This study evaluated the extent to which prompting and reinforcement increased three participants' correct selections of items following a therapist's gaze shift using a non‐concurrent multiple baseline design for two participants and an ABCD design for one participant. Results show that each participant learned to discriminate an adult's gaze direction to make a correct selection and each participant's responding generalized to selections with non‐reinforcing stimuli. Two participants also displayed the skill during probe sessions with their parents; however, the third participant required tangible reinforcement for correct selections to demonstrate the skill with a parent.
Gunby, Rapp, Bottoni, Marchese and Wu (2017) taught three children with autism spectrum disorder to follow an instructor's gaze shift to select a specific item; however, Gunby et al. used different types of prompts with each participant. To address this limitation, we used a progressive training model for increasing gaze shift for three children with autism spectrum disorder. Results show that each participant learned to follow an adult's shift in gaze to make a correct selection. In addition, two participants displayed the skill in response to a parent's gaze shift and with only social consequences; however, the third participant required verbal instruction and tangible reinforcement to demonstrate the skill outside of training sessions.
