Bodily Changes in Pain, Hunger, Fear, and Rage: An Account of Recent Researches into the Function of Emotional Excitement

A scientific publication written in the early 20th century. The book examines the physiological responses accompanying intense emotional experiences such as pain, hunger, fear, and rage, drawing connections between these feelings and their effects on bodily functions. Cannon's work explores how these emotional states trigger specific alterations in digestion and other bodily systems. The opening of the text presents an introduction to the fundamental significance of emotions and their accompanying physiological changes. Cannon emphasizes the shared experiences of humans and animals in affecting behaviors, underscoring the importance of understanding how emotions influence physiological activities, especially in digestion. He outlines the organization of his research, which includes various animal studies demonstrating how emotional states can inhibit or promote digestive functions through both visceral nerve influences and the secretion of adrenal hormones. The premise is that these bodily changes are essential for survival and can provide insights into human behavior and health.
