我们研究了焦点注意和并行执行的特征梯度检测之间的关系。我们发现，即使在执行并发的表格识别任务时，也可以检测到特征梯度而没有可测量的性能损害，尽管表格识别任务涉及焦点注意，从而从特征梯度附近移除注意资源。这一结果有力地表明，关于视觉场景中显著边界和奇点的某些知觉可以在没有资源有限的过程的帮助下完成，例如焦点注意，这意味着可能存在两种不同的知觉能力(一种专注，另一种不是)，能够将互补的种类的视觉信息同时带到我们的意识中。
We investigated the relationship between focal attention and a feature-gradient detection that is performed in a parallel manner. We found that a feature gradient can be detected without measurable impairment of performance even while a concurrent form-recognition task is carried out, in spite of the fact that the form-recognition task engages focal attention and thus removes attentive resources from the vicinity of the feature gradient. This outcome suggests strongly that certain perceptions concerning salient boundaries and singularities in a visual scene can be accomplished without the aid of resource-limited processes, such as focal attention, and, by implication, that there may exist two distinct perceptual faculties (one attentive, the other not) that are able to bring complementary kinds of visual information simultaneously to our awareness.
