Recognition and recall in slow movements: separate memory states?
If slow positioning movements are governed only by a recognition process (e.g., Schmidt, 1975) then subject's performance should be independent of the mode or response (active versus passive). Two groups learned a criterion movement under either active or passive conditions following which KR was withdrawn. Although no differences were apparent on acquisition trials, active-group performance deteriorated dramatically during KR withdrawal while passive-group performance remained stable. These results suggest that recall and recognition are potentially separable in slow movements on the basis of the information available to the performer.
