“…Code-switching can be observed in the speech of both low- and high-proficient bilinguals and across many language pairs (see Muysken, 2000 ; Gardner-Chloros, 2009 , for overviews), and shows the remarkable flexibility and adaptability of how people use language. Being such a pervasive phenomenon of bilingual speech, code-switching has inspired bilingualism research in many disciplines, including linguistics (e.g., Poplack, 1980 ; Muysken, 2000 ; Myers-Scotton, 2002 ; Goldrick et al, 2016 ), sociolinguistics (e.g., Blom and Gumperz, 1972 ; Myers-Scotton, 1993 ; Auer, 1998 ; Tseng and Cashman, 2015 ; Torres Cacoullos and Travis, 2016 ), psycholinguistics (e.g., Kootstra et al, 2010 , 2012 ; Hatzidaki et al, 2011 ; Green and Wei, 2014 ; Guzzardo Tamargo et al, 2016 ; Broersma et al, 2019 ), and neurocognition (e.g., Moreno et al, 2002 ; Litcofsky and Van Hell, 2017 ; Liu et al, 2018 ; Fernandez et al, 2019 ).…”
