Recent evidence for separate forms of attention for different visual attributes seems to conflict with Duncan's "integrated competition" theory of visual attention. To resolve this conflict, we established attention-operating characteristics for four pairs of visual discriminations. While one task was common to every pair, the other tasks were different and concerned different visual attributes. In all pairs, the common task exhibited the same performance-resource function, whether the other tasks involved entirely similar, partially similar, or entirely dissimilar visual attributes. These results confirm that visual attention conforms exactly to the predictions of a single, integrated resource.
最近关于不同视觉属性存在不同形式注意力的证据，似乎与邓肯的视觉注意力“整合竞争”理论相冲突。为了解决这一冲突，我们确定了四对视觉辨别任务的注意力操作特征。虽然每对任务中有一个任务是相同的，但其他任务各不相同，且涉及不同的视觉属性。在所有任务对中，无论其他任务涉及的是完全相似、部分相似还是完全不同的视觉属性，共同任务都表现出相同的绩效-资源函数。这些结果证实，视觉注意力完全符合单一整合资源的预测。
