Abstract: One explicit self report scale and four implicit tests which were based on the Implicit Association Test were used to measure the gender self concept in the study. The result showed: (1) Implicit Association Test is valid, sensitive to the implicit gender self concept. (2) gender self concept shows significant gender difference on implicit measures, but on most explicit measures it does not show significant gender difference except explicit femininity measure. (3) gender self concept is a model of dual components which involves an implicit gender self concept and an explicit gender self concept. The former is an integrated structure, while the latter consists of two dimensions: one is positive male trait vs. negative female trait, the other is positive female trait vs. negative male trait, and the two are uncorrelated.

Key words: gender self concept, implicit association test, implicit gender self concept
