The current study utilized a multiple baseline design to teach olfactory discrimination skills to adolescent participants with autism spectrum disorders. Relational abilities among smells and causal relations were initially probed and an intervention was implemented via training and reversal testing probes using frames of distinction between stimulus depicting clean clothing (A) and worn clothing (B), causal framing to relate those odors with specific actions stimulus depicting clean clothing (A) with wearing or hanging the clothing (C) and stimulus depicting worn clothing (B) and placing the clothing in the laundry or hamper (D). Finally, these skills were tested in an applied setting when comparing clothing items that may or may not need to be laundered through the demonstrate of transformation of stimulus function in a novel setting by testing relations between clean clothing (Y) and wearing or hanging the clothing (C) and previously worn clothing( Z) and putting them in the laundry or hamper (D). The intervention was effective at establishing these relational responses for all 4 participants throughout each phase leading to the application of these responses in an applied setting with 80%-100%. Limitations and future application are discussed involving the use of cross modal stimuli in when teaching relations and broader implications of the science.
