The effects of using picture prompts on the acquisition, generalization, and maintenance of complex vocational tasks were evaluated within a multiple baseline design across subjects and tasks. Five moderately and severely mentally retarded adolescents were first trained to use picture prompts to guide their performance on one or more complex tasks. Following training, posttesting with and without the picture prompts was conducted to evaluate the effects of training and to determine maintenance effects over a 2- to 4-week interval. Generalization of performance across tasks was assessed with three of the students who were provided novel tasks (with and without picture prompts) without training. Results indicated that picture prompts can be successfully used to promote both acquisition and generalization of performance, and that subsequent training time on a novel task was reduced when the use of picture prompts had been previously trained. 相似文献

Asymmetry of perception in free viewing of chimeric faces 总被引:3,自引:0,他引:3
We have devised a new free-vision task to index functional cerebral asymmetry for processing facial characteristics. Confirming its sensitivity to properties of lateralized hemispheric functions, left- and right-handers were clearly differentiated on this task with respect to several aspects of performance that conform with known differences between handedness groups in hemispheric asymmetry. Additionally, there were highly reliable and stable individual differences in perceptual asymmetries within handedness. Analyses of items in the task revealed that most of the differences between items in the asymmetries they elicited were random. 相似文献

The reward value of peers 总被引:1,自引:0,他引:1
Sixteen socially isolate preschoolers were classified as peer- or non-peer-oriented on the basis of their responses to a test devised to measure the reward value of peers. Half of the subjects in each classification were assigned to a modeling treatment and viewed a film depicting appropriate social behavior in the nursery school; half served as controls and saw an animal film. Peer-oriented modeling film subjects increased significantly more in their peer social interactions at posttest and follow-up assessments than did the non-peer-oriented modeling group. In addition, both peer-oriented and non-peer-oriented modeling groups were significantly higher on peer interaction than the control groups. Alternative and supplemental procedures for increasing isolate preschoolers' social interaction are discussed. 相似文献

Four experiments examined the hypothesis that the Valins (1966) false physiological feedback effect with attractiveness ratings of slides is due to experimenter demand. Experiments 1 and 2 showed significant feedback effects with 5-sec feedback periods, previously reported by Barefoot and Straub (1971) to be too brief a time to search the slides for a cause of the apparent physiological arousal. Experiments 3 and 4 had 17 variations of instructions (emotional, nonemotional), stimuli (slides of people, scenic tourist slides), and type of feedback information (heart rate, eyeblink, or none). The typical false feedback effect was found under many conditions that did not seem to meet the presumptive attributional requirements for the effect. In Experiment 4, only subjects who said they were supposed to rate feedback slides higher showed the effect, regardless of instructions, stimuli, or type of feedback. The overall results are interpreted in terms of experimenter demand and stimulus salience effects. 相似文献

Comparisons are made between BILOG version 2.2 and LOGIST 5.0 Version 2.5 in estimating the item parameters, traits, item characteristic functions (ICFs), and test characteristic functions (TCFs) for the three-parameter logistic model. Data analyzed are simulated item responses for 1000 simulees and one 10-item test, four 20-item tests, and four 40-item tests. LOGIST usually was faster than BILOG in producing maximum likelihood estimates. BILOG almost always produced more accurate estimates of individual item parameters. In estimating ICFs and TCFs BILOG was more accurate for the 10-item test, and the two programs were about equally accurate for the 20- and 40-item tests.I am grateful to Robert J. Mislevy, Martha L. Stocking, and Marilyn S. Wingersky for many helpful comments on an earlier version of this paper. I would also like to thank Hamid Kamrani and Bongmyoung Park for getting LOGIST and BILOG running and keeping them running under changing computer systems at CTB/McGraw-Hill. 相似文献

In this two-experiment investigation, the long-term (at least 6 months) employment of 51 moderately mentally retarded clients who were placed into 64 supported employment positions was first evaluated relative to 10 training and posttraining components that comprised a supported employment training package. In Experiment 1, chi-square analyses were used to identify three components that differentiated successful (employed for at least 6 months) from unsuccessful clients. In Experiment 2, 4 successful clients were further evaluated in a nonconcurrent multiple baseline design to determine whether the three variables identified during the group analysis (client advocate, collateral behavior, and follow-up plan) were included in the training packages. These results are discussed in terms of the need to establish better the functional variables of supported employment training programs. 相似文献

BENEFITS AND COSTS OF SUPPORTED EMPLOYMENT: AN ANALYSIS OF THE ILLINOIS SUPPORTED EMPLOYMENT PROJECT
Ronald W. Conley Frank R. Rusch Wendy B. McCaughrin Jeffrey Tines 《Journal of applied behavior analysis》1989,22(4):441-447
This investigation presents a cost-benefit analysis completed for one of 27 states implementing supported employment as a result of federal funding. Based upon the benefits and costs detailed, society realized a $0.75 return for every $1.00 invested in supported employment in Illinois. Supported employees realized a 37% increase in their earnings over a comparable period. The results of this study are discussed and recommendations are made for similar analyses across states. 相似文献

Similar structured diagnostic interviews about the child were given by different interviewers to a cohort of 307 mother-child pairs. A diagnosis was made by computer on each interview, using specified criteria. Diagnoses on mother-child interviews were compared using the kappa statistic. Kappas of .30 or higher were found for the diagnosis of antisocial personality, conduct disorder, enuresis, mixed behavior-neurotic disorder, and possible depression. Comparisons were made for sex and age. Possible depression and enuresis were diagnosed reliably at all age levels and for both sexes. The limitations of the interview and diagnostic system used are discussed. The findings support the need for further efforts to develop diagnostic research interviews for use with children and adolescents. 相似文献
