title: Sustained attention and information processing speed in chronic survivors of severe closed head injury.
abstract: 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.
