The purpose was to investigate effects of fatigue on intelligence test performance in the elderly. Fatigue effects were investigated by varying number of previous tests, by introducing breaks, and by using a pre-test fatigue-producing condition. The elderly are not as susceptible to test fatigue as previous results suggested. (Author)

This research uses a complex task (handwheel assembly) to enable comparison between the performance of mentally handicapped adults and adults from a "normal" population, in the acquisition of new work skills. Results add further support for the notion that the potential of mentally handicapped individuals is commonly underestimated. (Editor/RK)

The isolation of the components of intelligent performance and applicability of the componential analysis method to tasks other than analogies are discussed. The article also examines the structure of a componential analysis, the precuing method of task decomposition, and new methods for isolating components in a variety of reasoning tasks.…

The performance of hospitalized paranoid schizophrenics, nonparanoids, and hospitalized controls was compared on motor, perceptual, and cognitive tasks of increasing complexity. The data were examined within the context of comparing differential predictions made by input and central processing theories of information-processing deficit. (Editor)

Purpose of the present experiment was to compare performance of four- and six-year-olds on a conjunctive concept task in which the two relevant values were either within a single dimension (unidimensional) or from two different dimensions (bidimensional). (Authors)

Reflective subjects generated characteristically different and more efficient hypothesis-testing strategies than impulsive subjects. (Author)

The study investigated the effects of expectations upon task performance in a simulated work environment. In a 2 x 2 factorial design, individuals of high and low self-esteem responded to either a favorable or unfavorable expectation. The results were discussed relative to self-consistency formulations and implications for organizational behavior…

These results stand in sharp contrast to those previously reported which concluded that most college students will abandon conservation; the present finding is of strong (though less than perfect) resistance. (Authors/CB)

Study considered whether distinctive orthography would lead to differential recognition performance when high- and low-distinctiveness words served as both study and distracter items. (Author)

This experiment was an attempt to extend recent findings by examining how contextual changes might produce variations in the correct recognition of verbal units' previously presented in a compound display. (Authors/CB)

Biased and unbiased ambiguous sentences, paired with either an expected'' or unexpected'' second sentence, were presented to 80 Ss for judgments of compatibility. The results supported the conclusion that only one meaning was derived for both types of ambiguities during initial comprehension processing. (Author)

The age effect in this study was such that younger children required proportionately more experience with reward than nonreward before they were able to improve their performance on reward problems over six sessions. (Author)

Given a chance to eat the candy or drink the juice in this study, the 5-year-olds, 7-year-olds and young adults failed to conserve and made choices based on what they said was appearance of greater quantity rather than upon the already established equivalencies. (Authors/CB)
