The performance of a group of 60 severely closed-head-injured patients in the subacute stage of recovery on a series of tests addressing focused, divided, and sustained attention, and supervisory attentional control was compared to the performance of a matched group of 60 healthy controls. Patients performed significantly worse on each test with time pressure (those addressing focused and divided attention), indicating basic slowness of information processing, and on the self-paced tasks for supervisory attentional control. No indication was found of a sustained attention deficit. In a subsequent analysis the influence of the demonstrated slowness of information processing and other possibly confounding cognitive factors was controlled for by means of covariance analyses. This resulted in a disappearance of group differences on tests for focused and divided attention. The only difference that remained concerned a test for supervisory attentional control.
将一组60名处于亚急性期恢复阶段的严重闭合性颅脑损伤患者在一系列针对集中注意力、分散注意力、持续注意力和监督性注意力控制的测试中的表现，与一组匹配的60名健康对照者的表现进行了比较。在有时间压力的测试（即针对集中注意力和分散注意力的测试）中，患者在每项测试中的表现明显更差，这表明信息处理存在基本的迟缓，在监督性注意力控制的自定节奏任务中也是如此。未发现持续注意力缺陷的迹象。在随后的分析中，通过协方差分析控制了已证明的信息处理迟缓及其他可能混淆的认知因素的影响。这导致在集中注意力和分散注意力测试中，组间差异消失。唯一仍然存在的差异涉及一项监督性注意力控制测试。
