Final answer:
The sympathetic division of the autonomic nervous system is responsible for "Fight or Flight" responses during emotional arousal. Emotions are shaped by physiological arousal and cognitive appraisal, according to Schachter and Singer's two-factor theory.
Step-by-step explanation:
During emotional arousal, the sympathetic division of the autonomic nervous system engages in "Fight or Flight" responses. The sympathetic system is responsible for various physiological responses during these emotional states, such as increasing heart rate, respiration rate, and preparing the body to deal with potential threats. Schachter and Singer's two-factor theory emphasizes the role of physiological arousal and cognitive appraisal in the experience of emotions, suggesting that different emotions can have similar physiological responses but are distinguished by our cognitive interpretation of the situation.
