Two experiments explored variation in the alerting process across age and warning interval as well as the effects of alertness on subsequent processing. Experiment 1 obtained alertness functions for a group of 5-year-olds, 8-year-olds, and adults. Results revealed strong age differences in speed of alerting and in maintenance of alertness over a 1-sec interval. Five-year-olds alerted more slowly than older groups and sustained optimal alertness less well. Both groups of children showed more variability in alerting functions compared with adults. Experiment 2 examined the degree to which age differences in processing speed were attributable to differential speed and maintenance of alerting. Masking functions obtained across variations in the alerting interval revealed that when level of alertness was optimal in both 5-year-olds and adults, minimal age differences in processing speed were observed. During short, nonoptimal alerting intervals, speed of processing in adults was faster than in 5-year-old children. The pattern of results across studies suggested that alertness can fluctuate over time in young children, that level of alertness affects subsequent perceptual processing speed, and that developmental variation in speed and maintenance of alertness can partly explain observed age differences in processing speed. The potential role of alertness in more complex cognitive tasks is discussed. 相似文献

The efficacies of Western and Chinese medicine have been under debate for a long time, and the whole issue still raises questions for the contemporary world. The article emphasizes the humanistic approach as well as the scientific method of the early Protestant medical missionaries to China, so as to give a more comprehensive scope to understand their historical roles and practices in a cross‐cultural context. The authors also wish to call for a global readership to further discuss this historical legacy with regard to the reception of Christianity in contemporary China and other East Asian countries. 相似文献

Five-year-olds, as compared to adults, have displayed a striking constraint on short-term recognition memory for briefly presented visual information. In the present study, a recall paradigm was also examined to test the generality of this constraint. Additionally, we examined the possibility that forced verbal report might differentially enhance children's performance. Evidence of improved performance in children would suggest that a verbal encoding strategy, used by adults only during the recognition task, is activated in children in a recall task. Though recall memory performance of young children did surpass recognition memory levels, the same was true for adults with the relative adult-child difference remaining constant across conditions. It was concluded that processes other than verbal labeling (e.g., buffer storage, organization, retrieval) are probably more responsible for age differences in immediate memory performance than labeling, per se. 相似文献

An attempt was made to specify whether previously reported limitations on young children's full-report capacity lay in a smaller amount of available information, in a shorter trace duration of information in visual information storage (VIS), or in poorer coding of information into permanent storage. Five- and 8-year-olds and adults were shown an eight-item array of figures. followed at varying intervals by an indicator signaling the subject to report the figure to which the indicator had pointed. The effects of three levels of familiarity or “labelability” were examined. While no age differences were revealed in amount of information available nor in the trace duration of information in VIS, strong age differences emerged in coding of information into permanent storage. Data on latency to verbal labeling and familiarity suggested that verbal labeling could not account for the age trends. Rather, the differences seemed to lie in the use of organized visual coding and rehearsal strategies by adults and their relative lack of use by children. 相似文献

While there is a growing literature on global managers, most studies in this area have not built upon the wealth of existing knowledge in the field of management development. This study examines if established theoretical constructs will account for managerial performance in complex global jobs and investigates the utility of each of these approaches. Boss performance ratings were correlated with manager's self-ratings on measures of personality, role skill, learning capability, business knowledge, and international experiences for 194 managers--half with global responsibilities and half with domestic responsibilities. Skill in the roles of leader and decision maker were significantly related to performance ratings for managers in high and low global complexity jobs. Learning skills, additional role skills, and international business knowledge were uniquely, albeit modestly, related to performance ratings for managers in globally complex jobs. A development framework is proposed that integrates the various theoretical constructs. Specifically, personality and international experience are considered as antecedent to skill rather than as predictors of global performance. Financial resources are not the problem. We have the money, products, and position to be a dominant global player. What we lack are the human resources. We just don't have enough people with the needed global leadership capabilities. 相似文献

Traditional explanations of reading disability (e.g., perceptual, memory, and phonetic receding deficits) have encountered logical difficulties and substantial empirical disconfirmation. An alternative conceptualization of the nature of reading disability is proposed. Disabled readers are hypothesized to suffer a fundamental problem in acquiring word knowledge and word processing skills. Poor decoding skills prevent them from developing sophisticated reading comprehension skills. From this perspective, the cognitive deficits of disabled readers result from failure to acquire and generalize complex processing skills originally mastered through reading experience. Recent research of the author and of others relating to these issues is discussed. 相似文献

The view of competence proposed by Waters and Sroufe remains faithful to a kind of theorizing about human personality which emphasizes its unitary and universal properties. Developments in other areas of inquiry, however, are redirecting theoretical efforts toward a more pluralistic and contextualistic view of human nature and development. Implications for future theories of development are discussed. 相似文献
