Is top-down control necessarily scarce, slow, and hence unimportant in visual selection? Here we outline the risks of downplaying top-down control. Contrary to Theeuwes' review, we suggest that not all sources of attention map onto a unitary attentional priority map. Goals and search habits may influence where and how people deploy attention, respectively. Because goals have modulatory effects on sensory processing, their impact on attention is broad and not always deliberate. In addition, when multiple sources influence attention, top-down control often dominates over less deliberate forms of attention. We agree with Theeuwes that selection history can drive attention independent of explicit goals. Nonetheless, top-down control remains a cornerstone of visual selection.
自上而下的控制在视觉选择中必然是稀缺、缓慢且因此不重要的吗?在此,我们概述了轻视自上而下控制的风险。与特维斯的综述相反,我们认为并非所有注意力来源都映射到一个单一的注意力优先级图谱上。目标和搜索习惯可能分别影响人们注意力的部署位置和方式。由于目标对感觉处理有调节作用,它们对注意力的影响广泛且并不总是刻意的。此外,当多种来源影响注意力时,自上而下的控制通常比不太刻意的注意力形式占主导地位。我们同意特维斯的观点,即选择历史可以独立于明确目标驱动注意力。尽管如此,自上而下的控制仍然是视觉选择的基石。
