Introduction In the 1960’s psychodynamic inference was not capable of keeping its overall recognition. Psychotherapy began to bring on an issue of concern with limitations of the inference, particularly analyzing humanistic manner to do things. Maslow and Rodgers developed a special manner to handle the argument inside the psychodynamic inference (Bandura, 1997). Analyzing the data of researching, humanistic, and existential individuality premises shows a huge demonstration of the human character and behavior or characteristics since it develops by reaction to the external environment. This paper discusses the two premises of individuality and how this had effect on individual behaviors. How humanistic and existential premises influence personal behaviors The humanistic premise refers to the psychosomatic awareness of good in every individual.

Maslow believed genetic aspects offered the fundamental metric for the person; however, ecological and ethnic influences shaped the self-esteem or character (Feist & Feist, 2009). Rogers identified self-knowledge in people, and such knowledge allowed them to make decisions and proactively contribute to the development of their own individualities (Bandura, 1997).
