Any spatial situation can be approached either categorically - the window is to my left - or coordinately - the glass is 20cm away from the bottle. Since the first description of the distinction between categorical and coordinate spatial relation processing, it has often been shown that they are processed by at least partially different underlying mechanisms, mainly located in the left and right hemisphere, respectively. A number of recent studies have suggested that spatial attention plays a particularly important part in the perception of space: categorical processing benefits from a local focus of attention, and coordinate processing profits from a global focus of attention. This suggests that the lateralization pattern is modified by the concurrent size of the attentional focus, and is consequently more dynamic than previously thought. Therefore, a thorough revision of earlier theories on spatial relation processing is in order. In this review, we present a new model on lateralization of spatial relation processing that explicitly describes the role of spatial attention.
任何空间情境都可以通过分类方式来描述——窗户在我的左边——或者通过坐标方式来描述——玻璃杯距离瓶子20厘米。自从首次描述分类和坐标空间关系处理之间的区别以来，人们经常发现它们是由至少部分不同的潜在机制处理的，这些机制主要分别位于左半球和右半球。最近的一些研究表明，空间注意力在空间感知中起着特别重要的作用：分类处理受益于局部注意力焦点，而坐标处理则受益于全局注意力焦点。这表明，偏侧化模式会受到注意力焦点同时大小的影响，因此比之前认为的更具动态性。因此，有必要对早期关于空间关系处理的理论进行全面修订。在这篇综述中，我们提出了一个关于空间关系处理偏侧化的新模型，该模型明确描述了空间注意力的作用。
