The Psychology of Touch [PDF ebook] 

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.
