In this work, we discussed and counter-commented van der Helm's comments on our previous paper (Pinna and Conti, , , , 149), where we demonstrated unique and relevant visual properties imparted by contrast polarity in eliciting amodal completion. The main question we addressed was: "What is the role of shape formation and perceptual organization in inducing amodal completion?" To answer this question, novel stimuli were studied through Gestalt experimental phenomenology. The results demonstrated the domination of the contrast polarity against good continuation, T-junctions, and regularity. Moreover, the limiting conditions explored revealed a new kind of junction next to the T- and Y-junctions, respectively responsible for amodal completion and tessellation. We called them I-junctions. The results were theoretically discussed in relation to the previous approaches and in the light of the phenomenal salience imparted by contrast polarity. In counter-commenting van der Helm's comments we went into detail of his critiques and rejected all of them point-by-point. We proceeded by summarizing hypotheses and discussion of the previous work, then commenting on each critique through old and new phenomena and clarifying the meaning of our previous conclusions.
在这项工作中，我们对范德·赫尔姆对我们之前论文（皮纳和孔蒂，年份，页码）的评论进行了讨论和反驳。在之前的论文中，我们展示了对比极性在引发非模态完型时所赋予的独特且相关的视觉属性。我们所探讨的主要问题是：“形状形成和知觉组织在诱发非模态完型中起什么作用？”为回答这个问题，我们通过格式塔实验现象学研究了新颖的刺激。结果表明，对比极性比良好连续、T 型交点和规则性更具主导性。此外，所探索的限制条件揭示了一种分别紧邻 T 型和 Y 型交点的新型交点，它们分别负责非模态完型和镶嵌。我们将它们称为 I 型交点。我们根据先前的方法并鉴于对比极性所赋予的现象显著性对结果进行了理论探讨。在反驳范德·赫尔姆的评论时，我们详细阐述了他的批评意见，并逐点予以驳斥。我们先总结了先前工作的假设和讨论内容，然后通过新旧现象对每一条批评意见进行评论，并阐明我们先前结论的含义。
