. They failed to get jobs. Individuals who exhibited a mixture of the cited characteristics and behavior were also exploring career options. They had a modicum of success in obtaining jobs. Job-seeking behavior as a process of vocational development is discussed. 相似文献

This study was designed to assess the effects of failure on the subsequent test performance in school of young adolescents. Fifty-one seventh-grade students, identified as at-risk for future school failure, were compared to 51 randomly selected classmates on individually administered measures of intelligence, self-concept, problem-solving ability, coping ability, attribution, and locus of control. Teachers' ratings, mathematics ability, and grades of the two groups were also compared. Students with a history of school failure, although of normal intelligence, were found to be significantly less intellectually, academically, and affectively competent than their more successful peers and were rated by their teachers as significantly less able to deal adaptively with normal school stress. A discriminant analysis separated the groups with 93% accuracy. On two equivalent mathematics tests, one given under relaxed conditions, and the other under normal school test-like conditions, approximately thirty percent of both the at-risk and the otherwise normal students got lower scores when they thought they were taking a test. Implications of these results for the understanding and remediation of stress-depressed school performance are discussed. 相似文献

Abstract. There is good reason to suppose that religious belief and ritual are manifestations of the archetypal blueprint for human existence encoded in the genetic structure of our species. As a consequence, religion has become a focus of study for psychobiologists and neuroscientists. However, scientific explanations of religious experience do not "explain away" such experience nor are they substitutes for the experience itself. On the contrary, scientific discoveries may be seen as corroboration of religious insights into the unus mundus , the essential oneness of all experience, which links human nature with the nature of the cosmos. 相似文献

This study assessed the nature of the person-team fit relationships for extraversion on members' attraction toward their teams. Unlike most studies of personality-based fit, which emphasize similarity, we predicted that complementary fit on extraversion (i.e., high individual-low team or low individual-high team levels) would result in greater attraction to the team. Data from two independent samples of intact project teams were analyzed, including 324 MBA students comprising 64 case analysis teams and 217 members of 26 manufacturing teams. Using polynomial regression analysis and three-dimensional surface plots, our results supported the predicted relationship. In addition, the data indicated that individuals who were more attracted to their teams were also better performers, as judged by their peers and supervisors. 相似文献
