In their keynote article, Goldrick, Putnam and Schwarz (2016) present a computational account of code-mixing. Although they review literature on the co-activation of lexical representations and cognate facilitation effects in bilingual language processing, their model remains silent on how it interfaces with lexical factors, and how lexical factors impact code-switching. One such lexical factor is cognate status, which has been found to affect code-switching, as demonstrated in corpus analyses (e.g., Broersma & De Bot, 2006) and psycholinguistic experiments (Kootstra, Van Hell & Dijkstra, 2012). For example, using the structural priming technique to examine the role of lexical factors in code-switching, Kootstra et al. asked Dutch–English bilinguals to repeat a code-switched prime sentence (starting in Dutch and ending in English) and then describe a target picture by means of a code-switched sentence (also from Dutch into English). They observed that bilinguals' tendency to switch at the same position as in the prime sentence was increased when the prime sentence and target picture contained cognates.
