Abstract

Recent reviews about the effects of distribution of practice in motor learning have produced quite divergent conclusions. While there is agreement that massed practice depresses performance, the effect on learning has no firm consensus. One position is that massed practice depresses learning, although there are many that argue for no learning effect. In the present paper we review this literature. When distribution is considered in terms of the length of the inter-trial interval, there is strong evidence that massed practice depresses performance and learning (when learning is assessed by absolute retention measures). This conclusion was confirmed by the results of a meta-analysis. This finding is discussed relative to other literature on distribution of practice as well as some recent issues in motor learning.

Reviewer Notes

This was a fairly influential study about spaced (distributed) practice versus massed practice for motor learning. It’s a meta-analysis of 116 studies (but only 47 were included in the analysis), and was made more valuable given the differentiation between performance and learning effects. However, this study lacks a lot of detail that would have made it much more useful.
