“…Several studies used the LLAMA to examine the role of aptitude in ultimate L2 attainment in naturalistic settings (Abrahamsson & Hyltenstam, 2008;Forsberg-Lundell & Sandgren, 2013;Granena, 2014;Granena & Long, 2013) and showed that a high degree of aptitude is crucial in order for postadolescent learners to acquire a high level of L2 morphosyntactic proficiency. In the context of instructed language learning, performance on the LLAMA (either the entire battery or subtests thereof) has been shown to correlate with speech fluency and grammatical and lexical complexity (Saito, 2017(Saito, , 2019Saito & Hanzawa, 2016), grammatical knowledge (Yalcin & Spada, 2012; see also Hamrick, 2015), and global proficiency (Artieda & Muñoz, 2016;Larson-Hall & Dewey, 2012). Studies on bilingual development (Bylund, Abrahamsson, & Hyltenstam, 2012), heritage language acquisition (Bylund et al, 2010), and L1 attrition (Bylund & Ramirez-Galan, 2016) showed that LLAMA performance was positively correlated with L1 maintenance and development in a L2 context (but more so for childhood than adult language attriters).…”
