Concept:
Different psychological theories explain how emotions arise in response to stimuli.
James-Lange Theory: Physiological arousal occurs first, and the emotional experience follows.
Cannon-Bard Theory: Physiological arousal and emotional experience occur simultaneously.
Schachter-Singer Theory: Emotion depends on physiological arousal and cognitive interpretation.
Opponent-Process Theory: Emotions are followed by opposite emotional reactions.
Step 1: Identify the theory stating that arousal and emotion occur at the same time.}
According to the Cannon-Bard Theory, when a stimulus is perceived, the brain simultaneously triggers both physiological arousal and the emotional experience.
Therefore, the correct answer is Cannon-Bard Theory.
