title: Mental, motor, and social behavior of infants with cleft lip and/or cleft palate.
abstract: This is a report of analyses of cross-sectional and longitudinal samples of the mental, motor, and social behavior of children with cleft lip and/or palate as measured by the Bayley Scales for Infant Development. Seventy-five patients of the Lancaster Cleft Palate Clinic were the subjects for the sample. The longitudinal sample consisted of 28 of these Ss for whom there were complete data at 6, 12, 18, and 24 months. The results indicated that there were no significant differences in mental and motor functioning. In both analyses, the social behavior of patients with oral-facial clefts was more passive than the Bayley normative sample. The implications of these findings for future research are discussed.
