视觉注意力研究中的一个长期争论是，物理上显著的物体是否具有自动捕获注意力的能力。最近的证据支持一种混合模式。根据信号抑制假说，显著项目自动吸引注意，但可以通过自上而下的控制，以防止注意捕获主动抑制。虽然最近的证据表明，显着的项目可以被抑制，这些研究中的许多使用的颜色单例相对较低的显着性。因此，尚不清楚是否也可以抑制高度突出的颜色单例。目前的研究采用探针技术，以评估捕获的颜色单例在大的集大小（10或30个项目）。在四个实验中，我们没有观察到高度突出的颜色单例捕获注意力的证据，而是观察到它们被抑制在基线处理水平以下的证据。然而，我们发现了强有力的证据，地板效应的探测报告在高集的大小，这可以通过限制同时探测的项目的数量来减轻。总之，结果支持信号抑制假说。（PsycInfo数据库记录（c）2021阿帕，保留所有权利）
A longstanding debate in visual attention research has been whether physically salient objects have an automatic power to capture attention. Recent evidence has supported a hybrid model. According to the signal suppression hypothesis, salient items automatically attract attention but can be proactively suppressed via top-down control to prevent attentional capture. Although much recent evidence has suggested that salient items can be suppressed, many of these studies used color singletons with relatively low salience. It is therefore unknown whether highly salient color singletons can also be suppressed. The current study adapted the probe technique to assess capture by color singletons at large set sizes (10 or 30 items). In four experiments, we observed no evidence that highly salient color singletons captured attention and instead observed evidence that they were suppressed below baseline levels of processing. We did, however, find strong evidence of floor effects in probe report at high set sizes, which can be mitigated by limiting the number of items that are simultaneously probed. Altogether, the results support the signal suppression hypothesis.(PsycInfo Database Record (c) 2021 APA, all rights reserved)
