摘要

The hypothesized role of Broca鈥檚 area in sentence processing ranges from domain-general executive function to domain-specific computation that is specific to certain syntactic structures. We examined this issue by manipulating syntactic structure and conflict between syntactic and semantic cues in a sentence processing task. Functional neuroimaging revealed that activation within several Broca鈥檚 area regions of interest reflected the parametric variation in syntactic-semantic conflict. These results suggest that Broca鈥檚 area supports sentence processing by mediating between multiple incompatible constraints on sentence interpretation, consistent with this area鈥檚 well-known role in conflict resolution in other linguistic and non-linguistic tasks.
