The effect of self-controlled and instructor- controlled feedback after good and poor trials on learning of force-production task in old subjects

Navid Hadadi and Esmail Kheirjoo

This study aimed to compare feedback after good and poor trials in self–control and instructor-control condition on acquisition and learning of force production task in old subjects. Subjects were randomly divided into three groups: instructor-control feedback after good and poor trials and self–control feedback groups. All participants produced 10 kg force in acquisition phase. They couldn't see the produced force and received KR on two trials in each 6-trial block. At the end of acquisition phase, subjects of self–control feedback group were divided into 2 groups of self– control feedback after good and poor trail. After 48 hour, they performed a retention and transfer tests without KR. To analyze data, one – way ANOVA and post Hoc test were used (P≤5%). Results showed there was significant difference between self–control and instructor-control groups, significant different between feedback after good and poor trials in the instructor-controlled group also, but no significant different in self-controlled group.
