Abstract:

Over the course of my PhD I have investigated issues related to two main areas of investigation in cognitive science, namely Schizophrenia and Metacognition. My dissertation is divided in two parts: the first part includes three experimental studies (two studies in healthy subjects and one study in people with schizophrenia) and two theoretical studies addressing specific aspects of schizophrenia; the second part includes four theoretical studies addressing the role of metacognition in specific debates in philosophy and cognitive science of perception.

            I have explored two symptomatic expressions of schizophrenia, thought insertion and experiences of activity, as well as a potential cognitive bias, namely the potential presence of perceptual persistence biases. With respect to metacognition, I have investigated ways in which consideration of the role of metacognitive feelings (the experiential output of metacognitive processes) could shed new light on important current debates in analytical philosophy and cognitive science. The issues I have focused on are: the problem of hallucinations, the debate about cognitive penetrability (i.e., whether or not higher-order cognitive states may influence perceptual processes), the perception of absences and sensory substitution.
