Need is called the internal psychological state of a person, during which he feels a lack of something or expresses dependence on certain factors. Need is the internal causative agent of human activity and, depending on the situation, can manifest itself in different ways.
In modern science, several levels of needs are distinguished at once. For the first time this concept was depicted as a model by the scientist Maslow. He introduced the public to the pyramid, which consisted of various layers. Each layer represented a specific need, while the primary ones were at the very bottom. The higher the level, the smaller the area of the layer. This is due to the fact that people with a higher level of need are much fewer than with primary.
Primary needs
To be more precise, all people have primary needs. They are also called physiological or congenital. Regardless of where and when a person was born, he will still feel the desire to satisfy them. Deviations also occur, but these are very rare exceptions that are comparable to the disease.
Primary is the need for sleep, food and drink, sex, communication, relaxation, breathing, etc. Some of them are present from birth, some appear over time. Secondary needs appear only with age. They are also called psychological. These include the need for respect, affection, success, etc.
Often the need can be at the junction of primary and secondary. In particular, the need for communication. However, here you need to understand that without interaction with other people, without adopting experience, a person simply can not survive.
He will not know how to get food, how to properly equip a home, and so on, that is, he cannot exist. However, compared with the absolute need for sleep or food, communication fades into the background, but still it is primarily necessary.
