Which theory does her experience illustrate?

The Cannon-Bard theory argues that emotional experiences and physiological responses occur simultaneously and independently. If her emotions arose at the same time as her physical reactions, it would illustrate this theory instead. However, since her feelings stem from her bodily responses, this choice does not apply.

Schachter's two-factor theory suggests that emotions are based on physiological arousal and cognitive labeling of that arousal. While this theory includes the concept of physiological response, it emphasizes the need for cognitive interpretation, which is not the focus of her experience as described.

Terror management theory focuses on how individuals cope with the fear of death and the implications of mortality on behavior and emotional responses. This theory does not directly relate to her experience, which illustrates emotional responses stemming from physiological states rather than existential concerns.

Drive reduction theory centers around biological drives and the motivation to fulfill those drives to achieve homeostasis. This theory does not adequately capture the emotional aspect of her experience, which is more aligned with physiological responses leading to emotions.
