Semantic Typicality Effects in Primary Progressive Aphasia

Riley EA, Barbieri E, Weintraub S, Mesulam MM, Thompson CK

Prototypical items within a semantic category are processed faster than atypical items within the same category. This typicality effect reflects normal representation and processing of semantic categories and when absent may be reflective of lexical-semantic deficits. We examined typicality effects in individuals with semantic and nonsemantic variants of primary progressive aphasia (PPA; semantic-PPA-S, agrammatic-PPA-G), a neurodegenerative disorder characterized by specific decline in language function, and age-matched controls.
