在视觉意识中,图形浮雕是如何表现的?当然不是作为一个“深度图”,但也许是作为一个地图的地方表面的态度。在这里,我们考虑的可能性,观察者可能会代替,或同时,表示局部表面形状,相对于运动的几何不变。观察者判断局部表面形状,在一个雕塑作品的图片,在五点分类尺度。类别是帽脊鞍车辙杯平,其中“平”表示没有形状。我们发现,观察员很容易执行这样的任务,与完整的分辨率的形状指数规模(帽脊鞍车辙杯),并具有良好的自我一致性,在几天内。观察者之间存在显著差异。在一组10天真的观察者,我们发现,分散的判断峰值在鞍类。这一发现可能与主题的历史有关--阿尔贝蒂(1827)在他所谓的局部表面形状的详尽目录中遗漏了鞍形范畴。
How is pictorial relief represented in visual awareness? Certainly not as a “depth map,” but perhaps as a map of local surface attitudes. Here we consider the possibility that observers might instead, or concurrently, represent local surface shape, a geometrical invariant with respect to motions. Observers judge local surface shape, in a picture of a piece of sculpture, on a five-point categorical scale. Categories are cap–ridge–saddle–rut–cup–flat, where “flat” denotes the absence of shape. We find that observers readily perform such a task, with full resolution of a shape index scale (cap–ridge–saddle–rut–cup), and with excellent self-consistency over days. There exist remarkable inter-observer differences. Over a group of 10 naive observers we find that the dispersion of judgments peaks at the saddle category. There may be a relation of this finding to the history of the topic—Alberti's (1827) omission of the saddle category in his purportedly exhaustive catalog of local surface shapes.
