Abstract:Motor skill learning research often investigates the effect of contextual interference (CI) on learning outcomes. In this field, traditionally differences between random practice (RP) and blocked practice (BP) learning outcomes are examined. RP training schedules have been associated with a high CI environment and as a result usually show less improvement over time but better retention than BP training schedules. Motor sequences are chunked such that several smaller pieces of information are integrated into a single larger one. This way a motor sequence can be executed faster. Theoretical interpretation suggests that switching between motor chunks creates a high CI environment. This would occur in sequences where more than one chunk exists. The present paper aimed to examine whether sequences long enough for chunk switching to occur would create high CI such that differences between BP and RP training schedules can be neglected. The findings suggest that by using appropriately long sequences, differences between RP and BP training schedule learning effects do not significantly differ. This would indicate that RP and BP training schedules produce similar learning effects with sequences long enough. Further, this provides a possible way to control improvement and retention effects by changing the length of sequences.
