Abstract In recent years, the study of codeswitching has made great strides by leveraging a multidisciplinary approach that integrates insights from experimental psycholinguistics, corpus linguistics, cognitive psychology, neurolinguistics, and other allied fields. We provide an overview of 2 main strands of this research, focusing on the control process model of codeswitching (e.g., Green, 2018), the variable equivalence hypothesis (e.g., Torres Cacoullos, 2020), and the ways in which these accounts of codeswitching behavior intersect and complement one another. We argue that the common insight of these 2 distinct approaches is their focus on conventionalized linguistic norms at the level of the speech community. The second portion of the article sheds light on how various aspects of codeswitching experience give rise to adaptive change through bilingual phenotyping, highlighting the centrality of our mentor Judy Kroll's contributions to this research. Finally, we present a social network analysis of Judy's research publications and argue that the high degree of interconnectivity in Judy's research network, combined with the many positive community norms that she has been instrumental in establishing, have greatly benefited both the individual members of the network and the research enterprise itself.
