The present experiment was to test if high-arousing Chinese words can lead to increase repetition priming for emotional semantics. Participants were randomly assigned into two groups: one group was presented with positive words and another group with negative words. In Phase 1 of the experiment, participants rated high-arousing words and neutral words for concreteness. In Phase 2, they made decision to determine if it was novel word (half high-arousing, half neutral). In Phase 3, they were told to value the features of Chinese words which were not presented previously in a 5-point Likert scale and finished some parts of the Basic Personality Inventory (BPI) for assessing and controlling possible cognitive processing bias. The results showed a significant priming effect in two groups and the words presented in Phase 1 had shorter reaction times than the novel words. These findings revealed selective enhancement of Chinese word repetition priming by emotional arousal.
