3. Hear language better
Being bilingual can lead to improved listening skills, since the brain has to work harder to distinguish different types of sounds in two or more languages (Krizman et al., 2012).
4. Become more language sensitive
Infants in bilingual households can distinguish languages they’ve never even heard before (Werker & Sebastian-Galles, 2011).
Just being exposed to the different sounds in, for example, Spanish and Catalan, helps them tell the difference between English and French is another of the benefits of learning a second language.
