Final answer:
Diego's participation in action sports can be explained by the Schachter-Singer two-factor theory of emotion, which involves physiological arousal paired with cognitive labeling, and sublimation, which channels impulses into acceptable activities.
Step-by-step explanation:
Diego participates in action sports such as skateboarding, snowboarding, and freestyle skiing, and his friends' attribution to being a sensation-seeker might be scientifically supported by theories that tie together emotion, cognition, and physiological responses. A theory that could explain Diego's participation in action sports as a way to conquer his emotions and actions is the Schachter-Singer two-factor theory of emotion, which posits that emotions are comprised of two factors: physiological arousal and cognitive labeling.
Specifically, this theory suggests that Diego experiences physiological arousal during these sports, and the way he interprets this arousal - as excitement, challenge, or enjoyment - contributes to the emotional experience. For instance, the adrenaline rush he gets from action sports might be interpreted in a positive context, thus providing him with a sense of thrill and accomplishment.
Additionally, the concept of sublimation might also be relevant here, an ego defense mechanism that channels potentially unproductive or harmful impulses into more acceptable or noble activities, like sports. Furthermore, the idea that adrenaline-inducing activities can help manage life's other stresses aligns with findings that stressful activities can lead to mood enhancement and better stress management Le Châtelier's Principle.
