OUP UNCORRECTED PROOF – FIRSTPROOFS, Tue Mar 04 2014, NEWGEN CHAPTER The Bilingual Brain: Language, 3 Culture, and Identity Nairán Ramírez-Esparza and Adrián García-Sierra Abstract This chapter reviews studies of the bilingual brain from a variety of disciplines, employing multiple theoretical approaches and methodologies. For example, developmental psychologists and speech and hearing scientists focus on the development of the bilingual brain in infants and children using cognitive tasks, brain measurements, and observational techniques. Linguists and educational psychologists study the impact of bilingualism on language development and in the society at large with in-depth interviews, longitudinal-observational studies, and parental reports. Social psychologists and cultural scientists investigate the effects of switching languages on thoughts and feelings utilizing self-reports, observational techniques, priming, and laboratory studies. The goal of this chapter is to provide an in-depth analysis of the fascinating world of the bilingual brain, from infancy to adulthood. Key Words: bilingualism, biculturals, cultural identity, language development, speech perception, executive control, personality, emotion, LENA Young Henry Lee stopped talking to his parents when he was twelve years old. Not because of some silly childhood tantrum, but because they asked him to. That was how it felt anyway. They asked—no, told—him to stop speaking their native Chinese. It was 1942, and they were desperate for him to learn English. “No more. Only speak your American.” The words came out in Chinglish. “I don’t understand” Henry said in English. “Hah?” his father asked. Since Henry couldn’t ask in Cantonese and his parents barely understood English, he dropped the matter, grabbed his lunch and book bag and headed down the stairs and out into the salty fishy air of Seattle’s Chinatown.
