Objective: To develop the native Chinese Affective Picture System (CAPS) for future research on emotion.!Methods: 852 pictures were screened out to make up of CAPS. 46 Chinese university students were collected to rate the valence, arousal and dominance by self-report in a 9-point rating scale for CAPS.!Results: The standard deviations of scores on valence and dominance were greater than that on arousal. Scatter plot showed that the score distribution on the dimension of valence and arousal was wide in CAPS.! Conclusion: Though IAPS (International Affective Picture System) is highly internationally-accessible, there are still significant differences between the two sources. The native Chinese Affective Picture System is necessary.
