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.

精神分裂症患者保持集中注意力的能力受损。我们探讨如何在“下一个国家”的预测问题有助于注意力的问题。大脑不断地预测它下一次将处于什么样的激活状态。当事件符合这些预测时，我们可以很容易地忽略它们，但如果预测是错误的，预测错误可能会引发注意力中断。我们将测试预测错误的问题是否使精神分裂症患者更容易分心。
