Although motor learning is generally assumed to be an orderly process, the observed performance curves of individuals and groups of individuals are usually rather irregular with observed points falling both above and below the general trend of the curve. This conflict between theory and observation has typically been resolved by attributing such variations to the chance operation of uncontrolled variables. However, a recent theory describes a mechanism by which such variations might occur. The present paper extends this theory to the problem of performance variability, and presents an analysis of performance curves obtained under two conditions of work-surface height to test this extension.
