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)

This research investigated the extent to which three suggested divided- attention effects--time delay, noise addition, and response bias change, as assessed by three cross-over-model parameters--were manifest when a manual, compensatory tracking task was performed concurrently with two secondary tasks.

This research finds that the experience of time-in-passing is an inverse function of the processing demanded by a concurrent task. An attentional model is suggested and evaluated against the literature. (Editor/RK)

This paper describes a methodological approach to the reading processes, involving the use of measures of speed of response or reaction time (RT) obtained from subjects while performing reading related tasks. Following a review of the literature on measures of RT, two experiments currently being done at the University of Minnesota are described…

Piaget, in describing the sequence of classificatory development, describes class inclusion as composed of two processes; hierarchical classification and post-whole comparisons. In the experiment reported here, elementary school children, trained in the concept of sets in first grade mathematics were given a task where they were required to assess…

This study was designed to measure adult performance as related to age. Using methodology derived from information theory, information processing ability was measured with the individuals performing as a communication system. Fifty-five school teachers, ranging in age from 20 to 66, served as subjects. In four groups, the subjects judged the sizes…
