Blue Light Covers Increase Stereotypy and Decrease On-Task Behavior for Students with Autism

Abstract

Some recommended strategies for individuals with autism spectrum disorder (ASD) are not empirically based. The purpose of the study was to evaluate effects of blue light covers on levels of stereotypy and on-task behavior. Four male children with ASD who engaged in repetitive behavior participated. Placing light covers over the classroom's fluorescent lights relative to normal classroom lighting did not improve on-task behavior or stereotypy.
