In the present study, we conducted two experiments (Experiment 1: 35 participants, M = 29; SD = 8.4; Experiment 2: 36 participants, M = 25; SD = 6.1) with the intention to explore whether underlying perceptual grouping operations and illusory form perception generate dissociable priming effects when Kanizsa-like figures are presented as primes and the rotated inducers as controls under conditions of restricted awareness. Using five different stimulus onset asynchronies (SOA conditions, Experiment 1: 27, 40 and 53 ms; Experiment 2: 27, 80 and 227 ms), we displayed masked illusory and groping primes that could be congruent or incongruent in their orientation with subsequent probe stimuli (vertical vs. horizontal). We found significant priming effects in both Experiment 1 and 2 (p < .001, η2p = .31 and p = .016, η2p = .16, respectively), but, crucially, no significant priming differences between illusory and grouping primes across SOA conditions. Overall, our results are important in showing that a dissociation of the percept generated by the grouping of the inducers from that generated by the illusory form is crucial in the study of illusory form perception under conditions of restricted awareness. In addition, they provide further evidence of perceptual organization operations occurring under very restrictive awareness conditions.
在本研究中，我们进行了两项实验（实验1：35名参与者，M = 29；SD = 8.4；实验2：36名参与者，M = 25；SD = 6.1），旨在探究当类似卡尼兹图形作为启动刺激呈现，旋转诱导物作为对照，在意识受限条件下，潜在的知觉分组操作和错觉形状知觉是否会产生可分离的启动效应。使用五种不同的刺激呈现间隔（SOA条件，实验1：27、40和53毫秒；实验2：27、80和227毫秒），我们展示了被掩蔽的错觉和分组启动刺激，它们在方向上可能与随后的探测刺激（垂直与水平）一致或不一致。我们在实验1和实验2中均发现了显著的启动效应（分别为p <.001，η2p =.31和p =.016，η2p =.16），但至关重要的是，在不同SOA条件下，错觉启动刺激和分组启动刺激之间没有显著的启动差异。总体而言，我们的结果对于表明在意识受限条件下，诱导物分组产生的知觉与错觉形状产生的知觉之间的分离在错觉形状知觉研究中至关重要具有重要意义。此外，它们还为在非常受限的意识条件下发生的知觉组织操作提供了进一步的证据。
