Evaluating the function of social interaction using time allocation as a dependent measure: A replication and extension

Call et al. (2013) described a method of assessing the function of social interactions that used time allocation as a dependent measure. The current study replicated the method described by Call et al. and evaluated several extensions aimed at increasing the feasibility and efficiency of the assessment and the utility of its results. Seven children diagnosed with Autism Spectrum Disorder (ASD) participated. Social interactions were concluded to be reinforcing for 5 participants and aversive for 2 partcipants. Time allocation data for all participants are presented as well as additional analyses related to patterns of switching toward or away from social contact and session duration. Implications of this study and its methodology as well as future directions in this line of research are discussed.
