One or more identities? Integrating personal and social identity

How are personal and social identity intertwined. This contribution represents an attempt to provide a preliminary answer to a fundamental question at the basis of the scientific activity of Augusto Palmonari. In order to achieve this aim, the key features of the processes underlying personal identity (commitment and various forms of exploration) and social identity (categorization, identification, social comparison, and group distinctiveness) are taken into consideration, discussing their interplay.
