OBJECTIVE
To document the process by which metacognitive judgments ("online" monitoring of one's own cognitive performance during task completion) are made after traumatic brain injury (TBI).
PARTICIPANTS
Sixteen community-dwelling adults with moderate to severe TBI and 16 matched healthy controls.
DESIGN
Prospective, cross-sectional design.
MEASURES
Metacognitive retrospective confidence judgments and reaction times were collected as participants performed a metamemory task.
RESULTS
Adults with TBI did not differ from healthy peers in metacognitive accuracy; however, they took significantly longer to make retrospective confidence judgments. Retrospective confidence judgment reaction times were not consistently correlated to measures of processing speed in either sample.
CONCLUSIONS
Adults with TBI engage in different postdecisional processes to make metacognitive judgments compared with healthy controls. Findings suggest that reaction times may be an important dimension of metacognition to assess clinically after TBI.
目的
记录创伤性脑损伤（TBI）后进行元认知判断（在完成任务过程中“在线”监测自己的认知表现）的过程。
参与者
16 名居住在社区的中重度 TBI 成年人和 16 名匹配的健康对照组。
设计
前瞻性、横断面设计。
测量
参与者完成元记忆任务时收集元认知回溯信心判断和反应时间。
结果
TBI 成年人与健康同龄人在元认知准确性上没有差异；然而，他们做出回溯信心判断的时间明显更长。在两个样本中，回溯信心判断反应时间都与处理速度的测量没有一致的相关性。
结论
与健康对照组相比，TBI 成年人在做出元认知判断时采用了不同的决策后过程。研究结果表明，反应时间可能是评估 TBI 后临床认知的一个重要维度。
