 Differentiate between James Lange, Canon Bard and Schechter  Singer theory??

Emotion is often defined as a complex state of feeling that results in physical and psychological changes that influence thought and behavior. Emotionality is associated with a range of psychological phenomena, including temperament, personality , mood, and motivation. 

James Lange theory: 

• The James–Lange theory of emotion asserts that emotions arise as a result of physiological arousal —i.e., that the self-perception of changes in the body produces an emotional experience.

• According to the James–Lange theory, we experience emotions (such as fear, sadness, and happiness) only after physiological arousal (such as the fight-or-flight response) has occurred.

• According to the James-Lange theory of emotion, an external stimulus leads to a physiological reaction. Your emotional reaction depends upon how you interpret those physical reactions.

• One limitation of the James–Lange theory is that it is not known exactly what causes the changes in the body, so it is unclear whether they should be considered part of the emotion itself.

Canon Bard theory: 

• The Cannon–Bard theory of emotion was developed in response to the James-Lange theory, which proposes that emotions arise from physical arousal.

• In contrast, the Cannon–Bard theory argues that physiological arousal and emotional experience occur simultaneously, yet independently.

• According to the Cannon-Bard theory of emotion, we feel emotions and experience physiological reactions such as sweating, trembling, and muscle tension simultaneously.

• According to the Cannon–Bard theory, when you see a venomous snake, you feel fear at exactly the same time that your autonomic nervous system responds.

• According to this theory, emotional expression results from activation of the subcortical centers of the brain.

Schechter Singer theory :

• According to the Schechter–Singer theory of emotion (also known as two-factor theory), emotions are the result of the interaction between two factors: physiological arousal and cognition.

• According to the Schechter–Singer theory, physiological arousal is cognitively interpreted based on environmental context; this process culminates in emotional experience.

• The Schechter-Singer theory is a cognitive theory of emotion that suggests our thoughts are responsible for emotions.

• For example, if you were to see a venomous snake in your backyard, the Schechter–Singer theory argues that the snake would elicit a physiological response that would be cognitively labeled as fear based on the context.
