Introduction to Maslow’s Hierarchy of Needs Every human being on the earth is having some needs and these needs motivate them for taking some action. Abraham Maslow put forward the Hierarchy of Needs model in 1943. Abraham Maslow is an American humanistic psychologist and he never believed that there is any impact of mechanical forces over human beings. Maslow’s Hierarchy of Needs represents many realities of human life and individual experiences. This theory allows people to understand the fact that how these basic needs of human life can motivate human beings. Today, the theory is still being used for understanding the factors like human motivation, management training and the development of a personal life. According to Maslow’s Hierarchy of Needs Motivational Model, all the needs of human beings should be satisfied. Maslow developed this theory based on his experiences with human lives, and not on the other existing psychology theories. (Chapman, 1) The basic concept behind the theory is can be stated as that the needs of human beings that remain unsatisfied keep on motivating the people. According to this theory, some lower-order needs are necessary to be satisfied before the upper-order needs. There are five types of needs that are defined in this hierarchal model. Among these, the physiological and safety needs are considered to be the lower-order needs, while the other three are termed as the higher-order needs. The needs are divided into the five categories which are given below:   * Physiological Needs: These are the very basic needs that are necessary for the survival of human beings. These needs include air, food, shelter, water, sleep and so on. These needs are necessary for the continuance of human life. These are the very basic needs, and if these needs are not fulfilled then surely the people will continue to motivate themselves for acquiring these needs. If these needs remain unsatisfied then it is not possible to attain the higher-order needs.   * Safety Needs: These include the needs that human beings want to live in a safe place – for their safety and protection from any type of hazards. Human beings want security, stability, laws, limits, orders, consistency, job, medical facilities, and safe residence and so on. When a person is having his physiological needs completed then automatically the concentration is turned towards safe and secure life. If a life of a person is not secured and he feels endangered every time then other needs will not receive any attention.   * Social Needs: When both of the lower-order needs are fulfilled, people can then attain the other higher-order needs. At this stage, the person is freed from the physical and emotional threats and harms. Then the need for social life has emerged – it includes the necessity of interacting with different people for different reasons. These needs include love, friendship, feelings, belongingness, affection, relationships and so on.   * Esteem Needs: When a person is socially involved somewhere, whether at a workplace or among friends, he feels the need of having some sort of importance and respect. The esteem needs can be further categorized into two groups; internal motivators and external motivators
