Biographical Profile

Michael Walsh Dickey's research centers on sentence comprehension and production in adults, the neural bases of these abilities, and their impairments in aphasia. His research also extends to measurement and prediction of treatment response in aphasia, focusing on psycholinguistically-motivated impairment-level behavioral treatment. In carrying out this work, he has examined complex sentence comprehension (ellipsis, wh-movement and garden-path sentences); verb-argument processing; tense and temporal interpretation; and both lexical-level and sentence-level aphasia treatment. His work uses behavioral methods (reading measures, reaction-time tasks, the visual-world paradigm), meta-analytic modelling (hierarchical linear modelling, logistic regression), and neuroimaging methods (structural neuroimaging; voxel-based lesion-symptom mapping) to explore these questions.
