Research on touch and blindness has undergone rapid transformation in recent years, with dramatic developments in technology designed to provide assistance to those who are blind, and advancements in robotics that demand haptic interfaces. Touch and Blindness approaches the study of the topic from the perspectives of psychological methodology and the most sophisticated, state-of-the-art techniques in neuroscience. This book, edited by well-known leaders in the field, is derived from the discussions presented by speakers at a conference held in 2002, and presents current research in the field. The book is arranged in a logical, disciplinary fashion, first discussing touch and blindness from a psychological perspective, followed by an examination from the perspective of neuroscience. Some specific topics include: *processing spatial information from touch and movement; *form, projection, and pictures for the blind; *neural substrate and visual and tactile object representations; and *the role of visual cortex in tactile processing. Touch and Blindness is ideal for researchers in psychology and neuroscience, medicine, and special education.

A behavioral scientist explores love, belongingness, and fulfillment, focusing on how modern technology can both help and hinder our need to connect. A Next Big Idea Club nominee. Millions of people around the world are not getting the physical, emotional, and intellectual intimacy they crave. Through the wonders of modern technology, we are connecting with more people more often than ever before, but are these connections what we long for? Pandemic isolation has made us even more alone. In Out of Touch, Professor of Psychology Michelle Drouin investigates what she calls our intimacy famine, exploring love, belongingness, and fulfillment and considering why relationships carried out on technological platforms may leave us starving for physical connection. Drouin puts it this way: when most of our interactions are through social media, we are taking tiny hits of dopamine rather than the huge shots of oxytocin that an intimate in-person relationship would provide. Drouin explains that intimacy is not just sex—although of course sex is an important part of intimacy. But how important? Drouin reports on surveys that millennials (perhaps distracted by constant Tinder-swiping) have less sex than previous generations. She discusses pandemic puppies, professional cuddlers, the importance of touch, “desire discrepancy” in marriage, and the value of friendships. Online dating, she suggests, might give users too many options; and the internet facilitates “infidelity-related behaviors.” Some technological advances will help us develop and maintain intimate relationships—our phones, for example, can be bridges to emotional support. Some, on the other hand, might leave us out of touch. Drouin explores both of these possibilities.

Why we need a daily dose of touch: an investigation of the effects of touch on our physical and mental well-being. Although the therapeutic benefits of touch have become increasingly clear, American society, claims Tiffany Field, is dangerously touch-deprived. Many schools have “no touch” policies; the isolating effects of Internet-driven work and life can leave us hungry for tactile experience. In this book Field explains why we may need a daily dose of touch. The first sensory input in life comes from the sense of touch while a baby is still in the womb, and touch continues to be the primary means of learning about the world throughout infancy and well into childhood. Touch is critical, too, for adults' physical and mental health. Field describes studies showing that touch therapy can benefit everyone, from premature infants to children with asthma to patients with conditions that range from cancer to eating disorders. This second edition of Touch, revised and updated with the latest research, reports on new studies that show the role of touch in early development, in communication (including the reading of others' emotions), in personal relationships, and even in sports. It describes the physiological and biological effects of touch, including areas of the brain affected by touch, and the effects of massage therapy on prematurity, attentiveness, depression, pain, and immune functions. Touch has been shown to have positive effects on growth, brain waves, breathing, and heart rate, and to decrease stress and anxiety. As Field makes clear, we enforce our society's touch taboo at our peril.

Designed to make research on touch understandable to those not specifically involved in tactile research, this book provides broad coverage of the field. It includes material on sensory physiology and psychophysics, thermal sensibility, pain, pattern participation, sensory aids, and tactile perception in blind people. While the volume is important for researchers in the area of touch, it should also prove valuable to a broad audience of experimental and educational psychologists, and health professionals. The book should also be of interest to scientists in perception, cognition, and cognitive science, and can be used as a supplementary reader for courses in sensation and perception.

The dominance of vision is so strong in sighted people that touch is sometimes considered as a minor perceptual modality. However, touch is a powerful tool which contributes significantly to our knowledge of space and objects. Its intensive use by blind persons allows them to reach the same levels of knowledge and cognition as their sighted peers.In this book, specialized researchers present the recent state of knowledge about the cognitive functioning of touch. After an analysis of the neurophysiology and neuropsychology of touch, exploratory manual behaviors, intramodal haptic (tactual-kinesthetic) abilities and cross-modal visual-tactual coordination are examined in infants, children and adults, and in non-human primates. These studies concern both sighted and blind persons in order to know whether early visual deprivation modifies the modes of processing space and objects. The last section is devoted to the technical devices favoring the school and social integration of the young blind: Braille reading, use of raised maps and drawings, “sensory substitution” displays, and new technologies of communication adapted for the blind.

We are out of touch. Many people fear that we are trapped inside our screens, becoming less in tune with our bodies and losing our connection to the physical world. But the sense of touch has been undervalued since long before the days of digital isolation. Because of deeply rooted beliefs that favor the cerebral over the corporeal, touch is maligned as dirty or sentimental, in contrast with supposedly more elevated modes of perceiving the world. How to Feel explores the scientific, physical, emotional, and cultural aspects of touch, reconnecting us to what is arguably our most important sense. Sushma Subramanian introduces readers to the scientists whose groundbreaking research is underscoring the role of touch in our lives. Through vivid individual stories—a man who lost his sense of touch in his late teens, a woman who experiences touch-emotion synesthesia, her own efforts to become less touch averse—Subramanian explains the science of the somatosensory system and our philosophical beliefs about it. She visits labs that are shaping the textures of objects we use every day, from cereal to synthetic fabrics. The book highlights the growing field of haptics, which is trying to incorporate tactile interactions into devices such as phones that touch us back and prosthetic limbs that can feel. How to Feel offers a new appreciation for a vital but misunderstood sense and how we can use it to live more fully.
