Abstract : The purpose of the present study was to explore the effects of practice in a task in which fixed movement patterns are produced. Earlier studies indicated that an encapsulated representation, a motor chunk, develops when a certain movement pattern is repeatedly executed. The motor chunk would be used to control the production of the movement sequence at a processing stage called sequence construction. This would free processing capacity at earlier processing stages and allow for concurrent processing. The present study sought evidence for the sequence construction stage and the notion that the effect of practice at this stage (i.e. motor chunks development) is independent from that at the response selection stage. The reported experiment included a 2500 trial practice phase and four transfer phases including serial response production, stimulus/response reversal, and production of familiar sequences in rapid succession. In the practice phase, independence of response selection and sequence construction was indicated by effects of mapping consistency, foreperiod duration, and sequence length. The transfer phases showed further evidence for independent effects of practice at response selection and sequence construction as well as for concurrent processing.
