The purpose of this study was to evaluate the effectiveness of a participative management (self-management) procedure directed toward increasing the frequency of positive interactions between direct-care staff and group home residents. A component of the self-management procedure, goal setting, was also evaluated. This study took place in two group homes housing a total of 16 male and female adults with moderate to mild mental retardation. Ten direct-care staff served as subjects. It was found that self-management produced an increase in the frequency of positive interactions of staff and residents, but did not produce changes in other behaviors being measured (e.g., negative interactions, self-stimulation, etc.). Goal setting did not result in changes in positive interactions or other target behaviors. Reasons for the different results of self-management versus goal-setting are discussed and further research is suggested.  相似文献

In his theorizing about self-actualization, Maslow speculated that physical ability and physical self-confidence were two aspects of cooperative dominance which were associated positively with actualization. These aspects of dominance bear close resemblance to the Perceived Physical Ability (PPA) and the Physical Self-Presentation Confidence (PSPC) dimensions of the Physical Self-Efficacy (PSE) Inventory. Accordingly, the PPA and PSPC scores of undergraduate men and women were correlated with their scores on the Personal Orientation Inventory (POI), a popular measure of actualization, to test Maslow's hypotheses. The results showed that, contrary to Maslow's claims, PPA is not a positive correlate of self-actualization. However, strong support was found for Maslow's contention that high-PSPC individuals are more likely to be actualizing than low-PSPC people. Also, Maslow's hypothesis that actualizers are high in global sensation seeking (SS) was tested. The data indicated that only male actualizers were high in various aspects of SS, but female actualizers were not. Multiple regression analyses revealed further that both SS and PSPC are primary contributors to POI for men, but only PSPC contributes significantly to POI for women. Discussion focused on the reasons why research findings showing that increases in physical fitness lead to increases in self-esteem cannot be used to support the view that physical fitness and actualization are linked positively.  相似文献

Regional cerebral glucose metabolism in aphemia: A case report   总被引:1,自引:0,他引:1  
Local cerebral metabolism was determined in a patient suffering aphemia following cerebral infarction using the 18FDG-PET technique. The syndrome was characterized by profound ictal nonfluency with sparing of other language functions. Speech subsequently improved so that content and grammar were appropriate but mild dysprosody persisted. Conventional CT showed no lesion of the left hemisphere while PET revealed a discrete focus of hypometabolism on the left which partially resolved on serial studies. The metabolic lesion could be localized to the region of the inferior precentral gyrus and the adjacent subcortical space.  相似文献

Two experiments examined whether individuals who ascribe the disparity in the performances of two actors to situational constraints adequately adjust their dispositional inferences to reflect their own perceptions of causality. Using the quiz-game format of L. D. Ross, T. M. Amabile, and J. L. Steinmetz (1977, Journal of Personality and Social Psychology, 35, 485–494), the effects of the subjects' awareness of the role-determined, self-presentation advantage of the questioner on their dispositional inferences concerning the quiz-game participants are noted. It is hypothesized that subjects who indicated full awareness of the determining force of the situation would nevertheless draw more favorable dispositional inferences about the questioner than about the contestant. The prediction is confirmed. Although the situationally aware subjects rate the questioner and contestant more similarly than do the other subjects, they still rate the questioner higher in knowledge, memory, and education. The results of Experiment 2 indicate that increasing the salience of the subjects' assessment of the situational advantage of the questioner does not eliminate the disparity. It is proposed that the fudamental attribution error represents more a failure to adjust trait inferences for causal attributions than a misperception of causality. Implications concerning the relationship between knowledge of causality and social judgment and the utility of the distinction between “perceived causality” and “higher order causal inferences” are discussed.  相似文献

Vietnam veterans have had a high incidence of substance abuse, resulting from attempts to control posttraumatic symptoms. Their recovery from drug and alcohol dependency has meant involvement in treatment for resolution of posttraumatic symptoms. The author found that the addition of a short-term educational-therapeutic group experience, focusing on the symptoms of posttraumatic stress disorder, was helpful for the participants. They worked-through important war-related experiences via the following phases: (1) Breaking through detachment and establishing control over disruptive symptoms, (2) Revealing experiences of death and dehumanization (3) Describing the internal death of self experience, and (4) Beginning the grief response.  相似文献

Previous research has evaluated the effects of prompt rates on the rate of communicative behavior. More recent research has suggested that dense prompting can result in communicative behavior that is more resistant to change. However, existing research has not considered the impact that higher response rates had on reinforcement rate, a variable known to impact response persistence. The current study systematically replicated previous research by evaluating communicative responding in contexts associated with dense- and lean-prompt schedules and extended existing research by (a) holding reinforcement rates similar across the two prompting schedules (lean and dense), and (b) evaluating the persistence of communicative responding in the contexts associated with each prompting schedule. The results for Experiment 1 clearly replicated and extended previous research. The results for Experiment 2 were equivocal and suggested that previous reinforcement history and response class size impacted outcomes.  相似文献

Pressurized air was repeatedly associated with one of two frequencies of flashing light during performance of a VI 30-sec positive reinforcement schedule by stump-tailed monkeys. As revealed by the relative suppression of bar presses to each of the two visual stimuli, the Ss learned to discriminate between the different flicker frequencies. However, they also showed signs of adapting to the airblast during the course of training, and its location had to be changed in order to maintain discriminative suppression.  相似文献

Two studies examined the consequences of turnover, by investigating factors affecting the job satisfaction of people who remain (i. e., stayers) in response to a coworker (i. e., leaver) who departed for a better job. Consistent with Tesser and Campbell's (1983) self-esteem maintenance model, three factors were found to influence the job satisfaction level of stayers: (a) the extent to which they compared their job situation to the leaver's new one, which was negatively related to stayers’ level of satisfaction, (b) the relevance of the leaver to the stayer for social comparison purposes, which was negatively related to the stayers’ level of satisfaction, and (c) the stayers’ trait self-esteem, which was positively related to the stayers’ level of job satisfaction. Theoretical implications, limitations, and future research directions are discussed.  相似文献
