Personality psychology and psychopathology are the main areas of the interest of the Unit. Personality may be described as a complex system involving emotional, cognitive and behavioral components which develops across the life cycle in a complex network of person-environment transactions. Personality may explain both similarities and differences between different subjects, and it gives a sense of continuity in the experience of ourselves even when several of our aspects change. Personality andits role in the adaptive processes are the core research interests of our Unit. Latent structure analyses of adaptive and maladaptive personality, the role of the so-called adaptive traits in maladaptive behaviors, such as, aggressive behaviors, the study of impulsivity and aggression, and the development of evidence based techniques to treat personality disorders represent some contents of our research activities.
