研究表明，在之前遭受过轻微头部损伤(MHI)的其他功能良好的人中，存在着微妙的长期认知变化。本研究探讨了MHI对正常大学生视觉记忆、空间记忆和视觉空间短时记忆的长期影响。对16名报告遭受过MHI的学生和16名对照组进行了短期记忆(STM)测试，测试对象是随机排列位置的抽象多边形。这三种测试的不同之处仅在于回忆的要求(视觉任务的形状、空间任务的位置以及视觉空间任务各自位置的形状)。MHI参与者的空间记忆受到选择性损害，这表明与视觉STM任务相比，空间STM任务可能对MHI后可能出现的微妙的长期认知变化更敏感。(C)2004 Elsevier Inc.保留所有权利。
Research has suggested the presence of subtle long-term cognitive changes in otherwise well-functioning individuals who have previously sustained a mild head injury (MHI). This paper investigated the long-term effects of MHI on visual, spatial, and visual-spatial short-term memory in well-functioning university students. Sixteen students who reported having sustained a MHI were compared to 16 controls on tests of short-term memory (STM) for abstract polygons in haphazardly arranged locations. The three tests differed only in the requirements for recall (shapes for the visual task, locations for the spatial task, and the shapes in their respective locations for the visual-spatial task). MHI participants were selectively impaired on spatial memory, suggesting that tasks of spatial STM may be more sensitive, compared to tasks of visual STM, to the subtle long-term cognitive changes that may be present after a MHI.
