One of the most profound developments in modern perception research has been the reformulation of perception as an inferential process. Instead of being a mere readout of sensory input, perception is now understood to be strongly determined by expectations that are generated based on prior knowledge5,10. This critical influence of expectations also applies to the perception of pain. Expectations have been shown to affect pain perception in an experimental context 3,8,15,33 and to predict pain treatment outcomes including long-term disability24 and psychological functioning7,9,11 in clinical populations.
