We collected naming data of 32 largely monolingual Dutch speaking and 30 largely monolingual French speaking adults. The Dutch speaking participants were students at the Psychology Department of the Katholieke Universiteit Leuven, and received course credits for participation. The monolingual French speaking participants were all students at the Université Catholique de Louvain and were paid for their participation. Similar to the original study, the monolingual participants had some knowledge of the other language through formal instruction at school but they did not use this language in daily activities (with the exception of two French speaking participants and two Dutch speaking participants who indicated an occasional use of the other language). None of the Dutch speaking participants considered themselves fluent in French. Of the French speaking participants, one indicated a high degree of proficiency in Dutch1 (through formal instruction), but not at the level of a native speaker.
