Symbolic play skills are important in language acquisition and child development. Children with autism spectrum disorder (ASD) often have difficulties demonstrating such play behaviors. Imaginary objects symbolic play refers to play behavior in which children perform play actions without actual objects. Three boys with ASD (3-7 years) participated…

This research investigated whether symbolic understanding of pictures in low-functioning children with autism is mediated by iconicity and language. In Experiment 1, participants were taught novel words paired with unfamiliar pictures that varied in iconicity (black-and-white line drawings, greyscale photographs, colour line drawings, colour…

The Symbolic Play Test was given to 31 socially impaired and 29 sociable elementary grade children retarded in language comprehension, of similar intelligence (profoundly retarded to normal). Play test age and spontaneous pretend play were similar in sociable Ss but, in the socially impaired, spontaneous pretend play was lower than play test age…

The ability of 24 children with autism (ages 3-12) to comprehend pretend acts, consisting of an experimenter pouring a pretend substance from a container onto a target figure, was explored. There was no significant difference between subjects and controls in ability to identify the pretend substance, predict the actions' pretend outcome, or…

Two studies investigated the presence of precursors of symbol formation in eight autistic children (nine years old) compared to matched retarded children. Results indicated that autistic Ss could form internal images but appeared to be unable to manipulate them in a purposeful and meaningful manner. (Author/CL)

The development status of the communicatory behavior of 11 autistic children (4 to 9 years old) was assessed during free play sessions under two conditions: when teachers were present to direct the children's behavior and when teachers were absent and the children played among themselves. (Author)

This case study reports the effects of musical interaction therapy (MIT) on the social and symbolic development of a young autistic girl. MIT fosters interpersonal contact and joint attention by synchronizing live music to adult-child interactions. Results offer preliminary evidence that MIT facilitates playful joint action formats that generalize…

Findings from relevant research applying Piaget's theory to mental retardation, psychosis, and autism are reviewed. Many autistic individuals show an arrest in operative functions at the sensorimotor functions. The early arrest interferes with subsequent development of higher-level conceptual, symbolic, and social skills. (Author)
