Pink Noise and a Pure Tone Both Reduce 1/f Neural Noise in Adults With Elevated ADHD Traits: A Critical Appraisal of the Moderate Brain Arousal Model

The moderate brain arousal (MBA) model posits that individuals with (elevated traits of) ADHD have lower levels of neural noise and that auditory random noise can elicit stochastic resonance (SR) and increase neural noise, which improves their cognitive performance. Indeed, research shows that auditory random noise, such as white noise, improves cognitive performance in individuals with (elevated traits of) ADHD. However, the assumptions regarding neural noise in ADHD and the requirement of SR…
