Final answer:
Magda Arnold introduced the concept that cognitive appraisal influences emotional experience, followed by Stanley Schachter's two-factor theory emphasizing cognitive appraisal's role in emotion.
Explanation:
Magda Arnold was the first theorist to explore the idea that our cognitive appraisal of a situation influences the type of emotion we experience in response to that event.
The key concept of appraisal theory is that our thoughts before experiencing an emotion determine the nature of that emotion. For instance, a positive appraisal leads to more positive emotions.
Stanley Schachter, along with Jerome Singer, further expanded on this idea through the two-factor theory of emotion, emphasizing the role of cognitive appraisal in determining our emotional experience.
