Event-related potentials were recorded during encoding, to identify whether brain activity predicts subsequent retrieval of
spatial source information, and during retrieval, to investigate the neural correlates of successful and unsuccessful spatial
context recollection. The amplitude registered during encoding for study items that were later recognized and assigned a correct
source judgment was more positive than the amplitude for recognized items given incorrect source judgments; this difference
started 480 msec poststimulus, predominantly at central and anterior sites. During retrieval, the waveform was more positive
from 250 to 1,600 msec poststimulus when the brain had retrieved episodic information successfully than when it had failed.
These findings indicate that brain electrical activity recorded during the first presentation of an item within its context
predicts the subsequent retrieval of the specific spatial context. During retrieval, brain activity differed quantitatively
at anterior sites and qualitatively at posterior sites according to the accuracy of source memory. 相似文献

This study investigated whether illustrations facilitate story recall in preschoolers (N=58) 46 to 63 months of age. Each child was exposed to either a verbal story narrative with illustrations (Verbal and Picture condition), the narrative alone (Verbal Only condition), the narrative with uninformative illustrations (Verbal and Irrelevant Picture condition), or the illustrations alone (Picture Only condition). Children recalled the story immediately and after a 1-week delay. With increasing age, the Verbal and Picture group increasingly outperformed the other verbal groups, particularly when recalling central details conveyed by both narrative and illustrations. Performance did not vary among the three verbal groups at lower values of age, whereas the Verbal and Picture group recalled more than the other verbal groups at the older ages. Regardless of age, all verbal groups outperformed the Picture Only group, suggesting that preschoolers are unlikely to spontaneously generate a narrative from pictures alone. 相似文献

Strategic remembering emerges gradually during the preschool years. Socialization practices, specifically mother–child social interactions, might provide the foundation for the development of skills necessary for effective organization of information in memory. In the current study, 48 mothers and their 40-month-olds were engaged in the process of remembering (i.e., study and recall) categorically related picture stimuli in a laboratory context. Children’s recall was reliably predicted by the way in which mothers structured both the study and recall periods of the deliberate memory task. Specifically, maternal verbal and physical behaviors that focused on organization of items, such as sorting items into distinct groups and providing the name of a category, were most beneficial in supporting children’s memory. Moreover, some mothers employed a number of different mnemonic techniques that emphasized categorical connections among items, suggesting systematic approaches in the manner in which mothers help children to learn effective ways of remembering. 相似文献

Three hundred and thirty-five full members of the National Society of Genetic Counselors completed a survey concerning the nature of clinical supervision for genetic counseling students. Slightly over half (54.3%, n = 182) had provided clinical supervision within the past 5 years. Of those who supervised, 66.7% had 5 years or less supervision experience, and 55% had supervised 10 or fewer students. The majority became supervisors because they enjoy teaching and contributing to the profession. Common reasons for not supervising include no local graduate program, and had never been asked to supervise. Live supervision is the most prevalent student evaluation method: every supervisor reported providing one-on-one oral feedback, and 47.3% indicated that they always provide feedback immediately following a counseling session. The most frequent challenges involve students who lack technical knowledge and who fail to incorporate feedback. Training, policy, and research implications are discussed. 相似文献

Inadvertent exposure to pornography on the Internet: Implications of peer-to-peer file-sharing networks for child development and families 总被引:1,自引:0,他引:1
A request from the National Academies to prepare a presentation for a Workshop on Non-Technical Strategies to Protect Youth from Inappropriate Material on the Internet occurred before much was known about children, youth, and the Internet. The author's strategy was to investigate websites that cater to children and adolescents. The developmental issue of consumer socialization was raised by a visit to the Disney website. In contrast, the developmental issues of sexuality, aggression, and intergroup relations were raised by visits to chat rooms hosted by two different Internet Web portals. Examination of existing research literature, in conjunction with visits to the websites, led to the following conclusions: (1) Many parents are aware of the problems of making children the targets of commerce; however, they are quite unaware of the kind of social and cultural worlds young people are creating online. (2) Children and adolescents are not simply the targets of adult Internet creations; they are active participants in creating their own cybercultures, for example, in teen chat rooms. (3) The nature and norms of these cultures can be very much influenced by adult rules, regulations, and participatory monitoring. (4) The important developmental issues raised by this new medium are not unique to the Internet. For example, each psychosocial phenomenon from consumerism to sexuality to aggression has important manifestations in the culture at large. 相似文献

Neurological conditions affect sustained attention, but the effects of modality and interactions with test order have not been examined. In a 2 x 2 (Order x Modality) design using 54 children with chronic epilepsy, performance was compared on an auditory measure (modified Seashore Rhythm Test) versus a visual measure of attention (modified Conners' Continuous Performance Test). Auditory scores were worse than visual, F(1, 52) = 98.93, p<.001, but there was no order effect or interaction (p>.05). Implications for assessment and intervention are discussed. 相似文献
