| Abstract: |
Many complex behaviors consist of sequentially ordered actions. When acquiring a novel sequential skill, the transition between actions can be performed with increasing speed. This observation has led to the idea that the elementary actions are bound together during the learning process. Two ideas for this process have been proposed: First, statistical probabilities between different elementary actions could be acquired. Secondly, discrete groupings of elementary actions – so-called chunks - could emerge with learning. We discuss the differences between these two ideas and compare the ability of the two models to predict inter-press time intervals (IPIs) measured by a discrete sequence production task. We find a greater ability of the chunk model to predict participants’ IPIs throughout learning. |
