摘要

本研究继续探讨十字形(由两对方向相反的缪勒-莱尔翼组成)上下文干扰物引起的长度错觉效应是否可以用两种不同(即缪勒-莱尔翼和填充空间)几何范围错觉的综合表现来解释。在心理物理实验中,一对翅膀的亮度被随机改变,而另一对翅膀的亮度则保持不变。实验中使用了两种不同的分散方向--当亮度不变的翅膀构成十字架的右侧时,分散方向为左侧;反之,分散方向为右侧。为了分别评估不同亮度条件下穆勒-莱尔错觉的表现,在第一轮实验中,两个相同方向的分散注意力的十字架被连接到侧面刺激终止器上。在随后的四个系列实验中,我们在其中一个侧面刺激终结器上贴上了单个分散注意力的十字架(方向不同),并使用了恒定亮度和背景亮度的不同组合。为了解释实验数据,我们使用了之前开发的定量模型的基本计算原理,这些模型是假设的视觉机制,是产生缪勒-莱尔错觉和填充空间错觉的基础。结果表明,理论计算的结果充分接近了对所有刺激物进行修改后得到的实验曲线,这有力地支持了这样一种观点,即这两种错觉的共同表现可被视为决定所研究错觉特征的主要因素之一。

Combined manifestation of two geometric visual illusions

Combined manifestation of two geometric visual illusions

The present study continued to investigate whether the effects of length misperception caused by cross-shaped (formed by two pairs of the oppositely oriented Müller-Lyer wings) contextual distractors can be explained by the combined manifestation of two different (i.e., the Müller-Lyer and filled-space) geometric illusions of extent. In psychophysical experiments, the luminance of one pair of wings was randomly changed, while the luminance of the other pair remained constant. Two different distractor orientations were used—when the wings with constant luminance formed the right side of the cross or the left side, otherwise. To separately evaluate the manifestation of the Müller-Lyer illusion under different luminance conditions, two distracting crosses of the same orientation were attached to the lateral stimulus terminators in the first series of experiments. In the following four series, a single distracting cross (with different orientation) was attached to one of the lateral stimulus terminators and various combinations of the constant and background luminance were used. To interpret the experimental data, we used the basic computational principles of previously developed quantitative models of hypothetical visual mechanisms underlying the emergence of the Müller-Lyer illusion and the filled-space illusion. It was shown that the results of theoretical calculations adequately approximate the experimental curves obtained for all modifications of stimuli, which strongly supports the suggestion that the joint manifestations of these two illusions can be considered among the main factors determining the features of the illusion investigated.

期刊介绍: The journal Attention, Perception, & Psychophysics is an official journal of the Psychonomic Society. It spans all areas of research in sensory processes, perception, attention, and psychophysics. Most articles published are reports of experimental work; the journal also presents theoretical, integrative, and evaluative reviews. Commentary on issues of importance to researchers appears in a special section of the journal. Founded in 1966 as Perception & Psychophysics, the journal assumed its present name in 2009.
