这项研究调查了严重闭合性头部损伤 (CHI) 人群工作记忆的执行方面。 34 名重度 CHI 参与者（伤后 >1 年）和 34 名对照者完成了 Petrides 和 Milner（1982）的自定指向任务的设计版本。 CHI 参与者在 16 项试验中比对照组犯了更多错误，但在 9 项试验中则不然。 CHI 和对照参与者都能够利用策略处理来提高 SOPT 性能。正如预期的那样，SOPT 的错误与对照组的另一种工作记忆测量（即阅读广度测试）相关。相比之下，对于 CHI 参与者来说，SOPT 的错误与延迟视觉记忆的测量有关（即韦克斯勒记忆量表 - 修订的视觉再现 II 子测试）。我们的研究结果表明，作为一个群体，导致 CHI 组 SOPT 表现较差的主要因素是记忆缺陷，而不是利用工作记忆的执行方面的能力。
This study investigated executive aspects of working memory in a severe closed-head injured (CHI) population. Thirty-four severe CHI participants (>1 year postinjury) and 34 controls completed an design version of Petrides and Milner’s (1982) self-ordered pointing task. CHI participants made more errors than controls on the 16-item trial, but not the 9-item trial. Both CHI and control participants were able to make use of strategic processing to improve SOPT performance. As anticipated, errors on the SOPT were associated with another measure of working memory (i.e., Reading Span Test) for the control group. In contrast, for the CHI participants, errors on the SOPT were associated with a measure of delayed visual memory (i.e., Wechsler Memory Scale – Revised Visual Reproduction II subtest). Our findings suggest that, as a group, the primary factor resulting in poorer SOPT performance by the CHI group was a memory deficit and not the ability to utilize executive aspects of working memory.
