Available in PDF, EPUB and Kindle. Book excerpt: From a barrage of photons, we readily and effortlessly recognize the faces of our friends, and the familiar objects and scenes around us. However, these tasks cannot be simple for our visual systems--faces are all extremely similar as visual patterns, and objects look quite different when viewed from different viewpoints. How do our visual systems solve these problems? The contributors to this volume seek to answer this question by exploring how analytic and holistic processes contribute to our perception of faces, objects, and scenes. The role of parts and wholes in perception has been studied for a century, beginning with the debate between Structuralists, who championed the role of elements, and Gestalt psychologists, who argued that the whole was different from the sum of its parts. This is the first volume to focus on the current state of the debate on parts versus wholes as it exists in the field of visual perception by bringing together the views of the leading researchers. Too frequently, researchers work in only one domain, so they are unaware of the ways in which holistic and analytic processing are defined in different areas. The contributors to this volume ask what analytic and holistic processes are like; whether they contribute differently to the perception of faces, objects, and scenes; whether different cognitive and neural mechanisms code holistic and analytic information; whether a single, universal system can be sufficient for visual-information processing, and whether our subjective experience of holistic perception might be nothing more than a compelling illusion. The result is a snapshot of the current thinking on how the processing of wholes and parts contributes to our remarkable ability to recognize faces, objects, and scenes, and an illustration of the diverse conceptions of analytic and holistic processing that currently coexist, and the variety of approaches that have been brought to bear on the issues.

Download or read book Face Perception written by Andy Young and published by Psychology Press. This book was released on 2013-01-11 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Categorical Perception of Emotional Expressions Key Results written by Korolkova Olga and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Existing studies of the categorical perception of facial expressions give mixed results. Expected maximum of accuracy in ABX discrimination task is ill-conditioned and only partially explained by results of identification task. Additional analysis of the results of research (5 experiments, up to 500 subjects, different stimulus sets) show the following important results. 1. Categories, related to facial expressions are experiential prototypical, according to E. Rosh theory, not categories, defined by feature set. The position of the border between categories varies individually. 2. Perceptual category prototypes show the perceptual magnet effect. In discrimination task it, expressed in preferred choice of the answers, more similar to the prototype. For the pair of images (A, B) in ABX discrimination task this effect may be expressed as Kerr = (N err_B - N err_A) / (N err_A + N err_B). Here N err_A is number of error answers A and N err_B is number of error answers B. Distribution of Kerr on a row of stimulus in discrimination task is approximately slant line (significantly less than 0 on one side of row and significantly greater than 0 on other side). 3. Perceptual category prototypes may differ in perceptual magnet u201cstrengthu201d. Relative u201cstrengthu201d of the pair of prototypes may be measured directly in special variant of discrimination task.4. Discrimination task may be solved, based not only on face on the whole, but on the partial features of face. The way of processing related to analytical / holistic style of perception. 5. Morphing, as procedure of construction of transitional row of stimulus, produce stimulus, equidistant in sense of point-to-point differences between images (Pearson correlation). In the same time discrimination efficiency of stimulus related to generalized differences (global and intermediate wavelet coefficients). 6. Conditions of discrimination task are specially established to reach efficiency slightly exceeding choice level. For different participants the level of difficulty may vary. Generally, we believe, that the perception of facial expressions directed to individually specific communication signals, not universal.

Download or read book Face Recognition written by Katherine B. Leeland and published by Nova Publishers. This book was released on 2008 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Focus on Nonverbal Communication Research written by Finley R. Lewis and published by Nova Publishers. This book was released on 2007 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Often defined as communication without words, non-verbal communication (NVC) refers to all aspects of a message which are not conveyed by the literal meaning of words. Both written and spoken communication can be nonverbal. The main types of NVC are chronemics, kinesics, paralinguistics, proxemics and semiotics. Culture, gender and social status influence non-verbal communication. NVC also includes object communication and haptics or touch. Paralinguistic mechanisms include intonation, stress, rate of speech, and pauses or hesitations; non-linguistic behaviours include gestures, facial expressions, and body language, among others. This book brings forth new and important research in this field.

Available in PDF, EPUB and Kindle. Book excerpt: Previous studies indicate humans perceive faces categorically, particularly when the faces are familiar. Categorical perception is traditionally defined by positive results on two psychophysical tasks: an identification and a discrimination task. Whether nonhuman primates demonstrate the same phenomenon has not yet been explored. This study bridges this gap in the literature by exploring categorical perception of familiar and unfamiliar conspecific faces in two rhesus macaques using computer-generated morph line continua similar to those used in previous face categorization studies. Evidence of both hallmarks of categorical perception was found, demonstrating that rhesus macaques perceive conspecific faces in a categorical manner. This phenomenon becomes more distinct when one, but not both, of the conspecific faces are personally familiar to the individual. Inter-trial adaptation effects cannot account for these results. This study has laid down the behavioural foundation for future exploration of the neural underpinnings of the phenomenon known as categorical perception.

Download or read book Interactions between emotions and social context Basic clinical and non human evidence written by Maria Ruz and published by Frontiers E-books. This book was released on 2014-07-17 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emotions that we feel and also those that we perceive in others are crucial to the social functioning of both humans and non-human animals. Although the role of context has been extensively studied in basic sensory processing, its relevance for social cognition and emotional processing is little understood. In recent years, several lines of research at the behavioral and neural levels have highlighted the bidirectional interactions that take place between emotions and social context. Experienced emotions, even when incidental, bias decision-making. Remarkably, even basic emotions can be strongly influenced by situational contexts. In addition, both humans and non-human animals can use emotional expressions strategically as a means of influencing and managing the behavioral response of others in relation to specific environmental situations. Moreover, social emotions (e.g., engaged in moral judgment, empathic concern and social norms) seem to be context-dependent, which also questions a purely abstract account of emotion understanding and expression, as well as other social cognition domains. The present Research Topic of Frontiers in Human Neuroscience highlights the need for a situated approach to emotion and social cognition. We presented theoretical and empirical work at the behavioral and neural levels that contribute to our understanding of emotion within a highly contextualized social realm, and vice-versa. Relevant contributions are presented from diverse fields, including ethology, neurology, biology, cognitive and social neuroscience, and as well as psychology and neuropsychiatry. This integrated approach that entails the interaction between emotion and social context provide important new insights into the growing field of social neuroscience.
Download or read book Cognitive Neuroscience of Emotion written by Richard D. Lane and published by Oxford University Press. This book was released on 2002-04-04 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, a member of the Series in Affective Science, is a unique interdisciplinary sequence of articles on the cognitive neuroscience of emotion by some of the most well-known researchers in the area. It explores what is known about cognitive processes in emotion at the same time it reviews the processes and anatomical structures involved in emotion, determining whether there is something about emotion and its neural substrates that requires they be studied as a separate domain. Divided into four major focal points and presenting research that has been performed in the last decade, this book covers the process of emotion generation, the functions of amygdala, the conscious experience of emotion, and emotion regulation and dysregulation. Collectively, the chapters constitute a broad but selective survey of current knowledge about emotion and the brain, and they all address the close association between cognitive and emotional processes. By bringing together diverse strands of investigation with the aim of documenting current understanding of how emotion is instantiated in the brain, this book will be of use to scientists, researchers, and advanced students of psychology and neuroscience.

Available in PDF, EPUB and Kindle. Book excerpt: How do we sort the objects, people, events, and ideas in the world into their proper categories so that we may experience and interact with them? This fundamental question about human--and animal--perception and cognition is the subject of Categorical Perception, a comprehensive survey of a wide range of important research findings on the subject. The volume brings together all known examples of categorical perception, from research on humans and animals, infants and adults, in all the sense modalities: hearing, seeing, and touch. The perceptual findings are then interpreted in terms of the available cognitive and neuroscientific theories of how categorical perception is accomplished by the brain. Research on elementary perceptual and psychophysical categories is then compared with work on higher order categories such as objects, patterns, and abstract concepts. The book proceeds to an integrative view of categorization in general by exploring the most thoroughly investigated case of categorical perception--speech perception.
