Objective: this survey aims to exam the limitations in feedback request in the form of self-control in complicated and simple tasks. Methods: Statistic population of the research contained sample of 60 subjects (whose age mean was10/6 ± 1/07). They were placed in four experimental groups of 15 people based on pre-test results. Simple tasks consisted of producing 1-kilogram power with hands. In difficult assignment, however, Volleyball Hammer Service Test was applied. Acquisition stage also contained a session in which each group carried out 6 blocks of 10 attempts (10*6). Results: in the acquisition stage Complementary Factor Variance Analysis Test with repetitive measures, and in the Remembrance Test two-side variance analysis in the significant level of p
Conclusions: The pattern of this findings suggest that in the simple task, the effect of feedback type is more important than its frequencybecause learners can recognize successful trials from unsuccessful trials, but regarding difficult tasks frequency of the feedback is more important than its type.
