Studies of Normal and Disordered Sentence Processing

Studies of Normal and Disordered Sentence Processing

Studies of sentence processing examine normal and disordered real-time computation of various sentence types, including those with long-distance dependencies.

Automatic processing of wh- and NP-movement in agrammatic aphasiOn-line processing: Tracking Eye Movements. This work uses eyetracking while listening and speaking to investigate how sentences are processed in real time in both cognitively healthy and brain-damaged individuals. We also use eyetracking to examine changes in sentence processing associated with recovery of language in stroke-induced aphasia and decline of language in primary progressive aphasia (PPA).

  • Electrophysiological Studies. This work examines the electrical activity of the brain, using Event Related Potentials (ERPs), associated with language processing in healthy and aphasic individuals. Brain waves are recorded as participants listen to sentences. We study aspects of semantic and syntactic processing in both healthy adults and those with stroke-induced and primary progressive aphasia (PPA) and examine changes over time (recovery or decline) in these patient populations.

Verb Processing Studies

Because verbs are central to sentence processing and selective deficits in verb production is common in aphasia, we seek to understand how verbs are normally computed and the factors that affect this, including argument structure complexity, derivational status, and other properties, and what factors affect verb production in aphasia. Supported by the NIH 4 R01 DC001948.
