Sustained attention and information processing speed in 15 long-term survivors of severe closed head injury and 14 demographically matched controls have been examined. The average time between head injury and testing was 3.6 years. The performance of patients on all tasks was impaired relative to controls, thus documenting persistent deficits in attention. Of particular interest was the finding that controls were capable of redirecting and improving their sustained attention during a test session versus the steady decline in patient performance. The findings are discussed within the framework of controlled attentional processes.
对15名重度闭合性颅脑损伤长期幸存者和14名人口统计学匹配的对照组人员的持续注意力和信息处理速度进行了检测。头部受伤与测试之间的平均时间为3.6年。与对照组相比，患者在所有任务上的表现均受损，从而证明了注意力持续存在缺陷。特别值得关注的是，研究发现，与患者表现的持续下降相比，对照组在测试过程中能够重新定向并提高其持续注意力。本文在受控注意力过程的框架内对研究结果进行了讨论。
