What Language Learning Demands of a Brain

Learning another language is a highly complex mental activity. It asks you to remember words, distinguish unfamiliar sounds, recognize patterns, work out grammatical rules, and retrieve the right expression at the right moment. All of that runs while you are listening, interpreting, and preparing a response. Ars Technica reports that research suggests this kind of sustained cognitive work can help keep an aging brain healthier. What makes it distinct as brain exercise is the simultaneity: several demanding processes running at once rather than one task at a time.
