The research in the effects of violent motion-sensing video game on aggression is scarce, particularly on Asian children. The first object of this research is to examine whether violent motion-sensing video games is positively correlated with children's aggression in Taiwan, where its cultural values discourage aggressive behaviors. Additionally, this research examines whether the GAM illustrate how violent motion-sensing video game influences aggression among Taiwanese children. A survey study was conducted in 2008. More than nine hundred Taiwanese children were surveyed. Analyses of the data revealed that playing violent motion-sensing video game was not significantly associated with high levels of aggression in Taiwanese children, while controlling the influences of other explanatory variables. It seems that GAM was not effective in illustrating the process of violent motion-sensing video game influencing aggression. Although the result failed to demonstrate the influencing pathway of violent motion-sensing video games, the GAM illustrates the process of biological and social environmental modifiers affecting aggression in Taiwanese children. Some implications and limitations of this research were also discussed.
