stereotypy

A stereotypy is a repetitive or ritualistic movement, posture, or utterance. Stereotypies may be simple movements such as body rocking, or complex, such as self-caressing, crossing and uncrossing of legs, and marching in place. They are found in people with mental retardation, autism spectrum disorders, tardive dyskinesia and stereotypic movement disorder; studies have shown stereotypies associated with some types of schizophrenia. Frontotemporal dementia is also a common neurological cause of repetitive behaviors and stereotypies. Several causes have been hypothesized for stereotypy, and several treatment options are available.

Stereotypy is sometimes called stimming in autism, under the hypothesis that it self-stimulates one or more senses. Related terms include punding and tweaking to describe repetitive behavior that is a side effect of some drugs.
