Random practice has been reported to demand greater time for movement preparation during acquisition than blocked practice. The present study revealed that this could be attributed to a more complete engagement of the motor programming process during random practice. This cost, however, was localized to the motor programming subprocess that S. T. Klapp (1995) associated with organizing the internal structure of a movement chunk rather than an alternative subprocess responsible for organizing movement chunks into the correct serial order. The more thorough employment of motor programming during acquisition by random practice participants resulted in a more efficient use of this planning operation during retention, as well as more accurate movement reproduction. These data support the claim that practice conditions high in contextual interference support improvements in both movement preparation and memory strength.
