The delayed matching-to-sample task was extended to a multiple-unit memory procedure for nonhuman primates by increasing the number of samples shown in succession prior to the matching test. Rhesus monkeys were capable of reconstructing the order of presentation of three successively presented samples. The task is seen as an animal analogue of human memory tasks. 相似文献

Six surfaces from natural environments with different visual textures were photographed at angles of 60, 65, and 70 deg from perpendicular. Measurements were taken of 24 Ss’ judgments of the inferred angles of slant and inferred midpoints of the six textured surfaces represented in the photographs which were viewed in the frontoparallel plane. Judgments of both slant and relative distance within the photographs were influenced by represented angle of slant and by variations in surface texture. 相似文献

A tendency for judgments of stimulus magnitude to be biased in the direction of the value of the immediately preceding stimulus is found in magnitude estimations of loudness. This produces a bias in the empirical psychophysical function that results in underestimation of the exponent of the unbiased function presumed to relate number and stimulus intensity, N = aSn. The biased judgment can be represented as a power product of focal and preceding stimulus intensity, Nij= aS m Sj b. A bias-free estimate of the correct exponent, n, can be obtained from the relation n = m + b. 相似文献

Adult subjects made monocular size judgements in two experiments in which the independent variables of surface texture and restrictions on viewing conditions were manipulated. Texture density gradients of stimulation had a significant influence of size judgements only under the less reduced conditions of observation when subjects could see other textured surfaces beyond the surfaces over which judgements were made. Identical manipulations of surface texture had earlier been found to have a highly significant influence on relative distance judgements (Newman, 1971). The principally negative results were thus taken to imply that subjects extract different information from the texture density gradient when judging size from that extracted when judging relative distance. 相似文献

SCV is a FORTRAN IV subroutine for sequencing combinations of variables. Selection of the combinations can be random with or without replacement and with equal or unequal frequencies of occurrence. Application is illustrated in terms of an interactive process-control experiment, but the subroutine is applicable to any problem requiring the generation of multidimensional sequences or the permutation of a set of numbers. 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
