Attention is multifaceted, with evidence for distinct mechanisms of attentional facilitation and suppression processes. Interestingly, much less is known about the spatial coordinate system of suppression compared to that of facilitation. The present study examined the coordinate system of spatial suppression by manipulating gaze position and distractor regularities, asking whether suppression is coded in retinotopic (eye-centered) and/or spatiotopic (world-centered) coordinates, and if this varies with more ecological and dynamic contexts. In the current study, we demonstrate that learned spatial suppression primarily transfers across gaze position in retinotopic coordinates; however, in more dynamic contexts favoring spatiotopic information, spatial suppression can be learned in spatiotopic coordinates. These results suggest that the default coordinate system of spatial suppression is retinotopic under static contexts, but suppression can be rapidly learned in spatiotopic coordinates when a spatiotopic representation is beneficial in more naturalistic dynamic contexts.
注意力是多方面的，有证据表明存在注意力促进和抑制过程的不同机制。有趣的是，与促进过程相比，人们对抑制的空间坐标系了解得要少得多。本研究通过操纵注视位置和干扰物规律来检验空间抑制的坐标系，探讨抑制是在视网膜坐标系（以眼睛为中心）和/或空间坐标系（以世界为中心）中编码的，以及这是否会随更具生态性和动态性的情境而变化。在当前研究中，我们证明，习得的空间抑制主要在视网膜坐标系中跨注视位置转移；然而，在更有利于空间坐标信息的动态情境中，空间抑制可以在空间坐标系中习得。这些结果表明，在静态情境下，空间抑制默认的坐标系是视网膜坐标系，但当空间坐标表征在更自然的动态情境中有益时，抑制可以在空间坐标系中快速习得。
