phonemic paraphasia
Pronunciation: fo-NEE-mik pair-ah-FAY-zee-ah
Speech error involving substitution, addition, or rearrangement of speech sounds within words, typical of Broca's aphasia.
Full Definition
Phonemic paraphasia, also known as literal paraphasia, is a type of speech error characterized by the substitution, omission, addition, or rearrangement of phonemes (speech sounds) within words. For example, a patient might say "tebel" instead of "table" or "plice" instead of "police." This error type is commonly seen in patients with Broca's aphasia, apraxia of speech, and certain types of fluent aphasia. Unlike semantic paraphasias, which involve word-level errors, phonemic paraphasias preserve the general semantic content while distorting the sound structure. Speech-language pathologists use the presence and pattern of phonemic paraphasias to help diagnose different types of aphasia and plan appropriate treatment strategies. The frequency and consistency of these errors can provide insight into the underlying neural mechanisms of the language disorder.
Usage
Usage note: Distinguish from semantic paraphasia (word substitutions) and neologisms (novel word creations). Critical for aphasia classification.
