Patient NC showed impairment on several tasks making use of coordinate spatial information, while categorical processing was at control level. Her assessment of local and global features of visual stimuli indicated that she had a local bias of attention, whereas controls showed a global bias. Her problems with coordinate tasks can be explained by this reduced global attentional focus. These findings confirm previous reports suggesting that the processing of categorical spatial relations benefits from a small scope of attention, whereas a relatively large scope of attention enhances coordinate spatial relation processing.
患者NC在利用坐标空间信息的多项任务上表现出损伤，而类别处理处于正常水平。她对视觉刺激的局部和全局特征的评估表明，她存在注意力的局部偏向，而对照组则表现出全局偏向。她在坐标任务上的问题可以通过这种全局注意力焦点的降低来解释。这些发现证实了先前的报告，表明类别空间关系的处理受益于较小的注意力范围，而相对较大的注意力范围则增强了坐标空间关系的处理。
