Abstract: The present research explored the interrelation of implicit learning and explicit learning. It used converging operation of two kinds of learning materials in order to compare five experimental conditions with each other. The subjects consisted of 100 high school students from Shanghai. The results are as follows. 1.Through implicit learning, the students could acquired abstract knowledge, on which the present study emphasized. 2.There was the interrelation between implicit learning and explicit learning, sometimes facilitating each other, sometimes conflicting with each other, sometimes more contributions of implicit learning and sometimes contrarily, which depended on the difficulty of the learning materials.

Key words: implicit learning, explicit learning, artificial grammar, converging operation
