Available in PDF, EPUB and Kindle. Book excerpt: Dynamic faces are highly complex, ecologically and socially relevant stimuli which we encounter almost everyday. When and what we extract from this rich source of information needs to be well coordinated by the face perception system. The current thesis investigates how this coordination is achieved. Part I comprises two psychophysical experiments examining the mechanisms underlying facial motion processing. Facial motion is represented as high-dimensional spatio-temporal data defining which part of the face is moving in which direction over time. Previous studies suggest that facial motion can be adequately represented using simple approximations. I argue against the use of synthetic facial motion by showing that the face perception system is highly sensitive towards manipulations of the natural spatio-temporal characteristics of facial motion. The neural processes coordinating facial motion processing may rely on two mechanisms: first, a sparse but meaningful spatio-temporal code representing facial motion; second, a mechanism that extracts distinctive motion characteristics. Evidence for the latter hypothesis is provided by the observation that facial motion, when performed in unconstrained contexts, helps identity judgments. Part II presents a functional magnetic resonance imaging (fMRI) study investigating the neural processing of expression and identity information in dynamic faces. Previous studies proposed a distributed neural system for face perception which distinguishes between invariant (e.g., identity) and changeable (e.g., expression) aspects of faces. Attention is a potential candidate mechanism to coordinate the processing of these two facial aspects. Two findings support this hypothesis: first, attention to expression versus identity of dynamic faces dissociates cortical areas assumed to process changeable aspects from those involved in discriminating invariant aspects of faces; second, attention leads to a more precise neural representation of the attended facial feature. Interactions between these two representations may be mediated by a part of the inferior occipital gyrus and the superior temporal sulcus which is supported by the observation that the latter area represented both expression and identity, while the first represented identity information irrespective of the attended feature.

Available in PDF, EPUB and Kindle. Book excerpt: 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 book was released on 2017-04-27 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this Research Topic was to offer an interdisciplinary forum for researchers interested in the interplay of face, eye gaze, and body perception in the understanding of others, with an emphasis on behavioural and neural processing. The papers included in this topic come from cognitive, neuroscience and social psychology perspectives and shed new light on how facial and body cues interact with each other and with social, ecological and contextual factors (such as for example social identification and group membership) to form a unified representation that can guide our perceptions and responses to other people. Altogether, they provide an up-to-date picture of advances in this fascinating research field.
Download or read book Handbook of Research on Face Processing written by A.W. Young and published by Elsevier. This book was released on 2013-10-22 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Facing the Other Novel Theories and Methods in Face Perception Research written by Davide Rivolta and published by Frontiers Media SA. This book was released on 2016-04-08 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: We rely heavily on faces during social interactions. Humans possess the ability to recognise thousands of people very quickly and accurately without effort. The serious social difficulties that follow abnormalities of the face recognition system (i.e., prosopagnosia) strongly underline the importance of typical face skills in our everyday life. Over the last fifty years, research on prosopagnosia, along with research in the healthy population, has provided insights into the cognitive and neural features behind typical face recognition. This has also been achieved thanks to non-invasive neuroimaging techniques such as functional Magnetic Resonance Imaging (fMRI), Electroencephalography (EEG), Magnetoencephalography (MEG), Diffusion Tensor Imaging (DTI) and Transcranial Magnetic Stimulation (TMS). However, there is still much debate about the cognitive and neural mechanisms of face perception. In the current “Research Topic” we plan to gather experimental works, opinions, commentaries, mini-reviews and reviews that focus on new or novel theories and methods in face perception research. Where is the field at the moment? Do we need to re-think the experimental procedures we have adopted so far? Again, what kind of techniques (or combination of them) and analysis methods will be important in the future? From the experimental point of view we encourage both behavioural and neuroimaging contributions (e.g., fMRI, EEG, MEG, DTI and TMS). Despite the main emphasis on face perception, memory and identification, we will also consider original works that focus on other aspects of face processing, such as expression recognition, attractiveness judgments and face imagery. In addition, animal investigations and experimental manipulations that alter face recognition abilities in typical human subjects (e.g., hypnosis) are also welcome. Overall, we are proposing a Research Topic that looks at face processing using different perspectives and welcome contributions from different domains such as psychology, neurology, neuroscience, cognitive science and philosophy. The current “Research Topic” evolved over the desire to acknowledge the relatively recent loss of three giants in the field: Drs. Shlomo Bentin, Truett Allison and Andy Calder. We dedicate this “Research Topic” to them and their pioneering studies.

Available in PDF, EPUB and Kindle. Book excerpt: I propose that the intermediate neural mechanisms involved in face processing may be better understood by studying concentric form-from-structure integration. This dissertation involves behavioral adaptation and masking experiments that provide evidence regarding whether face perception and concentric form-from-structure perception engage a common processing mechanism. Despite faces being complex visual stimuli, humans are able to perceive and identify faces rapidly. Studies of face perception strongly suggest that this ability involves processing the arrangement of the face features. Although high-level aspects of face perception have been studied extensively, less is known about the intermediate mechanisms involved in face processing. Converging evidence has shown that concentric form-from-structure perception involves processing the arrangement of the features and that face-sensitive mid- and high-level visual regions may be involved. I used visual adaptation and visual masking experiments to test this hypothesis. My data show that masking with, but not adaptation to, concentric form-from-structure stimuli impairs face discrimination. The results of this thesis provide evidence that concentric form-from-structure and face perception may share a common processing mechanism.

This book was released on 2012-08-21 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book follows a successful symposium organized in June 2009 at the Human Brain Mapping conference. The topic is at the crossroads of two domains of increasing importance and appeal in the neuroimaging/neuroscience community: multi-modal integration, and social neuroscience. Most of our social interactions involve combining information from both the face and voice of other persons: speech information, but also crucial nonverbal information on the person’s identity and affective state. The cerebral bases of the multimodal integration of speech have been intensively investigated; by contrast only few studies have focused on nonverbal aspects of face-voice integration. This work highlights recent advances in investigations of the behavioral and cerebral bases of face-voice multimodal integration in the context of person perception, focusing on the integration of affective and identity information. Several research domains are brought together. Behavioral and neuroimaging work in normal adult humans included are presented alongside evidence from other domains to provide complementary perspectives: studies in human children for a developmental perspective, studies in non-human primates for an evolutionary perspective, and studies in human clinical populations for a clinical perspective.

Download or read book The Oxford Handbook of Eye Movements written by Simon Liversedge and published by OUP Oxford. This book was released on 2011-08-18 with total page 1048 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past few years, there has been an explosion of eye movement research in cognitive science and neuroscience. This has been due to the availability of 'off the shelf' eye trackers, along with software to allow the easy acquisition and analysis of eye movement data. Accompanying this has been a realisation that eye movement data can be informative about many different aspects of perceptual and cognitive processing. Eye movements have been used to examine the visual and cognitive processes underpinning a much broader range of human activities, including, language production, dialogue, human computer interaction, driving behaviour, sporting performance, and emotional states. Finally, in the past thirty years, there have been real advances in our understanding of the neural processes that underpin eye movement behaviour. The Oxford Handbook of Eye Movements provides the first comprehensive review of the entire field of eye movement research. In over fifty chapters, it reviews the developments that have so far taken place, the areas actively being researched, and looks at how the field is likely to devlop in the coming years. The first section considers historical and background material, before moving onto section 2 on the neural basis of eye movements. The third and fourth sections looks at visual cognition and eye movements and eye movement pathology and development. The final sections consider eye movements and reading and language processing and eye movements. Bringing together cutting edge research from and international team of leading psychologists, neuroscientists, and vision researchers, this book is the definitive reference work in this field.

Available in PDF, EPUB and Kindle. Book excerpt: The human body has long been a rich source of inspiration for the arts, and artists have long recognized the body's special status. While the scientific study of body perception also has an important history, recent technological advances have triggered an explosion of research on the visual perception of the human body in motion, or as it is traditionally called, biological motion perception. Now reaching a point of burgeoning inter-disciplinary focus, biological motion perception research is poised to transform our understanding of person construal. Indeed, several factors highlight a privileged role for the human body as one of the most critical classes of stimuli affecting social perception. Human bodies in motion, for example, are among the most frequent moving stimulus in our environment. They can be readily perceived at a physical distance or visual vantage that precludes face perception. Moreover, body motion conveys meaningful psychological information such as social categories, emotion state, intentions, and underlying dispositions. Thus, body perception appears to serve as a first-pass filter for a vast array of social judgments from the routine (e.g., perceived friendliness in interactions) to the grave (e.g., perceived threat by law enforcement). This book provides an exciting integration of theory and findings that clarify how the human body is perceived by observers.
Download or read book The Science of Facial Expression written by José-Miguel Fernández-Dols and published by Oxford University Press. This book was released on 2017-04-14 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
