Ursula Hess is Professor of Psychology at Humboldt-University zu Berlin, Germany and President of the International Society for Research on Emotion. Her research focuses on emotion communication, particularly nonverbal synchronization (mimicry) and the role of emotion expressions on impression formation. She has more than 200 scholarly publications, including five books. Reginald B. Adams, Jr. is Professor of Psychology at Penn State University, USA and a fellow of the Association for Psychological Science and the Society of Experimental Social Psychology. His research focuses on how social visual cues perceptually combine to form the unified representations that guide our impressions of and responses to others. He has more than 100 scholarly publications, including two books. Robert E. Kleck is Emeritus Professor at Dartmouth College, USA. His research has focused on the social psychological implications of physical appearance, particularly those that are stigmatizing, and more recently the interaction of facial appearance and facial expression in determining both emotional attribution and person perception outcomes.

• Preface – Communicating emotion with an aging face and body: critical issues and theoretical considerations; Part I. Basic Processes: 1. Emotion communication and person perception; 2. How social, emotional, and motivational forces affect facial appearance over time; 3. Aging bodies, brains, and emotions: the physiological hypothesis of emotional aging; Part II. Aging and Aging Stereotypes: 4. Facial Aging and its influence on facial stereotypes and trait judgments; 5. The intersection of race, gender/sex, and age in emotion perception from faces and bodies; 6. Perceived age, stereotyping, and emotion in intergenerational communication; Part III. Impact of Aging Cues on First Impressions and Emotion Communication: 7. Youth and beauty: age-based trait impressions from faces; 8. Conscious and unconscious emotion communication in intergenerational interaction; Part IV. The Effects of Facial Movement Impairment of Emotion Communication: 9. Emotional anatomy: facial expressions and botulinum toxin; 10: The expression and perception of social and emotional cues in older adults with Parkinson's disease; Part V. Methodological Approaches to the Study of the Effects of Aging on Emotion Communication: 11: Computer vision for the study of older (and younger) adult faces: Approaches, Advances, and Applications; 12: Using data-driven methods to advance knowledge of social face perception; Conclusion: the aging body – a proposal for future research.
