  6. Evolution of motor learning theory • Schema theory was Schmidt’s (1975) response to Adams’ (1971) model of motor learning. • Adams proposed a closed loop model, with specific traces for movement and feedback. • Schmidt criticized Adam’s model based on two notions: storage and novelty. • Adams’ model was restricted to linear positioning tasks, limited generalizability.

  7. Schema Theory • In schema theory two memory states are hypothesized. They are: recall and recognition. The terms recall and recognition are taken from the verbal learning literature.

  8. Initial Conditions Desired Outcome Past Actual Outcomes Past Response Specifications Past Sensory Consequences Recognition Schema Recall Schema Expected Sensory Consequences Response Specifications Schmidt (1975). A schema theory of discrete motor learning. Psychological Review, 82,225-260.

  9. Four things are stored to satisfy the goal of the movement: • Initial Conditions • Response Specifications • Sensory Consequences • Response Outcome

  10. The major hypothesis generated in schema theory is the variability of practice hypothesis, one of the most tested hypotheses in motor learning literature.

  11. Acquisition phase of the paradigm used to test the variability of practice hypothesis Constant Practice AAA..., AAA..., AAA… Variable Practice Blocked AAA…, BBB…, CCC… Random BAC…, CBA…, ACB… Serial ABC…, ABC…, ABC…

  12. Retention and transfer phases of the paradigm • Transfer has been tested with tasks both within and outside the range of the already practiced tasks. • Both retention and transfer have been tested. • Several studies have examined the effect of variability of practice on performance of children.

  13. Schmidt’s predictions • Transfer is better to tasks within the range of the originally practiced tasks. • Variable practice produces better transfer than constant practice.

  14. Schema theory still provides impetus for research on the concept of a generalized motor program.

  15. Gentile (1972, 1987, 2000) also supported a variable practice structure for latter stages of learning and for skills that have changing features, such as: open skills and closed skills with intertrial variability.
