The notion of need derives from the Latin word you need. As you can see by consulting the dictionary of the Royal Spanish Academy (RAE) , the term has multiple uses and meanings.
To cite a specific case that allows deepening the scope of the concept, a need arises when there is a Impossible impulse to control which leads to individual efforts moving in a certain direction. It is also used in other circumstances to describe the lack of emotional objects or affections which are essential to survive or the lack of nutritional products or primary good that cause hunger or physical imbalance of some kind.
Nor can it be remembered that this notion can serve, on certain occasions, to mention the natural process based on the urine evacuation or excretion of excrement .
The needs are typical of every living organism and consist of a sensation caused by the idea that we are missing something, whether it is material, organic or sentimental. It is one of the fundamental components in life, not only human but also of the other species, it is the need that leads living beings to mobilize in search of objectives that serve them to satisfy what they consider necessary. A tree that, before a drought, extends its roots to reach deeper, where the water is, acts on the basis of a need, in the same way that elephants travel for several days in search of water.
If one collects information related to the needs, one can verify that several scholars have organized the needs by hierarchy. The American psychologist Abraham Maslow , for example, classified them as physiological needs (group that brings together food, liquids to quench thirst, clothing and housing); security needs (obtained from protection and care systems and links), membership needs (group where affection, friendship and love appear); self-esteem needs (related to prestige, the ability to fend for oneself and the achievement of triumphs); and the self-realization needs .
Another perspective also admits the classification of needs as essential and occasional . The first, in turn, branch into quality needs (when the subject knows the generic good and adequate to meet their need) and quantity needs (When the subject can infer how much goods he will require to meet his need).
In the field of marketing , the need is related to the desire to reach a certain product or brand. Therefore, the marketing campaigns They work to activate, stimulate and provoke human needs. In this sense, marketing does not create the needs (which already exist), but rather detects them and transforms them into business opportunities.
It should be noted that there is talk of emotional needs to refer to those things that a person considers to be vital to feel comfortable with himself and his surroundings; These needs vary with age and with the characteristics of each individual and in many cases can respond to certain emotional disorders. This happens in those people who are not able to discern clearly between those things that they think they need and what they really need, sometimes it happens for example that those adults who have suffered some trauma from feeling unprotected as children, continue to look for that security they feel they lacked. In these cases, the person must perform a therapeutic treatment in order to properly discern between his needs and his perception of them.
