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.
