Datshiane Navanayagam speaks to two women who research what happens to our thoughts, feelings and behaviours when we speak many languages. To what extent do we have a “mother tongue” – and what happens if we stop using it? Dr Aneta Pavlenko is a Ukrainian-American linguist who looks at the emotional impact of moving between languages. Professor Núria Sebastián Gallés is a Spanish cognitive psychologist who studies bilingual toddlers and young babies.
