Peter Herriot 
Introduction to the Psychology of Language (PLE: Psycholinguistics) [PDF ebook] 

Originally published in 1970, this was Peter Herriot’s first book. In this objective, critical evaluation of a rapidly expanding field, Professor Herriot examines language as skilled behaviour, generative linguistics and psychology, behaviourist approaches to meaning, language acquisition and impairment, and language and thought. He stresses throughout the necessity for empirical research and for experimental verification of hypotheses; he also feels that language behaviour should be analysed in a comprehensive form, placing emphasis not only on structural aspects but also on the importance of meaning and context to any account of language. Today it can be read and enjoyed in its historical context.
