作为一个人的行为的来源和控制者的感觉，以及他们在外部世界的影响，是我们自我意识的一个重要方面。在精神分裂症患者中观察到这种代理感（SoA）的干扰，并已与感觉运动整合的损伤有关。我们使用虚拟世界动作监测范式调查了20名精神分裂症患者和18名健康受试者的SoA。参与者使用触摸板设备连续移动显示在计算机屏幕上的虚拟笔。他们对虚拟笔的控制权在参与者和计算机之间定期切换。参与者被要求监测他们的行动和对虚拟笔的影响，并表明失去或恢复控制笔的运动按钮pressing.The错误的外部归因的行动效果（假阴性机构判断）和错误的自我归因（假阳性机构判断）的数量在患者和健康受试者之间没有显着差异。然而，患者表现出显着增加的持续时间ofalse负面机构的判断。此外，只有在精神分裂症患者组中，虚假的消极能动判断的数量以及虚假的积极能动判断的数量和持续时间与认知测试（BACS）中的表现呈负相关。我们的研究结果表明，精神分裂症患者检测行为与其在外部世界中的效果之间不匹配的评估系统可能更加严格，这会导致对行动效果的自我归因偏差增加，这在控制妄想中很常见。感觉运动整合的损伤可以通过更强的认知控制来补偿。
The feeling of being the source and controller of one's actions and their effects in the outside world is an important aspect of our sense of self. Disturbances in this sense of agency (SoA) were observed in schizophrenia and have been linked to impairments in sensorimotor integration.We used a virtual-world action-monitoring paradigm to investigate the SoA in 20 schizophrenic patients and 18 healthy subjects. Participants continuously moved a virtual pen displayed on a computer screen using a touchpad device. The control they exceeded over the virtual pen was switched periodically between the participant and the computer. Participants were requested to monitor their actions and the effects on the virtual pen, and indicate loss or regain of control over the pen's movement by button presses.The numbers of erroneous external attribution of action effects (false negative agency judgements) and erroneous self-attribution (false positive agency judgements) were not significantly different in patients and healthy subjects. However, patients showed a significant increase in the duration offalse negative agency judgements. Moreover, the number offalse negative agency judgementsas well as the number and the duration offalse positive agency judgementswere negatively correlated with the performance in cognitive tests (BACS) in the patient group only.Our findings indicate that the evaluation system to detect a mismatch between actions and their effects in the outside world is probably more rigid in schizophrenic patients, which leads to an increased self-attribution bias for action effects, as commonly found in delusions of control. The impairment in sensorimotor integration may be compensated for by stronger cognitive control.
