“…Some research has failed to find evidence of bidirectional cross‐linguistic interactions, even in aspects of motion event expression (e.g., Cadierno, ; Pavlenko, ; Pavlenko & Volynsky, ). In addition, conflicting findings exist on the impact of L2 proficiency and immersion experience (e.g., Athanasopoulos, , ; Bylund & Athanasopoulos, ; Cook et al, ; versus Brown & Gullberg, , ; Chen, ; Su, ), particularly with respect to how interactions may change over the course of language development (see Stam, versus 2015; and discussion in Brown & Gullberg, ). Finally, competing models have been proposed to account for the phenomenon of convergence (see discussions in e.g., Alferink & Gullberg, ; Brown & Gullberg, ).…”
