Shame is a self-conscious emotion that characterizes the life of all individuals. It arises when a moral violation occurs and the person is judged negatively by others for a way of being that does not correspond to the standards of society. Although over the years it has been widely treated from a theoretical point of view, there are few attempts in the literature to approach it scientifically by psychologists and neuroscientists. Using an integrated approach, based on neuroimaging, behavioral and neuropsychological investigations, in this thesis we aimed to investigate what are the cognitive mechanisms through which shame operates and what are its neural bases. After an initial theoretical introduction in which a novel model of shame functioning is proposed, two behavioral studies are presented in which an innovative experimental paradigm of shame elicitation has been validated and tested. Subsequently, the single-case of a patient with rare bilateral amygdala damage has been described. Since this region is notoriously crucial for emotional aspects, we tested the possibility that an amygdala injury could also lead to deficits in perception and recognition of shame. Afterward, to investigate if shame had its own specific neural activation map, a meta-analysis on functional studies in the literature that investigated the neural bases of shame and guilt (another self-conscious emotion) has been carried out. Finally, given the heterogeneity of the paradigms included in the meta-analysis, we run an fMRI study using our novel paradigm in order to detect shame neural signal. In general, by combining different methodologies, this work allowed us to approach shame from different perspectives, from simple elicitation and behavioral measurement to its neural basis. This has added a piece of knowledge in the field of affective neuroscience regarding a moral emotion (i.e. shame) that is fundamental to individual well-being within our society.
