Emotions and Anxiety (PLE: Emotion) [EPUB ebook] 
New Concepts, Methods, and Applications

First published in 1976, this volume was completely new with original contributions and traces the advances in theory and research on anxiety and emotion of the previous decade. The authors examine the origins of fear, anxiety, and other emotions and consider self-report and psychophysiological approaches to the measurement of anxiety. Also considered are the effects of anxiety on the behaviour of normal and abnormal subjects, and the volume concludes with behavioural approaches to assessment and treatment of anxiety in clinical settings.
