“…Ever since the late 1980s, there has been an increase in studies exploring acquisition of patterns of structured variability by adult learners (Bayley & Preston, 1996; Bayley & Regan, 2004; Howard, Mougeon, & Dewaele, 2013; Tarone, 2007). More recent sociolinguistic studies have highlighted the role of immersion (Mougeon, Rehner, & Nadasdi, 2004; Regan, 2010), stay‐abroad experiences (Howard, 2019), naturalistic exposure in immigrant settings (Schleef, 2017; Schleef, Meyerhoff, & Clark, 2011) as well as exposure to mass‐media products (Davydova, 2019b; Dion & Poplack, 2007) in approaching a native‐like ability in the usage of patterns of structured variation. Drawing on data collected from a cohort of German learners, the study reported here has tested a set of social and sociopsychological variables in order to explore how these mediate acquisition of sociolinguistic competence in learners mastering English as a foreign language.…”
