Have you ever wondered how the language you speak shapes your understanding of the world around you? And if you speak two or more languages, how might that change the way you process information? Is your brain always thinking in multiple languages or are you toggling back and forth?In many parts of the world, multilingualism is the norm. And in the United States, the number of people who speak a language other than English has doubled in the past two decades, from just about 11% to about 22%.Dr. Viorica Marian has spent her career studying multilingual and bilingual people to better understand how their brains process information differently than their monolingual counterparts.Ira talks with Dr. Viorica Marian, professor of communication sciences and disorders and psychology at Northwestern University, and author of the book The Power of Language: How the Codes We Use to Think, Speak, and Live Transform our Minds in front of a live audience at the Studebaker Theater in Chicago, Illinois, presented with WBEZ and Mindworks. To stay updated on all things science, sign up for Science Friday's newsletters.
