Given that the focus of our study is on innate psychological needs, Table A1 also classifies these theories in terms of their focus on psychological versus physiological needs and on innate versus learned needs. Three major theoretical perspectives were identified. Maslow’s (1938) hierarchy of needs theory is the most comprehensive in terms of capturing human needs—both physiological and psychological. He classifies needs in a hierarchy of five categories. From the bottom up, these are physiological (e.g., food, water), safety (e.g., security of body, family, property), love/belonging (e.g., friendship, family), esteem (e.g., a “lower” version of external esteem such as a need for status, recognition, prestige and attention, and a “higher” version of internal esteem such as a need for achievement, confidence, independence, and freedom), and self-actualization (e.g., morality, creativity).
