纯粹基于部分分解的物体识别理论没有考虑纹理、阴影和颜色信息的作用，也没有区分线画图形刺激准备中的风格因素。通过对常见物体的线条画、单色照片和彩色照片进行命名和验证实验，发现线条画的线条宽度、曝光量和对比度对命名潜伏期有影响，窄线宽和曝光量过大的线条命名潜伏期较长。对由专业艺术家绘制的具有不同程度表面细节的对象和由计算机辅助设计(CAD)系统制作的没有表面细节的对象的命名延迟进行了比较。艺术家组的平均命名潜伏期比CAD组快，但并不显著，观察到了显著程度的对象相关性。然而，在某些情况下，不同对象之间存在显著差异。这些在进一步的实验中被研究，在该实验中，从艺术家绘制的刺激中选择具有存在或不存在表面细节的共同属性的子集。研究发现，表面特征的存在导致了反应潜伏期的降低，即使是那些直观上可以被部分识别的物体也是如此。比较了照相和线画刺激命名的时间，观察到从线条到单色再到彩色刺激的命名潜伏期逐渐减少。在一项验证任务中，无论是在比较相同或不同模式的刺激时，都没有发现彩色或单色照片比线条画有显著优势。然而，有一种趋势是，不同模式的比较比相同模式的比较花费更长的时间。从人类视觉加工理论和物体识别的认知和计算模型两个方面对实验结果进行了讨论。
Theories of object recognition that are based purely on part decomposition do not take into account the role of textural, shading, and color information, nor do they differentiate between stylistic factors in the preparation of line-drawn pictorial stimuli. To investigate these factors, naming and verification experiments were performed using line drawings, monochrome photographs, and color photographs of common objects.For line drawings, it was shown that line width, exposure, and contrast affected naming latency, which increased for lines of narrow width and extremes of exposure. Naming latencies were compared for objects drawn by a professional artist, with varying degrees of surface detail, and objects produced by a computer-aided design (CAD) system, with no surface detail. The mean naming latencies for the artist set were faster than for the CAD set, though not significantly, with a significant degree of object correlation being observed. However, in certain cases there were significant differences between objects. These were investigated in a further experiment in which subsets with common properties of present or absent surface detail were selected from the artist-drawn stimuli. It was found that the presence of surface features resulted in lower response latencies even for those objects that intuitively could be recognized by parts alone.The time to name photographic and line-drawn stimuli was compared, and a progressive decrease in naming latency from line to monochrome to color stimuli was observed. In a verification task, no significant advantage for color or monochrome photographs over line drawings was found, either when comparing stimuli of equivalent or of different mode. However, there was a tendency for the comparison of different modes to take longer than the comparison of same modes. The results are discussed in terms of theories of human visual processing and cognitive and computational models of object recognition.
