CO-WORKER IMPLEMENTED JOB TRAINING: THE USE OF COINCIDENTAL TRAINING AND QUALITY-CONTROL CHECKING ON THE FOOD PREPARATION SKILLS OF TRAINEES WITH MENTAL RETARDATION

In two studies, co-workers of persons with disabilities were taught to use coincidental training procedures while completing their own jobs. In Study 1, the effects of coincidental training on the salad-making skills of 3 trainees with mild and moderate mental retardation were evaluated. Coincidental training by co-workers resulted in improved accuracy of the salad-making skills of the trainees. In Study 2, trainees were also coincidentally taught to make quality-control checks of their salads. An alternating treatments and multiple baseline design indicated that the trainees more readily acquired the skills when taught to check the correctness of their work.     

Eyewitness accuracy and confidence: within- versus between-subjects correlations

Previous researchers using between-subjects comparisons have found eyewitness confidence and accuracy to be only negligibly correlated. In this study, we examined the predictive power of confidence in within-subject terms. Ninety-six subjects answered, and made confidence ratings for, a series of questions about a crime they witnessed. The average between-subjects and within-subject accuracy-confidence correlations were comparably low: r = .14 (p less than .001) and r = .17 (p less than .001), respectively. Confidence is neither a useful predictor of the accuracy of a particular witness nor of the accuracy of particular statements made by the same witness. Another possible predictor of accuracy, response latency, correlated only negligibly with accuracy (r = -.09 within subjects), but more strongly with confidence (r = -.27 within subjects). This pattern was obtained for both between-subjects and within-subject comparisons. The theoretical and practical implications of these results are discussed.     

Fundamentalist religion and its effect on mental health

The national self-help group, Fundamentalists Anonymous (F.A.), has focused attention upon mental problems that may be caused or exacerbated by authoritarian religion. In this article we outline assertions about the mental problems caused by membership in fundamentalist religion, illustrate these with two case histories, briefly discuss intervention strategies, and describe conceptual and empirical issues. While former members have presented problems severe enough to warrant professional treatment, a causal link between their symptoms and their religious membership has not yet been established, because there is little empirical work on the subject.An earlier version of this paper was presented at the annual meeting of the American Psychological Association in New York in August 1987.The authors express gratitude to Stephen Strack, Ph.D.; Robert Meagher, Ph.D.; Herman Feifel, Ph.D.; and Ted Schoenberger, M.D., for their helpful comments on previous drafts of this paper.     

Effects of test anxiety, tests, and sleep on children''s performance

This study examined the interrelationship between children's test anxiety, sleep, and performance. The subjects, 239 sixth and seventh graders, responded to questionnaires examining sleep behavior and test anxiety on a day when they had a major exam in school, and on a day when they did not. They also completed a vigilance task on both days. The results showed that partial sleep loss (i.e., under 3 hr) did not adversely influence subjects' performance on the vigilance task or on the actual class exam. However, the results did reveal that test anxiety was negatively related to performance on the class exam.     

Instructional programs for psychology: A review and analysis

This paper presents 10 general observations about current software for instruction in psychology and examines selected examples employing four instructional techniques for computer-assisted instruction. We find that although the number of programs employing experimental or data-oriented approaches to psychology as a primary vehicle of instruction is increasing, tutorial drill and practice programs and gaming are not well represented.     

FORTRAN subroutine for an EEG feedback digital filter

A method of constructing digital filters is outlined and illustrated in an application for research uses of EEG feedback. The method is based on least squares estimation with geometric weighting. Old data in the time series are discounted according to age, as new data arrive. Recurrence relations are used, allowing the computations to be performed in real time. A FORTRAN digital filter is formulated that simultaneously estimates (1) the spectral power in a band centered at a target frequency, (2) the total spectral power, and (3) the dominant frequency.
