- Abstract
- The work aims at investigating unconscious processing in the human brain. It is composed by an introduction (chapter I), the experimental section composed by four studies (chapters II to V) and the discussion/conclusion. The introduction consists of two parts: the first one provides an overview of unconscious processes from a critical perspectives, whereas the second part presents an overview about physiological mechanisms driving the pupillary response and its relationship with unconscious cognitive mechanisms. The main core of the thesis is the experimental part, composed of 4 studies. The first study introduces a novel framework to reliably study unconscious processing, addressing the main criticisms discussed in the first part of the introduction. The second and third study exploit this novel framework to investigate the relationship between unconscious learning and overt visual attention. Finally, the last study reveals how pupillary responses can be used to track statistical implicit learning, suggesting that pupil dilates at the occurrence of unconscious surprising events. The conclusion of the thesis contextualizes the finding in the literature and discusses the main limitations.
