“…One crucial factor is the level of linguistic analysis at which L1 influence is investigated. While there is abundant evidence of L1 effects in phonetics and phonology (e.g., Flege, Munro, & MacKay, 1995;Hanulikova, Mitterer, & McQueen, 2011) and with respect to the lexicon (e.g., Dijkstra & van Heuven, 2002), there are mixed findings when it comes to morphosyntactic and discourse-level phenomena (Clahsen & Felser, 2006;Hopp, 2010;Pan, Schimke, & Felser, 2015). The fact that L1 influence seems to be more elusive in these domains can, in turn, be related to at least two potential factors.…”
