This experiment was designed to determine whether isolation during two developmental periods would contribute to differences in home-cage agonistic behavior and whether altered reactivity was a mediating variable. While early isolation (16–41 days) was shown to have a significant and sustained impact on agonistic behavior, isolation during a later developmental period (41–68 days) did not result in altered occurrences of agonistic behavior. While isolation did result in increased reactivity to both footshock and dorsal tactile stimuli, the pattern of these data suggested that hyperreactivity to tactile stimulation was not a satisfactory account of the increased agonistic behavior of rats raised in isolation. 相似文献

对36个国家8007名大学生的生活满意度进行了问卷调查。多层线性模型分析(HLM)的结果表明:(1)积极情感体验、自我满意和社会关系满意度能显著正向预测生活满意度,而消极情感体验能显著负向预测生活满意度;(2)情感体验、自尊和社会关系满意度对整体生活满意度的预测力存在着显著的国家间差异;(3)个人主义———集体主义是导致生活满意度水平国家间差异的重要因素,同时也对自尊与生活满意度的相关有显著预测作用,但它并不影响情感体验和社会关系满意度与整体生活满意度之间的关系。 相似文献

The present study investigated self-face perception in 12-month-old infants using the morphing technique. Twenty-four 12-month-old infants participated in both the main and control experiments. In the main experiment, we used the participant’s own face, an unfamiliar infant’s face (age- and gender-matched), and a morphed face comprising 50 % each of the self and unfamiliar faces as stimuli. The control experiment followed the same procedure, except that the self-face was replaced with another unfamiliar face. In both experiments, two of these stimuli were presented side by side on a monitor in each trial, and infants’ fixation duration was measured. Results showed that shorter fixation durations were found for the morphed face compared with the self-face and the unfamiliar face in the main experiment, but there were no significant preferences for any comparisons in the control experiment. The results suggest that 12-month-old infants could detect subtle differences in facial features between the self-face and the other faces, and infants might show less preference for the self-resembling morphed face due to increased processing costs, which can be interpreted using the uncanny valley hypothesis. Overall, representations of the self-face seem to a certain extent to be formed by the end of the first year of life through daily visual experience. 相似文献

Students who fail to acquire foundational literacy skills during preschool are more likely to read below grade level average in elementary school and are at a heightened risk for future school failure, poverty, early mortality, and crime. The purpose of this study was to compare the effects and maintenance of and preference for paired kinesthetic movements (KM) to a traditional drill (TD) procedure on letter–sound correspondence and word recognition with 6 preschool children. In 6 of 11 evaluations, participants mastered the KM set in substantially fewer intervention sessions than the TD set. In 5 of 11 evaluations, participants mastered the KM and TD sets with little differentiation between the number of intervention sessions. No participant mastered the control set. Maintenance data demonstrate a higher number of correct responses for the KM condition across all weeks. Preference varied across participants and was not always consistent with the more effective intervention. 相似文献

This review is set to present the gist of the theoretical account of consciousness recently presented by Christof Koch and pose a couple of questions instigated by this account. The expected answers to these questions would hopefully help to advance our understanding of the basic nature of the conscious mind. 相似文献
