Ethical Approval

Ethical approval for the data collected in the present study was obtained from the University of Cambridge Psychology Research Ethics Committee. Participants gave informed consent prior to the start of the study. Participant data used in the current analysis was anonymised given that each participant was referred to by number rather than by name, and all other information included could not be used to identify the participant’s identity. In addition, participation in the study was voluntary as participants were able to leave the study at any time without penalty. Given the RM tasks that participants engaged in, no physical or psychological distress was caused by taking part in the study. The risk of potential boredom or fatigue that participants might have faced was addressed as through the experimenter giving participants breaks throughout the study.

Deciding what is real, what is not: Reality montioring and predictive coding in the brain

In this issue, Renmiu reports on a behavioural study into the relationship between deficits in reality monitoring (RM) and the propensity of individuals in a non-clinical population towards auditory verbal hallucinations (AVHs). This commentary introduces a complementary account of RM deficits from a cognitive computational perspective where RM is modelled as a hierarchy of Bayesian inference processes, similar to other types of decisions that we make in the face of uncertainty. Using these frameworks to interpret behavioural and neuroimaging data, neuroscientists and psychologists hope to understand the emergence, progression, and persistence of sensory hallucinations.
