The article by Gollan, Fennema-Notestine, Montoya, and Jernigan (2007, this issue) raises important issues about the, effects of bilingualism on naming test performance in older adults. In particular, proficiency in their two languages determines the ability with which older bilingual adults can name pictures in each of those languages. This observation is important if cognitive status is inferred from naming performance. In this commentary we largely endorse the arguments made by Gollan and colleagues, although we point to some limitations in their experimental design. (JINS, 2007, 13, 209–211.)
