Although we can confirm the merged naming pattern in bilingual adults, these results do not give decisive information about semantic convergence in types of bilingualism other than simultaneous early bilinguals. Although we went through a considerable amount of effort to include balanced bilinguals, we were not able to find a perfectly balanced group of bilingual participants. This was also the case for the original study of Ameel et al. (2005) as shown by the very comparable proficiency estimates. Completely balanced bilinguals are quite rare, since there is almost always one language of which the presence is more dominant in daily life. As we can observe in our sample, only 8 out of 30 participants indicate an equal proficiency in both Dutch and French. The largest group of participants indicated dominance in Dutch (19 participants). At a group level the bilingual participants indicated a significantly higher degree of proficiency in Dutch than in French. We did indeed observe higher correlations between monolingual Dutch and bilingual Dutch, and between monolingual Dutch and bilingual French as shown in Figure 3E. These correlations are higher than the correlations between monolingual French and bilingual French and monolingual French and bilingual Dutch, respectively. This could very well be a reflection of the language imbalance in our group of participants and the dominance of Dutch at a group level.
