This is a classic edition of Geoffrey Beattie's and Andrew Ellis' influential introduction to the psychology of human language and communication, now including a new reflective introduction from the authors. Drawing on elements from many sub-disciplines, including cognitive and social psychology, psycholinguistics and neuropsychology, the book offers an approach which breaches conventional disciplinary boundaries. Exploring the diverse nature of communication, Beattie and Ellis focus on the range of human communicative channels and the variations which occur both between and within societies and cultures.
