Reduced neural activation have been consistently observed during repeated items processing, a phenomenon termed repetition suppression. The present study used functional magnetic resonance imaging ( fMRI ) to investigate whether and how stimuli of emotional valence affects repetition suppression by adopting Chinese personality‐trait words as materials. Seventeen participants were required to read the negative and neutral Chinese personality‐trait words silently. And then they were presented with repeated and novel items during scanning. Results showed significant repetition suppression in the inferior occipital gyrus only for neutral personality‐trait words, whereas similar repetition suppression in the left inferior temporal gyrus and left middle temporal gyrus was revealed for both the word types. These results indicated common and distinct neural substrates during processing Chinese repeated negative and neutral personality‐trait words.
