Anxiety, Depression, and Emotion [PDF ebook] 

This unique volume focuses on the relationship between basic research in emotion and emotional dysfunction in depression and anxiety. Each chapter is authored by a highly regarded scientist who looks at both psychological and biological implications of research relevant to psychiatrists and psychologists. And following each chapter is engaging commentary that raises questions, illuminates connections with other bodies of work, and provides points of integration across different research traditions. Topics range from stress, cognitive functioning, and personality to affective style and behavioral inhibition, and the book as a whole has significant implications for understanding and treating anxiety disorders.
