EEG alpha activity was monitored during word presentation in a single trial cued-recall task. Initial post-word changes in alpha were related to a dimension of word meaning (arousal-neutral) while subsequent alpha asymmetry was a function of encoding instructions (verbal or visual). Initial bilateral reductions in alpha were associated with increased recall, but subsequent asymmetry in alpha was not. The results suggest a two stage pattern of cortical activation associated with memory storage processes. 相似文献

It has been suggested recently that there are two fundamentally distinct types of auditory sequence perception in man: (1) hofistic pattern recognition (HPR), operating for component item durations from a few milliseconds up to about 200 msec; and (2) direct identification of components and their order (Direct ICO), requiring verbal encoding of names for constituent sounds and requiring item durations roughly 200 msec and above for extended sequences. The present study, using only the very first judgments from 795 untrained participants presented with recycled three-item sequences, provided data consistent with this dichotomous formulation. In addition, it appeared that separate bursts of a noise band generated on-line were treated as different components in HPR and could not be used for sequence matching; “frozen” noise bursts having identical microstructure were treated as the same component and permitted HPR. On-fine noise bursts permitted Direct ICO, with naming based on long-term spectral characteristics of noise. 相似文献

Four studies (total n= 469) examined correlates of loneliness in order to explore explanations for the persistence of loneliness among college students. Self-report and attitude scales, ratings of others following dyadic interactions, and self and other ratings at two points during an extended period of group interactions indicated that lonely students (a) rated themselves more negatively and reported deficits in social skills and self-concept, (b) rated specific others and people-in-general more negatively and were more alienated and externalized, (c) expected others to rate them negatively, but (d) in general were not differentially rated by others except in the initial phase of group interactions and by lonely others following dyadic interactions. Results suggested that loneliness may be perpetuated by its cognitive and affective concomitants, with some evidence for gender differences, whereas inconclusive evidence was found regarding responses of others to the lonely person. 相似文献

The social network paradigm is a construct for analysis of social relationships developed in social anthropology. As a concept, however, the social network paradigm has undergone parallel development in several academic and clinical streams of research and practice. Basic research and clinical questions are presented for further exploration in the development of the paradigm.This work was supported in in part by grant #AA03506-01AL from the national Institute of Alcohol Abuse and Alcoholism, awarded to the University of California, Irvine, Department of Psychiatry. 相似文献

Three male college seniors were asked to drink beer at their normal rate in a simulated tavern setting. Each was paired with a confederate, also a male college senior, in an ABACA single subject design. In the baseline conditions, the confederate matched the drinking rate of the subject. Baseline and all subsequent conditions were continued in 1-hr sessions until a stable drinking rate was achieved. In Condition B, the confederate drank either one third more or one third less than the subject's baseline rate. In Condition C, the direction was reversed. All three subjects closely matched the confederate's drinking rate, whether high or low. All subjects reported they were unaware of the true purpose of the study. 相似文献

Kendall's rank order test for association between two variables is generalized to the case where the total sample is made up of several subgroups and the data on one or both variables consist of the rank order within each subgroup. The test involves no assumptions concerning scales of measurement, shapes of distributions, or relative level of excellence or amount of variability of the different subgroups. Two empirical examples indicate that the normal approximation to the exact test of significance can be considered adequate for most practical situations. Special consideration is given to the case of tied ranks. If ties occur in but one variable within any given subgroup, only a slight modification in procedure is needed. Extensive ties in both variables within subgroups lead to difficulties in determining the appropriate correction for continuity. 相似文献

Social scientists have long emphasized the reciprocal relationship between family and religion in society. Yet the family therapy literature is virtually devoid of consideration of religious variables in family life and function. Four major psychosocial aspects of religion in family life are discussed: sacralization, coalitions with the supernatural, religious conflict as a projection of family conflict, and family conflict as a projection of religious conflict. Clinical issues presented include: family therapy in religious and secular contexts, family religious expectations and transference, therapist religious countertransferences, religious identification in family therapy, and family therapy in different degrees of congruence or difference in religious orientation between the family and the therapist. The family therapist must learn how to correctly interpret and appropriately respond to religious issues as they appear in family life and family therapy. 相似文献

The phenomena of prismatically induced “visual capture” and adaptation of the hand were compared. In Experiment 1, it was demonstrated that when the subject’s hand was transported for him by the experimenter (passive movement) immediately preceding the measure of visual capture, the magnitude of the immediate shift in felt limb position (visual capture) was enhanced relative to when the subject moved the hand himself (active movement). In Experiment 2, where the dependent measure was adaptation of the prism-exposed hand, the opposite effect was produced by the active/passive manipulation. It appears, then, that different processes operate to produce visual capture and adaptation. It was speculated that visual capture represents an immediate weighting of visual over proprioceptive input as a result of the greater precision of vision and/or the subject’s tendency to direct his attention more heavily to this modality. In contrast, prism adaptation is probably a recalibration of felt limb position in the direction of vision, induced by the presence of a registered discordance between visual and proprioceptive inputs. 相似文献
