“…In recent years, SLA research has experienced an affective turn ( Pavlenko, 2013 ). Accordingly, in addition to focusing on how to initiate and sustain more self-determined types of motivation in learners, a host of SDT-related studies has examined the relationships between EFL motivation and other psychological variables and shown its significant association with student engagement (e.g., Chen and Kraklow, 2015 ; Oga-Baldwin and Nakata, 2017 ; Tsao et al, 2021 ), anxiety (e.g., Khodadady, 2013 ; Alamer and Almulhim, 2021 ), self-confidence (e.g., Lou and Noels, 2021 ), and willingness to communicate (e.g., Peng and Woodrow, 2010 ; Joe et al, 2017 ; Lin, 2019 ). However, there is a paucity of research on the relationships between self-determined motivation and positive character strengths (e.g., academic buoyancy) as well as emotions other than anxiety (e.g., boredom), which have emerged as salient topics in current SLA research.…”
