Abstract: This research explored the feature binding mechanism of the IAD students on attention and working memory levels. In experiment 1, ten undergraduates of both IAD and non-IAD groups were selected to complete the IC paradigm tasks. In experiment 2, fifteen undergraduates for each group participated in recognition tasks. The results showed that the feature binding ability of IAD group was remarkably damaged on attention level and only general working memory mechanism on working memory level. It revealed that the damage of feature binding mechanism was one of the important mechanisms of IAD phenomenon, but its senior psychological research was remained to be carried out.
