“…Somewhat contrary, Tarone and Bigelow (2005) suggest that L1 literacy may improve L2 acquisition through an improvement in memory and metalinguistic awareness. Although there are findings that support the claim L1 illiteracy hinders learning of morphology (Vainikka & Young-Scholten, 2007; van der Craats, 2011), there are also findings that show that higher L1 metalinguistic awareness, and a conscious attempt to extract grammatical rules (both associated with literacy), may actually harm L2 learning in literate adults (Robinson, 2005; Xhafaj & Mota, 2011). It is possible that literacy aids some areas of language learning (e.g., vocabulary and maybe morphology), but hinders others (e.g., collocations and gender agreement).…”
