Quiet Eye Distinguishes Children of High and Low Motor Coordination Abilities

Abstract

Findings suggest that the ability to predict and calibrate movements based on sensory feedback may be impaired in children with movement coordination difficulties and have implications for how they are taught fundamental movement skills.

Adaptive Working Memory Training Reduces the Negative Impact of Anxiety on Competitive Motor Performance

“…Based on previous research investigating the QE in ball interception tasks (Rodrigues et al, 2002;Wilson et al, 2013) the QE period for the tennis volleying task was operationally defined as the final tracking gaze on the ball prior to the initiation of the forward swing of the racquet. A 13 tracking gaze was defined as a gaze sustained on the ball within 1° of visual angle for a minimum of 100 ms .…”

Quiet eye training facilitates visuomotor coordination in children with developmental coordination disorder

“…The qualitative 170 performance scale developed by Przysucha and Maraj (2010) was used (see Table 2), with modifications made to reflect the 171 specific nature of the catching task used in this study. The first author blindly scored the catch attempt according to the 172 adapted 11-point scale, and a second blinded researcher scored 10% of the trials to check for inter-rater reliability using the 173 inter-observer agreement method (see Wilson et al, 2013 value. Estimated effect sizes (h p 2 ) were calculated using partial eta squared and LSD post hoc tests were used to interrogate 186 significant interaction effects.…”

“…Visual target perturbation 29 studies have demonstrated the significant difficulties children with DCD experience when making predictive online 30 movement adaptations to movement trajectories (Hyde and Wilson, 2011a,b). Importantly, the deficits experienced by 31 children with DCD are most pronounced in complex, interceptive tasks (Bairstow & Laszlo, 1989;Wilmut & Wann, 2008;32 Mak, 2010), and as such there is a need for research to further examine visuomotor control and motor performance in these 33 less constrained settings using 'real-world' tasks (Wilson, Miles, Vine, & Vickers, 2013 'freezing' their elbow angles in this position throughout the catch in an attempt to reduce the degrees of freedom they have 39 to coordinate in the movement (Utley et al, 2007;Astill, 2007). In this study we investigated whether this freezing strategy is 40 driven by deficits in perception of ball flight characteristics that can be corrected through the use of QET.…”

Like a magician, he had to direct attention elsewhere, to his four teammates on the ice with him, to create the momentary distraction in order to move unnoticed into the open ice where Citation: Vickers, J.
