目的探讨闭合性脑外伤患者恢复期的图画遗忘特征。方法2012 年10 月~2013 年8 月，采用视觉彩色有意义图片，目标图片和干扰图片各60 张，对38 例闭合性脑外伤恢复期患者及31 名正常人进行再认测验，观察学习后10 min、30 min及24 h 的辨别力(d′)。结果14 例闭合性脑外伤恢复期患者10 min时d′<2，未行长时记忆研究。另24 例患者d′学习后30 min和24 h 与正常组相比有显著性差异(t>2.044, P<0.05)；患者组内比较，d′学习后10 min、30 min 与24 h 均有显著性差异(P<0.05)。结论闭合性脑外伤恢复期患者图画遗忘部分表现为图画信息获得受损；图画信息获得能力相对正常的患者，遗忘速度明显加快。

Objective To investigate the characteristic of picture forgetting in closed traumatic brain injury (CTBI) patients during recovery. Methods From October, 2012 to August, 2013, 60 colour slides of target or interference picture were presented to 38 CTBI patients during recovery and 31 matched healthy controls. Their discriminability index (d′) was observed 10 minutes, 30 minutes and 24 hours later. Results Forteen patients failed to attain d′ of 2.0 10 minutes later, and were excluded from further study. The d′ of the other 24 patients was less than that of the controls 10 minutes, 30 minutes and 24 hours later (t>2.044, P<0.05). The d′ in the patients was more of 10 minutes and 30 minutes than that of 24 hours (P<0.05). Conclusion Some patients with CTBI during recovery exhibit impairment in acquisition of pictorial information, and accelerated forgetting is found in the others without impairment.
