title: Tempo change during body rocking.
abstract: Occasional tempo change during spontaneous body rocking is described in two institutionalised mentally retarded children. Both acceleration and deceleration in moment-to-moment rate of body rocking were demonstrated under constant environmental conditions. The findings are discussed in relation to the automatism hypothesis of stereotyped behaviour.
