现实世界的物体可以在一定距离内观看,因此可以在视野范围内的可视角度范围内体验。考虑到观察对象时可能出现的大量视觉尺寸变化,我们研究了内部对象表示如何表示视觉尺寸信息。在一系列要求观察者获取现有物体知识的实验中,我们观察到,现实世界的物体具有一致的视觉尺寸,它们被绘制、想象和优先观看。重要的是,这个视觉尺寸与世界中物体的假设尺寸的对数成正比,最好的特征不是固定的视角,而是物体和周围空间框架的比例。类似于之前关于规范视角的文献,我们将这种一致的视觉尺寸信息称为规范视觉尺寸。
Real-world objects can be viewed at a range of distances and thus can be experienced at a range of visual angles within the visual field. Given the large amount of visual size variation possible when observing objects, we examined how internal object representations represent visual size information. In a series of experiments which required observers to access existing object knowledge, we observed that real-world objects have a consistent visual size at which they are drawn, imagined, and preferentially viewed. Importantly, this visual size is proportional to the logarithm of the assumed size of the object in the world, and is best characterized not as a fixed visual angle, but by the ratio of the object and the frame of space around it. Akin to the previous literature on canonical perspective, we term this consistent visual size information the canonical visual size.
