The organization imposed by children on lists presented in a multitrial free recall task was investigated in two experiments. In the first, 6 and 9 year olds were tested for multitrial free recall of an unstructured noun or mixed list, followed by two sorting trials. Organization was quantified using two structurally comparable indices. One was an index of subjective clustering, based on individual word groupings determined in the sorting trials, and the other was an index of the sequential consistency of recall order over successive trials. The older children had significantly higher scores on recall and subjective clustering but there was no age effect on sequential consistency. In the second experiment 6, 8 and 10 year olds were tested for multitrial free recall of line drawings of common objects. Two sorting trials followed and organization was quantified using the subjective clustering and sequential consistency indices. Recall and subjective clustering scores again showed significant increases with age. As before, no age effect on sequential consistency was found. The results were interpreted in terms of a differential sensitivity of the two indices to an age-related qualitative change in the basis of organization. 相似文献

Two colours were either simultaneously or successively presented. In both cases the time taken to determine whether the colours differed increased as the visual similarity of the colours increased. In another experiment, colours or names of colours were presented successively in different blocks of trials. Here colour similarity affected the discrimination reaction times whenever the second stimulus was a colour. This was taken to suggest that visual mnemonic representations can be generated from the first stimulus. 相似文献

Pigeons were trained in discriminations where S+ and S? shared common visual elements but were distinguished by the presence or absence of a visual feature. When S+ contained the distinctive feature (the feature-positive condition), the pigeons rapidly learned to withold responses to S?: The learning rate was not markedly affected by changes in the relative size of the feature and the common element. When S? contained the distinctive feature (the feature-negative condition), the pigeons learned to withhold responses to S? more rapidly when the feature was large relative to the common element than when the feature was small relative to the common element. This effect was observed when the stimuli were present at the locus of response and when the stimuli were remote from the locus of response. To explain these results, and the results of generalization tests, it was proposed that the effectiveness of the feature in suppressing responding to the common element during feature-negative training depended on the relative size of the feature and the common element. 相似文献
