ERP Repetition Effects and Mismatch Negativity Generation A Predictive Coding Perspective (2007, methodology): “The main attraction of this theory for the present review is that it makes specific predictions for the behavior of ERP components elicited in oddball tasks such as those commonly used to elicit MMN (Friston, 2005a).”
The Computational Anatomy of Psychosis (2013, background): “Specifically, it is suggested that the main problem in schizophrenia lies not with the prediction of sensory input per se, but in the delicate balance of precision ascribed to prior beliefs and sensory evidence (Friston, 2005; Corlett et al., 2011).”
A Bayesian account of ‘hysteria’ (2012, background): “The false percept would be a hallucination (Friston, 2005a).”
