英文摘要The brain activity associated with automatic semantic priming has been extensively studied. Thus far there has been no prior study that directly contrasts the neural mechanisms of semantic and affective priming. The present study employed event-related fMRI to examine the common and distinct neural bases underlying conceptual and affective priming with a lexical decision task. A special type of emotional word. a dual-meaning word containing both conceptual meaning and affective meaning, was adopted as target. Short stimulus onset asynchrony (SOA) (50 ms) was used to emphasize automatic processing. Fifteen participants were scanned in the present study. We found that the left middle/superior temporal gyrus was the brain region involved in both automatic conceptual and affective priming effects, suggesting general lexical-semantic processing that share in the two types of priming. The left inferior frontal gyrus and right superior temporal gyrus were found to be the conceptual-specific areas in automatic priming effect, consistent with the role of these areas in more extensive within-category semantic processes. The results also revealed that the left fusiform gyrus and left insula were the affective-specific regions in automatic priming effect, demonstrating the involvement of the left fusiform gyrus in automatic affective priming effect, and clarifying the role of the insula in emotional processing rather than conceptual processing. Despite comparable behavioral effects of automatic conceptual priming and affective priming, the present study revealed a neural dissociation of the two types of priming, as well as the shared neural bases.
