“…Furthermore, to the extent that variationists are often interested in social variables, L2 work in this vein also accounts for factors, such as the register and regional variants to which learners are exposed in the input (e.g., Tarone, ). This approach, applied to L2 Spanish, has led to a growing body of empirical research in the past two decades (e.g., Geeslin, ; Geeslin & Gudmestad, ; Gudmestad, ; Kanwit & Geeslin, ; Kanwit & Solon, ). An account for variation has also been beneficial in informing second language acquisition (SLA) research more generally, perhaps most importantly in methodological changes implemented over the past few decades, such as the use of multivariate analyses and the coding of linguistic variables based on L1 variationist research (Geeslin, ).…”
