The document discusses 4 key psychological processes that influence consumer response: theories of motivation, perception, learning, and attitude. It outlines 3 major theories of motivation by Freud, Maslow, and Herzberg, and notes that Freud's theory emphasizes the importance of the unconscious mind in governing behavior to a greater degree than people suspect. The goal of psychoanalysis is to make the unconscious conscious, as depicted by the iceberg analogy. The document was created by Sameer Agarwal during an internship with Professor Sameer Mathur to discuss psychological factors that impact consumer behavior.
