准确估计时间流逝的能力在帮助组织日常活动方面起着重要作用。在这项研究中，我们使用了一个前瞻性的口头时间估计范式调查的时间知觉在27个中度至重度创伤性脑损伤（TBI）的参与者和27个控制。对填充间隔进行口头时间估计（即，<30 s）和超出工作记忆的时间框架。我们发现，TBI参与者表现出正常或接近正常的估计持续时间长达25秒。相比之下，对于超过工作记忆的持续时间，TBI组感知的时间比实际通过的时间要少，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。
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.
