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

Area of Science:

• Applied Behavior Analysis
• Disability Studies
• Assistive Technology

Background:

• Identifying effective reinforcers is crucial for individuals with severe multiple disabilities.
• Traditional preference assessments may pose challenges for non-verbal individuals.

Purpose of the Study:

• To replicate Fleming et al. (2010) by assessing eye gaze as a method for identifying reinforcers.
• To evaluate the efficacy of eye gaze in stimulus selection for individuals with severe multiple disabilities.

Main Methods:

• A paired-choice stimulus preference assessment utilized duration of eye gaze to measure stimulus selection.
• A reversal design reinforcer assessment tested the effectiveness of identified high- and low-preference stimuli.

Main Results:

• Eye gaze duration effectively identified preferred stimuli for all three participants.
• The study successfully replicated the findings of Fleming et al. (2010).

Conclusions:

• Eye gaze is a viable and effective method for identifying reinforcing stimuli for individuals with severe multiple disabilities.
• This non-verbal method enhances preference assessment accessibility.
