Within the framework of a scholarly and scientific approach to the study of personal peacefulness, various psychological perspectives are represented: personality, social, clinical, and positive psychology perspectives, peacefulness as nonviolence, attachment theory and the development of affect regulation, a human needs theory approach, Buddhist conceptions of compassion and mindfulness, a natural science perspective describing physiological foundations for personal peacefulness, phenomenological perspectives, and peacefulness as the promotion of conflict resolution.
