PURPOSE: Compare gesture use in infants with autism to infants with other developmental disabilities (DD) or typical development (TD). METHOD: Children with autism (n = 43), other DD (n = 30), and TD (n = 36) were recruited at ages 2 to 7 years. Parents provided home videotapes of children in infancy. Staff compiled video samples for two age intervals (9-12 and 15-18 months), and coded samples for frequency of social interaction (SI), behavior regulation (BR), and joint attention (JA) gestures. RESULTS: At 9-12 months, infants with autism were less likely to use JA gestures than infants with other DD or TD, and less likely to use BR gestures than infants with TD. At 15-18 months, infants with autism were less likely than infants with other DD to use SI or JA gestures, and less likely than infants with TD to use BR, SI, or JA gestures. Among infants able to use gestures, infants with autism used fewer BR gestures than those with TD at 9-12 months, and fewer JA gestures than infants with other DD or TD at 15-18 months. CONCLUSIONS: Differences in gesture use in infancy have implications for early autism screening, assessment, and intervention. |
