This comprehensive text integrates cutting-edge neuroscience research and traditional psychological theories on emotions. Written in an engaging format, the book enables readers to appreciate the role emotions play in their lives. The author explores emotions at the behavioural, physiological, cognitive and neuro-functional (i.e., chemical, metabolic, and structural) levels and examines each in a broad context touching on emotion theory, regulation, development and culture among others. Providing greater insight and depth than existing books, Emotion provides a holistic and conceptual view of the field to give students a broader understanding of the mechanisms underlying emotions. The author covers past and current emotion theories, explores individual emotions and their representation in the brain, the role of emotions for behaviour and cognition, and inter-individual differences.
