“…This model contends that there are three general determinants of immigrants' local language acquisition: (a) exposure, that is, the extent to which immigrants hear and read the local language, (b) incentives, that is, the advantages one can obtain by mastering the local language weighted against the costs of learning the local language, and (c) efficiency, that is, the innate abilities to learn and acquire a new language (Chiswick & Miller, 2007). Based on this model, a number of sociodemographic predictors of local language acquisition have been identified, including gender (e.g., Beiser & Hou, 2000;Kristen, Mühlau, & Schacht, 2016;Van der Slik, Van Hout, & Schepens, 2015), length of stay in the country of residence (e.g., Carliner, 2000;Van Tubergen & Kalmijn, 2005), age of arrival (e.g., Kristen et al, 2016), and premigration education level (Beiser & Hou, 2000;Hayfron, 2001;Hou & Beiser, 2006;Van Tubergen, 2010). Mental health has also been studied often among immigrants and refugees (e.g., see Fazel et al, 2005;Porter & Haslam, 2005), and good mental health has frequently been associated with better local language acquisition (Beiser & Hou, 2001;Chiswick & Miller, 2001;Van Tubergen & Kalmijn, 2005; for exceptions, see Van Niejenhuis, Van der Werf, & Otten, 2015;Van Tubergen, 2010).…”
