Abstract:
The recent advancements in virtual reality technology and generative AI have made it possible to create environments, images, and texts that are indistinguishable from the real things. These technological developments serve as a catalyst for rethinking the nature of atypical states of mind, such as hallucinations, delusions, and depersonalization, as disorders of ‘sense of reality’. This talk will categorize the sense of reality into three groups: ‘perceptual reality’, ‘subjective veridicality’, and ‘doxastic veridicality’, and will examine how each is involved with respective symptoms. Furthermore, I will present my own research findings using cognitive psychological experiments, combined with the virtual reality technologies and deep learning models, all aimed at understanding the cognitive and computational mechanisms of the sense of reality.
