The ability to accurately estimate the passage of time plays an important role in helping to structure daily activities. In this study, we used a prospective verbal time estimation paradigm to investigate time perception in 27 moderate to severe traumatic brain injury (TBI) participants and 27 controls. Verbal time estimations were made for filled intervals both within (i.e., <30 s) and beyond the time frame of working memory. We found that the TBI participants exhibited normal or near-normal estimates of time passage for duration up to 25 s. In contrast, for durations that exceeded working memory, the TBI group perceived less time as having passed than actually had passed as the TBI group significantly underestimated time when compared to controls. This pattern of data was interpreted as being due to episodic memory dysfunction.
准确估计时间的流逝能力在安排日常活动中起着重要作用。在本研究中，我们采用前瞻性言语时间估计范式，对27名中度至重度创伤性脑损伤（TBI）参与者和27名对照组进行时间感知调查。对工作记忆时间范围内（即<30秒）和超出该范围的填充时间间隔进行言语时间估计。我们发现，TBI参与者在长达25秒的持续时间内对时间流逝的估计正常或接近正常。相比之下，对于超过工作记忆的持续时间，TBI组感知到的过去时间比实际过去的时间少，因为与对照组相比，TBI组显著低估了时间。这种数据模式被解释为是由于情景记忆功能障碍所致。
