参与自我反思过程的能力是一种在神经系统受损后可能会被破坏的能力;迄今为止的研究表明，与看护人或临床医生报告相比，创伤性脑损伤（TBI）患者对其缺陷和功能能力的认识降低。然而，对缺陷意识的评估受到主观衡量标准（不与实际业绩进行比较）的限制，这些主观衡量标准容易受到报告偏见的影响。本研究使用认知测试和对表现的信心判断的同时测量来调查中度和重度创伤性脑损伤后的即时元认知体验。在TBI的成年人中发现了一些但不是所有指标的元认知准确性缺陷，这表明元认知可能不是一个单一的结构。研究结果还显示，并非所有的指标执行功能可靠地预测元认知能力。(JINS，2011，17，720-731）
The ability to engage in self-reflective processes is a capacity that may be disrupted after neurological compromise; research to date has demonstrated that patients with traumatic brain injury (TBI) show reduced awareness of their deficits and functional ability compared to caretaker or clinician reports. Assessment of awareness of deficit, however, has been limited by the use of subjective measures (without comparison to actual performance) that are susceptible to report bias. This study used concurrent measurements from cognitive testing and confidence judgments about performance to investigate in-the-moment metacognitive experiences after moderate and severe traumatic brain injury. Deficits in metacognitive accuracy were found in adults with TBI for some but not all indices, suggesting that metacognition may not be a unitary construct. Findings also revealed that not all indices of executive functioning reliably predict metacognitive ability. (JINS, 2011, 17, 720-731)
