Book Description
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.

Book Description
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.

Book Description
This series of experiments was designed to investigate ecological sequences of dynamic facial expressions. Several manipulations were performed to examine the visual system's sensitivity to dynamic in comparison to static facial expression displays. Experiment 1 investigated subjects' sensitivity to changes in the duration of a neutral expression embedded in a dynamic sequence. The sequences depicted a change in emotion from sadness to happiness (or vice versa). Both forward and backward presentation were utilized. The results showed sensitivity to subtle information associated with the presentation direction of a facial expression sequence. This proved to be independent of the type of presentation used, either real or induced. Experiment 2 was designed to screen for any possible artifacts (expressive noise) in the sequences and to establish a threshold of discriminability. The discriminability of the emotional expressions was found to be acute and judgment accuracy was approximately 100%. Nevertheless, this manipulation turned out to be sensitive to expressive noise present in the sequences suggesting that a sequence segment may, therefore, not accurately reflect the targeted emotion. Experiment 3 examined whether temporal parameters influence the perception of emotional expression. The results indicated that emotional intensity and realness judgments were only marginally affected by the speed variations. Experiment 4 compared the amount of information necessary for correctly identifying facial expressions presented either statically or dynamically. The results showed a none significant advantage of dynamic sequences over static ones only for short sequences. This suggests that after a certain amount of information is presented no further benefit is gained. The advantage of dynamic expressions may be due to the contextual information preceding the required judgment Experiment 5 explored this hypothesis via a priming paradigm. The static primes affected the ambiguous test which was judged opposite to them. Dynamic primes showed no effect. Taken together these findings caution the use of static material in postulating underlying perceptual mechanisms associated with emotional facial. This series of experiments supports the ecological perspective by showing that dynamic facial expressions contain relevant veridical contextual information which, as opposed to static facial expressions, is relatively immune to non veridical contextual influence.

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
This book is the first to offer an overview of the increasingly studied field of face perception. Experimental and pathological dissociation methods are used to understand both the precise cognitive mechanisms and the cerebral functions involved in face perception. Three main areas of investigation are discussed: face processing after brain damage; lateral differences for face processing in normals; neuropsychological studies on facial expressions.
