Virtually all motor learning studies have shown spaced practice to be superior to massed practice. Most of the apparent exceptions, such as the work of Cook, involve tasks in which symbolic responses play a dominant role - such tasks as spider mazes, punch board mazes, mechanical puzzles, etc. (1, 2). The few remaining exceptions are studies in which the term "spaced practice" is a misnomer. That is, the performance of the so-called "spaced" groups was affected as much by the inhibitory effects of work decrement as was the performance of the massed practice groups (3).
