The idea of predictive coding, namely that perception is the combination of sensory feedback and prior predictions of sensory outcomes, has only recently been applied to interoception. However, in 2012, Seth, Suzuky & Critchley introduced a theoretical model which applied predictive coding to agency and interoceptive states. We are currently engaged in empirically testing the model assumptions to determine whether it provides an accurate account of the construction of internal awareness.
Sense of Agency
Sense of agency is the feeling of being in control of one's actions. It is a subtle feeling that we do not consciously think about very often. However, it might be hugely important for engaging with the world in a self-determined way. For example, in psychological disorders such as schizophrenia people are not always able to tell if their actions are self-controlled. We are investigating what factors might determine our sense of agency, and how it can be assessed objectively.
