对30例重度颅脑损伤患者与15例对照组进行了听觉、声音、手指广度、自由回忆记忆任务的比较，考察了短期记忆（STM）和长期记忆（LTM）的功能。两组的自由回忆曲线不同，表明头部受伤患者的STM基本正常，但LTM较差。脑损伤患者的语义错误（可能是从LTM中检索到的）和正常的数字广度（STM）显著减少，这一发现支持了这一点。根据创伤后失忆或记忆测试时出现的神经学症状判断的损伤严重程度与记忆缺陷的严重程度只有微弱的关系。颅骨骨折的存在在确定LTM缺陷的严重程度方面是次要的。损伤后早期测试的患者在STM上明显较差，但在LTM上没有。
A group of 30 severely head injured patients was compared with 15 controls on auditory vocal digit span, and on a free recall memory task, enabling short term memory (STM) and long term memory (LTM) to be examined. The free recall curves differed for the two groups suggesting that the head injured patients had an essentially normal STM, but a poor LTM. This was supported by the finding of a significantly lower number of semantic errors (presumably retrieved from LTM) and a normal digit span (STM) in the head injury patients. The severity of the injury as judged by post-traumatic amnesia or the presence of neurological signs at the time of memory testing showed only a weak relationship to the severity of the memory deficit. The presence of a skull fracture was of minor importance in determining the severity of the LTM defect. Patients tested early after the injury were significantly poorer on STM, but not on LTM.
