It is possible to construct an ambiguous line drawing representing several objects partly hidden behind another object. This article deals with two problems: (a) What are the necessary and sufficient conditions for ambiguity to occur? (b) How can the response frequencies of the completions of ambiguous drawings be explained? Whether completions occur or not, the predictions based on the coding theory, better termed the structural information theory, have been discussed in a previous article (Buffart, Leeuwenberg, & Restle, 1981). It is shown here that the theory also specifies the conditions for ambiguity to occur. The theory describes all possible interpretations of a drawing and selects those interpretations or completions to which subjects will respond. A direct relation between the response frequencies and the possible theoretical descriptions of each response is shown to exist. Two one-parameter models describing the behavior of subjects each fit the response frequencies measured in two experiments with 25 drawings. It is argued that the type of ambiguity that is studied in both experiments generally appears during the perceptual process. The character of the theoretical descriptions indicates that guidance of perceptual behavior by interpretations might occur.
构建一幅表示几个部分隐藏在另一个物体后面的物体的模糊线条画是可能的。本文探讨两个问题：（a）产生模糊性的必要和充分条件是什么？（b）如何解释模糊图形完成情况的反应频率？无论是否会出现完成情况，基于编码理论（更确切地说是结构信息理论）的预测已在之前的一篇文章中讨论过（Buffart、Leeuwenberg和Restle，1981年）。本文表明该理论还规定了产生模糊性的条件。该理论描述了一幅画的所有可能解释，并选择出受试者会做出反应的那些解释或完成情况。反应频率与每个反应的可能理论描述之间存在直接关系。描述受试者行为的两个单参数模型分别拟合了在对25幅画进行的两个实验中测得的反应频率。有人认为，这两个实验中所研究的模糊性类型通常出现在感知过程中。理论描述的特点表明，解释可能会对感知行为产生引导作用。
