Tympanic thermometers were used to measure fluctuations in the temperature of the left and right hemispheres of 22 normal high school students while performing verbal and nonverbal visual discrimination tasks. The nonverbal task involving face recognition demonstrated the predicted effect of hemispheric bias on performance: The subjects performed better when they showed a relative rise in right-hemisphere temperature. No significant relationship between hemispheric temperature and level of performance was observed during the verbal task, perhaps owing to the opportunity to treat effectively the nonwords as either linguistic strings or visual patterns. It is concluded that tympanic temperature effectively measures hemispheric activity during cognitive processing. 相似文献

College students of both sexes served as their own controls to test three hypotheses in each of two separate experiments designed to assess the learning effects of knowledge of results upon time estimation. The results indicated that (1) knowledge of results in the form of feedback to the nearest hundredth of a second significantly increased the mean accuracy of time estimations obtained by the method of production, (2) that knowledge of results significantly decreased the variance of the time estimations, and (3) that sex difference as a main effect was not significant in either experiment. A major conclusion of the present study was that variance represents an authentic and independent measure of learning. 相似文献

Human figure drawings of 12 pediatric oncology patients were significantly smaller in height, width, and area than were drawings of 12 school children and 12 pediatric general surgery patients paired for sex and age. The Goodenough-Harris scores of the cancer patients' drawings were also significantly lower than those of both school and general surgery groups. It is hypothesized that anxiety, lowered self-esteem, and the effects of chemotherapy contributed to these findings. 相似文献

Subjects in a prior study of complex learning often experienced difficulty in mastering the task because of an apparent reluctance to release one perceptual field and reconstrue the task on a higher cognitive level. It was hypothesized that were this the correct explanation, the faster learners would be more field independent on a measure of field dependence, since independence has been defined in terms of ease in releasing one's attention from the immediate perceptual field. This hypothesis was tested with 22 undergraduate subjects for whom Group Embedded Figures Test scores were correlated with the number of trials to completion on the complex learning task. A moderate but significant correlation supported the hypothesis. 相似文献

The association of left lateral eye-movement with emotionality or arousal of affect and of right lateral eye-movement with cognitive/interpretive operations and functions was investigated. Participants were junior and senior students enrolled in an undergraduate course in developmental psychology. There were 37 women and 13 men, ranging from 19 to 45 yr. of age. Using videotaped lateral eye-movements of 50 participants' responses to 15 visually presented stimuli (precategorized as neutral, emotional, or intellectual), content and statistical analyses supported the association between left lateral eye-movement and emotional arousal and between right lateral eye-movement and cognitive functions. Precategorized visual stimuli included items such as a ball (neutral), gun (emotional), and calculator (intellectual). The findings are congruent with existing lateral eye-movement literature and also are additive by using visual stimuli that do not require the explicit response or implicit processing of verbal questioning. 相似文献

28 older women participating in an exercise program were compared to 30 older women not participating in an exercise program on two behavioral measures. There were no significant main effects for participation-nonparticipation in an exercise program. Significant main effects were found, however, for each of three social variables. 相似文献

This paper offers a critique of the prevailing epistemological assumptions which undergird modern Pastoral Care and Counseling education. By drawing upon emerging insights in Transpersonal Psychology and Consciousness disciplines, along with the ontological perspectives of Martin Heidegger and John Macquarrie, the attempt is made to reclaim the modes of knowing of William James and Anton Boison. This paper includes practical and concrete examples of how one supervisor is attempting to put a new paradigm into practice. 相似文献
