“…Bidirectional crosslinguistic adaptation has also been found with respect to the distribution of the vowel space (Bergmann, Nota, Sprenger & Schmid, 2016;Mayr, Price & Mennen, 2012), the realization of liquids (de Leeuw, Mennen & Scobbie, 2012), rhoticity (Himmel & Kabak, 2016;Ulbrich & Ordin, 2014) and suprasegmentals (Mennen, 2004). This suggests that L1 and L2 sounds are linked at the 10 system-wide level (Chang, 2012;Mayr, Price & Mennen, 2012), a notion further supported by the fact that the perception of phonological categories in the L1 may become weakened by competing, non-overlapping L2 categories (Tamminen, Peltola, Toivonen, Kujala & Näätänen, 2013).…”
