stereotypy
Pronunciation: STEER-ee-oh-tie-pee
Repetitive, purposeless movements or behaviors often seen in neurodevelopmental conditions.
Full Definition
Repetitive, invariant behaviors or movements that appear to serve no obvious functional purpose and are performed in a ritualistic manner. In cognitive neurology, stereotypies can be motor (hand-flapping, rocking) or verbal (repetitive phrases or sounds) and are commonly observed in autism spectrum disorders, intellectual disabilities, and some neurodegenerative conditions. Unlike tics, stereotypies are typically longer in duration, more complex, and can often be interrupted by distraction. They may increase during periods of excitement, stress, or boredom. Stereotypies should be distinguished from compulsions, which are driven by specific thoughts or urges.
Usage
Usage note: Distinguish from tics (briefer, more sudden) and compulsions (anxiety-driven).
