Abstract
The purpose of the present study was to investigate the effects of contextual interference on the immediate transfer performance of coincidence-anticipation timing task by individuals with mild mental retardation (MR). A total of 20 individuals with mental retardation with a mean chronological age of 17.3 years were randomly assigned to either a blocked or random practice condition. Following 128 practice trials with coincidence-anticipation timing task of various visual stimuli, subjects were transferred to two novel visual stimuli. Transfer analysis showed that subjects in the random practice condition exhibited less error than subjects in the blocked practice conditions. However, these differences were not statistically significant. Results provide marginal support for the contention that greater contextual interference (random practice) leads to better transfer performance than other types of practice conditions.
