Abstract：
The visual system adapts to a wide range of visual features, from lower-level features like color and motion to higher-level features like causality and, perhaps, number. According to some, adaptation is a strictly perceptual phenomenon, such that the presence of adaptation licenses the claim that a feature is truly perceptual in nature. Given the theoretical importance of claims about adaptation, then, it is important to understand exactly when the visual system does and does not exhibit adaptation. Here, we take as a case study one specific kind of adaptation: visual adaptation to size. Supported by evidence from four experiments, we argue that, despite robust effects of size adaptation in the lab, (1) size adaptation effects are phenomenologically underwhelming (in some cases, hardly appreciable at all), (2) some effects of size adaptation appear contradictory, and difficult to explain given current theories of size adaptation, and (3) prior studies on size adaptation may have failed to isolate size as the adapted dimension. Ultimately, we argue that while there is evidence to license the claim that size adaptation is genuine, size adaptation is a puzzling and poorly understood phenomenon.
摘要：
视觉系统适应广泛的视觉特征，从颜色和运动等低级特征到因果关系等高级特征，也许,number.根据一些,适应是一种严格的感知现象，这样，适应的存在许可的声称，一个特征是真正的感知性质。鉴于索赔关于适应的理论重要性，然后,重要的是要确切地了解视觉系统何时表现出适应性和不表现出适应性。这里,我们将一种特定的适应作为案例研究：对尺寸的视觉适应。有四个实验的证据支持，我们认为，尽管实验室中的尺寸适应具有强大的效果，(1)尺寸适应效应在现象学上表现不佳(在某些情况下，几乎无法察觉)，(2)尺寸适应的一些效果出现矛盾，鉴于目前的大小适应理论，很难解释，(3)先前关于尺寸适应的研究可能未能将尺寸分离为适应尺寸。最终,我们认为，虽然有证据表明尺寸适应是真实的，尺寸适应是一个令人困惑和知之甚少的现象。
