In schizophrenia ability to maintaining focused attention is impaired. We explore how problems in “next state” prediction contribute to problems in attention. The brain constantly predicts what state of activation it will be in next. When events match these predictions we can easily ignore them but if predictions are wrong a prediction–error can trigger attention interruptions. We will test whether problems in prediction-errors make persons with schizophrenia more susceptible to distraction.
