当物体信息在空间中被广泛分离时，视觉系统能够识别物体，如Kanizsa类型的幻觉轮廓(IC)所揭示的那样。注意参与ICs的知觉是一个重要的课题，本研究考察了ICs的加工是否以及如何受到分心物的干扰。在无中央动态斑块或存在中央动态斑块的情况下，研究了虚幻圆的细小变形和短变形的区分，区分的难度分为三个水平(容易、中等和困难)。在简易和中等条件下，没有牵引物的反应时间(RT)明显短于有牵引物的情况。无干扰时的正确率显著高于易分心时的正确率，且分心反应与非分心反应的反应正确率之差随着任务难度的增加而显著减小。这些结果表明，当更多的注意力资源可用时，对IC的感知更容易受到分心的影响。本研究结果支持注意参与了对IC的知觉，IC加工的分心与知觉负荷有关。
The visual system is capable of recognizing objects when object information is widely separated in space, as revealed by the Kanizsa-type illusory contours (ICs). Attentional involvement in perception of ICs is an important topic, and the present study examined whether and how the processing of ICs is interfered with by a distractor. Discrimination between thin and short deformations of an illusory circle was investigated in the absence or presence of a central dynamic patch, with difficulty of discrimination varied in three levels (easy, medium, and hard). Reaction time (RT) was significantly shorter in the absence compared to the presence of the distractor in the easy and medium conditions. Correct rate (CR) was significantly higher in the absence compared to the presence of the distractor in the easy condition, and the magnitude of the difference between CRs of distracted and non-distracted responses significantly reduced as task difficulty increased. These results suggested that perception of ICs is more likely to be vulnerable to distraction when more attentional resources remain available. The present finding supports that attention is engaged in perception of ICs and that distraction of IC processing is associated with perceptual load.
