The current study aimed to address error monitoring impairments in dementia using an intervention for execution deficits. Thirty-eight participants completed the Naturalistic Action Test (NAT) under two conditions: Standard and User-Centered. The Standard NAT followed the manual procedures; in the User-Centered NAT, objects were arranged sequentially, and distractor items were separated from target objects. While participants committed fewer errors in the User-Centered condition, there was no difference in the proportion of errors detected. However, the neuropsychological processes associated with monitoring differed across conditions. The results have implications for a neuropsychological model of error monitoring in dementia.
本研究旨在通过针对执行缺陷的干预来解决痴呆症中的错误监控损伤。38 名参与者在两种条件下完成了自然动作测试（NAT）：标准条件和以用户为中心的条件。标准 NAT 遵循手册程序；在以用户为中心的 NAT 中，物体按顺序排列，干扰项与目标物体分开。虽然参与者在以用户为中心的条件下犯的错误较少，但检测到的错误比例没有差异。然而，与监控相关的神经心理学过程在不同条件下有所不同。研究结果对痴呆症错误监控的神经心理学模型具有启示意义。
