Step 1: Understanding the Question:
The question asks us to arrange the sequential stages of experiencing an emotion according to the Schachter-Singer Two-Factor Theory of Emotion.
Step 2: Detailed Explanation:
• The Schachter-Singer theory proposes that emotion is the result of both physiological arousal and a cognitive label we apply to explain that arousal.
• D. Occurrence of the event in the environment: First, an external event or stimulus occurs in the environment (e.g., encountering a growling dog).
• A. Perception of the environmental event which might result in emotion: The individual notices and cognitively perceives this threatening or significant environmental event.
• C. A generalized state of bodily arousal which is perceived: This perception triggers a generalized physiological sympathetic reaction (e.g., rapid heart rate, trembling), which is consciously felt.
• B. Interpretation of the reason for the generalized arousal state: The individual looks to the environment to identify the source of their physiological arousal and cognitively labels the state (e.g., "My heart is beating because of that scary dog").
• E. Felt emotion based on reasons given for generalized arousal state: Finally, based on this cognitive attribution, the individual experiences the subjective conscious feeling of the emotion (e.g., feeling fear).
• This step-by-step cognitive-physiological process corresponds to the sequence: D $\rightarrow$ A $\rightarrow$ C $\rightarrow$ B $\rightarrow$ E.
Step 3: Final Answer:
The correct order of events according to the Schachter-Singer theory is D - A - C - B - E.
