CONCLUSIONS
QET‐based, ADHD
Overall, short‐term, 5‐week visuomotor training intervention based on the QE paradigm proved to be effective in improving inhibitory control and visually focused attention, but not visuospatial WM or basic, intrinsic attention in 9–12‐year‐old children with inattentive or combined type of ADHD. The probable reason for the ineffectiveness of QET on visuospatial WM is that this training stimulates other aspects of attention associated with fixation of the eyes on a target in a frontal visual field, in comparison with attention control of sequenced perception of visuospatial stimuli and cognitive processes of WM. The study demonstrated that the QET protocol, which includes instructions and video demonstration for the purpose of optimizing eye fixation on a target during the performance of targeting tasks, is acceptable and usable for children with ADHD. In psychological or educational practice, performing visuomotor tasks accompanied with the instructions that would encourage a longer and/or earlier fixation of eyes on the target or moving object could be useful to stimulate visual attention and the ability to suppress responses to unrelated or disturbing stimuli in children with ADHD. However, future research is needed to investigate the possible effects of the QET‐based intervention on a broader set of clinical symptoms of ADHD.
