As one of the productive approaches to L2 pragmatic development, study abroad (SA) has drawn the attention of numerous researchers during the past few decades. Different factors, specifically those related to L2 learners, implicate the impact of SA on pragmatic development. The present systematic review aims to identify the roles of individual differences, including personal as well as social and cognitive variables, on the pragmatic development of L2 learners who were involved in SA programs. To this end, 39 studies from peer-reviewed journals and books published from 2000 to 2022 were scrutinized. The results revealed that a substantial amount of research has been conducted on the intersection of L2 pragmatic competence and SA. However, more studies are required to investigate the impact of learner variables on different aspects of L2 pragmatics in the SA context. The results also indicated the extent to which learner variables were analyzed in these studies and how each variable impacted the effectiveness of SA programs. In addition to the effects of learner variables, the methodological features of the studies, including the context of the studies, designs of the studies, data sources, and characteristics of the involved participants, were explored and reported. The findings contribute to the fields of L2 pragmatic acquisition and study abroad by highlighting the gaps in the literature and identifying key learner variables that can have drastic influences on learners’ outcomes.

To provide insights into a wide array of individual learner variables implicated in intercultural education in home and study abroad contexts, this study systematically reviewed the effects of such variables on the development of intercultural competence. The corpus consisted of 56 journal articles published over the past two decades (2000-2020). The purpose of this study was to explore: (a) learner variables that were described in research on intercultural competence, including, inter alia, their age, gender, first language (L1) background, proficiency level, and attitudinal orientations; (b) settings in which learners’ intercultural development was studied, including both home contexts and study abroad contexts; and (c) effects of learner variables on the development of their intercultural competence. The results of this synthesis indicate that a growing number of studies have started to document intercultural instruction in both home and study abroad contexts. They show how learner variables were considered in conducting these studies and how variation in these variables impacted the effectiveness of instruction that targeted intercultural competence. The findings can considerably broaden our understanding of both opportunities and constraints in intercultural education in terms of learner variables and in particular variables that make the most contribution to intercultural development in home and study abroad contexts.
