Abstract:Motor learning is an essential skill needed in everyday life. However, it seems that it is still up for debate what the best strategy entails when learning a motor task. There is consensus that learning tasks that are complex and serial in nature may benefit from progressive learning, which is also supported by the Cognitive Framework for Sequential Motor Behaviour (C-SMB). The framework details that singular movements are chunked together to ensure faster and more efficient performance. In order to examine whether this is indeed the case, participants (N = 24) performed a Dance-Step Discrete Sequence Production (DS-DSP) Task, either learning the sequences as a whole (N = 12) or progressively (N = 12). There seemed to be no actual difference between the two groups once learning was completed. However, significant impact on the process of learning was found, both in terms of accuracy and response time, pointing towards differences in cognitive processing between the groups. This was further confirmed when looking at the response time pattern of the single steps taken. The progressive learners showed significantly faster processing in the first few steps of the sequence, while their later steps followed a similar pattern to the whole learners. It is possible that whole learners used an associative mode throughout the full sequence in order to execute the steps. The results allude that progressive learners used two different strategies across different parts of the sequence, namely processing its first part in chunking mode, and the latter steps in association mode. This points to chunking only being activated under specific circumstances when performing a DS-DSP task.
