Final answer:
The Cannon-Bard theory suggests that physiological arousal and emotional experience occur simultaneously and independently, not causing one another.
Step-by-step explanation:
The Cannon-Bard theory of emotion posits that physiological arousal and emotional experience occur simultaneously and independently. This means that, when encountering an emotionally charged stimulus, such as a venomous snake, a person will experience fear at the exact same moment their body initiates a fight-or-flight response, like an increase in heart rate. Contrary to the James-Lange theory which suggests emotions arise as a result of physiological responses, the Cannon-Bard theory maintains that emotions and physiological responses co-occur but do not cause one another.
