In reviewing the huge effort made by the psychological research in defin- ing the main components of the creative process and of the creative potential, rarely we encounter models and theoretical frameworks considering emotional reactions as main determinants of the creative process, except of the widely and broadly defined concepts of motivation and mood. Emotional phenomena are usually intended as strong (intrinsic or extrinsic) forces able to influence the creative think- ing process, and in particular the cognitive processes sustaining idea generation. In this chapter, we maintain that emotional phenomena are not simple influencers of creative thinking, but that they are the spinal cord of the creative process. In consid- ering emotions the core of the process, we sustain that emotional reactions are the conditio sine qua non by which the creative thinking process can occur, or, in differ- ent words, the necessary (although not sufficient) determinant of the process. On the basis of the above, taking into account different theoretical approaches to the study of emotions and adopting a dynamical systems framework, we intend to explain the role of emotions in the dynamic emergence of the creative thinking process.
