The purpose of this study was to investigate the effect of combining random or block schedules with a errorless learning model (errorless or errorfull practice) on learning and automaticity of dart throwing skill in both high and low working memory conditions. One hundred participants with no experience in dart throwing were selected and divided into two classes of high and low working memory using the N back working memory test. Subjects of each class were randomly divided into five groups: block-errorless, block-errorfull, random-errorless, random-errorfull and random. After the pre-test and the acquisition phase (three sessions of 70 trials), experimental groups participated in the retention test (with and without cognitive secondary task). The results showed that in both high and low working memory conditions, the random-errorless group performed the best performance and the random-errorfull group performed the worst, although the performance of the block groups were better in the low working memory condition. This result indicates that in high working memory conditions, cognitive processing in block-errorless in not sufficient to generate cognitive effort and therefore is not sufficient to make appropriate challenge to practice. The results also showed that the three groups including random-errorless, random-errorfull and random, performed better in high working memory condition than low working memory condition at the same time with secondary cognitive task. The results of this study show that working memory will play a very important role in learning motor skills and especially in achieving high levels of task automation.
