Difference between deficiency needs and growth needs in Maslow's hierarchy.

The three lowest needs--physiological, security, and affiliation--are also known as deficiency needs. 

According to Maslow, unless these needs are satisfied, an individual will fail to develop into a healthy person, both physically and psychologically. 

In contrast, esteem and self-actualization needs are known as growth needs. Emergence of these needs as motivators will occur only after the deficiency needs have been largely satisfied. 

The satisfaction of growth needs helps a person to grow and develop as a human being. 

Thus, as long as nothing happens to block their emergence, the growth needs will come to motivate most people over time as they develop into healthy individuals.
