Sequential skill learning is central to much of human behaviour. It is known that sequences are hierarchically organized into several chunks of information that enables efficient performance of the acquired skill. We present clustering analysis on response times as subjects learn finger movement sequences of length 24 arranged in two ways – 12 sets of two movements each and 6 sets of four movements each. The experimental results and the analysis point out that greater amount of reorganization of sequences into chunks is more likely when the set-size is kept lower and discuss the cognitive implications of these findings.
