The role of spatial scales (or spatial frequencies) in the processing of faces, objects, and scenes has recently seen a surge of research activity. In this review, we will critically examine two main theories of scale usage. The fixed theory proposes that spatial scales are used in a fixed, perceptually determined order (coarse to fine). The flexible theory suggests instead that usage of spatial scales is flexible, depending on the requirements of visual information for the categorization task at hand. The implications of the theories are examined for face, object, and scene categorization, attention, perception, and representation.
空间尺度（或空间频率）在面部、物体及场景处理中的作用，近来引发了大量研究活动。在本综述中，我们将批判性地审视两种关于尺度运用的主要理论。固定理论提出，空间尺度按照固定的、由感知决定的顺序（从粗略到精细）被运用。相反，灵活理论则认为，空间尺度的运用是灵活的，这取决于手头分类任务对视觉信息的需求。我们将探讨这些理论对面部、物体及场景分类、注意力、感知和表征的影响。
