This line of work represents an important advance in seeking to identify the nature of the timing-related processing abnormalities that are regularly reported in ADHD and related conditions. As recently summarized by Kofler et al. (2013; PMID 23872284), reaction time variability is robustly associated with ADHD, but this is not specific to ADHD, as other psychiatric conditions also exhibit markedly elevated response time variability. Similarly, timing abnormalities have been noted at multiple time scales in ADHD (e.g., Noreika, Falter, Rubia, 2013; PMID 23022430) which likely reflects involvement of multiple brain systems. Gilden and colleagues are focusing on a specific frequency band/temporal window, which may allow tighter specification of the neurobiological correlate. In this regard, see their most recent paper, which is not yet allowing comments (Marusich and Gilden, 2014, Neuropsychology) PMID 24708046.
