Effects of Experimental Task Demands on Joint Attention and Verbal Behavior Observed during Parent-Child Interactions

Parent-ChildTreatment outcome studies have shown direct observation measures of parent-child interaction can be particularly sensitive to changes in both parent and child behavior following intervention; however, relatively little is known about the effects specific tasks used during the observation have on the sensitivity of detecting behavior change over time.

The purpose of this study was to compare the effects of the task demands given to the parents during parentchild interaction on rates of joint attention and verbal behavior emitted by children diagnosed with autism. The task demand conditions included 1) Free Play, 2) a directive to have the child tact at least 6 items (i.e., Tacting), and 3) a directive for the parent and child to play a set of drums together (i.e., Joint Activity).

Relatively high rates of child responding to bids for joint attention were occasioned during the free play and joint activity conditions whereas relatively high rates of responding verbally were occasioned during the tacting condition. None of the three conditions evoked high rates of initiating forms of joint attention or verbal behavior.

Results suggest that the tasks used during the direct observation of parent-child interaction influence the rates of child behavior and may confound treatment outcomes.
