“…Although collocation acquisition is a life-long, largely intuition-based process in L2 (Siyanova-Chanturia & Martinez, 2014;Siyanova & Schmitt, 2008), existing research on collocations has identified a number of such factors, which can be classified into two domains. The first domain includes external non-collocation-specific factors: (1) extralinguistic, such as the age of onset and offset of learning English (Granena & Long, 2013;Han, 2004;Wray, 2002); length of residence in an English-speaking country (Bardovi-Harlig & Bastos, 2011;Groom, 2009;Nesselhauf, 2005); language input and output Durrant & Schmitt, 2010;Szudarski & Carter, 2016), and psychological-affective factors of culture and motivation (Li & Schmitt, 2010;Smith, 2005;Wray, 2008); and (2) interlinguistic, such as whether English is used as the predominant language for thinking and communication (Wang & Shih, 2011;Xu, 2015), English language proficiency (Groom, 2009;Laufer & Waldman, 2011;Nizonkiza, 2012Nizonkiza, , 2015Schmitt, 2013), and interlanguage interference (Irujo, 1986;Liao, 2010;Millar, 2011;Peters, 2016;Wolter & Yamashita, 2015).…”
