“…However, scholars do not agree on the best theoretical account of these regularities. Recently, an interest has emerged in evaluating the predictions of theoretical models to try to disentangle between theoretical predictions (see Blokzijl, Deuchar, & Parafita Couto, 2017;Eppler, Luescher, & Deuchar, 2017;Fairchild & Van Hell, 2017;Herring, Deuchar, Parafita Couto, & Moro Quintanilla, 2010;Parafita Couto, Boutonnet, Hoshino, Davies, Deuchar, & Thierry, 2017;Parafita Couto, Deuchar, & Fusser, 2015;Parafita Couto & Gullberg, 2017;vanden Wyngaerd, 2017). These researchers have shown that different theories account for some aspects of the observed data, but there is no overarching theory that can explain all the code-switching patterns.…”
