A major development in recent research on human visual attention has been the increasing interplay between research on normal attentional mechanisms, and accounts of unilateral neglect and extinction after brain-damage in terms of damage to these mechanisms. Although there are potential pitfalls in this approach, it has already proved useful. This is illustrated for the debate over whether segmentation processes precede spatial attention in vision. This debate began in the normal literature, but has since motivated several studies of visual neglect and extinction. These reveal that various segmentation processes can influence which region of a scene will be neglected or extinguished, implying that grouping may precede the abnormal bias in spatial attention, and showing that considerable residual processing can take place in the neglected or extinguished visual field. The extent of this residual processing is tentatively related to emerging anatomical data.
人类视觉注意力的近期研究中的一个主要进展是，关于正常注意力机制的研究与对脑损伤后单侧忽视和消退现象（根据这些机制的损伤情况）的描述之间的相互作用日益增加。尽管这种方法存在潜在的缺陷，但已被证明是有用的。这在关于视觉中分割过程是否先于空间注意力的争论中得到了体现。这场争论始于正常研究文献，但此后引发了多项关于视觉忽视和消退的研究。这些研究表明，各种分割过程会影响场景中的哪个区域会被忽视或消退，这意味着分组可能先于空间注意力中的异常偏向，并表明在被忽视或消退的视野中可以进行相当程度的残余加工。这种残余加工的程度初步与新出现的解剖学数据相关。
