This chapter aims to provide a critical overview of the methodologies related to investigating individual variables in study abroad (SA) contexts both in terms of the constructs examined and the research methods applied. We will begin by summarizing key contributions that the research related to individual variables in SA has made to understanding linguistic and personal development in this context. Following, we will address limitations and gaps in this research and its methodologies. The chapter concludes by proposing recommendations that are expected to drive the research of individual variables in SA forward.
Keywords: individual differences/variables, psychosocial individual differences, personality, motivation, beliefs, emotions, cognitive individual difference, psychosocial individual differences, working memory (WM), initial proficiency
