Abstract
Objective: The purpose of this study was to investigate the impact of a concurrent “white noise” stimulus on selective attention in children with ADHD. Method: Participants were 33 children aged 7 to 14 years, who had been previously diagnosed with ADHD. All children completed a computer-based conjunction search task under two noise conditions: a classroom noise condition and a classroom noise + white noise condition. The white noise stimulus was sounds of rain, administered using an iPhone application called Sleep Machine. Results: There were no overall differences between conditions for target detection accuracy, mean reaction time (RT), or reaction time variability (SD). The impact of white noise on visual search depended on children’s medication status. Conclusion: White noise may improve task engagement for non-medicated children. White noise may be beneficial for task performance when used as an adjunct to medication.
