Evidence for recognition and recall schemata.
Two experiments manipulated elements postulated to be crucial for the formation of recognition and recall schemata for discrete motor skills. Experiment 1 tested predictions for the formation of a schema to recognize novel and practiced positioning movements. Sensations of practiced locations, followed by knowledge of results, enabled accurate judgment of movement extent. The specification of distances before active practice movements did not help recognition performance. To test recall schema, Experiment 2 allowed practice with active movements over specified distances, or unspecified passive movements. The allowance of response specifications during practice provided clear superiority of recall-dependent performance. This aspect of recall memory should enable the construction of movements with extents and velocities different from those practiced.
