Maslow's hierarchy of needs

Maslow's hierarchy of needs is a theory in psychology, proposed by Abraham Maslow in his 1943 paper A Theory of Human Motivation, which he subsequently extended to include his observations of humans' innate curiosity.

Maslow studied what he called, exemplary people such as Albert Einstein, Jane Addams, Eleanor Roosevelt, and Frederick Douglass rather than mentally ill or neurotic people, writing that "the study of crippled, stunted, immature, and unhealthy specimens can yield only a cripple psychology and a cripple philosophy." Maslow also studied the healthiest one percent of the college student population. In his book, The Farther Reaches of Human Nature, Maslow writes, "By ordinary standards of this kind of laboratory research... this simply was not research at all. My generalizations grew out of my selection of certain kinds of people. Obviously, other judges are needed."

Representations

This diagram shows Maslow's hierarchy of needs, represented as a pyramid with the more primitive needs at the bottom.

Maslow's hierarchy of needs is often depicted as a pyramid consisting of five levels: the first lower level is being associated with Physiological needs, while the top levels are termed growth needs associated with psychological needs. Deficiency needs must be met first. Once these are met, seeking to satisfy growth needs drives personal growth. The higher needs in this hierarchy only come into focus when the lower needs in the pyramid are satisfied. Once an individual has moved upwards to the next level, needs in the lower level will no longer be prioritized. If a lower set of needs is no longer being met, the individual will temporarily re-prioritize those needs by focusing attention on the unfulfilled needs, but will not permanently regress to the lower level. For instance, a businessman at the esteem level who is diagnosed with cancer will spend a great deal of time concentrating on his health (physiological needs), but will continue to value his work performance (esteem needs) and will likely return to work during periods of remission.

Deficiency needs

The first four layers of the pyramid are what Maslow called "deficiency needs" or "D-needs": if they are not met, the body gives no indication of it physically, but the individual feels anxious and tense. The deficiency needs are: survival needs, safety and security, love and belonging, and esteem.

Physiological needs

These are the basic human needs for such things as Warmth, water, and other bodily needs. If a person is hungry or thirsty or their body is chemically unbalanced, all of their 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[her] 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 (in order of importance):

• Breathing
• Drinking
• Eating
• Excretion
• humus
• Shelter

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

Safety needs

With their physical needs relatively satisfied, the individual's safety needs take over and dominate their behavior. These needs have to do with people'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 the "First World". The obvious exceptions, of course, are people outside the mainstream — the poor and the disadvantaged. 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.

Safety and Security needs include:

• Personal security from crime
• Financial security
• Health and well-being
• Safety net against accidents/illness and the adverse impacts

Social needs

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
• 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 ("Safety in numbers"), 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 Clinical depression. This need for belonging can often overcome the physiological and security needs, depending on the strength of the peer pressure; an anorexic, for example, ignores the need to eat and the security of health for a feeling of control and belonging.

Esteem needs

All humans have a need to be respected, to have self-esteem, self-respect, and to respect others. People need to engage themselves to gain recognition and have an activity or activities that give the person a sense of contribution, to feel accepted and self-valued, be it in a profession or hobby. Imbalances at this level can result in low self-esteem or inferiority complexes. People with low self-esteem need respect from others. They may seek fame or glory, which again depends on others. It may be noted, however, that many people with low self-esteem will not be able to improve their view of themselves simply by receiving fame, respect, and glory externally, but must first accept themselves internally. Psychological imbalances such as depression can also prevent one from obtaining self-esteem on both levels.

Growth needs

Though the deficiency needs may be seen as "basic", and can be met and neutralized (i.e. they stop being motivators in one's life), self-actualization and transcendence are "being" or "growth" needs (also termed "B-needs"); i.e. they are enduring motivations or drivers of behavior.

Aesthetic needs

Based on Maslow's beliefs, it is stated in the hierarchy humans need beautiful imagery or something new and aesthetically pleasing to continue towards Self-Actualization. Humans need to refresh themselves in the presence and beauty of nature while carefully absorbing and observing their surroundings to extract the beauty the world has to offer.

Criticisms

While Maslow's theory was regarded as an improvement over previous theories of personality and motivation, it had its detractors. For example, in their extensive review of research which is dependent on Maslow's theory, Wahba and Bridgewell found little evidence for the ranking of needs Maslow described, or even for the existence of a definite hierarchy at all. Conducted in 2002, a recent study forwards this line of thought, claiming that "the hierarchy of needs is nothing more than a fool's daydream; there is no possible way to classify ever-changing needs as society changes". Chilean economist and philosopher Manfred Max Neef has also argued fundamental human needs are non-hierarchical, and are ontologically universal and invariant in nature - part of the condition of being human; poverty, he argues, is the result of any one of these needs being frustrated, denied or unfulfilled.
