James J. Gross presents a process model of emotion regulation, distinguishing between strategies that act early (antecedent-focused) and later (response-focused) in the emotion-generative process. Two key strategies are reappraisal and suppression. Reappraisal involves changing the interpretation of a situation to reduce its emotional impact, while suppression involves inhibiting outward expressions of inner feelings. Experimental and individual-difference studies show that reappraisal is generally more effective than suppression. Reappraisal decreases emotional experience and expression, with no impact on memory, whereas suppression reduces expressive behavior but fails to decrease emotional experience and may impair memory. Suppression also increases physiological responses for both the suppressor and their social partners. Emotion regulation is crucial for well-being, as emotions influence our responses to challenges and opportunities. The study of emotion regulation has roots in psychoanalytic theory and the stress and coping tradition. Emotion regulation involves changes in the dynamics of emotional responses, including latency, rise time, magnitude, duration, and offset. It also involves changes in how response components are interrelated during an emotion. The process model of emotion regulation suggests that different strategies have different consequences. Reappraisal, an antecedent-focused strategy, decreases emotional experience and expression, while suppression, a response-focused strategy, decreases expressive behavior but does not reduce emotional experience. Reappraisal has no impact on memory, whereas suppression impairs memory and increases physiological responses. The cognitive consequences of reappraisal and suppression differ. Reappraisal is associated with better memory performance, while suppression leads to decrements in memory and confidence ratings. Reappraisal is less cognitively taxing than suppression, which requires continuous self-monitoring and self-corrective action. The social consequences of reappraisal and suppression also differ. Reappraisal is associated with positive social outcomes, while suppression is linked to negative social consequences. Suppression participants showed greater increases in blood pressure in their interaction partners, indicating that suppression can be physiologically activating in social contexts. Future research directions include broadening the measurement of psychophysiological consequences, expanding the focus to other forms of emotion regulation, linking emotion regulation to psychopathology, assessing the long-term health consequences of different strategies, and relating emotion regulation to other forms of self-regulation. The study highlights the importance of understanding the diverse consequences of emotion regulation strategies for both individual well-being and social functioning.James J.
