Neuropsychology

A response persists after it stops being appropriate

In neuropsychology, perseveration is the inappropriate repetition or continuation of a response (a word, action, or strategy) after it has ceased to be appropriate, typically following frontal or other brain injury. Sandson and Albert's 1984 Varieties of perseveration distinguished recurrent, stuck-in-set, and continuous forms and tied them to different lesions and mechanisms. The referent is a specific disorder of response control observed clinically and in cognitive testing, marking a failure to shift or inhibit a prior response.[1]

Unit
The inappropriate repetition or continuation of a prior response
Recovery means
Perseveration may lessen as underlying executive and attentional functions recover; it reflects impaired response control rather than a fixed trait
Measured by
Assessed by tasks such as the Wisconsin Card Sorting Test (perseverative errors) and by observation of spontaneous speech and action
