Evaluating the function of social interaction for children with autism.

Several researchers have assessed whether or not social interaction is reinforcing; however, few studies have evaluated methods of assessing whether social interactions function as reinforcing, neutral, or aversive stimuli. We extend this research by evaluating a new method of assessing the function of social interaction. Twenty-one children diagnosed with Autism Spectrum Disorder (ASD) participated. Social interactions were found to function as reinforcers for 9 participants, neutral stimuli for 7 participants, and aversive stimuli for 5 participants. The method evaluated was found to be more efficient, may be more feasible, and was similarly as decisive as methods evaluated in previous research. Implications of this study and its methodology as well as future directions in this line of research are discussed.
