Chronic tic disorders are characterized by involuntary motor and vocal tics, which are influenced by contextual factors. Recent research has shown that (a) children can suppress tics for brief periods of time, (b) suppression is enhanced when programmed reinforcement is provided for tic-free intervals, and (c) short periods of suppression do not result in a paradoxical "rebound" in tic frequency when active suppression has ceased. The current study extended existing research in three important ways. First, we examined whether tic suppression ability decreased as suppression duration increased from 5 to 25 to 40 min. Second, we examined post-suppression tic frequency to test whether longer periods of suppression were more likely to be associated with a rebound effect. Finally, we explored neuropsychological predictors of tic suppression. Thirteen children with Tourette syndrome or a chronic tic disorder completed the study. Results showed that (a) tic suppression was sustained for all of the suppression durations, (b) rebound effects were not observed following any of the suppression durations, and (c) ability to suppress was correlated with omission, but not commission errors on a continuous performance task. Implications of these findings are discussed. 相似文献

We conducted a two-study examination of relationships between abusive supervision and subordinates’ workplace deviance. Consistent with predictions derived from power/dependence theory, the results of a cross-sectional study with employees from three organizations suggest that abusive supervision is more strongly associated with subordinates’ organization deviance and supervisor-directed deviance when subordinates’ intention to quit is higher. The results also support the prediction that when intention to quit is higher, abusive supervision is more strongly associated with supervisor-directed deviance than with organization-directed deviance. These results were replicated in a second study, a two-wave investigation of people employed in a variety of industries and occupations. 相似文献

The present study investigated the effects of contingency‐specifying rules and a token economy to decrease the latency to comply with academic instructions by a 16‐year‐old girl with acquired brain injury. Results showed that treatment was successful in reducing academic response latencies. These results replicate previous research in which differential reinforcement was used to decrease slow responding to academic tasks. 相似文献

The recommendation to reserve the most potent reinforcers for unprompted responses during acquisition programming has little published empirical support for its purported benefits (e.g., rapid acquisition, decreased errors, and decreased prompt dependence). The purpose of the current investigation was to compare the delivery of high‐quality reinforcers exclusively following unprompted responses (differential reinforcement) with the delivery of high‐quality reinforcers following both prompted and unprompted responses (nondifferential reinforcement) on the skill acquisition of 2 children with autism. Results indicated that both were effective teaching procedures, although the differential reinforcement procedure was more reliable in producing skill acquisition. These preliminary findings suggest that the differential reinforcement of unprompted responses may be the most appropriate default approach to teaching children with autism. 相似文献

To determine if choroidal melanoma patients want cytogenetic prognostic information. Ninety-nine choroidal melanoma patients
completed a questionnaire regarding their opinions about receiving prognostic information. The perceived usefulness of prognostic
information was evaluated in patients who had undergone cytogenetic testing. Depressive symptoms, quality of life, and interest
in supportive counseling during test receipt were assessed. Ninety-seven percent of respondents reported that they would have
wanted prognostic information at the time of their treatment and 98% of respondents reported that supportive counseling should
be offered when prognostic information is given. Patients who had received a more favorable prognostic result were more likely
to endorse the usefulness of cytogenetic testing than were patients who had received a less favorable prognostic result. Psychological
status did not vary significantly as a function of cytogenetic test result. Prognostic information was important to patients
with choroidal melanoma, even in the absence of prophylactic measures which might improve prognosis. 相似文献

The Internet offers possibilities for sexuality research that could not have been imagined even a decade ago. Although Internet
users are not representative of the general population, they are easily accessible, and the openness with which they discuss
sensitive topics has created a tremendous and largely untapped pool of respondents for sex research. Moreover, the web provides
access to populations that are largely hidden and difficult to reach using traditional methods. In this article, we explore
such issues as sampling, research design, data collection and management, and the ethics of web-based research. In doing so,
we review past research, investigate the advantages and disadvantages of using the Internet in sexuality studies, draw examples
from our web-based study of involuntary celibacy, and recommend guidelines for future web based inquiries. 相似文献
