The well-known Stroop effect is usually attributed to the automaticity of word reading. Recently, Wühr and Waszak (2003) had participants name the color of one of two rectangles and found that words in the relevant object produced larger Stroop effects than did words in the irrelevant object or in the background. They attributed this difference to an object-based mechanism of attentional selection that amplifies processing of all the features of an attended object. However, in the displays used by Wühr and Waszak, occlusion suggested the presence of different depth planes. Hence, the increased Stroop effect could have resulted from perceiving the words to be in the same depth plane as the relevant object and not from perceiving the words to be parts of the relevant object. Two experiments tested between these accounts by using displays without monocular depth cues. The results of both experiments replicate those of Wühr and Waszak, supporting their object-based account.
著名的斯特鲁普效应通常归因于单词阅读的自动性。最近，武尔和瓦萨克（2003年）让参与者说出两个矩形之一的颜色，发现相关物体中的单词比不相关物体或背景中的单词产生更大的斯特鲁普效应。他们将这种差异归因于基于物体的注意力选择机制，该机制会放大被关注物体所有特征的处理过程。然而，在武尔和瓦萨克使用的显示中，遮挡表明存在不同的深度平面。因此，斯特鲁普效应的增加可能是由于将单词感知为与相关物体处于同一深度平面，而不是由于将单词感知为相关物体的一部分。两项实验通过使用没有单眼深度线索的显示来检验这些说法。两个实验的结果都重复了武尔和瓦萨克的结果，支持了他们基于物体的观点。
