Assessing Acquisition of and Preference for Mand Topographies During Functional Communication Training.

We assessed acquisition and preference for various mand topographies in the presence of establishing operations that, historically, evoked the aggression of a child with autism. First, we implemented functional communication training (FCT) and reinforced picture exchange, iPad®, or GoTalk® activations in a multi-element format (noting differences in aggression and/or mand independence across conditions). Then, we conducted a concurrent-operant mand preference assessment. Finally, we presented assessment results to the subject's mother and asked her to indicate her own preference. Parent and subject preferences were aligned and we completed therapy using the iPad®.
