psychic determinism views behaviour as determined by psychological processes
the psychodynamic approach, for psychic determinism, regards all thoughts and behaviour as originating from the unconscious mind
unconscious factors such as life and death instincts, childhood experiences and disturbing memories can all influence behaviour
for FREUD there are no accidents, no matter how apparently random or irrational the behaviour may appear to be, unconscious causes always account for them
people believe they're free, but in FREUD's view, this is an illusion
