Motor and galvanic skin potential (GSP) activity were investigated during the conditioning, extinction, and reconditioning of motor responses under a differential reinforcement of low rate (DRL) schedule of reinforcement. Interresponse time (IRT) distributions for motor responses during conditioning and reconditioning gradually stabilized at a peak just beyond the minimal IRT required for reinforcement. Few unreinforced motor responses and "bursts" of motor responses were observed during conditioning and reconditioning. Relative to conditioning and reconditioning, extinction effected larger IRTs and smaller GSP amplitudes. GSP amplitudes were greater for unreinforced than for reinforced motor responses during conditioning and reconditioning. However, GSP amplitudes associated with the unreinforced extinction responses were smaller than either the reinforced or unreinforced responses during conditioning and reconditioning. 相似文献

This paper describes how a particular content can be ascribed to verbal group work with psychiatrically hospitalized children. This focus can then provide the basis for psychotherapeutic intervention in which resistance and transference are interpreted while underlying conflicts are uncovered and worked on. The theme of the group, health issues and sexuality, was derived from the children's expressed needs on the unit. The use of psychotherapy as a basis for subsequent education about these health issues is discussed. Also described is the way in which the verbal medium was used in conjunction with other unit procedures. 相似文献

Forty-one female and 61 male assistant professors, of whom 46% were involved in dual-career relationships, responded to a mail questionnaire that assessed (1) androgyny; (2) satisfaction at work, home, and in their personal life; (3) stress at work, home, and in their personal life. A 2×2×2 analysis of variance was conducted to evaluate the effects of relationship status, androgyny, and sex of subject. The results indicated that being androgynous was associated with increased work stress, but simultaneously increased personal satisfaction. A significant interaction between androgyny and relationship status demonstrated that androgynous dual-career persons reported highest personal satisfaction; androgynous nondual-career persons reported highest work satisfaction. Dualcareer status increased personal and work stress, as well as relationship satisfaction. The importance of considering each person's specific life situation when evaluating androgyny as a positive or negative attribute is discussed. 相似文献

As a parallel to the dual decoding concept for processing of written language we proposed that phonological encoding does not necessarily occur in writing and that the phonemic and graphemic subsystems can be independent on the one-word level. This hypothesis was tested by comparing oral and written performance in a picture-naming task in Broca's and Wernicke's aphasics. In addition, the residual tacit knowledge of the orthographic properties of the names of the pictures was examined with a multiple-choice recognition task. The principal finding is that Broca's aphasics who were better in written than in oral naming showed more graphemically and semantically motivated errors than aphasics who were better in oral than in written naming, the latter producing more phonemically motivated errors. This result supports the dual encoding concept for writing on the singleword level, implying a direct route from the mental lexicon to the graphemic system in parallel with a route mediated by the phonemic system. Multiple-choice recognition was found to be superior to both oral and written performance in both Broca's and Wernicke's aphasics. 相似文献

There were no differences in lateral dominance indices between first and second languages in English-Hebrew bilinguals tested with a dichotic word test. Lateral dominance was the same for both languages regardless of when the second language was learned, how long it had been used, or how well it was known (according to a self-rating scale). In addition, the “traditional” sex differences were found where females had a significantly better overall recall performance but a significantly smaller difference in performance between the right and left ears. 相似文献

This study was desinged to determine if motor deficits in limb apraxia are task specific. Non-brain-damaged patients and apraxic and nonapraxic patients with left hemisphere damage performed language and limb apraxia tests and six motor tasks with the left hand. Contrary to previous data, no significant group differences occurred on a finger tapping task. Although task complexity or sequencing requirements affected group differences, greatest apraxic impairment was noted on a task of precise steadiness, but only when its response inhibition requirements were increased. This pattern of deficits appears to be associated with greater involvement of the premotor area in the apraxic group. 相似文献

Italian male school children, ranging in age from 7 to 10 years, were identified as at-risk children on the basis of self-reports, teacher questionnaires, and peer nominations assessing aggression, emotional instability, and pro-social behaviour. Together with a normal control sample, these children participated in two studies guided by attribtional theory. In Study 1, following teacher emotional feedback of anger or sympathy for failure, attributional inferences regarding low ability or lack of effort as the cause of that failure were rated. In Study 2, controllable and uncontrollable causes of a social transgression were given, and participants rated the anticipated anger of the ‘victim’ and their intention to withhold or reveal the cause. Strong effects for both populations that were consistent with attributional predictions were reported. In addition, differences between the inferences, expectations, and behavioural intentions of the populations were found, with at-risk children being less likely to perceive sympathy as a cue for low ability, and anticipating more anger from others following a transgression, particularly when there was a ‘good’ (i.e. uncontrollable) reason for the broken social agreement. It was contended that the results support the social-cognitive approach to the understanding of mechanisms of risk and deviancy. 相似文献
