Observations of parent-child play with toys are often used to assess interactions between parents and non-autistic as well as autistic children, but some research indicates that play without toys may elicit more positive interactions than play with toys. The first goal of the study was to examine whether this is true in the case of autistic preschoolers by comparing their play with their parents with versus without toys. The second goal was to compare mother- and father-child interactions. Seventy-eight autistic preschooler boys were observed interacting in counterbalanced mother- and father-child play with or without toys, and interactions were coded using the Emotional Availability scales. Results revealed that for both mothers and fathers scores on all of the EA scales in the play episode without toys were higher than scores in the episode with toys. Also, almost no differences were found between children's interactions with their mothers and fathers in both play with or without toys. Both findings broaden our understanding of the early social experiences of autistic children with their parents.
