实验中，一个单一的目标模式是从多个背景干扰区分显示，某些阴影，二维（2-D）刺激符合顶光，多面体的解释可以快速（<80毫秒）和并行处理。然而，相同形状的无阴影线条图是连续处理的。强弹出不对称性和控制实验涉及阴影模式，没有熟悉的3-D解释表明，这种快速，并行处理是依赖于3-D形状的感知。此外，该过程可以以取决于附加线索是否有助于感知一致的3-D场景的方式受到上下文场景信息的影响。版权所有© 1996爱思唯尔科技有限公司
Experiments in which a single target pattern is discriminated from multiple background distractors show that certain shaded, two-dimensional (2-D) stimuli consistent with a top-lit, polyhedral interpretation can be processed fast (<80 msec) and in parallel. Unshaded line drawings of the same shapes, however, are processed serially. Strong pop-out asymmetries and control experiments involving shaded patterns that do not have familiar 3-D interpretations suggest that such fast, parallel processing is dependent upon perception of 3-D shape. Furthermore, this process can be influenced by contextual scene information, in a manner that is dependent upon whether the additional cues contribute to the perception of a consistent 3-D scene.
