Four boys with autistic-like behavior were treated for self-stimulatory behavior with three different treatment procedures—time-out, differential reinforcement of other behavior (DRO), and overcorrection. All four boys showed a rapid response to the overcorrection procedure. Three boys demonstrated some evidence of decrement in responding with time-out. During the DRO procedure, one showed a modest decrease, two showed no change, but one exhibited a consistent increase in responding under this condition. A multiple baseline applied to one of the subjects failed to reveal any generalization of suppression from one setting to another. A strong but not perfect relationship was found between a frequency and a duration measure of self-stimulation. There was some evidence of negative side effects for one boy during overcorrection and for another during time-out. None of these negative side effects was enduring. There was also some indirect evidence that overcorrection facilitated appropriate play. 相似文献

A rating instrument was developed to assess the personality functioning of problem adolescents who have a brief history of official delinquency. Subjects were 186 residents at a short-term diagnostic detention facility. The instrument that emerged from a factor analysis was tested for reliability, validity, and cross-situational generality. Two major orthogonal factors emerged, Apathy-Withdrawal (I) and Anger-Defiance (II). Each factor was found to be congruent with the corresponding dimension on behavior rating instruments that had previously yielded two orthogonal factors and that had been shown to be relevant to a large number of psychological and educational issues. Significant correlations between the factors and a series of global ratings measuring behavior and measures indicative of the frequency and seriousness of official delinquency provided further evidence of construct and discriminant validity as well as evidence of cross-setting consistency of personality functioning. 相似文献

Three experiments examined memory for metaphorical sentences. No differences between metaphors and nonmetaphorical equivalents (e.g.,The ivy cuddled up to the window vs.The ivy grew up to the window) in the number of correct recalls or recognitions were found. There was, however, a significant trend for recall errors that were meaning-preseving to be less metaphorical than the input sentence. The results supported hypotheses that metaphors and nonmetaphors are equally easy to remember and that the stored memory representation does not distinguish whether its antecedent linguistic input was metaphorical or not.This research was supported by Grant MH 28493-01 from NIMH and by a grant from the Kansas State University Bureau of General Research.Some of the data were reported at the Meeting of the Psychonomic Society, Denver, November 1975. 相似文献

The desirability of control 总被引:4,自引:0,他引:4
The psychological construct of desirability of control was related to several theoretical statements (e.g., Kelley, 1971; White, 1959) and areas of current research (e.g., Glass & Singer, 1972; Deci, 1975) in psychology. A scale designed to measure individual differences in the general level of motivation to control the events in one's life was presented. The Desirability of Control Scale was found to have substantial internal consistency (.80) and test-retest reliability (.75), as well as discriminant validity from measures of locus of control (Rotter, 1966) and social desirability (Crowne & Marlowe, 1960). The results of an illusion of control study (cf. Langer, 1975) provided construct validation: only subjects high in the desire for control displayed a belief in personal control over chance outcomes. Construct validation was also provided from studies on learned helplessness and hypnosis. The practical, as well as theoretical, value of the instrument was discussed.This research was facilitated by National Science Foundation grant BNS78-08834 to Harris Cooper. 相似文献

Some comparative experiments on the dichoptic induction of the movement aftereffect (MAE) contingent on color and the MAE contingent on orientation are reported. Colorcontingent movement aftereffects could be evoked only when the eye which had viewed color during adaptation also viewed color during test sessions. When the apparent color of the test field was changed by binocular color rivalry, contingent movement aftereffects (CMAEs) appropriate to the suppressed color were reported. After dichoptic induction of the orientation-contingent MAE, aftereffects could be obtained whether the eliciting gratings and stationary test fields were presented together to either eye alone or were dichoptically viewed. 相似文献

A range of variants of the Schröder staircase was generated by computer, giving quantifiable changes of perspective and the option of adding appropriate texture to the steps of the staircase. Increases in perspective and the addition of texture gradients led to increases in the proportion of viewing time during which the percept appropriate to the perspective was reported. It is suggested that this might be a useful method of studying the processing of depth information. 相似文献

This study investigated whether an observed inverse relationship between self-stimulation and learning in autistic children is due to a physical inability of the subject to use the same body part for self-stimulation and task responding, or whether self-stimulation “distracts” the subject from task responding. Four actively self-stimulating autistic children were taught two discrimination tasks; one required a response that physically interferred with their self-stimulation; the other did not. Results were: (a) all subjects responded similarly across both tasks; (b) the three subjects with higher mental age scores learned both tasks without external suppression of self-stimulation; and (c) none of the subjects showed an inverse relationship between self-stimulation and learning. The study demonstrated that elimination of self-stimulation is not a necessary prerequisite for the acquisition of a new behavior in all autistic children. 相似文献

In deciding that two items come from the same category, subjects were delayed if the items were presented as a word and a picture, as compared with two words or two pictures. Subjects were not delayed if the items were not to be compared. Hence, the delay appears to occur during the retrieval and comparison of know ledge about the items, not during their perceptual analysis. The results suggest that there are two distinct codes involved in the categorization of words and pictures, rather than a single code. 相似文献
