Some questionnaires were employed to study the characteristics of elaborative coding for a serial motor task in basketball. 64 male experts on basketball (18-22 yrs.) and 56 male novices (18-20 yrs.) were divided into following four different rehearsal conditions, i. e. a) pictorial presentation of movement patterns without physical rehearsal, b) modeled and verbal explanation without physical rehearsal, c) pictorial presentation with fine motor rehearsal, and d) pictorial presentation with gross motor rehearsal. After the reproduction of the serial motor task, subjects were required to reply how they had encoded it. The speed and accuracy in performing the task were measured for each rehearsal condition, too. The results were as follows.
1) The experts organized the to-be-remembered items of movement based on the procedural knowledges of "out-side screen play" and "2men break".Then they encoded the serial motor patterns by using the visual image of moving picture. On the other hand, the novices did not organize the items, since they have little knowledge of those plays. And they encoded by using the visual image of pictorial pattern.
2) The experts performed the serial motor task much faster and much more accurately than the novices. Then the roles of organization in the elaborative coding processes were discussed in relation to recall performance.
