Abstract The present study characterizes changes in sustained attention ability over ages 9–14, and whether longitudinal trajectories of attention development differ between persistent ADHD, remitted ADHD and control groups. The Sustained Attention to Response Task (SART) was administered to 120 children with ADHD and 123 controls on three occasions between ages 9 and 14. Trajectories of sustained attention development, indicated by changes in SART performance (standard deviation of response time [SDRT], omission errors, and ex-Gaussian parameters sigma and tau), were examined using generalized additive mixed models. For all measures there was a significant main effect of age; response time variability and number of omission errors improved linearly as children aged. However, children with ADHD had significantly greater SDRT, tau and omission errors than controls across waves. There were no significant group differences in sigma, indicating that the greater overall response time variability (SDRT) observed in ADHD was likely driven by more intermittent long responses (larger tau). Trajectories of sustained attention performance did not differ between children with persistent ADHD or ADHD in remission. Longitudinal trajectories of sustained attention development are comparable between ADHD and controls, however children with ADHD (regardless of remission status) display a performance deficit equivalent to typical controls 1–3 years younger. Findings highlight the need for continued clinical support for children in remission from ADHD and provide support for tau as an endophenotype of ADHD. Keywords Development . Longitudinal .

Attention-deficit/hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder that can have a significant impact on an individual’s life, placing them at risk of poorer educational outcomes, decreased employment rates, and lower quality of life (Biederman and Faraone 2006; Harpin 2005; Skounti et al. 2007). Inattention is the most commonly
reported ADHD symptom across the lifespan (Brod et al. 2012). Sustained attention is a key form of inattention and is the ability to maintain focus over a prolonged period of time. It is often taxed heavily if attempting to maintain constant focus in monotonous or uninteresting tasks such as driving (Robertson and O’Connell 2010). For school children,
