Final answer:
Lazarus's cognitive-mediational theory and the Schachter-Singer cognitive arousal theory differ in the sequence of cognitive processes in the experience of emotions.
Step-by-step explanation:
Lazarus's cognitive-mediational theory differs from the Schachter-Singer cognitive arousal theory in terms of the order in which cognitive processes occur in the experience of emotions. According to Lazarus, our emotions are determined by our appraisal of the stimulus, which mediates between the stimulus and the emotional response and occurs before a cognitive label is assigned. On the other hand, the Schachter-Singer theory suggests that emotions are composed of two factors: physiological arousal and cognitive appraisal, with the cognitive appraisal occurring after the physiological arousal. Both theories emphasize the importance of cognitive processes in the experience of emotions, but they differ in the sequence of these processes.
