In this study, we used a four-step social validation process to identify and validate critical skill components that constitute high school students' conversational behavior. The four steps were nominating target behaviors, establishing a normative range of performance, manipulating simulations of behavioral dimensions, and comparing ratings of judges to levels of performance on those behavioral dimensions. Multiple measures, both quantitative and qualitative, suggested that the rate and percentage of time initiating and responding verbally, the percentage of time attending, and the percentage of time not engaging in distracting motor behavior related to favorable ratings by a wide variety of 60 judges. Findings are discussed in relation to the utility of the multistep social validation process and the identification of critical social skill components as targets of interventions. 相似文献

研究了41名弱智儿童。采用时间样本的方法收集材料,以期从动态角度了解弱智儿童在上课时和自由活动时的行为表现。按园别和智力落后程度两个方面对被试在上课时的8大类行为和自由活动时的7大类行为进行了分析。结果发现:班级人数、不同教学方法和智力落后程度与弱智儿童的行为表现有关。还对收集材料的方法、园别和智力落后程度与弱智儿童的行为表现的关系、高频率的自娱活动等,进行了讨论。最后,根据研究结果对教师提出了教学建议。 相似文献

This study investigated the effectiveness of self-monitoring on the on-task behavior and vocational production rates of 5 elementary students with moderate mental retardation during biweekly pre-vocational workshop sessions. They were taught to use a recording form to monitor their behavior and were cued to monitor by audiotaped tones. A multiple-baseline design across tasks was used to demonstrate a functional relationship between self-monitoring and both on-task behavior and task productivity. Once this relationship was demonstrated, the monitoring form and audiotape were withdrawn through fading procedures. Results indicated that (a) self-monitoring increased both on-task behavior and vocational task production rates, (b) performance gains maintained while cues and monitoring forms were withdrawn, and (c) gains maintained over several weeks in the absence of prompts (i.e., forms and tones). 相似文献

Preliminary work suggested that the quantity of food ingested by retarded individuals who usually ruminated following meals was related to the frequency and duration of ruminating responses. This possible relation was experimentally examined by systematically varying food quantity from regular portions to satiation levels for three retarded individuals who exhibited high levels of ruminating. A clear functional relation of food quantity to ruminating emerged, with satiation procedures producing rapid and large decreases in the relatively high frequencies and durations of ruminating characteristic of baseline food quantity conditions. 相似文献

Simultaneous prompting, a type of antecedent prompt and test procedure, was used to teach the chained task of making juice from a frozen concentrate using a pictorial recipe to four elementary-aged students with moderate intellectual disabilities. Using a multiple probe design, all students acquired the task and maintained the behavior with at least 85% accuracy up to 60 days after training was terminated. In addition, students generalized the skill across settings and materials. The students' ability to expressively identify the words shown on the recipe cards was tested prior to and after training. Although not directly trained, three of the four students increased their ability to read the words. 相似文献

Contingent physical guidance was used to treat chronic aerophagia. This consisted of guiding the participant's hand over her mouth following each attempt to engage in aerophagia. A wristwatch was then correlated with the contingent physical guidance procedure. Responding remained low in the presence of the wristwatch, even after contingent physical guidance was withdrawn. 相似文献

A number of hypotheses have emerged regarding the etiology of physical aggression in persons with mental retardation. Although a multicomponent model is appropriate, results of functional analysis-based studies have yielded promising results in identifying instigating and maintaining factors of aggression. However, the relationship between functional variables and conditions such as psychiatric diagnosis to aggressive behavior has yet to be investigated in persons with mental retardation. We conducted a study examining the prevalence of environmental or physical factors in aggressive behavior in mentally retarded persons with and without psychiatric disturbance. One hundred and thirty-five individuals with mental retardation who exhibited physical aggression were assessed with the Questions About Behavior Function Scale (QABF) to identify environmental or physical contribution to aggressive behavior. One or more behavioral functions were identified for 75% of the participants. Additionally, of 66 of the participants scoring above the clinical cutoff on an assessment for dual diagnosis, 75% met criteria for an environmental or physical function for aggression. No significant differences in number of participants with an identifiable function of aggression were found between the no dual diagnosis and dual diagnosis groups. Our findings underscore the importance of identifying functions underlying aggressive behavior in persons with mental retardation, and the need to consider functional variables regardless of psychiatric condition in treatment planning efforts for such individuals. 相似文献

Pre-Therapy is a theory conceptualizing about psychological contact practiced with low-functioning persons. This category includes schizophrenic people, retarded people, and geriatric clients who are too isolated and withdrawn for regular psychotherapy. The techniques, known as Contact Reflections, are Situational, Facial, Word-for-Word, Bodily, and Reiterative Reflections. The therapist expresses a foundational belief in implicit selfhood as presented in episodes of lucidity. There is compassion for the effort at self-expression even at regressed levels. The therapist's reception of symptomatic expression conveys empathy. The case history illustrates the application of Contact Reflections with a catatonic client without the use of neuroleptics. This gives a clearer example of the psychological effects of Pre-Therapy. 相似文献

Behavioral momentum in computer-presented discriminations in individuals with severe mental retardation 下载免费PDF全文
Behavioral momentum was examined in 2 individuals with severe mental retardation via within-subject manipulations of obtained reinforcer rates. Subjects performed self-paced discrimination problems presented on a touch screen computer monitor. Two different problems, Tasks A and B, alternated in blocks of 15 trials on a multiple schedule. Reinforcers were snack foods. The reinforcement schedule for Task A was continuous (fixed-ratio 1) and the schedule for Task B was continuous in some conditions and variable ratio in other conditions. Behavioral momentum was assessed in test sessions by prefeeding, presenting response-independent food, and making available alternatives to the tasks. When the obtained reinforcer rate for Task A was at least twice that for Task B, resistance to change was greater for Task A. When both reinforcer rates and response rates were a pproximately equal for the two tasks, resistance to change was approximately equal. These results are consistent with behavioral momentum effects. They extend previous findings with humans by examining momentum in self-initiated discrete-trial discrimination tasks with ratio schedules, and by isolating relative reinforcer rates as a controlling variable via within-subject manipulations. 相似文献

Typically developing children have been shown to imitate the specific means used by an adult to achieve an object‐directed outcome, even if a more efficient method is available. It has been argued that this behaviour can be attributed to social and communicative motivations. The purpose of this study was to investigate whether children with autism spectrum disorders (ASD), relative to children with Down syndrome (DS), show a reduced tendency to copy the exact means used by an adult to produce a novel outcome. To achieve this a sample of 34 children (22 with ASD and 12 with DS) were given a test of object‐directed imitation. Contrary to expectation, children in both groups imitated the specific method of the model to the same high extent. This finding is in line with suggestions that object‐directed imitation is relatively spared in children with autism but is surprising given arguments linking such imitation to socially based motivations. Nevertheless, children's ability to successfully copy the model was associated with their communicative ability, providing some support for the link between imitation and communication. 相似文献
