Processing, Knowledge of Results, and a Multi-Dimensional Task

Abstract

Individuals learned a motor skill having temporal and spatial dimensions. Two groups, determined by amount of allotted processing time (3 or 6 sec.), were tested. Analyzed data were specific to absolute and variable errors associated with movement. A series of 2 (post-knowledge delay) × 3 (trial blocks) repeated-measures multivariate analysis indicated reduction of errors (both temporal and spatial) by groups. Follow-up analysis favored the 6-sec. group while the 3-sec. group learned only the accuracy portion of the task.
