This emoji was part of the proprietary / non-standardized emoji set first introduced by Japanese carriers like Softbank. These emojis became part of the Apple iPhone starting in iOS 2.2 as an unlockable feature on handsets sold in English speaking countries.
Maslow's (1943, 1954) hierarchy of needs is a motivational theory in psychology comprising a five tier model of human needs, often depicted as hierarchical levels within a pyramid. Maslow stated that people are motivated to achieve certain needs and that some needs take precedence over others.
Maslow said that human beings strive for self-actualization, or realization of their full potential, once they have satisfied their more basic needs. Maslowâs hierarchy of needs theory is described on page 247. Maslow also provided his own account of the healthy human personality. Psychodynamic theories tend to be based on clinical case studies and therefore lack accounts of healthy personalities.
