The purpose of this study was to determine the effect of the distinctiveness of stimulus cues on the relevant and irrelevant dimensions - both in original learning and in transfer - on the learning of intradimensional shifts by retarded subjects. (Author)

The isolation effect was studied in an experiment which measured, in different groups, either free recall or recognition of a series of words, each series containing one isolated item. (Editor)

The present experiments were an attempt to clarify the mixed results on the interitem manipulation of implicit associative responses in verbal discrimination. (Author)

Two experiments contrasted the effects of high and low ego strength (as measured by Cattell's Sixteen Personality Factor Questionnaire) on confidence thresholds (FG scores) under the anticipation and recall methods. (Editor)

A rule for selecting components from the stimulus compounds was established during first-list learning. (Editor)

To test the prediction from generalization theory that the ease of learning an item will be inversely related to the size of the set of which it is a member, 80 subjects were exposed to a serially presented list of pairs for 15 trials. (Editor)

The results of these experiments supported the contention that the use of different organizational strategies on two word lists reduced the amount of retroactive inhibition in free recall. (Author/RK)

The purpose of this study was to determine if stimuli of high potential imagery (pictures) would be less subject to negative transfer than stimuli of lower potential imagery (concrete words). (Editor)

The differential effects of delayed auditory feedback (DAF) upon four tasks varying in cognitive complexity were examined with undergraduates as subjects. The tasks were the construction or reading of a prose passage, and reading or naming, in a specified sequential order, word labels or pictorial representations of objects attached to a display…

Spanish-English bilinguals were tested for the speed with which they could recognize a word in one language as a member of a previously presented set of words in either language. Reaction time increased with the size of the presented set of words. Investigates the "translation effect" and its influence on information processing. (Editor/RK)

Older people seem to have difficulty learning new materials, perhaps because it takes them longer to retrieve relevant encoding information from memory. To assess the effects of age on speed of retrieval, 60 health males from 25 to 74 were shown pictures of common objects they were name aloud as quickly as possible. (Editor)

Hypothesis refining is the combining of two separate rules (conjunctive concept), the combination of which is more accurate than either rule alone. Each of 70 subjects was reinforced independently for either rule alone or their combination under one and only one of seven reinforcement conditions. Tests Verplanck's paradigm, a model for studying…

The influence of stimulus number and familiarity on judged duration were investigated. Results showed that the number of stimulus elements presented within a given interval affected its perceived duration, although the familiarity of those elements (as defined herein) did not. (Editor/RK)

The possibility that subjective contours are an artifact of brightness contrast was explored. Concludes that subjective contour and brightness contrast are distinct perceptual phenomena but share a dependency on the processing of edge information transmitted through the achromatic channels of the visual system. (Editor/RK)

In a series of three experiments on the role of memory in solving attribute-identification problems, the subjects did or did not have to remember their response and/or the stimulus for processing during any given intertrial interval. (Editor)
