The effect of methylphenidate on information-processing efficiency was studied in 12 hyperactive, nonretarded children. Performance on six efficiency tasks (Posner Letter Matching, Reaction Time, Memory Search, Category Verification, Item Identification, and Word-Span) and a general measure of on-task behavior were compared for children receiving methylphenidate or a placebo. The median drug dosage was .38 mg/kg, and it was ingested 1 1/2 hours prior to testing. Children blind to the drug-placebo condition were tested on 4 days. In general, methylphenidate-related improvements in attention to on-task behaviors were found. An overall analysis of processing speed suggested that methylphenidate improved efficiency. Methylphenidate significantly decreased reaction times to simple and complex stimulus arrays; differences due to the drug remained even when on-task attentive behaviors were statistically removed. Significantly fewer identification errors occurred on the Posner task in the methylphenidate condition. Results indicated that methylphenidate improved general attentional behaviors and positively influenced processes that define perceptual efficiency.The first author was supported by NIH Training Grant No. HD 07184.

We evaluated an approach for teaching an intermediate community living skill via a leisure-dance activity to institutionalized severely and profoundly retarded persons. The targeted skill was considered as intermediate in contrast to a community living skill per se because it was based on successful performances of higher functioning, noninstitutionalized retarded persons as opposed to nonhandicapped individuals. Definitions for appropriate dancing were established and then validated through observations of the performance of retarded persons living in the local community. The dance skills were then taught to four participants through serial training in leg movements, arm movements, and coordinated leg and arm movements, plus follow-up trainer supervision. Generalization was also programmed by way of multiple trainers and training settings. Results during structured assessments showed that all four residents acquired the dance skills and that both serial training and follow-up supervision were necessary for skill acquisition. Generalized increases in appropriate dancing at dances attended by the participants and retarded persons from the community were also demonstrated. However, in most cases some active supervision by caregivers was needed to enhance the generalized improvements. Results are discussed in terms of the applicability of this approach for validating goals when training other community-related skills to low-functioning populations. 相似文献

A strategy for the study of social interaction in the family is reviewed that places particular emphasis on those variables that have proven useful or hold promise for the identification and understanding of factors that affect human social development. First, the heavy reliance on observational data and other main features of the approach are described. Second, an attempt is made to summarize some of the more significant findings from this type of research that have added significantly to our understanding of social development within the family. Third, the major research methods used in this approach are described, as well as the research that needs to be done in order to improve the methodology. Finally, a number of major gaps in our substantive knowledge about social interaction within the family are indicated. 相似文献

This study evaluated the use of protective equipment in treating self-injurious behavior (SIB) exhibited by three retarded persons. In Experiment 1, the equipment was first applied continuously during 20-min sessions in individual multiple baseline designs across settings. Results showed substantial reductions in head hitting, eye gouging, and hand biting. Brief periods of time-out with the protective equipment were later made contingent on SIB and combined with a differential reinforcement procedure. Reduced levels of SIB was maintained with all subjects. Additionally, the amount of time during which the equipment was applied decreased as the SIB diminished. Experiment 2 evaluated the use of contingent protective equipment (the final condition in Experiment 1) when applied directly in the subjects' living uints during the day. During Experiment 2, SIB remained at or below the levels found at the termination of Experiment 1. Finally, in an effort to assess the long-term effectiveness of the procedure, responsibility for implementation was given to the staff who were typically assigned to provide therapy to the subjects. Follow-up probe observations conducted up to 104 days after termination of the final experimental condition showed continued low levels of both SIB and equipment usage. Results of these experiments suggest that contingent protective equipment and differential reinforcement may be effective in reducing chronic self-injury. 相似文献

Young children with sleep problems received either standard or graduated ignoring treatment. Both brief treatments were superior to a wait-list control condition and resulted in comparable improvements in bedtime and nighttime sleep problems. At bedtime, the treatments did not differ with respect to maternal compliance and stress. For nighttime wakings, mothers in the graduated ignoring group reported higher rates of compliance and less treatment-related stress. Maternal characteristics predicted treatment outcome in the standard ignoring condition. Following treatment, only positive side effects were observed. When compared to the wait-list group, mothers in the standard ignoring group reported less verbose discipline and decreased stress in parenting, while mothers in the graduated ignoring group reported improved parent–child relationships. Treatment gains were maintained over a 2-month follow-up period. 相似文献

We evaluated public verbal feedback as a potentially effective and efficient means of improving institutional staff performance. Following baseline observations of the self-help training conducted by three groups of direct care staff with clients who had profound mental retardation, verbal feedback was presented publicly to individual staff during routine staff meetings. The feedback addressed the (in)frequency of the staffs training endeavors and required only a few minutes to present. Results indicated that each group of staff increased their client training when the public verbal feedback was provided. Probes of client self-help skills indicated that as the frequency of staff-conducted training increased, client skill acquisition improved. Generalization measures indicated that staff increased only those work behaviors for which they received feedback. Results are discussed regarding the efficiency of public verbal feedback as a means of improving staff performance, as well as the need for research to continue expanding and refining a technology of staff management. 相似文献

We evaluated the proficiency of the federal Medicaid program's survey process for evaluating intermediate care facilities for the mentally retarded. In Study 1, an observational analysis of active treatment during leisure times in living units suggested that these surveys did not discriminate between certified and noncertified units. In Study 2, a reactivity analysis of a survey indicated that direct-care staff performed differently during the survey by increasing interactions with clients and decreasing nonwork behavior. Similarly, results of Study 3 showed increases in client access to leisure materials during a survey. In Study 4, questionnaire results indicated considerable variability among service providers' opinions on the consistency, accuracy, and objectivity with which survey teams determine agency standard compliance. Results are discussed regarding effects of the questionable proficiency of survey processes and the potential utility of behavioral assessment methodologies to improve such processes. 相似文献

We evaluated a structural analysis methodology for enhancing the utility of a staff management program. In Experiment 1, a structural analysis of direct-care staff behavior in a mental retardation facility revealed differences in work patterns over time. Specific times were identified when few basic care duties were necessary and staff engaged in nonwork activity. In Experiment 2, a management program was implemented to increase staff members' training activities during periods identified through the structural analysis. The program was accompanied by increases in training activities and decreases in nonwork behavior. The improvements were maintained during a 43-week period while the most labor-intensive component of the program was withdrawn. Staff acceptability measures indicated a positive response to the management intervention, although responses varied across components within the multifaceted program. The increased training was accompanied by beneficial changes among clients with profound handicaps. Results are discussed regarding practical considerations for improving staff performance and for adopting innovations resulting from applied research. 相似文献
