"Now in its third edition, this classic text provides accessible and authoritative explanations of key terms and draws on a range of disciplines from medicine to the social sciences. Using clear, unambiguous language and lively examples, the dictionary introduces the basic concepts of psychology." "This new edition is thoroughly updated and includes many new entries - particularly in the areas of health psychology and neuroscience - as well as, for the first time, short biographies of key psychologists. An extensive cross-referencing system makes this an ideal and enjoyable source of information for anyone studying psychology."--Jacket.
