What does a child’s ability to look where another is looking tell us about his or her early cognitive development? What does this ability—or lack thereof—tell us about a child’s language development, understanding of other’s intentions, and the emergence of autism? This volume assembles several years of research on the processing of gaze information and its relationship to early social-cognitive development in infants spanning many age groups. Gaze-Following examines how humans and non-human primates use another individual’s direction of gaze to learn about the world around them. The chapters throughout this volume address development in areas including joint attention, early non-verbal social interactions, language development, and theory of mind understanding. Offering novel insights regarding the significance of gaze-following, the editors present research from a neurological and a behavioral perspective, and compare children with and without pervasive developmental disorders. Scholars in the areas of cognitive development specifically, and developmental science more broadly, as well as clinical psychologists will be interested in the intriguing research presented in this volume.

Previous experimental research has suggested that chimpanzees may understand some of the epitemological aspects of visual perception, such as how the perceptual act of seeing can have internal mental consequences for an individual's state of knowledge. Other research suggests that chimpanzees and other nonhuman primates may understand visual perception at a simpler level; that is, they may at least understand seeing as a mental event that subjectively anchors organisms to the external world. However, these results are ambiguous and are open to several interpretations. In this Monograph, we report the results of 15 studies that were conducted with chimpanzees and preschool children to explore their knowledge about visual perception.

Although we routinely take our vision to be veridical representations of reality, in actuality we choose (albeit unwittingly) or construct what we see. By movements of the eyes, the direction of our gaze, we create meaning. The author offers a reformulation of perception and its neural underpinnings, focusing on the active nature of perception. In his investigation of active perception and its brain mechanisms, he offers the gaze as the principal paradigm for perception. He discusses the dynamic and constrained nature of perception; the complex information processing at the level of the retina; the active nature of vision; the intensive nature of representations; the gaze of others as visual stimulus; and the intentionality of vision and consciousness.

A revelatory account of the brain's capacity for change When neuroscientist Susan Barry was fifty years old, she experienced the sense of immersion in a three dimensional world for the first time. Skyscrapers on street corners appeared to loom out toward her like the bows of giant ships. Tree branches projected upward and outward, enclosing and commanding palpable volumes of space. Leaves created intricate mosaics in 3D. Barry had been cross-eyed and stereoblind since early infancy. After half a century of perceiving her surroundings as flat and compressed, on that day she saw the city of Manhattan in stereo depth for first time in her life. As a neuroscientist, she understood just how extraordinary this transformation was, not only for herself but for the scientific understanding of the human brain. Scientists have long believed that the brain is malleable only during a "critical period" in early childhood. According to this theory, Barry's brain had organized itself when she was a baby to avoid double vision - and there was no way to rewire it as an adult. But Barry found an optometrist who prescribed a little-known program of vision therapy; after intensive training, Barry was ultimately able to accomplish what other scientists and even she herself had once considered impossible. Dubbed "Stereo Sue" by renowned neurologist Oliver Sacks, Susan Barry tells her own remarkable journey and celebrates the joyous pleasure of our senses.

Recent advances in eye tracking technology will allow for a proliferation of new applications. Improvements in interactive methods using eye movement and gaze control could result in faster and more efficient human computer interfaces, benefitting users with and without disabilities. Gaze Interaction and Applications of Eye Tracking: Advances in Assistive Technologies focuses on interactive communication and control tools based on gaze tracking, including eye typing, computer control, and gaming, with special attention to assistive technologies. For researchers and practitioners interested in the applied use of gaze tracking, the book offers instructions for building a basic eye tracker from off-the-shelf components, gives practical hints on building interactive applications, presents smooth and efficient interaction techniques, and summarizes the results of effective research on cutting edge gaze interaction applications.

Gaze in Human-Robot Communication is a volume collecting recent research studying gaze behaviour in human-robot interaction (HRI). The selected articles draw inspiration from related research into gaze in human-human interaction in fields ranging from ethnography to neuroscience. The major themes of these articles include: the experimental investigation of human responses to robot gaze, the investigation of the impact of coordinating gaze acts with speech, and the development of hardware and software technologies for enabling robot gaze. This volume provides an excellent introduction to the depth and breadth of this growing research area in HRI. The highly interdisciplinary nature of the work presented should make it of interest both to robotics researchers and to researchers from other fields with an interest in the role of gaze in communication. Originally published in Interaction Studies Vol. 14:3 (2013).

From a preeminent researcher, this book looks at the key role of joint attention in both typical and atypical development. Peter C. Mundy shows that no other symptom dimension is more strongly linked to early identification and treatment of autism spectrum disorder (ASD). He synthesizes a wealth of knowledge on how joint attention develops, its neurocognitive underpinnings, and how it helps to explain the learning, language, and social-cognitive features of ASD across the lifespan. Clinical implications are explored, including reviews of cutting-edge diagnostic methods and targeted treatment approaches.

It is perhaps no exaggeration to suggest that all of what is intrinsically human experience is grounded in its shared nature. Joint attention to objects and events in the world provides the initial means whereby infants can start to share experiences with others and negotiate shared meanings. It provides a context for the development of both knowledge about the world and about others as experiencers. It plays a central role in the development of the young child's understanding of both the social and nonsocial worlds and in the development of the communicative interplay between child and adult. The first devoted to this important topic, this volume explores how joint attention first arises, its developmental course, its role in communication and social understanding, and the ways in which disruptions in joint attention may be implicated in a variety of forms of abnormal development including autism.

In this innovative book on autism and gaze from a multimodal interaction perspective, Terhi Korkiakangas examines the role of gaze in everyday situations, asking why eye contact matters, and considering the implications of this crucial question for autism. Since persons on the autism spectrum tend to use it differently and might not engage in eye contact in social situations, gaze is a crucial topic for understanding autism, yet we know surprisingly little about this topic in a real-world context, beyond psychological experiments and the research lab. Drawing on her research on authentic video-recorded social interactions, Korkiakangas shows how a multimodal interaction perspective can shed new light on gaze: what an instance of gaze does, and when, why, and for whom gaze ‘matters’, from both children on the autism spectrum and their social partners’ perspective, including teachers and parents. Grounded in the interactional tradition of conversation analysis, the multimodal interaction perspective offers a major contribution to our understanding of autism by examining communication beyond talk and linguistic resources. Communication, Gaze and Autism considers both mutual gaze and gaze aversion during talk or silence, alongside facial expressions, gestures, and other body movements, to understand what gaze is used for, and to rethink ‘eye contact’. The book includes a methodological introduction, practical tools for doing multimodal interaction research, and empirical findings. It also considers the voices of those people on the autism spectrum from the blogosphere, who suggest that eye contact has less significance for them and represents a communication difference, rather than a deficit. This book is designed for anyone with an academic, professional or personal interest in autism. It will particularly appeal to senior undergraduate and graduate students, researchers and practitioners in the fields of communication, social interaction and autism.
