Subjective similarity holds a prominent place in many psychological theories, influencing diverse cognitive processes ranging from attention and categorization to memory and problem solving. Despite the known importance of subjective similarity, there are few resources available to experimenters interested in manipulating the visual similarity of shape, one common type of subjective similarity. Here, across seven validation iterations, we incrementally developed a stimulus space consisting of 360 shapes using a novel image-processing method in conjunction with collected similarity judgments. The result is the Validated Circular Shape space, the first Validated Circular Shape space comparable to the commonly used "color wheel", whereby angular distance along a 2D circle is a proxy for visual similarity. This extensively validated resource is freely available to experimenters wishing to precisely manipulate the visual similarity of shape. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
主观相似性在许多心理学理论中占有重要地位，影响着从注意力和分类到记忆和解决问题等多种认知过程。尽管主观相似性的重要性已被广泛认识，但对于那些有兴趣操纵形状视觉相似性的实验者来说，可用的资源却很少，而形状视觉相似性是一种常见的主观相似性。在这里，我们通过结合新颖的图像处理方法和收集的相似性判断，在七个验证迭代中逐步开发了一个由 360 个形状组成的刺激空间。其结果是 Validated Circular Shape 空间，这是第一个与常用的“颜色轮”相媲美的 Validated Circular Shape 空间，其中沿着二维圆的角度距离是视觉相似性的代理。这个经过广泛验证的资源可供希望精确操纵形状视觉相似性的实验者免费使用。
