Using eye gaze to identify reinforcers for individuals with severe multiple disabilities

The purpose of this study was to replicate Fleming et al. (2010) by examining the use of eye gaze in identifying reinforcers for 3 individuals with severe multiple disabilities. Preference was measured in a paired-choice stimulus preference assessment using duration of eye gaze to determine stimulus selection. A subsequent reinforcer assessment used a reversal design to test the reinforcing effects of the high- and low-preference stimuli. The results replicated Fleming et al., indicating that using eye gaze as a selection method successfully identified reinforcing stimuli.
