Children with attention-deficit/hyperactivity disorder show an altered eye movement pattern during reading
Optometry and Vision Science, 2020•journals.lww.com
PURPOSE The purpose of this study was to objectively compare the eye movement pattern
during oral reading in a group of nonmedicated children with pure ADHD and an age-
matched control group. METHODS Forty-one children, 21 children with pure ADHD (9.3±2.2
years, 15 boys) and 20 control children (9.3±2.5 years, 10 boys), orally read a standardized
text according to their age while the eye movement pattern was objectively recorded using
the Visagraph Eye Movement recording system. RESULTS The Bayesian statistical …

PURPOSE
The purpose of this study was to objectively compare the eye movement pattern during oral reading in a group of nonmedicated children with pure ADHD and an age-matched control group.
METHODS
Forty-one children, 21 children with pure ADHD (9.3±2.2 years, 15 boys) and 20 control children (9.3±2.5 years, 10 boys), orally read a standardized text according to their age while the eye movement pattern was objectively recorded using the Visagraph Eye Movement recording system.
RESULTS
The Bayesian statistical analyses revealed that children with ADHD exhibited a significantly higher number of fixations (Bayes factor 10 [BF 10]= 3.39), regressions (BF 10= 9.97), saccades in return sweeps (BF 10= 4.63), and anomalies of fixations and regressions (BF 10= 3.66) compared with controls. In addition, children with ADHD significantly showed longer reading times (BF 10= 31.29), as well as lower reading rate (BF 10= 156.74) and grade-level equivalent (BF 10= 168.24) in comparison with controls.
CONCLUSIONS
Our data showed that the nonmedicated children with pure ADHD have an altered eye movement pattern during oral reading when compared with controls, which cannot be attributable to any comorbid condition. The present outcomes may help to understand the link between ADHD and reading performance and design the most pertinent strategies to enhance the reading skills of this population.
