Current Opinion in Neurology, 2009
This review highlights recent advances in understanding the clinical features, prevalence, and outcomes of motor stereotypy disorders in typically developing children.Longitudinal data indicate that stereotypies in children with normal intelligence show an early age of onset, chronicity, and high prevalence of comorbid difficulties, including tics ...

Functional (psychogenic) stereotypies
Journal of Neurology, 2017Functional (psychogenic) movement disorders (FMDs) may present with a broad spectrum of phenomenology including stereotypic movements. We aimed to characterize the phenomenology of functional stereotypies and compare these features with those observed in 65 patients with tardive dyskinesia (TD). From a cohort of 184 patients with FMDs, we identified 19

Schizophrenia Research, 2006
In schizophrenia, stereotypy is observed, a symptom characterized by repetitive, functionless motor behaviour. Whereas cognitive dysfunctioning is known to remain stable throughout the illness, less is known about the course of the motor symptoms. The Zeigeversuch [Mittenecker, E., 1953. Perseveration und Persönlichkeit: 1.

Research in Developmental Disabilities, 1992
The phenomena of the induction and entrainment of adjunctive behaviours was investigated in eight people with severe or profound mental retardation who exhibited stereotypic behaviours. The occurrence of collateral behaviours was investigated under extinction and massed reinforcer baselines and a variety of periodic or intermittent schedules of ...

Understanding equine stereotypies
Equine Veterinary Journal, 1999Summary It is frequently asserted that equine stereotypies, such as crib‐biting, wind‐sucking and weaving, are caused by boredom. However, this explanation is too general to be of practical use in discerning the causes of each stereotypy or in devising management practices to prevent their occurrence.

Rhythmic Habit Patterns (Stereotypies)
Developmental Medicine & Child Neurology, 1977SUMMARYRhythmic movements such as head‐rolling, head‐banging and body‐rocking are seen in normal children in early life, but much more commonly in the mentally handicapped. Emotional disturbance and boredom tend to increase the movements. Various theories have been advanced to account for these stereotyped patterns.

Stereotypy and Intermittent Reinforcement
Science, 1961Three pigeons were trained to peck at a horizontally oriented rubber strip 10 in. long. The spatial distribution of responding along this strip is found to be nonrandom when every peck is reinforced with food. The degree of nonrandomness increases markedly when the pecking is intermittently reinforced.
