“…The handful of studies that were performed in typically developing children have led to equivocal results. Chow, Koh, Davids, Button, and Rein (2014), Emanuel, Jarus, and Bart (2008), Perreault and French (2016), and van Abswoude, Nuijen, van der Kamp, and Steenbergen (2018) did not find significant differences between performance after external or internal focus of attention instructions measured both during practice (Emanuel et al, 2008;van Abswoude et al, 2018) and during retention test assessed 24-48 h after the last practice session (Chow et al, 2014;Emanuel et al, 2008;Perreault & French, 2016;van Abswoude et al, 2018). On the other hand, many studies replicated the beneficial effects of adopting an external focus of attention as measured during practice (Abdollahipour, Wulf, Psotta, & Nieto, 2015) or following retention test 24-48 h after practice (Brocken, Kal, & van der Kamp, 2016;Flores, Schild, & Chiviacowsky, 2015;Hadler, Chiviacowsky, Wulf, & Schild, 2014;Thorn, 2006).…”
