Psychodynamics and Psychoanalysis
Psychodynamics and Psychoanalysis was conceptualized by Sigmund Freud in the later part of the Victorian Era (1856-1939). The theory and treatment model was the first clinically driven approach attempting to explain human behaviour following the work of Experimental Psychology. In short, the theory of Psychodynamics was foundational to the clinical application of Psychoanalysis.
Freud attempted to explain behaviour through the complicated interaction of conscious and subconscious forces. The primary components at play are the Id, Ego, and Superego. A well balanced individual should have a healthy ego that is able to meet the needs of the primitive Id, while managing the 'parental' messages of the Superego.
