“…In this vein, performance in implicit artificial grammar learning (AGL) tasks was shown to predict sentence comprehension (Misyak & Christiansen, 2012), the processing of relative-clause sentences with long-distance dependencies (Misyak, Christiansen, & Tomblin, 2010), and speech perception abilities (Conway, Bauernschmidt, Huang, & Pisoni, 2010; Conway, Karpicke, & Pisoni, 2007). Similarly, visual SL has been demonstrated to predict reading abilities in one’s first language (L1; Arciuli & Simpson, 2012), and also literacy acquisition in a second language (L2; Frost, Siegelman, Narkiss, & Afek, 2013), and auditory SL was found to predict lexical and oral language skills in L1 (Mainela-Arnold & Evans, 2014; Singh, Steven Reznick, & Xuehua, 2012; Spencer, Kaschak, Jones, & Lonigan, 2014). A second approach to the study of individual differences stems from the assumption that understanding the source of individual differences in SL holds the promise of revealing critical insight regarding the cognitive operations underlying its mechanisms, leading to deeper comprehension of what SL capacity could predict and why (see Frost, Armstrong, Siegelman, & Christiansen, 2015, for a theoretical discussion).…”
