Three experiments tested the hypothesis that pictorial memory is much less dependent on rehearsal than is verbal memory. Experiment I examined incidental learning since this is assumed to reflect learning with little or no rehearsal. Following a classification task, intentional and incidental learning for pictures and for words was compared. The superiority of pictorial memory was especially marked in incidental learning. Experiment II showed that this result was not due to differences in the amount of processing required to classify pictures and words. RTs to classify words and pictures did not differ, and incidental learning was again superior for pictures. In Experiment III rehearsal opportunity was restricted by a concurrent task during presentation of word and picture lists, and the decrement was very much greater for word learning than for picture learning. It was concluded that manipulation of rehearsal opportunity has relatively little effect on pictorial memory. 相似文献

Research in dream recall frequency has failed to isolate psychological variables which clearly and reliably differentiate frequent dream recallers from infrequent recallers. The present study tested the hypothesis that frequent recallers have a greater capacity for visual imagery than infrequent recallers. Subjects selected on the basis of reported dream recall frequency were administered a Paired-Associate Learning task designed to measure visual imagery, a rating scale of imagery clarity and vividness, and a subjective measure of imagery controllability. The results provide support for the hypothesis and, together with other evidence, suggest that a generalized capacity for visualization may contribute to the quality of the dreaming experience and, consequently, to its recallability. 相似文献

In two experiments induced movement of an object was produced to demonstrate that movement of the background influences the perceived localization of the object in space. The Roelofs (asymmetry) effect could be used to explain only part of the shift in localization in Experiment1. The asymmetry effect was excluded from Experiment2 by the procedure employed. It was concluded that the Roelofs effect is a sufficient, but not necessary, condition for the effects of induced movement to occur, and that relative displacement of the target and background plays an important part in the illusion. Furthermore, it was shown that the effects of induced movement can occur even when the border of the background remains stationary. 相似文献

This study presents data on the luminance difference at which a hue difference is first perceived between two identical spectral lights. Thresholds were obtained for both luminance increments and decrements from a 2.00 log troland standard for wavelengths between 470 nm and 690 nm. A predicted luminance threshold for each wavelength was calculated based on wavelength discrimination data and the Purdy constant hue contours; i.e. that luminance at which the constant hue contour intersects the wavelength discrimination bound for a given wavelength. A generally good agreement was obtained between observed and predicted values. 相似文献

The use of binomial coefficients in place of factorials to shorten the calculation of exact probabilities for 2 × 2 and 2 ×r contingency tables is discussed. A useful set of inequalities for estimating the cumulative probabilities in the tail of the distribution from the probability of a single table is given. A table of binomial coefficients with four significant places andn through 60 is provided. 相似文献
