ABSTRACT

Salient objects, such as abrupt-onsets, can capture attention even when nearly invisible. While the influence of explicit factors on such capture (e.g., task-goals) has been extensively investigated, the role of implicit control settings (e.g., probability cueing) is relatively unknown. We examined whether probability cueing affects attentional capture by masked onset cues. The target was more likely to appear on one hemifield of the display than the other. Saccade latencies indicated that capture by masked cues was identical across high and low-probability hemifields (Experiment 1). The same cues, when unmasked, captured attention more when presented in the high-probability hemifield (Experiment 2). We argue that capture by masked cues is not sensitive to implicitly learned biases, such as probability cueing. These findings support theories proposing that attentional control settings influence masked visual orienting only when set up explicitly.

摘要

突如其来的物体等突出物体即使在几乎看不见的情况下也可以吸引注意力。虽然已经广泛研究了显式因素对此类捕获（例如任务目标）的影响，但相对未知的隐式控制设置（例如概率提示）的作用。我们检查了概率提示是否通过掩盖的发作提示影响了注意力的捕获。目标更有可能出现在显示器的一个半场上，而不是另一个。扫视潜伏期表明，在高概率和低概率半场中，被掩盖线索捕获的效果是相同的（实验1）。当被揭露时，相同的线索在高概率半场中呈现时会引起更多关注（实验2）。我们认为，通过隐蔽线索的捕获对诸如概率提示之类的内隐学习的偏见并不敏感。
