1. Personality Theorists - Psychoanalytical and Humanistic

Humanistic - Maslow and needs

This approach to personality and behavior  started to gain footing in the 1960‘s.  This approach is different from the psychoanalytical  theories, in that it suggests humans have free will.  People are able to make decisions that contribute to one's personality.

Abraham Harold Maslow was born April 1, 1908 in Brooklyn, New York.  His parents were uneducated Jewish immigrants from Russia. He first studied law at the City College of New York before moving to Wisconsin to attend the University of Wisconsin.  There, he became interested in psychology, and received his undergraduate degrees and  PhD (1934).  

While doing research with monkeys with Harry Harlow, Maslow noticed that some needs take precedence over other needs.  This idea led to his theory of the hierarchy of needs.
