Abnormal behaviour in animals

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 especially in people with autism spectrum disorder and visually impaired children, and are also found in intellectual disabilities, tardive dyskinesia, and stereotypic movement disorder; however, they may also be encountered in neurotypical individuals as well. Studies have shown stereotypies to be associated with some types of schizophrenia. Frontot
