我们评论了Farah等人的一篇论文，其中声称一组左单侧空间忽视（USN）患者在字母命名任务上的平均表现提供了证据，表明空间注意力分配是由以环境为中心和以观众为中心的坐标定义的，而不是由以物体为中心的坐标定义的。我们重新分析了该论文的原始数据，并对来自个体受试者的数据进行了统计分析，这些数据显示了USN个体受试者使用的坐标框架中的分离。来自个别案例的数据表明，在某些情况下，以对象为中心的USN单独发生（在其他参照系中没有USN的证据），在其他参照系中与USN相关联。与从群体表现中得出的结论相反，个体受试者的结果为可分离的参考框架（包括以物体为中心的坐标框架）在注意力的空间分配中的作用提供了证据。
We comment on a paper by Farah et al. [12]in which it is claimed that averaged performance on a letter naming task by a group of patients with left unilateral spatial neglect (USN) provides evidence that spatial allocation of attention is defined by environment-centered and viewer-centred coordinates, but not by object-centred coordinates. We re-analyze the raw data from that paper, and present statistical analyses of the data from individual subjects which show dissociations in the coordinate frames used by the individual subjects with USN. The data from individual cases demonstrate that object-centered USN occurs alone (without evidence of USN in other reference frames) in some cases, and in association with USN in other reference frames other cases. In contrast to the conclusions drawn from the group performance, results from individual subjects provide evidence for the role of dissociable frames of reference, including an object-centred coordinate frame, in the spatial allocation of attention.
