The Perception of Odors presents concisely and clearly some of the important aspects in the study of olfaction such as perception, human pheromones, and odor pollution.
The book consists of 11 detailed chapters. Chapters 1 and 2 serve as the introduction as it outlines the basic principles, historical development, and the anatomy and physiology of olfaction. A chapter on ""Psychophysics"" is included wherein it covers the history of the measurement of odors and developments in the psychophysics of smell. The following chapters deal mostly with areas of research such as odor masking, deodorization, adaptation, odor mixture, and memory. Chapter 9 tackles the relationship of smell, particularly the perception of odor, to other senses. The last two chapters discuss the possible future areas of research and problems in odor perception. This book is a valuable reference to students and researchers studying sensation and perception.
