semantic paraphasia
A type of word-finding error where patients substitute semantically related words for target words.
Full Definition
Semantic paraphasia is a specific type of language error commonly observed in individuals with aphasia, particularly those with Wernicke's aphasia or anomic aphasia. Patients substitute words that are semantically related to their intended target word, such as saying 'spoon' when they mean 'fork' or 'dog' when referring to a 'cat.' These errors reflect disruption in lexical-semantic processing and word retrieval mechanisms. Unlike phonemic paraphasias, which involve sound-based errors, semantic paraphasias maintain the grammatical structure while altering meaning. The frequency and pattern of semantic paraphasias can provide important diagnostic information about the location and extent of brain damage.
Usage
Usage note: Distinguish from phonemic paraphasia in clinical documentation.
