馬斯洛需求層次理論I： 第一層次需求： 生理需求

Physiological needs are the basic animal needs for such things as food, warmth, shelter, sex, water, and other body needs. If a person is hungry or thirsty or his body is chemically unbalanced, all of his energies turn toward remedying these deficiencies, and other needs remain inactive. Maslow explains that, “Anyone who attempts to make an emergency picture into a typical one, and who will measure all of man’s goals and desires by his behavior during extreme physiological deprivation, is certainly blind to many things. It is quite true that man lives by bread alone—when there is no bread.”

The physiological needs of the organism (those enabling homeostasis) take first precedence. These consist mainly of:

1. Excretion

2. Eating

3. Sex

4. Drinking

5. Sleeping

6. Shelter

7. Warmth

If some needs are not fulfilled, a human’s physiological needs take the highest priority. Physiological needs can control thoughts and behaviors, and can cause people to feel sickness, pain, and discomfort.

馬斯洛需求層次理論II： 第二層次需求： 安全需求

With his physical needs relatively satisfied, the individual’s safety needs take over and dominate his behavior. These needs have to do with man’s yearning for a predictable, orderly world in which injustice and inconsistency are under control, the familiar frequent, and the unfamiliar rare. In the world of work, these safety needs manifest themselves in such things as a preference for job security, grievance procedures for protecting the individual from unilateral authority, savings accounts, insurance policies, and the like.

For the most part physiological and safety needs are reasonably well satisfied in our affluent and relatively lawful society. The obvious exceptions, of course, are people outside the mainstream—the poor, the disadvantaged, and members of minority groups. If frustration has not led to apathy and weakness, such people still struggle to satisfy the basic physiological and safety needs. They are primarily concerned with survival: obtaining adequate food, clothing, shelter, and seeking justice from the dominant societal groups.

馬斯洛需求層次理論III： 第三層次需求： 社會情感需求

After physiological and safety needs are fulfilled, the third layer of human needs is social. This psychological aspect of Maslow’s hierarchy involves emotionally-based relationships in general, such as: friendship, sexual intimacy, having a supportive and communicative family.

Humans need to feel a sense of belonging and acceptance, whether it comes from a large social group (such as clubs, office culture, religious groups, professional organizations, sports teams, gangs) or small social connections (family members, intimate partners, mentors, close colleagues, confidants). They need to love and be loved (sexually and non-sexually) by others. In the absence of these elements, many people become susceptible to loneliness, social anxiety, and depression. This need for belonging can often overcome the physiological and security needs, depending on the strength of the peer pressure, e.g. an anorexic ignores the need to eat and the security of health for a feeling of belonging.
