Comparison of two discrimination methods in teaching Chinese children with autism

They have a Voice; are we Listening?

The field of applied behavior analysis (ABA) has produced powerful changes and improvements to the lives of many. However, the field is not immune from criticism. One criticism from those outside the field is that the goal of ABA therapy is to make Autistic people appear "indistinguishable" from their peers. This paper examines "indistinguishability" and its implications by defining "indistinguishable" in behavior analytic terms, exploring how the term was used in two notable studies in the field (Lovaas, 1987, Journal of Consulting and Clinical Psychology, 55[1], 3-9; Rekers & Lovaas, 1974, Journal of Applied Behavior Analysis, 7[2], 173-190), and providing a review of the social validity and ethical implications of having "indistinguishability" as an explicit or implied goal. This is partially accomplished by incorporating concerns from the Autistic self-advocate community. We argue that the Autistic self-advocate community's concerns surrounding "indistinguishability" as a goal have a degree of legitimacy and need to be given due consideration. Suggestions for addressing these concerns in ABA degree programs and research are discussed, emphasizing the importance of considering stakeholder values, taking criticisms seriously, and making changes when necessary.

Replicating stimulus-presentation orders in discrimination training

Children with autism spectrum disorder (ASD) are taught conditional discriminations often during early intervention. Auditory-visual conditional discrimination (AVCD) training requires the presentation of multiple antecedent stimuli, and the order of stimulus presentation varies in the literature. This series of studies replicated previous literature on stimulus-presentation order in AVCD training. In Experiment 1, we compared sample-first and comparisons-first arrangements in 8 comparisons with 4 participants with ASD. For 3 participants, both presentations were efficacious. For 1 participant, the sample-first order was more likely to be efficacious. In Experiment 2, we added a sample-first-with-repetition arrangement and conducted 6 comparisons with 5 participants with ASD. Across comparisons, all 3 presentations were efficacious. Considerations for teaching AVCD to children with ASD and suggestions for further evaluation and examination of efficacy and efficiency are discussed.
