Psychodynamic approach to personality emphases that the unconscious forces determine our personality
Psychodynamic theory is strongly determinist as it views our behaviour as caused entirely by unconscious factors over which we have no control.
Unconscious thoughts and feelings can transfer to the conscious mind in the form of parapraxes, popularly known as Freudian slips or slips of the tongue. We reveal what is really on our mind by saying something we didn’t mean to.
Freud believed that slips of the tongue provided an insight into the unconscious mind and that there were no accidents, every behaviour (including slips of the tongue) was significant (i.e., all behaviour is determined).
