Whether scene gist perception occurs automatically and unconsciously has been the subject of much debate. In addition to demonstrating a new method that adapts the Mack and Rock (1998) inattentional blindness cross procedure to allow for sustained inattentional blindness over a large number of trials, we report evidence from a series of experiments that shows that canonical scene features reduce inattentional blindness to scenes by facilitating the extraction of scene gist. When attentional demands are high, the combination of canonical color, canonical luminance, and canonical orientation reduces rates of inattentional blindness. However, when attentional demands are reduced, canonical features are independently sufficient to facilitate gist extraction and to capture attention. These results demonstrate that canonical color, canonical luminance, and canonical orientation all contribute to scene gist perception, and that when attentional demands are high, only highly canonical stimuli are sufficient to capture attention.
场景要点感知是否自动且无意识地发生一直是诸多争论的主题。除了展示一种新方法，该方法改编了麦克和洛克（1998年）的无意视盲交叉程序，以在大量试验中实现持续的无意视盲，我们还报告了一系列实验的证据，这些证据表明典型场景特征通过促进场景要点的提取来减少对场景的无意视盲。当注意力需求较高时，典型颜色、典型亮度和典型方向的组合会降低无意视盲的发生率。然而，当注意力需求降低时，典型特征足以独立促进要点提取并吸引注意力。这些结果表明，典型颜色、典型亮度和典型方向都有助于场景要点感知，并且当注意力需求较高时，只有高度典型的刺激才足以吸引注意力。
