Abstract
I use evidence from psychiatric disorders involving the experience of depersonalisation to decompose the causal and cognitive structure of experiences reported as self-awareness. I combine insights from predictive coding theory and the appraisal theory of emotion to explain the association between hypoactivity in the Anterior Insular Cortex and depersonalization. This resolves a puzzle for some theories raised by the fact that reduced affective response in depersonalization is associated with normal interoception and activity in Posterior Insular Cortex. It also elegantly accounts for the role of anxiety in depersonalisation via the role of attention in predictive coding theories.
