Abstract
This study investigated the effect of audiovisual integration on action-perception transfer.40 subjects were randomly divided four groups: visual, visual-auditory, control visual and control visual-auditory. Visual groups watched pattern skilled basketball player and other groups in addition to watching pattern skilled basketball player, heard Elbow angular velocity as sonification. In first stage, the pattern is presented to subjects for five times and them replying to ten questions about different aspects of pattern. Then they performed parameter recognition and pattern recongnition tests. In second stage, experimental groups watch pattern five times again and perform it after each watch. Control groups watch pattern similar to experimental group but they must not perform it. All groups responded to the questionnaire and participated in a recognition tests again. Results showed that before action, in “percent confidence reply” and no “reply to questions” there is significant different between experimental groups. But after action in both “percent confidence reply” and “reply to questions” there was significant different between experimental groups and control groups (p<0.05). In this study was confirmed effect of visual-auditory integration on action-perception transfer. This results is explainable based of Common Coding Theory, Direct Matching Hypothesis and Predictive Models. The results are consistent with modality appropriateness hypothesis.

Abstract
The purpose of this study was to investigate the role of high and low reinvestment in the acquisition, retention and automaticity of dart throwing skill based on the interference-error model. One hundred participants were selected and divided into two categories of high and low movement reinvestment. Subjects of each category were randomly divided into five groups: block-errorless, block-errorfull, random-errorless, random-errorfull and random. Based on the results, the best and worst performance was observed for the random-errorless and random-errorfull groups respectively. There was a significant difference between categories of high and low reinvestment in retention and automaticity tests in favor of low reinvestment. In both the acquisition and retention test, the block groups performed better in the high reinvestment category and the random groups performed better in the low reinvestment category. At the automaticity phase, all groups executed better in the low reinvestment category. The results show that the level of reinvestment can play an important role in learning and automaticity of motor skills. People with lower level of reinvestment perform better in practice conditions with more cognitive effort (random practice) and people with a higher level of reinvestment perform better in practice conditions with less cognitive effort (block practice).
