A classic in its field for almost forty years, The Articulate Mammal is a brilliant introduction to psycholinguistics. In lucid prose Jean Aitchison introduces and demystifies a complex and controversial subject: What is language and is it restricted to humans? How do children acquire language so quickly? Is language innate or learned? She explains the pioneering work of Noam Chomsky; how children become acclimatized to speech rhythms before birth; the acquisition of verbs; construction and cognitive grammar; and aphasia and dementia. She also considers new topics such as language and evolution and the possibility of a 'language gene', bringing the field right up to date.
