What's the difference? Both Integrative and Integral Psychology present an all-encompassing holistic rather than an exclusivist or reductive approach. Both include both lower, ordinary, and spiritual or transcendent states of consciousness. Important writers in the field of integral psychology are Sri Aurobindo, Indra Sen, Haridas Chaudhuri, Brant Cortright and Ken Wilber. Although these writers' models may differ, they are all Integral. Integrative psychology does not propose one model or theory, but examines all of the existing models and theories in the context of personal and social well-being.
