Maslow’s hierarchy of needs
Abraham Maslow’s hierarchy of needs. An ordered ranking of needs, ranging from the earliest and most fundamental (e.g., physiological and safety needs) to the later and most complex (e.g., self-esteem and self-actualization). Early physiological needs compromised by food insecurity and other forms of deprivation. Early safety needs compromised by threat or adversity (Maslow, 1943).
