Ultra-Light Clay Intervention Improves Responsiveness and Initiates the Communication of Children With ASD.

The barriers to responsiveness and the initiation of communication are the two key problems encountered by children with autism spectrum disorders (ASD). Prior interventions based on behavioral reinforcement have had an obvious effect on responsive communication but a weak effect on the initiation of communication. Based on psychological development theory, we designed ultra-light clay interventions involving hands-on production or multi-interaction around key concepts and themes, teaching children about basic concepts, relationships, and logic, making abstract knowledge concrete and experience. Two studies (Study 1: = 3, one-to-one intervention; Study 2: = 8, one-to-two intervention) showed that ultra-light clay intervention improved both the initiation of and response to communication among children with ASD, but that such improvements show a peer-generalization effect in initiation communication, not in responsive communication. These findings provide a set of ultra-light clay interventions for communication in children with ASD and suggest a relationship between endogenous interventions and the initiation of communication.
