Dynamic integration: Affect, cognition, and the self in adulthood

Positive self and emotional development is often measured by optimization of happiness, but a second aspect of positive development the ability to tolerate tension and negativity in the interest of maintaining objective representations needs to be integrated with this hedonic emphasis. The integration of these two aspects, optimization and differentiation, reflects a dynamic balance. Such integration is possible when emotional activation or arousal is moderate, but is impaired at very high levels of activation. From youth to middle adulthood, the capacity for integration increases, but later in life, limitations or poor regulation strategies foster compensatory processes that compromise integration.
