In complementary reports Robinson (1982a, b) describes how the transmission characteristics or time constants of thalamic and cortical neuron populations of the diffuse thalamocortical system (DTS) can be evaluated in human subjects. Equating these constants with the Pavlovian property of ‘strength’ it was predicted that they should relate to Extraversion and Neuroticism scores on the Eysenck Personality Questionnaire (EPQ). This prediction was confirmed and the results provide direct support for the theories of Pavlov and Eysenck. The present report describes additional results which confirm predictions relating the DTS constants to performance on the Wechsler Adult Intelligence Scale (WAIS) and on the Embedded Figures Test (EFT). An important finding was that a measure of deviation from intermediate and ‘balanced’ values of the DTS constants loads to the extent of -0.80 on the WAIS ‘memory’ or ‘attention/ concentration’ factor. More generally, the results provide further support for Pavlov's conception of brain-behaviour relationships and suggest that the DTS plays a fundamental role in determining a broad spectrum of human psychological differences including some associated with the concepts of intelligence and cognitive style. These IQ and cognitive style differences are explained as the immediate and longer-term consequences, respectively, of differences in the distribution of background cortical activity mediated by the DTS. 相似文献

Videotex is considered to be a powerful, but simple to use, computer network available for use in homes, offices, and schools. Information in the form of text and color graphics can be requested and displayed on the user’s television set. While retrieval of information is the first service provided on videotex, many other services, including electronic mail, electronic shopping, and electronic funds transfer, will be developed. However, in order to achieve the popularity predicted for videotex, a number of human factors and social problems must be solved. Research concerning some of these problems, and the role psychologists can play in their solution, is described. 相似文献

Counterconditioning is a process in which aversive stimuli that ordinarily evoke emotional or avoidance responses are paired with positive stimuli which evoke incompatible activities. Several sets of operations have been employed to induce these incompatible activities (e.g. food, Jones, 1924; relaxation. Grossberg, 1964; positive imagery, Lazarus and Abramowitz, 1962; pharmacological agents, Friedman, 1966; laughter, Ventis, 1973).Although the Counterconditioning process has been successfully applied to a wide variety of emotional disorders, special problems arise when the procedure is applied to the mentally retarded. First, because of the limitations in cognitive abilities, it is generally impossible to train the subject in either relaxation or positive imagery processes. Consequently, it is necessary to place the child in direct contact with the anxiety-inducing situation. Secondly, it is often difficult to find an anxiety-free situation which is incompatible with the anxiety-arousing situation and which can be practically implemented, particularly when the phobia involved is complex.The purpose of this paper is to describe a case whereby a phobic response of physical examination by male doctors in a 7–yr-old mentally retarded boy was extinguished by pairing the examination with an anxiety-free situation, i.e. an extremely comfortable relationship between the patient and a nurse on the ward. Previous research had indicated that parents and people who have positive relationships with a person might possibly serve as effective anxiety reducers in fear-provoking situations (Jersild and Holmes, 1935). 相似文献

This study investigates the influence of attention loading on the established intersensory effects of passive bodily rotation on choice reaction time (RT) to visual motion. Subjects sat at the center of rotation in an enclosed rotating chamber and observed an oscilloscope on which were, in the center, a tracking display and, 10° left of center, a RT line. Three tracking tasks and a no-tracking control condition were presented to all subjects in combination with the RT task, which occurred with and without concurrent cab rotations. Choice RT to. line motions was inhibited (p < .001) both when there was simultaneous vestibular stimulation and when there was a tracking task; response latencies lengthened progressively with increased similarity between the RT and tracking tasks. However, the attention conditions did not affect the intersensory effect; the significance of this for the nature of the sensory interaction is discussed. 相似文献

It was shown that a McCollough-type color aftereffect could be induced using a pair of patterns each of which contained lines of many orientations (radial lines and concentric circles). That is, the two patterns appear to be color adapted independently. The effect could simply be a new version of the McCollough effect facilitated by a tendency to fixate the centers of the patterns. Also, the size features of the displays could be used as the basis of a spatial frequency analyzer explanation. Experimental data were used to test both of these suggestions, but very little support was found for either. It was therefore suggested that the major basis of the effect was the color adaptation of “curvature analyzers.” 相似文献

We sought to compare clusters of suicidal events between two different time periods and examine the extent to which earlier clusters predict later clusters. We included data on suicides and suicide attempts from New South Wales between July 2001 and June 2012 and Western Australia between January 2000 and December 2011. Suicide attempts included admissions to hospital for deliberate self‐harm and suicides were deaths due to deliberate self‐harm. We combined data on suicides and suicide attempts and grouped them into two equal time periods. We detected clusters in each period using Poisson discrete scan statistics adjusted for socio‐economic status. We estimated the predictive values of earlier clusters on later clusters. The results showed that clusters from earlier time period had a moderate power (36%) in predicting later clusters. During the later time period, some additional cluster areas (14%) were found and some earlier cluster areas subsided (64%). Historical clusters predict 36% of the subsequent clusters, which is probably not sufficient for targeting interventions. Our study highlights the need for other strategies to detect emerging clusters, for example, up‐to‐date data. 相似文献
