The Effect of Contextual Interference in implicit and explicit Conditions on motor learning in Slow- Learning Children

The aim of this study was to investigate the effect of contextual interference in implicit and explicit condition on the coordination and motor function in slow- learning children.For this purpose,60 slow- learning children with a mean age of12.28±0.80years where selected in available.After obtaining the terms of entry and consent, based on the pretest scores were divided into four groups(explicit practice without interference, explicit practice with interference,implicit practice without interference,implicit practice with interference).IQ was measured using Wechsler's Intelligence Test, fourth edition, bimanual coordination by the Vienna test and performance with a rotatory follow-up device. Then, the Four-session training (four blocks - nine attempts per session) was performed with a Pursuit rotatory in their special training sessions. After four sessions of training, the participants of the group were again measured in the above variables and the results were recorded as a post-test. For analysis of data, outcomes of the groups were analyzed by mixed analysis of variance 2(learning type)× 2(practice conditions) at post-test and retention stages at a significant level (p≤0.05).The results show that there is no difference between implicit and explicit learning in the acquisition and retention test (p<0.05).There is no difference between implicit and explicit learning in acquiring motor function (p<0.05).But in retention of motor performance, the difference between implicit and explicit learning was significant (p<0.05) and implicit learning showed better performance. In general, it can be said that in slow- learning children, the situation with the interaction of the implicit learning background leads to better memorization.
