Abstract: Research on Attitudes was an important problem in Social Psychology. People usually paid close attention to an explicit attitude under conscious statute, and were interested in implicit attitude under unconscious statute recently. Wilson and Lindsey suggested that people can have dual attitudes, which are different evaluations of the same attitude object —explicit attitude and implicit attitude. This idea was a strong challenge to traditional concept of attitude and measure approach. In this paper, the origin, contents and types of dual attitudes theory was elaborated, and empirical supports about the dual attitudes model was reviewed. Furthermore, we put forward some implications to the future research about attitude change, attitude-behavior consistency and attitude measurement.

Key words: attitudes, explicit attitude, implicit attitude, dual attitudes
