Attentional Imbalances Following Head Injury

We have employed three tasks, developed by cognitive psychologists to study attention, with a population of six brain injured subjects in a rehabilitation program. Each of the tasks had been validated by studies with unilateral stroke patients and appear to provide a means of examining the relative...

Description
Summary:We have employed three tasks, developed by cognitive psychologists to study attention, with a population of six brain injured subjects in a rehabilitation program. Each of the tasks had been validated by studies with unilateral stroke patients and appear to provide a means of examining the relative efficiency of the two cerebral hemispheres when demands upon them are placed in conflict. We found that five of the six patients had imbalances between the two hemispheres. Four of them met our definition of attentional because the imbalance interacted with cues. The results show that the three tests converge on a common picture of cerebral imbalances in these brain injury patients and may relate to some aspects of their normal functioning.
