Adults with developmental disabilities frequently have both deficits in appropriate social skills and excesses in inappropriate social behavior (Matson, LeBlanc, & Weinheimer, 1999). Typically, published treatment studies have focused on social skills training procedures that teach and promote the use of new social behaviors. However, only a few studies have focused on management of existing social behaviors that are problematic because they occur excessively or in an inappropriate context (Wright, Herzog, & Seymour, 1992). The current study focuses on management of three types of inappropriate social behavior in a 26‐year‐old male with moderate mental retardation: inappropriate social interactions, inappropriate sexual behavior, and verbal aggression. A token economy with response cost procedure was implemented using a DRO interval as the basis for earning tokens. Using a multiple‐baseline design across behaviors, each of the three types of inappropriate social behavior was successfully treated. After demonstrating the success of the procedure, the DRO interval was increased while maintaining the reductions in inappropriate social behaviors. Appropriate behaviors such as initiating conversation, shaking hands, etc maintained throughout the intervention. Copyright © 2000 John Wiley & Sons, Ltd. 相似文献

Recent anatomical and electrophysiological evidence suggests that the anterior cingulate cortex (ACC) is relatively late to mature. This brain region appears to be critical for monitoring, evaluating, and adjusting ongoing behaviors. This monitoring elicits characteristic ERP components including the error-related negativity (ERN), error positivity (Pe) and correct-related negativity (CRN), with the ERN clearly relating to activation of the ACC; however, little attention has been paid to the examination of these ERP components in children. The present study examined developmental differences in the ERN, Pe, and CRN in normal 10-year-old children and young adults in a standard visual flanker task. We found that children had smaller ERNs than adults, with no between-group differences on the Pe, and some ambiguity concerning the CRN. Results provide electrophysiological support either for late maturation of the ACC or late involvement of the ACC in response monitoring. Results also suggest that there is some functional independence of response-monitoring ERP components. Error-related ERPs may be a useful tool in studying the development of this brain region and its role in behavior in normal and atypical development. 相似文献
