Abstract

An experiment is reported that was set-up to examine the informational role of knowledge of results (KR) in the learning of a single-limb movement timing task. A group with KR practiced 200 trials a day for 5 days prior to receiving a sixth day of practice without KR. The performance of this group was contrasted to another group that practiced 200trials without KR for one day. Traditional movement error and time series analyses revealed that KR serves to calibrate the movement outcome to the task demands and modulate the performance outcome relation between trials. The degree of systematic trial-to-trial modulation was strongly dependent upon the degree of error exhibited on any given trial, and was enhanced under no-KR conditions. Information in KR has bothimmediate and persistent influences on learning and performance that are dependent upon the task constraints and the skill level of the performer.
