INTRODUCTION
QET‐based, hyperactivity, hyperactivity disorder, impulsivity, ADHD
Behavioral inhibition and working memory (WM) are considered primary executive functions, which underpin the core features of attention‐deficit hyperactivity disorder (ADHD), such as inattention, hyperactivity, and impulsivity (Baddeley, The second cognitive function of interest—inhibitory control (response inhibition)—is the cognitive process of suppressing or withholding unrelated or dominant motor responses (Skogan et al., Attention is reflected in abnormalities of gaze control during tasks demanding visual attention based on the bidirectional functional linkage of attention and gaze control (Kleberg et al., Based on functional linkages between visual attention and gaze control, quiet eye training (QET) has been developed (Vickers, There is considerable support for the hypothesis that an intervention based on the QET principle could be effective for the amelioration of inhibitory control and visuospatial WM. First, attention underpinned by inhibition and embedded in WM processes (see above) can be ameliorated by QET because it provides explicit stimuli for controlled attention and gaze via the performance of goal‐directed motor tasks, as shown in studies with children (Miles et al., To our knowledge, the effectiveness of QET‐based intervention on inhibitory control and WM in children with ADHD has not yet been examined. Therefore, the aim of the study was to investigate whether this type of attention‐focused training via the performance of targeting tasks can be beneficial for enhancing inhibitory control and visuospatial WM. Based on current knowledge that inhibitory control and WM processes are functionally associated with attention that is also interconnected with gaze control, we hypothesized that the QET‐based intervention can ameliorate inhibitory control and visuospatial WM in children with ADHD.
