perseveration
Pronunciation: per-SEV-er-AY-shun
The involuntary repetition or continuation of a response beyond its appropriate context, often seen in neurological conditions.
Full Definition
Perseveration is a symptom characterized by the persistent repetition of words, phrases, or behaviors even when they are no longer contextually appropriate or functional. In speech-language pathology, perseveration commonly occurs in individuals with aphasia, dementia, traumatic brain injury, or other neurological conditions. It can manifest as stuck-in-set perseveration (inability to shift between tasks) or continuous perseveration (inappropriate repetition of previous responses). Speech-language pathologists assess perseveration patterns to understand underlying cognitive-linguistic deficits and develop interventions that promote cognitive flexibility and appropriate response inhibition.
Usage
Usage note: Distinguish from echolalia, which specifically involves repetition of others' speech.
