在这项研究中，变化检测范式被用来探索用于识别三维，新颖的物体的信息的性质。特别是，我们是否对部件标识或配置信息的更改敏感。实验1和2表明，对对象部分所做的结构性改变比对对象部分的形状或布置所做的改变更容易和更快地检测。由于像素的总变化而产生的方差在两个实验中都不能预测性能。实验3的结果显示了与实验1和2相同的模式，即使所使用的对象被改变，使部分身份信息更加突出。实验4表明，变化的物理大小不是这种结果模式的关键变量。这些研究结果进行了讨论有关的视觉表征和理论的对象识别的性质。
In this study a change-detection paradigm is used to explore the nature of the information used to recognize three-dimensional, novel objects. In particular, whether we are sensitive to changes in part identity or configuration information. Experiments 1 and 2 showed that configural changes made to the object parts were significantly easier and quicker to detect than changes made to the shape or arrangement of object parts. Variance due to the total change in pixels did not predict performance in either of the experiments. The results of Experiment 3 showed the same pattern as Experiments 1 and 2, even though the objects used were altered to make part identity information more salient. Experiment 4 demonstrated that the physical size of the changes is not the crucial variable for this pattern of results. These findings are discussed in relation to the nature of visual representations and theories of object recognition.
