title: Rhythmic habit patterns (stereotypies).
abstract: Rhythmic 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. They appear to be intentional and may satisfy some inner need or allay frustations, but it is concluded that their true significance is unknown.
