Individual Differences Research


The Ego as the Adaptive Core of the Self

William E. Kelly



Abstract

This editorial introduces Individual Differences Research, Volume 18, which explores the ego as the adaptive center of personality, linking classical ego psychology to modern research on self-regulation, resilience, and integration. Through studies on ego strength, identity, and affect regulation—including test-taking style, substance use, and nightmares—this volume traces enduring and evolving dimensions of adaptive self-functioning.
