"In a curious way, trait theory has been ignored by personality theorists who emphasize either conscious influences on behaviour, or unconscious influences.... Such theorists as A.Bandura (1986, Social Foundations of Thought and Action) and G.A.Kelly (1955, The Psychology of Personal Constructs) would agree, for somewhat different reasons, that one cannot understand personality without understanding the thoughts and beliefs of an individual.... Psychodynamic theorists and Freudians would find trait theorists' emphasis on behavioural acts a superficial analysis of personality. They would insist that the true reasons for human actions are to be found in unconscious influences...."
