Violation of expectation: Neural correlates reflect bases of prediction

Setting perceptual expectations can be based on different sources of information which determine the functional networks involved in implementing preparatory top-down influences and dealing with situations in which expectations are violated. The present study addressed the process of forming and violating expectations based on information of different origin, type and specificity. In the serial prediction task participants monitored ordered perceptual sequences for predefined sequential deviants, while the target detection task entailed a presentation of stimuli which had to be monitored for predefined non-seque…
