Levy, Mc Veigh, Marful and Andreson (2007) found that naming pictures in L2 impaired subsequent recall of the L1 translation words. This was interpreted as evidence for a domain-general inhibitory mechanism (RIF) underlying ﬁrst language attrition. Because this result is at odds with some previous ﬁndings and theoretical assumptions, we wanted to assess its reliability and replicate the experiment with various groups. Participants were ﬁrst shown drawings along with their labels in the non-dominant language. Afterwards, they named 75% of these drawings in their ﬁrst language or in their non-dominant language. Finally, participants' memory of all L1 words was tested through the presentation of a rhyme-cue. Recall of L1 words was better after naming pictures in the non-dominant language compared to when the picture was not named at all. This result suggests that speaking a second language protects rather than harms the memory of our ﬁrst language.
