Consideration is given to recent behavioural approaches to the management of anxiety responses. Emphasis is placed on the importance of both the physiological and cognitive characteristics of the anxious patient. It is argued that biofeedback may be a useful tool to facilitate changes in the physiological and cognitive systems. Finally, three case studies are presented and discussed in relation to the multimodal approach. 相似文献

Past research based on the McCollough effect and efficacy of chromatic cues in stereopsis suggests that color information is difficult to process binocularly as compared to form information. This study evaluates this proposition using a reaction time paradigm. Subjects decided whether two simultaneous visual stimuli were the same in shape or color. With presentation to the same eye, color reaction times led shape latencies. Presenting one target to one eye and one to the other slowed color times. Delaying one target by 500 msec yielded dichoptic and monoptic color decisions faster than shape. The results are related to the relationships of color and contrast pathways and possible differences in binocular rivalry. 相似文献

Kaiser's measure of sampling adequacy is applied to a special Spearman matrix and a specialq-cluster generalization. The result supports the contention that the measure should be no less than .5 for data to be appropriate for factor analysis.The research reported in this note was supported in part by the Program in Applied Mathematics and Statistics, National Science Foundation, and by the National Institute of Education, Department of Health, Education, and Welfare. 相似文献

A NEURAL SYSTEM FOR ERROR DETECTION AND COMPENSATION 总被引:26,自引:0,他引:26

Abstract— Humans can monitor actions and compensate for errors. Analysis of the human event-related brain potentials (ERPs) accompanying errors provides evidence for a neural process whose activity is specifically associated with monitoring and compensating for erroneous behavior. This error-related activity is enhanced when subjects strive for accurate performance but is diminished when response speed is emphasized at the expense of accuracy. The activity is also related to attempts to compensate for the erroneous behavior. 相似文献

Analyses of multinomial mixture distributions: new tests for stochastic models of cognition and action 总被引:3,自引:0,他引:3
Mixture distributions are formed from a weighted linear combination of 2 or more underlying basis distributions [g(x) = sigma j alpha j fj(x); sigma alpha j = 1]. They arise frequently in stochastic models of perception, cognition, and action in which a finite number of discrete internal states are entered probabilistically over a series of trials. This article reviews various distributional properties that have been examined to test for the presence of mixture distributions. A new multinomial maximum likelihood mixture (MMLM) analysis is discussed for estimating the mixing probabilities alpha j and the basis distributions fj(x) of a hypothesized mixture distribution. The analysis also generates a maximum likelihood goodness-of-fit statistic for testing various mixture hypotheses. Stochastic computer simulations characterize the statistical power of such tests under representative conditions. Two empirical studies of mental processes hypothesized to involve mixture distributions are summarized to illustrate applications of the MMLM analysis. 相似文献

The birth and hospitalization of a preterm infant are stressful and emotionally demanding experiences for parents. The Clinical Interview for Parents of High-Risk Infants (CLIP) is a semistruc tured clinical interview that may be used as a one-time assessment or as a cornerstone for ongoing psychosocial work with parents. The interview assesses early parental adaptation and alerts the clinician to areas of concern as identified by the parents. The interview enables parents to consolidate emotionally their experiences relative to the infant's high-risk status. The CLIP has utility both for planning psychosocial care in the intensive care nursery, and for discharge preparation. The rationale underlying the design of the CLIP is presented, the interview is described, and clinical applications are discussed. 相似文献

We demonstrate ways to incorporate nondeterminism in a system designed to formalize the reasoning of agents concerning their abilities and the results of the actions that they may perform. We distinguish between two kinds of nondeterministic choice operators: one that expresses an internal choice, in which the agent decides what action to take, and one that expresses an external choice, which cannot be influenced by the agent. The presence of abilities in our system is the reason why the usual approaches towards nondeterminism cannot be used here. The semantics that we define for nondeterministic actions is based on the idea that composite actions are unravelled in the strings of atomic actions and tests that constitute them. The main notions used in defining this semantics are finite computation sequences and finite computation runs of actions. The results that we obtain meet our intuitions regarding events and abilities in the presence of nondeterminism. 相似文献
