The relation between duration of post-traumatic amnesia (PTA), performance on memory tests, and the Paced Auditory Serial Addition Task (PASAT) was examined in two samples of young adult closed head injury patients. Three different effects were isolated: (1) an attention and concentration factor, related to PASAT scores, (2) a deficit in the ability to place material into long-term memory storage, related to PTA durations, and (3) an impairment in the ability to retrieve material once it has been stored, which was not predicted by either PTA or PASAT.
在两组年轻成人闭合性颅脑损伤患者样本中,研究了创伤后遗忘症(PTA)持续时间、记忆测试表现与听觉序列加法任务(PASAT)之间的关系。分离出三种不同的效应:(1)与PASAT分数相关的注意力和专注力因素;(2)与PTA持续时间相关的将材料存入长期记忆库的能力缺陷;(3)材料存储后提取能力的损伤,这一损伤无法通过PTA或PASAT预测。
