通常隐含在视觉搜索任务的解释是假设目标的检测是由低层次的视觉处理的特征编码属性1，2。但更高层次的过程也被牵连，因为视觉搜索能力在深度平面3中得到增强，当二维形状被解释为三维形式时4，5。在这里，我们操纵双目视差降低视觉搜索，使其他相同的功能成为表面的一部分，通过知觉完成，使他们不太清楚地区分为目标和干扰。我们的研究结果表明，视觉搜索有很少或根本没有访问的处理水平的特征提取，但必须有一个更高层次的表面表示的输入过程。
OFTEN implicit in the interpretation of visual search tasks is the assumption that the detection of targets is determined by the feature-coding properties of low-level visual processing1,2. But higher level processes have also been implicated as visual search ability is enhanced in a depth plane3 of when two-dimensional shapes are interpreted as three-dimensional forms4,5. Here we manipulate binocular disparity to degrade visual search, so that otherwise identical features become parts of surfaces through perceptual completion, rendering them less clearly distinguishable as targets and distractors. Our results indicate that visual search has little or no access to the processing level of feature extraction but must have as an input a higher level process of surface representation.
