An experiment was conducted to compare the relative effectiveness of a value confrontation procedure and a procedure based on verbal operant conditioning in enhancing career development attitudes and increasing the frequency of information-seeking behavior in rural adolescent males. Ninety subjects were identified as internally controlled or externally controlled based on their locus of control scores and then randomly assigned to one of the two experimental treatment groups or a control group. The value confrontation procedure involved developing an awareness of self-dissatisfaction about one's career planning and relating this self-dissatisfaction to the importance one gave to the values logical and responsible. These values had been identified empirically in this study as having a relationship to career planning. The reinforcement counseling treatment involved the interpretation of individual career maturity data followed by the verbal operant conditioning of responses indicative of career maturity. Post tests administered 7 weeks after the treatments showed that the value confrontation procedure resulted in significantly greater frequency of information seeking for internally controlled subjects when compared to the reinforcement counseling and control procedures. No treatment was significant in increasing the maturity level of career development attitudes.  相似文献

Discrimination learning set performance was examined in preschool children as a function of age and number of trials per problem. Subjects 3, 4, 5, and 6 years old were trained over three 72-trial sessions. Half of the children at each age were given problems three trials in length, and half received 12-trial problems. As predicted, younger children (3 and 4-year-olds) performed significantly better for 12 than for three trials per problem, whereas no differences in performance were evident for older children. Response pattern analyses revealed that younger children, especially those receiving less exposure within problems, produced a higher proportion of stimulus alternation and position determined response sequences than did older children. These results contradict the commonly held assumption that learning set acquisition is simply a function of the total number of trials presented and indicate that the amount of exposure to individual problems is a factor in problem solution for young human subjects.  相似文献

The effects of methylphenidate on the behavior and teacher interactions of a 9-year-old hyperactive female were analyzed. Observations of the subject's task-related and disruptive behaviors and of interactions between the subject and her classroom teacher were made when the subject received the active drug and an inert placebo. Teacher's ratings of the subject's classroom behavior and measures of her academic performance were also obtained. Results showed that when the subject was receiving methylphenidate she engaged in task-related activities a greater percent of the time, had a higher percent of teacher interactions that were instructional in quality, and received lower behavior ratings by the teacher than when she was receiving a placebo. The results suggest that the use of medication may enable the hyperactive child to profit both behaviorally and academically.  相似文献

Rats of the Maudsley Reactive and Maudsley Non-reactive strains were given 25 trials of escape-avoidance conditioning after exposure to inescapable shock. Prior shock exposure (PSE) did not affect avoidance or escape latencies, but decreased the number of avoidances made by the Maudsley non-reactive animals and increased the number of their failures to escape. The results are interpreted as demonstrating an interference with the classical conditioning of a conditioned emotional response, through a reduction in the information content of the CS following PSE. The strain differences are interpreted as due to the non-reactive animals being especially sensitive to PSE.  相似文献

Effective communication in aphasia depends not only on use of preserved linguistic capacities but also (and perhaps primarily) on the capacity to exploit alternative modalities of communication, such as gesture. To ascertain the capacity of aphasic patients to use gesture in their spontaneous communication, informally structured interviews were conducted with two Wernicke's aphasics and two Broca's aphasics, as well as with four normal controls. The performances of the patient groups were compared on the physical parameters of gesture, the points in the communication where gestures occurred, and several facets of the semantics and pragmatics of gesture. Generally speaking, the gestures of the aphasics closely paralleled their speech output: on most indices, the performance of the Wernicke's aphasics more closely resembled that of the normal controls. Wernicke's aphasics differed from normals in the clarity of their language and gestures: While individual linguistic units were often clear, the relation among units was not. In contrast, the Broca's aphasics equaled or surpassed the normal controls in the clarity of their communications. The results offer little support for the view that aphasic patients spontaneously enhance their communicative efficacy through the use of gesture; these findings can, however, be interpreted as evidence in favor of a “central organizer” which controls critical features of communication, irrespective of the modality of expression.  相似文献

This paper reports two studies which support the prediction derived from Hershenson's (Journal of Counseling Psychology, 1968, 15, 23–30) life-stage vocational development model that average scores on Self-differentiation (worker self-concept and motivation) would exceed those on Competence (work habits, skills, and interpersonal relations), which in turn would exceed those on Independence (appropriateness and crystallization of vocational goals). The first study involved ratings by project staff on an inner city, socially disadvantaged population, and the second study involved self-ratings by individuals who had changed occupations in midcareer. Findings are consistent with those reported by Hershenson and Langbauer (Journal of Counseling Psychology, 1973, 20, 519–521) on a population of deaf clients.  相似文献

A study is reported of neurotic patients at St. Bartholomew's Hospital, London, who were given the Eysenck Personality Questionnaire and who were rated by their doctors for prognosis and final assessment after treatment. The results indicated that those patients who had elevated psychoticism scores took longer to improve and that doctors rated them harder to treat at final assessment. It is suggested that early knowledge of patients with a poor prognosis, in the form of their Psychoticism score, might prove helpful to psychiatrists and psychologists, both for diagnosis and (primarily) for choice of appropriate treatment.  相似文献

One hundred and forty third and seventh grade children (ages 9 and 13 years) learned familiar animal terms organized and presented either hierarchically, in lists, or randomly. Following multitrial free recall of list items, subjects performed four sorting tasks with the same item set to test for transfer of the organizational principles employed in the original learning. A no-training group at each level also sorted. There was a training effect at both grade levels on the sorting tasks. Groups receiving structured presentations had essentially learned a new lexical organization for the items. As expected, older children applied the learned structures more spontaneously and more accurately than younger children in the same conditions. The importance of a transfer task in assessing changes in subjective organization is stressed.  相似文献

In a within-groups design, four obsessive-compulsive patients imagined four different types of scenes: (1) exposure to feared situations; (2) exposure to feared situations followed by engaging in ritualistic behavior: (3) engaging in ritualistic behavior without provocation; and (4) neutral situations. Each scene type was presented three times with order of presentation randomized. Beat-by-beat heart rate samples were taken during the visualization of each scene and converted to second-by-second heart rate. An examination of second-by-second heart rate for each scene type suggested that scenes involving exposure to feared situations elicited defensive responses (DR), whereas those that did not elicited orienting responses (OR). The implications of these results for compulsive behavior, the fear-reduction model and Sokolov's (1963) OR-DR model, are briefly discussed.  相似文献
