paraphasic errors
Word substitution errors in speech production, indicating language processing difficulties.
Full Definition
Paraphasic errors are specific types of word substitution mistakes that occur in spoken language, commonly seen in individuals with aphasia or other language disorders. These errors include phonemic paraphasias (sound substitutions within words), semantic paraphasias (word substitutions within the same category), and neologistic paraphasias (creation of non-words). The pattern and frequency of paraphasic errors help neuropsychologists identify the type and severity of language impairment and localize areas of brain dysfunction.
Usage
Usage note: Classify error type (semantic, phonemic, neologistic) and document frequency and contexts of occurrence.
