The course embarks on comprehensive analyses of the major theories of personality. It starts with a study of different dimensions of the psychoanalytic theories and motives such as neopsychoanalytic approach (analytical psychology, inter-psychic theories and psychoanalytic social psychology.) more recent trends (ego analytic psychology and human relations) are also treated. The course goes further to the study of behaviour and learning theories (experimental analysis of behaviour and social psychology theories); dispositional theories (trait theories and temperament; factor analytic theories , theories, biological traits); self-theory and cognition (personal construct, cognitive behavioural theories); humanistic/existential theories (humanism and existential psychologises) and social context-situation ( social structure and culture). The implications to their therapeutic practices as well as their educational implications will be examined.
