es it seems as if we never get what we want. But sometimes when we do get what we want, we realize that it’s not what we really want. That’s because our wants don’t always match our needs. The solution to this problem is to try to understand and satisfy our real needs.     Psychology is the scientific study of the human mind and human and animal behavior. A lot of psychological research has been done about human needs and how they should be satisfied. Studies have shown that humans have basic needs that must be consistently met. Studies have also shown that there is an order of importance in which these needs must be satisfied. An individual’s basic functional needs must be satisfied before he or she can go on and meet other more creative and self-fulfilling needs.     Abraham Harold Maslow (1908–1970) was an important psychologist who became famous for his studies regarding human needs and wants. He wrote two major works, Motivation and Personality and Toward a Psychology of Being. Maslow stressed that basic needs must first be satisfied before a person is able to be creative or function independently. He created his famous hierarchy of needs theory, which separates human needs into five layers. Each layer in the hierarchy must be satisfied before a person can proceed to the next layer. The five layers of human needs, according to Maslow, are as follows: The physiological needs The safety and security needs The love and belonging needs The esteem needs Self-actualization The Physiological Needs      The physiological needs include the basic requirements for physical survival, such as oxygen, water, protein, salt, sugar, minerals, and vitamins. Other physiological needs include a proper body temperature and pH balance, physical activity, a lack of pain, and adequate sleep. The Safety and Security Needs      These needs become relevant only after the physiological needs are largely satisfied. The person will then become increasingly interested in such things as being safe and protected and having a stable life. He or she might also begin to need structure and order. The Love and Belonging Needs      Once a person feels reasonably secure in life and has his or her basic bodily needs satisfied, he or she wants to be a part of a community or group, to have friends, and to be in loving and caring relationships. The Esteem Needs      This level of needs has two components. The first covers a person’s needs to be respected by others and achieve fame, attention, and dignity. The second component of this level of needs covers a person’s needs for self-respect, confidence, independence, and freedom. Self-Actualization      The highest level is different from the other levels in a crucial way. All the previous levels discuss needs that need to be satisfied; once they are satisfied, we no longer think about them. If we feel well fed, safe, appreciated, and confident, we don’t think about those needs anymore. But on the complex level of self-actualization, a person continues to feel this need even after he or she has achieved it. This need drives us to be the most complete people we can—to be the best that we can be.      The next time you are feeling as if something is missing from your life, think about Maslow and his theory of needs. Have you really satisfied the basic needs before trying to satisfy the higher levels of needs? Maybe you need to redefine what you are really searching for. 1   Select all the correct answers.
