Final answer:
Physiological changes can indeed increase the intensity of emotional experiences, as explained by theories such as the James-Lange and Schachter-Singer theories, which elucidate the connection between physiology and emotions.
Step-by-step explanation:
It is true that physiological changes may increase the intensity of emotional experiences. Emotional states are influenced by a combination of physiological arousal, psychological appraisal, and subjective experiences. The James-Lange theory of emotion posits that emotions occur after physiological responses to events. According to this theory, seeing a venomous snake would cause your heart to race (a physiological response), and then you would interpret these sensations as fear.
Research supports that individuals with spinal injuries, who may have a reduced ability to feel bodily changes, can still experience emotions, but with less intensity, suggesting physiological changes play a role in emotional intensity. In the Schachter-Singer two-factor theory, physiological arousal is labeled based on the context, and this cognitive appraisal contributes significantly to the emotion experienced. If physiological changes are intense, they may amplify the emotional experience.
