获得性右大脑半球损伤患者的持续注意力和空间注意力缺陷的共存导致了持续注意力可能是左空间注意力不集中或忽视的标志。我们研究了这种可能性，即空间注意力不对称的减少可能源于个体持续注意力能力的差异，即使是在健康的成年人群体中。我们观察到，在持续注意力测试中表现不佳的健康受试者在自由观看空间注意力测试中，相对于具有良好持续注意力能力的受试者，左空间偏差显著减弱。我们的研究结果提供了进一步的支持的概念，持续的注意可能会产生调节作用的空间注意。
The co-existence of deficits in sustained and spatial attention in patients with acquired damage to the right cerebral hemisphere has led to the proposition that sustained attention could be a marker for left spatial inattention, or neglect. We investigated the possibility that reductions in leftward spatial attentional asymmetries could arise from individual differences in the capacity for sustained attention even within healthy adult populations. We observed that healthy participants who performed poorly on a test of sustained attention had a significantly attenuated left spatial bias, relative to those with good sustained attention capacity, on a free-viewing spatial attention test. Our results provide further support for the notion that sustained attention may exert a modulatory influence on spatial attention.
