Stereotype refers to people's fixed, generalized and general views on a certain kind of people or things. It has a great influence on our social information processing. It has both positive and negative aspects. Greenwald and Banaji (1995) pointed out that we often have implicit stereotypes, which are not easy to recognize, but it still affects our views on the characteristics of a special social group. At this time, we can use the method of measuring implicit attitude and stereotype proposed by Towers-Schwen (2001+0)-sincere channel.

Designed by Barnaji and Harding (1996), using the principle of priming effect. This method is to present a subdomain-level priming stimulus to the subjects-these stimuli are only presented for a short time, which makes the subjects unable to identify or identify them. Kawakami did an experiment at (200 1). In the experiment, the priming word is black or white photos, and the presentation time is 15 to 30 milliseconds. Then present letters or symbols as clues to a group of words, and finally present some words related to black and white stereotypes or neutral words related to letters. Let the subjects judge whether these words can be used to describe a specific part of speech. The results show that after the black picture begins, the subjects respond faster to the words related to the black stereotype, while after the white picture begins, they respond faster to the words related to the white stereotype.
