We describe ourselves as seeing red when angry, turning green with disgust, or flustered when excited. But how do we define emotions, comprehend their cognitive and physiological components, and understand the reasons behind our emotional experiences? The challenge in comprehending emotions lies in understanding the link between their physiological and cognitive components. This article explores one Theory that seeks to explain this connection—the Cannon-Bard theory of Emotion. We will begin with a concise definition, provide a few examples, explore critical concepts and applications, and subsequently compare Cannon-Bard’s emotion theory with another prominent viewpoint, the James-Lange Theory.
