在本研究中，我们测试了阈下快速启动线索是否以自下而上或自上而下的控制方式捕获注意。对于我们的测试，我们改变了搜索的目标对比度极性（即，灰色背景下的暗或亮目标）。在自下而上的假设，我们的研究结果表明，阈下启动线索捕获注意力独立的搜索目标对比度极性（实验1），这种效果是不强的目标，匹配的搜索目标对比度极性（实验2）。事实上，即使是与不去反应相关的被忽略的线索也会以显著性驱动的方式吸引注意力（实验3）。对于阈上线索，我们发现注意捕获只有线索与匹配的对比极性，反映偶然捕获（实验4）。结果指向一个特定的作用，阈下突然发作的注意力捕获。
In the present study, we tested whether subliminal abrupt-onset cues capture attention in a bottom-up or top-down controlled manner. For our tests, we varied the searched-for target-contrast polarity (i.e., dark or light targets against a gray background) over four experiments. In line with the bottom-up hypothesis, our results indicate that subliminal-onset cues capture attention independently of the searched-for target-contrast polarity (Experiment 1), and this effect is not stronger for targets that matched the searched-for target-contrast polarity (Experiment 2). In fact, even to-be-ignored cues associated with a no-go response captured attention in a salience-driven way (Experiment 3). For supraliminal cues, we found attentional capture only by cues with a matching contrast polarity, reflecting contingent capture (Experiment 4). The results point toward a specific role of subliminal abrupt onsets for attentional capture.
