“…However, it is possible that greater transfer to more generalizable functions and performance outcomes may be possible employing combined WM training, which also includes shifting and updating functions (Koster, Hoorelbeke, Onraedt, Owens, & Derakshan, 2017). In relation to sport, it is likely that the mechanisms involved in the QE rely on the combined processes of these fundamental executive functions, whose interplay determines performance efficiency in sports (Wood, Vine, & Wilson, 2016;Wood & Furley, 2015). Specifically, the ability to maintain a steady gaze for long periods of time under high levels of pressure should not only necessitate good resistance to distraction (i.e., inhibition), but also efficient within-task attentional control (i.e., shifting) and the maintenance of accurate representations of non-fixated targets (i.e., updating).…”
