This study examined (a) the links between children's overly positive perceptions about the relations with the peer group and with their best friend to subsequent behavioral, emotional, and social adjustment, and (b) whether these links are moderated by children's aggression. Using a short-term longitudinal design, the study was based on a sample of 819 4th- to 6th-graders (427 girls) from low to average SES families. Results showed that positive illusions about their social relations with classmates and with friends were related to an increase in children's peer-rated social preference and fostered the stability of children's dyadic friendships, regardless of children's level of aggression. In addition, overestimation of social competence with the peer group and overestimation of friendship quality were both related to a decrease in children's depressive feelings. Extreme overestimation as well as extreme underestimation of social competence with the peer group was also related to an increase in children's aggression. This latter result, however, was only true for children who were highly aggressive to begin with. The theoretical and practical implications of these results are discussed. 相似文献

Previous behavioral studies in Octopus vulgaris revealed lateralization of eye use. In this study, the authors expanded the scope to investigate arm preferences. The octopus's generalist hunting lifestyle and the structure of their arms suggest that these animals have no need to designate specific arms for specific tasks. However, octopuses also show behaviors, like exploration, in which only single or small groups of arms are involved. Here the authors show that octopuses had a strong preference for anterior arm use to reach for and explore objects, which points toward a task division between anterior and posterior arms. Four out of 8 subjects also showed a lateral bias. In addition, octopuses had a preference for a specific arm to reach into a T maze to retrieve a food reward. These findings give evidence for limb-specialization in an animal whose 8 arms were believed to be equipotential. 相似文献

This study examined aggressive, depressed, and aggressive–depressed childrenr's peer relations from the children's own and from their peers' perspective. Participants were 819 fourth through sixth graders (50.2% girls) who were assessed twice during the same school year. Measures included children's aggression and depression, self-rated and peer-rated social acceptance, number of reciprocal friends, and self-rated and friend-rated friendship quality. Analyses revealed different patterns, depending on the perspective considered. Depression but not aggression was significantly related to difficulties with the peer group and with dyadic friends from the children's own perspective, whereas the opposite pattern was found according to the peers' view. The co-occurrence of aggression and depression entailed significant difficulties with peers regardless of perspective. The implications of these results for the links between children's aggression and depression and their interpersonal relationships are discussed. 相似文献

As people get older, they experience fewer negative emotions. Strategic processes in older adults' emotional attention and memory might play a role in this variation with age. Older adults show more emotionally gratifying memory distortion for past choices and autobiographical information than younger adults do. In addition, when shown stimuli that vary in affective valence, positive items account for a larger proportion of older adults' subsequent memories than those of younger adults. This positivity effect in older adults' memories seems to be due to their greater focus on emotion regulation and to be implemented by cognitive control mechanisms that enhance positive and diminish negative information. These findings suggest that both cognitive abilities and motivation contribute to older adults' improved emotion regulation. 相似文献

During their 3rd week of life, 73 Octopus bimaculoides were observed to test whether discrete behaviors could be grouped reliably to reflect dimensions of temperament. Frequencies of behaviors during Week 3 were subjected to principal-components analysis (PCA), resulting in 4 components (active engagement, arousal/readiness, aggression, and avoidance/disinterest) that explain 53% of the variance. Levels of temperamental traits were then evaluated for 37 octopuses using composite scores at 3 time points across the first 9 weeks of life. Profile analysis revealed significant change for the testing group as a whole in trait expression levels from Week 3 to Week 6. Results also suggest a significant effect of relatedness on developing temperamental profiles of octopuses. Discussion focuses on how results apply to the life history of O. bimaculoides and what temperament can reveal about adaptive individuality in a protostome. 相似文献

Previous studies have found that, when remembering, older adults often rely more on schematic knowledge than do younger adults. We replicated this finding when participants were induced to review the facts of the event; furthermore, neuropsychological correlates suggested that this age-related increase in schema reliance is associated with declines in reflective processes. In addition, when they were induced to focus on their feelings and reactions when reviewing an event, both older and younger adults' later memory of the event was strongly affected by their schematic knowledge. 相似文献

In this paper I will discuss the case of an older male patient, Michael, and that of a little boy, Daniel. In both cases the archetypal image of a roaring lion has interesting clinical implications. However, the symbol of the lion had a totally different meaning for each patient as the case material will demonstrate. 相似文献

Three experiments were performed to evaluate the influence of active and passive limb movements on adaptation to visual displacement. Over a wide frequency range (0·5-1·25 Hz) with constant amplitude, 30°, significant adaptation was achieved with active and passive movements. When arm movement frequency was constant at 1·0 Hz but amplitude of movement was varied, less adaptation was achieved for both active and passive movements than when amplitude was held constant. Even at a frequency above that of most naturally occurring limb movements, 1·67 Hz, and with variable amplitude motion, significant adaptation was achieved with active and passive limb movements. These findings emphasize the importance of visual-proprioceptive discordances for adaptation to visual displacement when only sight of the hand is permitted. Significant differences did not appear between the active and passive movement conditions in any of the experiments. 相似文献
