The document discusses two theories of motivation: Maslow's hierarchy of needs theory and McClelland's theory of need achievement. Maslow's theory proposes that people are motivated to fulfill basic physiological needs first, and then progress up a pyramid to fulfill safety, social, esteem, and self-actualization needs. McClelland identified three core motivators: need for achievement, affiliation, and power, with people having different characteristics depending on their dominant motivator. The document provides examples of how marketers appeal to different needs in their campaigns.
