The Measurement of Affect, Mood, and Emotion

'... a powerful plea for a qualitative shift in the way research is conducted. It is a wise, thoughtful, and much needed guidebook for the transition from a prescientific to a scientific paradigm. If researchers read this book, they will be convinced, they will change their behavior, and their research will advance. I'm often asked to recommend a measure for emotion or mood, and I never have a simple answer. Now I do: read Ekkekakis.' James A. Russell, Boston College, from the Foreword
