Several studies have shown that on a motor task the performance of a group practicing under relatively massed conditions is poorer than the performance of a group practicing under distributed conditions. Subsequent to rest, the performance of the massed-practice group is nearer the level of the distributed-practice group, but a residual difference remains (hereinafter referred to as residual difference) no matter how long the rest period is. However, a study by Bilodeau (3) obtained results which are interpreted as indicating the lack of such residual difference. After overnight rests the initial rate of responding on each of ten days was similar for both massed-and distributed-practice groups. The task used was the manual crank. This task may be classified as a "self-paced" task, that is, the rate of responding is set by the performing subject. It is also pointed out that the task involves a minimum of learning.
