Patients suffering from unilateral left visual neglect may show problems in deploying attention generally in space, particularly in "controlled processing" type tasks (Schneider and Shiffrin), in addition to showing specifically lateralized attentional difficulties. The prediction is made that cueing to the left should result in a significant increase in right-sided omissions because of this general attentional difficulty. This hypothesis was confirmed, and two patterns of results were observed. One group continued to neglect a left stimulus in the cued condition, in spite of accurately reading a word on the left side, while the other group showed a mainly right-sided omission pattern.
患有左侧单侧视觉忽视的患者，除了表现出特定的单侧注意力困难外，在空间中总体上部署注意力时可能会出现问题，尤其是在“控制性加工”类型的任务中（施奈德和希夫林）。基于这种普遍的注意力困难，预计向左提示会导致右侧遗漏显著增加。这一假设得到了证实，并且观察到了两种结果模式。一组在提示条件下继续忽视左侧刺激，尽管能准确读出左侧的一个单词，而另一组则表现出主要为右侧遗漏的模式。
