Abraham Maslow proposed the hierarchy of needs.

Explanation:

Abraham Maslow was an American psychologist known as one of the founders and main exponents of humanistic psychology, a psychological current that postulates the existence of a basic human tendency towards mental health, which would manifest itself as a series of self-actualization search processes and self realisation. Its position is usually classified in psychology as a "third force", and is theoretically and technically located between the paradigms of behaviorism and psychoanalysis. His latest works also define him as a pioneer of humanistic psychology. Maslow's best-known theoretical development is the pyramid of needs, a model that poses a hierarchy of human needs, in which the satisfaction of the most basic or subordinate needs gives rise to the successive generation of higher or superordinate needs. However, according to Maslow, only those unmet needs generate an alteration in the behavior since a supplied need does not generate any effect by itself. Another fundamental principle of his theory is that which suggests that the only needs that are born with the individual are those of the base, that is to say, the physiological needs and that the others arise from these needs once they have been met.
