当使用线诱导而不是边缘诱导的虚幻轮廓刺激时，虚幻轮廓可以促进阈下实线的视觉检测（Dresp＆Bonnet，1995）的发现没有被重复（Salvano-Pardieu等人，2006）。相反，后一项研究的结果支持了空间线索的重要性。本研究旨在调查空间提示是否也有助于检测叠加在边缘引起的虚幻轮廓上的目标。在实验 1 中，目标线叠加在 Kanizsa 正方形的虚幻轮廓上，呈现在距目标精确或较远位置的点之间，或者呈现在均匀场（对照）上。对于控制来说，目标检测最差，其次是远距离点和 Kanizsa 条件，而对于精确提示点来说，目标检测最好。实验 2 复制了实验 1 中的条件（Kanizsa、精确提示点和控制），并附加了可能的亮度效果控制。这两个新条件与 Kanizsa 条件相匹配，可实现整体亮度和空间提示的精确性，而不会产生虚幻的轮廓。点条件下的性能最佳，对照条件下的性能最差，但 Kanizsa 和匹配亮度条件下的性能相同。在实验 3 和 4 中，呈现的刺激与 Drresp 和 Bonnet 使用的刺激更加匹配，但结果仍然证实了我们在实验 1 和 2 中获得的结果。总的来说，这些实验强烈表明，在边缘诱导的虚幻轮廓的情况下，空间提示而不是阈下求和也促进了检测。
Findings that illusory contours can facilitate visual detection of a subthreshold real line (Dresp & Bonnet, 1995) were not replicated, when line-induced instead of edge-induced illusory contour stimuli were used (Salvano-Pardieu et al., 2006). Rather, the results of the latter study supported the importance of spatial cues. The present study was designed to investigate whether spatial cueing might also facilitate detection of targets superimposed on edge-induced illusory contours. In Experiment 1, a target line was superimposed on the illusory contour of a Kanizsa square, presented between dots with a precise or distant location to the target, or on a homogeneous field (control). Detection of the target was poorest for the control, followed by the distant-dots and Kanizsa conditions, whereas it was best for precisely cueing dots. Experiment 2 replicated the conditions in Experiment 1 (Kanizsa, precisely cueing dots, and control) with additional controls for possible luminance effects. The two new conditions matched the Kanizsa condition for overall luminance and preciseness of spatial cueing without generating illusory contours. Performance was best in the dot condition and worst in the control, but the same across the Kanizsa and matched luminance conditions. In Experiments 3 and 4, the stimuli presented were matched more closely to those used by Dresp and Bonnet, but still the results confirmed those obtained in our Experiments 1 and 2. Together, these experiments strongly suggest that detection is also facilitated by spatial cueing rather than subthreshold summation, in the case of edge-induced illusory contours.
