Specific and varied practice of motor skill.
To assess the potential effect of specific and varied practice on the development of motor schema, 64 children in two age groups (8 yr. and 12 yr.) were tested on a simple throwing task at the beginning and end of a 12-wk. physical education program. For the throwing test the children were assigned to either a specificity or a schema group (varied practice). The task was performed without visual feedback, but knowledge of results was given after each trial. Prior to both tests at the criterion target, the specific group was given practice throws using the criterion target distance, whereas the schema group practiced on two other targets. No differences were found between the two groups at the beginning of the program but on the posttest those children receiving a variety of practice on the throwing task performed significantly better than the specific-practice group. Thus it was suggested that a varied practice schedule may facilitate the initial formation of motor schema, and this process may be enhanced by participation in a physical education program.
