The authors report 5 experiments that explored the role of error in motor learning. Participants practiced 4 distinct keypress sequences that varied in the amounts of advance information (i.e., choice) about which key to press next in the sequence. The amount of advance information resulted in differing levels of error during practice, which in general, was inversely related to retention performance. Although these findings support a beneficial role of error in motor learning, they also suggest that not all errors are equal in the learning process. Rather, we make a distinction between factors that induce errors that have desirable influences on learning compared to those that have undesirable effects.
