Increasing eye contact toward learning materials in a toddler with autism

Area of Science:

• Behavioral Psychology
• Developmental Psychology
• Clinical Psychology

Background:

• Autism Spectrum Disorder (ASD) is often characterized by deficits in social communication, including reduced eye contact.
• Limited eye contact can impede learning, task completion, and attention to environmental stimuli in individuals with ASD.
• This study focuses on a young child with ASD to investigate methods for improving eye contact during specific tasks.

Purpose of the Study:

• To investigate the impact of reinforcement on eye contact with task materials in a child with Autism Spectrum Disorder.
• To compare the effectiveness of continuous versus intermittent reinforcement schedules in increasing eye contact.
• To assess the child's engagement with puzzle assembly, object stacking, and picture viewing tasks.

Main Methods:

• A single-subject design was employed with a two-and-a-half-year-old boy diagnosed with Autism Spectrum Disorder.
• Eye contact rates toward task materials were measured under baseline, continuous reinforcement, and intermittent reinforcement conditions.
• Food reinforcers were contingent upon eye contact with task materials during reinforcement phases.

Main Results:

• Eye contact with task materials significantly increased when food reinforcers were provided compared to baseline.
• Both continuous and intermittent reinforcement schedules led to elevated rates of eye contact.
• The participant showed improved engagement across all three tasks (puzzle, stacking, pictures) under reinforcement conditions.

Conclusions:

• Food reinforcement is an effective strategy for increasing eye contact with task materials in young children with Autism Spectrum Disorder.
• Both continuous and intermittent reinforcement schedules can be successfully utilized to improve attention and task engagement.
• These findings suggest that behavioral interventions targeting eye contact can positively impact functional skills in individuals with ASD.
