“…Many researchers have also examined the link between flow experience and a wide range of motivational indicators: (a) engagement (e.g., Shernoff et al, 2003 ; Steele and Fullagar, 2009 ; Valenzuela and Codina, 2014 ; Mesurado et al, 2016 ), (b) goal orientation (e.g., Schüler et al, 2010 ; Oertig et al, 2014 ), (c) achievement motives (e.g., Engeser and Rheinberg, 2008 ; Busch et al, 2013 ), (d) interest (e.g., Bressler and Bodzin, 2013 ; Bachen et al, 2016 ), and (e) volition (e.g., Schattke, 2011 ). This is not surprising because many authors (e.g., Schüler et al, 2010 ; Schattke, 2011 ; Bassi and Delle Fave, 2012 ; Fulmer and Tulis, 2016 ) consider flow experience to represent a state of optimal motivation (Deci and Ryan, 2008 ; Heutte, 2019 ).…”
