Answer:
Schacter-Singer two-factor
Explanation:
Schacter-Singer's two-factor theory suggests that in response to strong emotion, an individual first senses changes in his physiological characteristics and then the individual identifies the reason behind these symptoms, then experiences them and defines the felt emotion. For example, if the heart is beating fast and a bear is chasing the person, that emotion is fear. But tachycardia is a sign of excitement when, instead of being chased by a bear, the individual is looking to be loved. They are the same bodily responses, but different situations and emotions.
Linda's situation fits this theory, as she first felt her body shaking, her heart racing and her mouth dry, then realized that these symptoms were being triggered because she was nervous about her presentation in five minutes.
