“…This increased focus on development demonstrates that the field is ready for a 'shift in focus towards understanding L3A more completely' (González Alonso & Rothman, 2016, p. 4). Furthermore, the L3 literature also shows an interest in a less static approach by studying the effect of interfering factors that are to some extent connected to development, such as L2 and L3 proficiency (Jaensch, 2009;Sánchez, 2014;Sánchez & Bardel, 2017), L2 exposure/L2 frequency of use (Dewaele, 2001;Hammarberg, 2009;Stadt et al, 2018) or metalinguistic knowledge attained either in the L1 or in the L2 (Sanz, 2000;Jessner, 2008;Falk, Lindqvist & Bardel, 2015;Bardel & Sánchez, 2017).…”
