One of the defining attributes of the human species is sophisticated communication, for which facial expressions are crucial. Traditional research has so far mainly investigated a minority of 6 basic emotional expressions displayed as pictures. Despite the important insights of this approach, its ecological validity is limited: facial movements express more than emotions, and facial expressions are more than just pictures. The objective of the present thesis is therefore to improve the understanding of facial expression recognition by investigating the internal representations of a large range of facial expressions, displayed both as static pictures and as dynamic videos. To this end, it was necessary to develop and validate a new facial expression database which includes 20.000 stimuli of 55 expressions (study 1). Perceptual representations of the six basic emotional expressions were found previously to rely on evaluation of valence and arousal; study 2 showed that this evaluation generalises to many more expressions, particularly when displayed as videos. While it is widely accepted that knowledge influences perception, how these are linked is largely unknown; study 3 investigated this question by asking how knowledge about facial expressions, instantiated as conceptual representations, relates to perceptual representations of these expressions. A strong link was found which changed with the kind of expressions and the type of display. In probably the most extensive behavioural studies (with regards to the number of facial expressions used) to date, this thesis suggests that there are commonalities but also differences in processing of emotional and of other types of facial expressions. Thus, to understand facial expression processing, one needs to consider more than the 6 basic emotional expressions. These findings outline first steps towards a new domain in facial expression research, which has implications for a number of research and application fields where facial expressions play a role, ranging from social, developmental, and clinical psychology to computer vision and affective computing research.

The importance of facial expressions has led to a steadily growing body of empirical findings and theoretical analyses. Every decade has seen work that extends or challenges previous thinking on facial expression. The Science of Facial Expression provides an updated review of the current psychology of facial expression . This book summarizes current conclusions and conceptual frameworks from leading figures who have shaped the field in their various subfields, and will therefore be of interest to practitioners, students, and researchers of emotion in cognitive psychology, neuroscience, biology, anthropology, linguistics, affective computing, and homeland security. Organized in eleven thematic sections, The Science of Facial Expression offers a broad perspective of the "geography" of the science of facial expression. It reviews the scientific history of emotion perception and the evolutionary origins and functions of facial expression. It includes an updated compilation on the great debate around Basic Emotion Theory versus Behavioral Ecology and Psychological constructionism. The developmental psychology and social psychology of facial expressions is explored in the role of facial expressions in child development, social interactions, and culture. The book also covers appraisal theory, concepts, neural and behavioral processes, and lesser-known facial behaviors such as yawing, vocal crying, and vomiting. In addition, the book reflects that research on the "expression of emotion" is moving towards a significance of context in the production and interpretation of facial expression The authors expose various fundamental questions and controversies yet to be resolved, but in doing so, open many sources of inspiration to pursue in the scientific study of facial expression.

Face perception is a highly evolved visual skills in humans. This complex ability develops across the life-span, steeply rising in infancy, refining across childhood and adolescence, reaching highest levels in adulthood and declining in old age. As such, the development of face perception comprises multiple skills, including sensory (e.g., mechanisms of holistic, configural and featural perception), cognitive (e.g., memory, processing speed, attentional control), and also emotional and social (e.g., reading and interpreting facial expression) domains. Whereas our understanding of specific functional domains involved in face perception is growing, there is further pressing demand for a multidisciplinary approach toward a more integrated view, describing how face perception ability relates to and develops with other domains of sensory and cognitive functioning. In this research topic we bring together a collection of papers that provide a shot of the current state of the art of theorizing and investigating face perception from the perspective of multiple ability domains. We would like to thank all authors for their valuable contributions that advanced our understanding of face and emotion perception across development.

Human faces are unique biological structures that convey a complex variety of important social messages. Even strangers can tell things from our faces – our feelings, our locus of attention, something of what we are saying, our age, sex and ethnic group, whether they find us attractive. In recent years there has been genuine progress in understanding how our brains derive all these different messages from faces and what can happen when one or other of the structures involved is damaged. Face Perception provides an up-to-date, integrative summary by two authors who have helped develop and shape the field over the past 30 years. It encompasses topics as diverse as the visual information our brains can exploit when we look at faces, whether prejudicial attitudes can affect how we see faces, and how people with neurodevelopmental disorders see faces. The material is digested and summarised in a way that is accessible to students, within a structure that focuses on the different things we can do with faces. It offers a compelling synthesis of behavioural, neuropsychological and cognitive neuroscience approaches to develop a distinctive point of view of the area. The book concludes by reviewing what is known about the development of face processing and re-examines the question of what makes faces ‘special’. Written in a clear and accessible style, this is invaluable reading for all students and researchers interested in studying face perception and social cognition.

Face perception is the process by which the brain and mind understand and interpret the face, particularly the human face. The face is an important site for the identification of others and conveys significant social information. Probably because of the importance of its role in social interaction, psychological processes involved in face perception are known to be present from birth, to be complex, and to involve large and widely distributed areas in the brain. These parts of the brain can be damaged to cause a specific impairment in understanding faces known as prosopagnosia. This book presents the latest research in the field.

The human face is unique among social stimuli in conveying such a variety of different characteristics. A person's identity, sex, race, age, emotional state, focus of attention, facial speech patterns, and attractiveness are all detected and interpreted with relative ease from the face. Humans also display a surprising degree of consistency in the extent to which personality traits, such as trustworthiness and likeability, are attributed to faces. In the past thirty years, face perception has become an area of major interest within psychology, with a rapidly expanding research base. Yet until now, there has been no comprehensive reference work bringing together this ever growing body of research. The Oxford Handbook of Face Perception is the most comprehensive and commanding review of the field ever published. It looks at the functional and neural mechanisms underlying the perception, representation, and interpretation of facial characteristics, such as identity, expression, eye gaze, attractiveness, personality, and race. It examines the development of these processes, their neural correlates in both human and non-human primates, congenital and acquired disorders resulting from their breakdown, and the theoretical and computational frameworks for their underlying mechanisms. With chapters by an international team of leading authorities from the brain sciences, the book is a landmark publication on face perception. For anyone looking for the definitive text on this burgeoning field, this is the essential book.

This reference work provides broad and up-to-date coverage of the major perspectives - ethological, neurobehavioral, developmental, dynamic systems, componential - on facial expression. It reviews Darwin's legacy in the theories of Izard and Tomkins and in Fridlund's recently proposed Behavioral Ecology theory. It explores continuing controversies on universality and innateness. It also updates the research guidelines of Ekman, Friesen and Ellsworth. This book anticipates emerging research questions: what is the role of culture in children's understanding of faces? In what precise ways do faces depend on the immediate context? What is the ecology of facial expression: when do different expressions occur and in what frequency? The Psychology of Facial Expressions is aimed at students, researchers and educators in psychology anthropology, and sociology who are interested in the emotive and communicative uses of facial expression.

This work explores the power of visual and vocal channels, in conveying emotional cues exploiting realistic, dynamic and mutually related emotional vocal and facial stimuli, and aims to report on a cross cultural comparison on how people from different Western Countries perceive emotional dynamic stimuli. The authors attempt to give an answer to the following questions evaluating the subjective perception of emotional states in the single (either visual or auditory channel) and the combined channels: - In a body-to-body interaction, the addressee exploits both the verbal and non-verbal communication modes to infer the speaker’s emotional state. Is such an informational content redundant? - Is the amount of information conveyed by each communication mode the same or is it different? - How much information about the speaker’s emotional state is conveyed by each mode and is there a preferential communication mode for a given emotional state? -To what extent the cultural specificity affect the decoding of the emotional information? The results are interpreted in terms of cognitive load, language expertise and stimulus dynamics. This book will be of interest to researchers and scholars in the field of Human Computer Interaction, Affective Computing, Psychology, Social Sciences .

The high degree of scientific interest in face processing is readily understandable, since people's faces provide such a wealth of social information. Moreover, investigations have produced evidence of highly precocious face processing abilities in infants, and of neural mechanisms in adults that seem to be differentially involved in face perception. Such findings demonstrate that, as one might expect, the psychological importance of the face has clear biological underpinnings. There are also urgent practical reasons for wanting to understand face processing. The most extensively investigated of these involve forensic issues. Other applications include the development of automated recognition systems for security and other purposes, and understanding and rehabilitating disorders and impairments linked to brain injuries and psychiatric conditions. Current studies of face processing are grouped in the volume into eleven topic areas. For each area, the editors approached an acknowledged authority and commissioned a review chapter summarising the findings that have been made. These chapters were then circulated to other experts who were asked to write brief commentaries that developed theoretical or empirical points of importance to each area. In this way, a balanced coverage of each topic is achieved. The book begins with a section examining the evidence suggesting that there may be something `special' about face processing. This is followed by consideration of the face as a visual pattern. Then there are four sections dealing with major uses of facial information, followed by sections discussing the development of face processing abilities and the neural mechanisms involved. The last three sections of the book deal with topics for which there are important practical applications for the studies reported.
