Sentence Production in Semantic Dementia
What is it about?
This paper investigates the effect of verb complexity and inflection on sentence production in semantic dementia, a form of primary progressive aphasia. The semantics of the verbs as well as the kind of arguments they take affect sentence production. Inflection is not impaired per se but it takes place at cost of verb retrieval in complex verbs. We found large individual variability and correlations with the cognitive and language screening tests.
