Abstract: This article studied the priming effect of 4 emotion models, We selected 240 undergraduates, and broke them into 4 groups, 3 of them were experimental, and one is control. We brought the photos of pleasure, fear and sadness to the experimental groups, and brought the neutral one to control group. And then inspected the station of 4 groups. Results are obvious, the priming effect by photo is clear, degree of experimental groups exceed control groups, especially pleasure and sadness. The priming effect changed with time, and passive emotion decreased sharply with time, and active emotion increased obviously in a short time（5 minutes）. This might be caused by mental promotion

Key words: emotion priming, time effect, emotion models
