This study clarifies the role of two critical semantic operations demanding extra-semantic processing at the sentential level: Aspectual coercion. It complements to provide some evidence on the localist view of the brain. Our rationale for selecting these operations was their pure semantic nature, not relying on morphosyntactic properties. Materials and Methods: Having recruited two age- and education-matched Broca, two Wernicke, and four healthy controls, we conducted a semantic judgment task in which the participants were asked to express their correct semantic judgment in the two coercion and two normal conditions. Results: Our results showed an approximately above-chance performance of the Broca group for all conditions; however, in the Wernicke group, the same result was not observed due to their poor performance in coercion conditions, though in ordinary sentences, they performed much better. Conclusion: Our findings, along with similar off-line and imaging studies, corroborate the view of localism, based on which Wernicke’s area is mainly responsible for the primary semantic operations while Broca’s area predominantly takes over syntactic parsing.
