In recent literature, it is suggested that there is a bidirectional influence between a bilingual’s two languages, even in late bilinguals or second language learners (Malt et al., 2015). It is suggested that this influence is driven by the extent to which a bilingual’s languages are balanced (Bylund and Athanasopoulos, 2015). If the degree to which the converged naming pattern in bilinguals inclines toward one of the monolingual naming patterns is driven by language dominance and language proficiency, the bilinguals’ higher proficiency in Dutch could explain the higher correlation between monolingual Dutch and bilingual Dutch. If we consider bilingualism to be a continuum with one end of the scale completely balanced early simultaneous bilinguals and on the other end second language learners, it could be possible to observe convergence to a higher or lower degree modeled by language proficiency in both languages in other types of bilingualism as well.
