Final answer:
Abraham Maslow and Carl Rogers were the main contributors to the Human Relations Movement, focusing on the potential for human growth and self-actualization, responding to the more determinist psychology theories of their time.
Step-by-step explanation:
The main contributors to the Human Relations Movement in psychology were Abraham Maslow and Carl Rogers. These humanistic psychologists emphasized the growth potential of healthy individuals and the importance of achieving self-actualization. Their ideas were a response to prevailing psychological theories of the time, offering a perspective that highlighted free will, self-determination, and an individual’s innate capacity for growth. This movement was part of a broader context involving reforms in the mental health systems, advancements in social change, and addressing the psychological needs during civil rights movements.
Maslow is noted for his hierarchy of needs theory, which proposes that human beings share common needs that must be met in a certain order, with the highest need being self-actualization. Rogers contributed with his client-centered therapy, still widely used in psychotherapeutic settings. Both their theories have significantly contributed to our understanding of the self, as well as to group dynamics, action research, and movements for social change and liberation.
