“…2 In SLA research, on the other hand, the research examining the links between domain-specific grit and L2 achievement has shown promising results. Although the L2 studies that used a domain-general measure of grit have produced somewhat inconsistent findings (Khajavy et al, 2020;Robins, 2019;Wei et al, 2019;Yamashita, 2018), the studies that have used domain-specific grit scales have predominantly found grit as a significant, positive factor in L2 learning and teaching (e.g., Sudina & Plonsky, 2021a, 2021bSudina, Brown, et al, 2021;Sudina, Vernon, et al, 2021;Teimouri et al, 2020). Notably, the effects of domain-general grit versus domain-specific grit on L2 learning have also been scrutinized, and the findings have identified domain-specific grit as having much stronger effects on L2 learning than domain-general grit.…”
