Abstract

In the present study, two children diagnosed with autism spectrum disorder were taught to identify reflexive relations across three varying stimuli using procedures outlined in the Promoting the Emergence of Advanced Knowledge Equivalence Module (PEAK-E). Two programs from the PEAK-E module were utilized, programs 2B and 3C, both of which incorporated reflexive relations utilizing two differing sensory modalities. Visual relations were directly trained to the participants while the tactile relations were derived and monitored through probes. The same three stimuli were utilized in both PEAK-E programs for each participant; however, those three stimuli varied across participants. All stimuli were retrieved from the participants’ environments and were familiar objects to the participants. The results indicate that only one sense mode, visual, required corrective feedback and praise in order for cross-modal transfer to occur for the second sense mode, tactile. Both participants demonstrated they acquired the reflexive skills for both visual and tactile stimuli. Participant 1 reached mastery criterion for both skills in 36 trials, and participant 2 reached mastery criterion within 20 trials. Limitations and future directions for implication of cross modal transfer are discussed.
