Perceptual Motor Performance

A laboratory investigation was conducted to determine if synchronization between the work rhythm and the respiratory biorhythm benefits perceptual-motor performance. The effect of work-respiratory (W–R) synchronization on reaction time, error rate, and perceived difficulty was evaluated for a visual choice reaction time task. Interstimulus intervals were chosen to induce a work rhythm. Prior to the experiment, the task was performed in a self-paced mode so that a baseline work rate could be identified for each subject. Each subject (N=22) then performed the task at 3 machine-paced work rhythms; 1) equal to the work rhythm of the baseline work rate, 2) 33% faster than the work rhythm of the baseline work rate, and 3) 33% slower than the work rhythm of the baseline work rate. Each condition consisted of two, 4 min trials separated by a brief rest break. Work rate (in responses per minute) was held constant across conditions through adjustments in task structure. Regression analysis revealed that W–R synchronization was associated with a 1% reduction in error rate and a 15 msec reduction in reaction time. These results suggest that W–R synchronization benefits perceptual–motor performance of repetitive tasks.

The motor performance of 32 college men was measured on the following tests: arm strength, arm reaction and movement times, arm-and-leg serial reaction and movement times. Specificity of variance of individual differences was found for single, simple, and discrete limb movements and for three programmed series of large RT-MT movements which involved 240 responses.

Schizophrenic Patients

It has been clinically observed that psychiatric patients in general (6, 11) and schizophrenic patients in particular (1, 4) show abnormalities of mental speed, being “retarded” or slower than normals on many measures. Confirmatory evidence on this point is to be found but much of the early work on speed of schizophrenic reactivity used measures of speed of motor performance (12, 13) or of reaction time under various conditions (6), ignoring more fundamental slowness of thought processes. The present studies are concentrated on the recent finding that schizophrenics show abnormally slow mental speed measured in a problem-solving situation (4, 18, 19). The aim of the investigation was to discover the exact conditions under which this abnormality appears, and, thence, by manipulating the experimental conditions, to be able to bring speed of mental functioning under experimental control. This paper describes the attempt to bring speed under control by means of drugs. A second paper (2) deals with the effect of practice upon mental speed.
