内容简介：

The study of homophones words with different meanings that sound the same--has great potential to inform models of language production. Of particular relevance is a phenomenon termed frequency inheritance, where a low frequency word (e.g., deer) is produced more fluently than would be expected based on its frequency characteristics, presumably because of shared phonology with a high-frequency homophone counterpart (e.g., dear). However, prior studies have been inconsistent in showing frequency inheritance. To explain this inconsistency, we propose a dual nature account of homophony: a high-frequency counterpart exerts two counterposing effects on a low frequency homophone target during the two main stages of naming: (1) a detrimental impact during semantically-driven lexical retrieval; (2) a beneficial impact during phonological retrieval. In a study of naming in participants with chronic aphasia followed by computational investigations, we find strong evidence for the dual nature account of homophony.
