We assessed the effects of age of acquisition and language exposure on the cerebral correlates of lexical retrieval in high‐proficient, early‐acquisition bilinguals. Functional MRI was used to study Spanish–Catalan bilinguals who acquired either Spanish or Catalan as a first language in the first ye...
