物体识别理论的不同之处在于，它们认为物体表征仅由物体的形状或形状和表面细节介导，如果表面细节是表征的一部分。特别地，已经提出，颜色信息可能仅在非常特殊的情况下有助于识别对象，但在良好的观看条件下的基本级别对象识别期间没有帮助。在这项研究中，我们收集了规范性数据（命名协议，熟悉度，复杂性，和图像判断）的260个黑色和白色线条画的Samplegrass和Vanderwart的对象数据库，然后将数据进行比较，完全相同的形状，但添加了灰度纹理和表面细节（集2），和颜色（集3）。还记录了一些数据。虽然添加纹理和不带颜色的阴影只能稍微提高对象的命名一致性分数，但添加颜色信息无疑提高了命名准确性并加快了正确的响应时间。如先前的研究所示，颜色提供的优势对于具有诊断颜色和结构相似形状的物体（如水果和蔬菜）更大，但对于具有和不具有单一诊断颜色的人造物体也可以观察到。这些观察结果表明，在正常条件下，基本水平的“日常”对象识别是由颜色信息的存在促进，并支持一个“形状+表面”模型的对象识别，颜色是一个组成部分的对象表示。此外，新的刺激（集2和3）和相应的规范数据提供了有价值的材料，为广泛的实验和临床研究的对象识别。
Theories of object recognition differ to the extent that they consider object representations as being mediated only by the shape of the object, or shape and surface details, if surface details are part of the representation. In particular, it has been suggested that color information may be helpful at recognizing objects only in very special cases, but not during basic-level object recognition in good viewing conditions. In this study, we collected normative data (naming agreement, familiarity, complexity, and imagery judgments) for Snodgrass and Vanderwart's object database of 260 black-and-white line drawings, and then compared the data to exactly the same shapes but with added gray-level texture and surface details (set 2), and color (set 3). Naming latencies were also recorded. Whereas the addition of texture and shading without color only slightly improved naming agreement scores for the objects, the addition of color information unambiguously improved naming accuracy and speeded correct response times. As shown in previous studies, the advantage provided by color was larger for objects with a diagnostic color, and structurally similar shapes, such as fruits and vegetables, but was also observed for man-made objects with and without a single diagnostic color. These observations show that basic-level 'everyday' object recognition in normal conditions is facilitated by the presence of color information, and support a 'shape + surface' model of object recognition, for which color is an integral part of the object representation. In addition, the new stimuli (sets 2 and 3) and the corresponding normative data provide valuable materials for a wide range of experimental and clinical studies of object recognition.
