Summary This paper develops three theoretical models to predict the numbers generated by Ss in an experiment described by Baird and Noma, 1975, Exp. II. The models (digit, base, and quarter) are each grounded on different assumptions about the process underlying number generation without the constraints of physical stimuli usually present in psychophysical tasks. Each of the models proved applicable to a restricted subrange of the physical continuum from 1–1000. A combination of models seems necessary to adequately predict number generation.This article is the second in a five-part series. Reprint requests should be sent to John C. Baird. 相似文献

An experimental group of lemon sharks received 100 daily presentations of light flash as the conditioned stimulus (CS) and electric shock as the unconditioned stimulus (US) in a classical conditioning situation. The conditioned responses (CRs) and unconditioned responses (URs) under observation consisted of extensions of the nictitating membrane. Separate control groups received either (a) no CS or US, (b) CS-alone, or (c) completely random presentations of CS and US. Few CRs occurred in the experimental group at the outset of conditioning, but the percentage of CRs during the second half of the first acquisition session exceeded 95%. Conditioning stabilized above 95% CRs during Acquisition Sessions 3 through 7. These responses could not be attributed to pseudoconditioning, sensitization, or other nonassociative factors. When the experimental group was subsequently given six CS-alone sessions, the course of extinction was gradual. Most results seemed similar to those previously obtained during classical conditioning of the nictitating membrane in rabbits. 相似文献

An algorithm is described that computes relative frequencies of occurrence of all arbitrarily long substrings of sequential data, such as are obtained from experiments in learning/memory and verbal interaction. The algorithm offers high speed and provides systematization for the computation of empirical conditional probabilities. Use of this algorithm allows application of probabilistic and information theoretic disciplines to reveal dependencies between events separated arbitrarily in time. 相似文献

The hypothesis that success influences task preferences was tested by subjecting 230 Ss to three different success-failure reinforcement schedules and observing subsequent preferences for the tasks concerned. Success ratios of 85-15%, 70-30%, and 50-50% in tasks dealing with unpreferred stimuli were used. Results supported the hypothesis: the probability of change in task preference was greatest under high success reinforcement ratio conditions. 相似文献

The aim of the experiment was to find out whether saccadiceve movements have any effect on perceived visual directions. ihe method was to alter the parameters of the oculomotor system so that the eye movement made in response to a peripheral target was inappropriate to the retinal locus of its image. It was found that this procedure had no effect on the perceived location of the peripheral target; and it was concluded that a specific retinal locus is more or less rigidly associated with a corresponding visual direction, but not with a particular magnitude of ocular rotation. 相似文献

This study reports normative data describing the combinations of various VPI high point codes associated with educational preferences classified into one of six of Holland's occupational environments and an undecided category. Eight hundred thirty-one male and 129 female college freshmen were queried regarding their educational preferences and were administered the VPI directly prior to college enrollment. The comparisons between preferences and VPI combinations revealed that Intellectual and Realistic, Social and Enterprising, Conventional and Enterprising, and Social and Artistic, seem to go together frequently for male students. The female sample revealed that Social and Artistic VPI codes were common. 相似文献

The hardware and software for a computer-controlled training and testing system for primates are described. The computer (DDP-116 in the Computer-Controlled Psychology Laboratory at Carnegie-Mellon University) controls all stimulus presentation, reinforcement, and records data in a form ready for analysis on a larger computer. 相似文献

An experiment was carried out to test the hypothesis that performance on a task which involves a shift of attention between spatially separated sources would be lower under noise conditions than one which involved no such shift. The results indicated that the hypothesis was not proved; rather they showed that the subject's performance on the shift of attention task was better under noise than under quiet. An attempt is made to put forward possible reasons for this occurrence. 相似文献

In a free-responding situation in which reinforcements are scheduled by a variable interval program, the durations of reinforced inter-response times are shown to be a function of the durations of all inter-response times produced by S and of the frequency of reinforcement.Based on a portion of the author's doctoral dissertation, and supported in part by an NIMH predoctoral research fellowship. Suggestions by W. K. Estes increased the intelligibility of this paper. 相似文献

This study investigated the prediction of burnout from job characteristics, emotional intelligence, motivation and pay among bank employees. It also examined the interactions of emotional intelligence, motivation, pay and job characteristics in the prediction of burnout. Data obtained from 230 (Males = 127, Females = 103) bank employees were analysed using Pearson's Product Moment Correlation and multiple regression analysis. Results showed that theses variables jointly and separately negatively predicted burnout components. The results further indicated that emotional intelligence, motivation and pay separately interacted with some job characteristic components to negatively predict some burnout components. The findings imply that emotional intelligence, motivation and pay could be considered by counsellors when designing interventions to reduce burnout among bank employees. 相似文献
