Face recognition is one of the most important abilities for everyday social interactions. Congenital prosopagnosia, also referred to as "face blindness", describes the innate, lifelong impairment to recognize other people by their face. About 2 % of the population is affected. This thesis aimed to investigate different aspects of face processing in prosopagnosia in order to gain a clearer picture and a better understanding of this heterogeneous impairment. In a first study, various aspects of face recognition and perception were investigated to allow for a better understanding of the nature of prosopagnosia. The results replicated previous findings and helped to resolve discrepancies between former studies. In addition, it was found that prosopagnosics show an irregular response behavior in tests for holistic face recognition. We propose that prosopagnosics either switch between strategies or respond randomly when performing these tests. In a second study, the general face recognition deficit observed in prosopagnosia was compared to face recognition deficits occurring when dealing with other-race faces. Most humans find it hard to recognize faces of an unfamiliar race, a phenomenon called the "other-race effect". The study served to investigate if there is a possible common mechanism underlying prosopagnosia and the other-race effect, as both are characterized by problems in recognizing faces. The results allowed to reject this hypothesis, and yielded new insights about similarities and dissimilarities between prosopagnosia and the other-race effect. In the last study, a possible treatment of prosopagnosia was investigated. This was based on a single case in which a prosopagnosic reported a sudden improvement of her face recognition abilities after she started a special diet. The different studies cover diverse aspects of prosopagnosia: the nature of prosopagnosia and measurement of its characteristics, comparison to other face recognition impairments, and treatment options. The results serve to broaden the knowledge about prosopagnosia and to gain a more detailed picture of this impairment.

This book provides readers with a simplified and comprehensive account of the cognitive and neural bases of face perception in humans. Faces are ubiquitous in our environment and we rely on them during social interactions. The human face processing system allows us to extract information about the identity, gender, age, mood, race, attractiveness and approachability of other people in about a fraction of a second, just by glancing at their faces. By introducing readers to the most relevant research on face recognition, this book seeks to answer the questions: “Why are humans so fast at recognizing faces?”, “Why are humans so efficient at recognizing faces?”, “Do faces represent a particular category for the human visual system?”, What makes face perception in humans so special?, “Can our face recognition system fail”?. This book presents the author’s findings on face perception during his research studies on both normal subjects and subjects with prosopagnosia, a neurological disorder characterized by the inability to recognize faces. The book describes two known forms of prosopagnosia: acquired prosopagnosia, which is the result of a brain lesion, and congenital prosopagnosia, which refers to a lifelong, developmental impairment of face recognition. Written in a comprehensive and accessible style, this book addresses both experts (cognitive scientists, psychologists, neuroscientists and computer scientists) and the general public, and aims at raising awareness for a debilitating face recognition disorder, such as prosopagnosia, which is often ignored or misdiagnosed as autism, with serious consequences for the affected persons and their families.

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.

Lifelong prosopagnosia has emerged as a key testing ground for theories of visual system organization, as well as the development and the emergence of neural specificity in the human brain. A key open issue concerns whether individuals who have lifelong prosopagnosia also experience difficulty with recognizing non-face stimuli. This volume features a thorough review of the congenital prosopagnosia literature and critical commentaries by the leading experts in the field. This book was originally published as a special issue of Cognitive Neuropsychology.

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.
