Prediction models employing multiple linear regression of raw scores, multiple linear regression of factor scores, the single best predictor, and a nine-point decision rule index were compared. The subjects were 296 clients undergoing vocational counseling and evaluation. Predictor variables included performance ratings, demographic variables, and WAIS subtest scores; the criterion was employment status upon program completion. The least statistically sophisticated model, employing the single best predictor, was the most successful approach. Considerable shrinkage in power of prediction was demonstrated upon cross-validation particularly for multiple linear regression of raw scores model, indicating the necessity of cross-validating prediction schemes. Additional suggestions are made to those designing prediction studies. 相似文献

Rats bar pressing on a 1-min fixed-interval schedule for 45-mg food pellets became polydipsic when water was concurrently available. They were then exposed to conditions in which each lick on the drinking tube produced a timeout period during which the food-schedule lever was retracted and the fixed-interval timer either did or did not continue to operate. Licks occurring within a timeout period extended its duration. As the duration of the lick-initiated timeout period was increased logarithmically through four values from 10 sec to 80 sec, lick rates as well as water intake rates generally decreased for all three subjects. As timeout duration was progressively increased, the rate of licks occurring in the absense of, but producing, timeouts decreased for all three rats, whereas the rate of licks occurring in the presence of timeout periods remained essentially constant. Water-intake rates and, with one exception, lick rates were suppressed more by timeout periods during which the fixed-interval timer did not continue to operate. These results indicate that lick-contingent timeout from positive reinforcement reduces schedule-induced drinking, and this suppressive effect is greater when the timeout period necessarily increases the interreinforcement interval beyond its minimum duration than when it does not. 相似文献

Improvements on a technique for the study of consummatory behavior and appetitive conditioning in fishes are described: a target-strike detector module easily incorporated into conventional relay programming equipment, a liquid-food formula highly attractive to goldfish and carp, a reliable Teflon-headed syringe plunger capable of handling gritty foods, and a silent food-pumping system. 相似文献

For each response to a nipple from which they were trained to take liquid food, goldfish were punished with a brief ac shock administered through a pair of stainless steel electrodes placed either to the right and left of the animal, over and under it, or in front and back of it. As anticipated, on the assumption that the aversiveness of shock is a function of the potential difference across the animal's body, the right-left orientation of the electrodes was found to produce the least suppression of feeding and the front-back orientation the most. 相似文献

Although we live in an age dominated by science and technology, there exists an increasingly popular anti-science sentiment. This study describes the development of a scale to assess the degree of personal acceptance of supernatural causality versus acceptance of scientific explanation. In addition to the psychometric data concerning validity and reliability of the scale, data are presented which showed the personality factor of supernaturalism to be independent of orthodox religious attitudes. Results indicated a significantly greater supernatural acceptance for women, and a positive relation of supernaturalism with external locus of control. 相似文献

This paper clears up some misunderstandings of Woodard's Phenomenological and Perceptual Research Methodology presented by Beshai in a recent critique. Beshai's critique helps demonstrate and validate a number of themes in Woodard's Perceptually Oriented Hypnosis. First, for each of us, our historical learnings provide the basis for scientific progress but at the same time may impede new views and even a more comprehensive understanding of hypnosis. Second, hypnosis is fundamentally a process of differentiating personal meanings that can be vastly different for various individuals. Third, Beshai uses a quantitatively based approach to understanding phenomenon different from Woodard's qualitative research process. Last, holistic understanding of hypnosis is impeded when aspects of the phenomenal field are taken quantitatively out of context. 相似文献

Transitive inference (TI) in animals (e.g., choosing A over C on the basis of knowing that A is better than B and B is better than C) has been interpreted by some as reflecting a declarative logical inference process. We invert this anthropomorphic interpretation by providing evidence that humans can exhibit TI-like behavior on the basis of simpler associative mechanisms that underlie many theories of animal learning. In this study, human participants were trained on a five-pair TI problem (A+B-, B+C-, C+D-, D+E-, E+F-) and, unlike in previous human TI studies, were prevented from becoming explicitly aware of the logical hierarchy, so they could not employ logical reasoning. They were then tested with three problems: B versus D, B versus E, and C versus E. Participants only reliably chose B over E, whereas the other test conditions yielded chance performance. This result is inconsistent with the use of logical reasoning and is instead consistent with an account developed to explain earlier TI studies with rats that found the same pattern of results. In this account, choice performance is based on differential associative strengths across the stimulus items that develop over training, despite equal overt reinforcement. 相似文献
