Final answer:
The statement about self-actualization being dependent on self-acceptance refers to Maslow's hierarchy of needs, a concept from humanistic psychology emphasizing the achievement of one's full potential through the fulfillment of basic to complex needs.
Step-by-step explanation:
The statement 'Self-actualization is contingent on whether the child/adult can fully accept themselves' refers to Maslow's hierarchy of needs. Self-actualization is the highest level in Maslow's hierarchy, where an individual achieves their full potential and realizes their capacities and talents. It is rooted in the humanistic psychological theory developed by Abraham Maslow. To reach self-actualization, one must have their physiological, safety, love and belonging, and esteem needs met first. Carl Rogers, another humanistic psychologist, emphasized the importance of congruence between the ideal self (who we would like to be) and the real self (who we actually are) in contributing to self-actualization. Both Rogers's and Maslow's theories underscore the essential need for self-acceptance and congruence for a healthy, self-actualized personal growth.
