While language aptitude and motivation are considered to be important contributors to second language (L2) attainment, two major gaps in the past research have been (1) a lack of nonlinear models stemming from a naive and tacit assumption that learning outcomes are linearly related to their predictors, and (2) a lack of unified and integrative…

Purpose: The purpose of the study is to examine how the combination of "what" (e.g., mastery- and performance-avoidance goals) and "why" (e.g., external regulation) are related to sport participant's goal attainment. To examine this phenomenon, we used achievement goal theory (AGT) and self-determination theory (SDT). Past…

Many large-scale, school-based interventions have attempted to improve academic performance through promoting students' growth mindset, defined as the belief that one's intellectual ability can increase with practice and time. However, most have shown weak to no effects. Thus, it is important to examine how growth mindset might affect retention…

Research suggests that students put more effort into language learning when they feel that it is a voluntary and self-relevant activity or they enjoy the process of mastering that language (i.e., they have a more self-determined orientation). This orientation is fostered when learners feel autonomous, competent, and related to others in their…

Mastery goals are generally considered the most adaptive achievement goals. In 2 studies, we tested whether, in line with self-determination theory, participants' experiences of autonomy support and autonomy would affect the relations between mastery goals and psychological outcomes. In Study 1 (an experiment), 117 college students, randomly…
