Abstract:The acquisition of new motor skills is important for every individual and has a great impact on daily life. This study focused on the contextual interference (CI) effect with seven-key sequences in an extended practice environment. This effect was tested with the use of the Discrete Sequence Production Task. The CI-effect was expected to be present in the blocked (BP) and random practice (RP) condition. Participants in BP condition practised the three sequences separately, while participants in RP condition practised the sequences in random order. The hypothesis was partly accepted, because the expected appearance of the CI-effect was only present during the practice phase, while it was not in the retention phase. Two possible factors can explain this. First, the extended practice influences the CI-effect in some cases. Second, the development of motor chunks could have influenced the practice of a sequence in a way that one sequence is represented as a few shorter sequences in a row. In this way, the BP condition has more similarities with the RP condition, which weakens the CI-effect. Future research should focus on the complexity of a motor sequence and the possible non-existence of the CI-effect in both laboratory and applied settings.
