Face processing and name retrieval in an anomic aphasic: names are stored separately from semantic information about...

Recent models of face recognition have proposed that the names of familiar people are accessed from a lexical memory store that is distinct from the semantic memory store that holds information about such things as a familiar person's occupation and personality. Names are nevertheless retrieved via the semantic system. If such models are correct, then it should be possible for a patient to have full access to semantic information about familiar people while being unable to name many of them. We report this pattern in an anomic aphasic patient, EST, whose inability to recall the names of familiar people occurred in the context of a general word-finding problem. EST showed a preserved ability to access semantic information from familiar faces, voices, and spoken and written names and to process facial expressions, but he was unable to name many familiar faces. These findings are compatible with current models of face processing and challenge models which propose that names are stored alongside semantic information in a general-purpose long-term memory store.
