"Figure 2 . Maslow’s Motivation Model Maslow's hierarchy of needs is a theory in psychology proposed by Abraham Maslow in his 1943 paper \"A Theory of Human Motivation\" in Psychological Review . Maslow used the terms \"physiological\", \"safety\", \"belonging\" and \"love\", \"esteem\", \"self - actu alization\", and \"self - transcendence\" to describe the pattern that human motivations generally move through. The goal of Maslow's Theory is to attain the sixth level of stage: self - transcendent needs. Maslow's hierarchy of needs is often portrayed in the shape of a pyramid with the largest, most fundamental needs at the bottom and the need for self - actualization and self - transcendence a t the top. The most fundamental and basic four layers of the pyramid contain what Maslow called \"deficiency needs\" or \"d - needs\": esteem, friendship and love, security, and physical needs. If these \"deficiency needs\" are not met – with the exception of th e most fundamental (physiological) need – there may not be a physical indication, but the individual will feel anxious and tense. Maslow's theory suggests that the most basic level of needs must be met before the individual will strongly desire (or focus m otivation upon) the secondary or higher level needs. The human brain is a complex system and has parallel processes running at the same time, thus many different motivations from various levels of Maslow's hierarchy can occur at the same time. Maslow spoke clearly about these levels and their satisfaction in terms such as \"relative\", \"general\", and \"primarily\". Instead of stating that the individual focuses on a certain need at any given time, Maslow stated that a certain need \"dominates\" the human org anism. Thus Maslow acknowledged the likelihood that the different levels of motivation could occur at any time in the human mind, but he focused on identifying the basic types of motivation and the order in which they should be met."
