AP PSYCHOLOGY

Detailed explanation-1: -EMOTION is a set of complex reactions to stimuli involving subjective feelings, physiological arousal, and observable behavior.

Detailed explanation-2: -The most obvious signs of emotional arousal involve changes in the activity of the visceral motor (autonomic) system (see Chapter 21). Thus, increases or decreases in heart rate, cutaneous blood flow (blushing or turning pale), piloerection, sweating, and gastrointestinal motility can all accompany various emotions.

Detailed explanation-3: -It is described that in humans, emotion fundamentally involves “physiological arousal, expressive behaviors and conscious experience.”[2] There are four important theories of emotion. They are called the James-Lange theory, Cannon-Bard theory, Schachter-Singer theory and opponent process theory of emotion.

Detailed explanation-4: -Complex emotions, such as grief, regret, and jealousy, have highly variable appearances and compositions. Basic emotions, which include sadness, anger, fear, disgust, contempt, joy, and surprise, are so-called because they are associated with universally recognizable facial expressions (see image).
