Abstract:Some researches of social facilitation have been gradually formed since 1898 and developed some theories,such as dominant response theory,evaluation theory,distractionconflict theory,and so on. However,there exist some contradictions about these experimental studies,for understanding the effect of social facilitation on sport performance. By utilizing the metaanalysis,this article analyzes the issue. The results show that(1)the relation appeared a moderate effect(r=0.32)between social facilitation and skilled movements; (2) the relation is negative correlation between social facilitation and nonskilled action(r=-0.11). Meanwhile,the author analyzes the effect of personality on social facilitation and further explained the limitations.
