Understanding Emotions: Physiology, Expression, and Theoretical Perspectives

Emotions are complex responses of the entire organism, encompassing physiological arousal, expressive behaviors, and conscious experiences. This overview explores why we have emotions from a Darwinian perspective and how they serve roles in communication, security, and reproductive activity. It examines physiological changes during emotional experiences, such as alterations in respiration and blood sugar levels. We also delve into facial expressions and their universality in conveying emotions. Finally, we review prominent theories of emotion, including James-Lange and Cannon-Bard, offering insights into fear, anger, happiness, and their transient nature.
