Language acquisition is the process by which humans acquire the capacity to perceive, produce and use words to understand and communicate. This new book presents topical research in the study of language acquisition, including teaching language to Spanish students of EFL affected by ADHD; neural network created language; the use, application and challenges of MRI in a speech production study; the interaction between phonology and semantics in children's acquisition of the English plural and child maltreatment effects on language acquisition.
