Stereotypical Behaviors and Handicapping Conditions in Infants and Children

Although the origin and function of stereotypical behaviors remain poorly understood, they appear to be common characteristics of both normal infants and infants with handicaps. However, there is limited information about the relative prevalence of stereotypical behaviors as a function of handicapping condition in infants and young children. This study documented the occurrence of stereotypical behaviors in young children with various handicapping conditions. The occurrence of stereotypical behaviors in young children with handicaps was rated by caregivers in early intervention programs. Most of the children in the study exhibited at least one stereotypical behavior, and some stereotypical behaviors were differentially associated with particular handicapping conditions. Children with more severe handicapping conditions exhibited stereotypical behaviors that may be indicative of central nervous system impairment.
