“…Cognitive flexibility has been shown to support the development of several skills from a young age, such as creative thinking (e.g., Arán Filippetti & Krumm, 2020;Ebersbach & Hagedorn, 2011;Pan & Yu, 2018;Runco, 2004), lexical and conceptual knowledge (e.g., Blaye & Bonthoux, 2001;Blaye & Maintenant, 2008;Deák, 2003;Duvignau et al, 2007), problem solving (Clément, 2009(Clément, , 2022Gros, Thibaut, & Sander, 2020;Raynal, 2022;Zelazo & Frye, 1998), as well as many aspects of school achievement such as mathematics, reading, and literacy (e.g., Arán Filippetti & Richaud, 2017;Bull & Scerif, 2001;Gros & Gvozdic, 2022;Iacono, Gros, & Clément, 2022;Titz & Karbach, 2014;Yeniad et al, 2013). For instance, it has been suggested that cognitive flexibility development contributes to reading fluency in early readers by helping them to switch between phonological and semantic word properties (Cartwright et al, 2019).…”
