Continuous redundant stimulation inhibits infant activity. This effect appears independent of specific experience or response history. In the present investigation, the contribution of genetic disposition to regulation of infant response to redundancy was evaluated through observation of the behavior of three sets of fraternal twins and six sets of identical twins to combinations of redundant proprioceptive and auditory stimulation. Treatment was associated with a significant decline of infant activity independent of zygosity, and when groups were compared, identical twins were significantly more concordant for behavior during and after treatment.
