Speaking Multiple Languages Can Influence Children's Emotional Development, University of California, Berkeley (CAL) Study

On the classic TV show "I Love Lucy," Ricky Ricardo was known for switching into rapid-fire Spanish whenever he was upset, despite the fact Lucy had no idea what her Cuban husband was saying. These scenes were comedy gold, but they also provided a relatable portrayal of the linguistic phenomenon of code-switching. This kind of code-switching, or switching back and forth between different languages, happens all the time in multilingual environments, and often in emotional situations. In a new article in the July issue of Perspectives on Psychological Science, a journal of the Association for Psychological Science, psychological scientists Stephen Chen and Qing Zhou of the University of California, Berkeley and Morgan Kennedy of Bard College delve deeper into this linguistic phenomenon.
