This is a masterful examination of three contemporary scientific approaches to the study of personality--the psychodynamic, the trait-psychobiological, and the cognitive. The book also focuses on corresponding theoretical frameworks that continue to guide much of the research on personality disorders--Attachment and Separation, the psychobiological paradigm, and cognitive frameworks. Personality Science engages the reader in a discussion of applied personality theories on psychopathology and the crucial contemporary research they have generated: prospective studies from childhood to adulthood, and concurrent studies of the biological correlates of major personality traits.
