Maslow’s hierarchy of needs is a conceptualisation of the needs (or goals) that motivate human behaviour, which was proposed by the American psychologist Abraham Maslow. [ 1 ] [ 2 ] According to Maslow’s original formulation, there are five sets of basic needs that are related to each other in a hierarchy of prepotency (or strength).
However, RNA-based life may not have been the first to exist. [184] [185] Another model echoes Darwin's "warm little pond" with cycles of wetting and drying. [186] Some have proposed a timeline of more than 30 potential significant chemical events between pre-RNA world to near but before LUCA just involving RNA.
This is reflected in Maslow's hierarchy of needs and in his theory of self-actualization. Instead of focusing on what goes wrong with people, Maslow wanted to focus on human potential, and how we fulfill that potential. Maslow (1943, 1954) stated that human motivation is based on people seeking fulfillment and change through personal growth.
Abraham Maslow proposed many of his theories of human growth in the form of testable hypotheses, [30] [31] [32] and he encouraged scientists to put them to the test. Shortly after the founding of the American Association of Humanistic Psychology, its president, psychologist Sidney Jourard , began his column by declaring that "research" is a ...
Theory X and Theory Y are theories of human work motivation and management. They were created by Douglas McGregor while he was working at the MIT Sloan School of Management in the 1950s, and developed further in the 1960s. [1] McGregor's work was rooted in motivation theory alongside the works of Abraham Maslow, who created the hierarchy of needs.
Maslow states, "Self-actualizing people are gratified in all their basic needs (of belongingness, affection, respect, and self-esteem)". [2] Once a person has successfully navigated the hierarchy of needs thus satisfying all their basic needs, Maslow proposed they then travel "a path called growth motivation".
Since then, the primordial soup theory (Oparin–Haldane hypothesis) has become the foundation in the study of abiogenesis. [88] [89] [90] Although Oparin's theory became widely known only after the English version in 1936, Haldane accepted Oparin's originality and said, "I have very little doubt that Professor Oparin has the priority over me ...
Theory Z is a name for various theories of human motivation built on Douglas McGregor's Theory X and Theory Y. Theories X, Y and various versions of Z have been used in human resource management, organizational behavior, organizational communication and organizational development.
