Intended for personality courses, this text integrates traditional personality theories with current research by personality psychologists. Each theory chapter is followed by a relevant research chapter where the author covers three or four topics of current personality research in some detail. Each of seven major personality theories/approaches, Freudian, non-Freudian, trait, biological, humanistic, behavioural/social learning, and cognitive, is covered using this effective two-chapter pairing of theory and research. To give students a view of the research process, Burger focuses on research programmes, illustrating how the questions being investigated are connected to a larger theory, how researchers develop their initial investigations, and how their experimental findings lead to better refined hypotheses and modification of theories.
