摘要：Naming deficits are pervasive in all types of aphasia. For example, agrammatic speakers show greater difficulty with verbs than nouns, while anomic speakers show greater impairment with nouns than verbs (Zingeser & Bemdt, 1990). However, the nature of the processes underlying naming deficits in aphasia is unclear. We examined phonological encoding processes in agrammatic and anomic speakers during noun and verb naming, using a phonological priming paradigm. Previous studies with healthy young speakers have shown that a phonologically related prime (belt) facilitates retrieval of the phonological representation of the target noun (bed), resulting in faster naming latencies compared to unrelated primes. This phonological facilitation (PF) also affects speakers, viewing times to the picture, with reduced fixation times under related prime conditions prior to naming onset, suggesting that the fixation times reflect phonological encoding process (Meyer & van der Meulen, 2000). We hypothesized that if phonological encoding in individuals with aphasia is intact, they will evince normal PF effects, reflected by shorter naming latencies and fixation times in the phonologically related, compared to the unrelated，condition.
