Previous investigations of the social behavior of handicapped preschool children (Journal of Applied Behavior Analysis, 1974, 7 , 583–590; Journal of Applied Behavior Analysis, 1976, 9 , 31–40; Journal of Applied Behavior Analysis, 1977, 10 , 289–298) demonstrated that introduction of adult or peer confederate intervention agents produced substantial increases in levels of positive social behavior emitted by the subjects. In addition, it was observed that changes in rates of positive social behavior emitted by recipients of intervention tactics were accompanied by parallel changes in rates of positive social behavior emitted by interacting peers. However, with one limited exception, sudden removals of arranged intervention procedures were followed by immediate reductions in the levels of positive social behavior emitted by subjects and peers in each study. The current investigation was designed to examine the effects of response-dependent removal of intervention procedures on the positive behavior of three socially withdrawn preschool boys. Interactive effects on the social behavior of classroom peers who did not receive adult prompts and contingent attention events were also examined. A combination of withdrawal of treatment and multiple baseline procedures was employed. The three target subjects received fixed numbers of prompts and contingent attention events during Intervention I and Intervention II, Phase 1 conditions. During Intervention II, Phase 2 conditions, prompts and contingent attention events were reduced on a response-dependent basis for two subjects and on a response-independent basis for the third subject. The results suggest that: (a) the intervention procedures produced marked increases in positive social behavior emitted by each subject; (b) response-dependent fading and thinning, contrasted with response-independent tactics, maintained levels of positive social behavior equivalent to those observed during Intervention I and Intervention II, Phase 1 conditions; (c) changes in positive and negative behaviors emitted by peers paralleled changes in positive and negative behaviors emitted by each subject; and (d) no “spillover” of treatment effects was noted for subjects during periods in which they were not direct recipients of intervention procedures. 相似文献

The authors propose that self-of-the-therapist work is most productive when therapists and supervisors approach family of origin issues and historical life events in a balanced way and suggest that they move to an approach that ideally liberates restraints posed by self-of-the-therapist issues, while at the same time accesses resources available to therapists because of the same issues. This is a shift from the primarily restraint focus that has dominated self-of-the-therapist work. This paper also provides personal experiences of the authors, guidelines on how to create safety and balance, as well as practical examples of self-of-the-therapist exercises. 相似文献

In event-related potential (ERP) studies, the left-parietal old/new effect is commonly considered as a neural correlate of recollection. In memory exclusion tasks, the effect is usually observed when the targeted information is identified, but it is not necessarily present when studied items are rejected as nontargets. Interestingly, both the presence and the absence of such old/new effects to nontargets have been regarded as indicator for strategic retrieval. We reviewed previous ERP studies using memory exclusion tasks to analyze the reaction time (RT) pattern in such studies, as well as the influence of task difficulty on the occurrence of nontarget retrieval. We identified 44 test conditions, reported in 24 studies, and subjected the behavioral data to a meta-analysis. The RTs to correctly rejected new items were shorter than the RTs to hits, in particular in studies that required differentiating conceptual or perceptual information at test. When the retrieval of target information was prioritized, RTs to nontargets were delayed relative to targets. Without such prioritization, no such RT differences were observed. For test conditions with nontarget retrieval, the retrieval accuracy was poorer compared with test conditions without such retrieval. The findings support previous studies that claimed that nontarget retrieval becomes more likely when target retrieval is difficult, but the strong overlap in task difficulty between conditions with and without nontarget retrieval indicates that other, partly yet to-be-identified factors contribute to the occurrence of nontarget retrieval as well. 相似文献
