摘要

水彩错觉(WCI)是一种颜色扩散错觉,由内外边界的对比引起,导致一种浅色错觉扩散的感觉,类似于浅色边界。这种错觉是一种强烈的图形线索,类似于,而且往往比其他格式塔线索更强烈。在我们目前的研究中,我们研究了WCI对亮度对比度匹配和不匹配区域的图像-背景分配的影响。目的是检查WCI的能力,以偏置图像的背景分配时,亮度的区域之间的变化。图像由一个正方形组成,由一个垂直的波浪轮廓线分成两部分。这些图像都没有WCI、WCI左、WCI右条件。参与者报告被探测的区域(左或右)是否看起来是这个数字。结果显示,当亮度匹配为白色(实验1)或灰色(实验3)时,WCI具有很强的效应,表明WCI具有很强的图形提示作用,能够对可逆刺激产生偏倚。然而,WCI未能将图像-背景与对比度区域相偏(实验2)。本研究首次展示了WCI如何在可逆的图像-背景刺激中与对比度区域相互作用。这些结果增强了我们对颜色扩散机制的理解,以及它们如何与亮度、对比度和感知组织相互作用。

Impact of the watercolor illusion and contrast on figure-ground reversibility.

The watercolor illusion (WCI), a color-spreading illusion induced by contrasting outer and inner borders, results in a perception of a pale illusory diffusion of a hue similar to the lighter border. This illusion is a strong figural cue similar to, and often stronger than, other Gestalt cues for figure-ground organization. In our present study, we examined the effect of the WCI on figure-ground assignment for regions with matched and non-matched luminance contrast. The goal was to examine the ability of the WCI to bias figure-ground assignment when luminance varies between regions of an image. Images consisted of a square divided into two parts by a vertical wavy contour. Each of these images had no WCI, WCI left, and WCI right conditions. Participants reported whether a probed region (either left or right) appeared to be the figure. Results showed a strong effect of the WCI when luminance was matched as white (Experiment 1) or gray (Experiment 3), demonstrating the WCI acts as a strong figural cue and is able to bias reversible stimuli. However, the WCI failed to bias figure-ground with contrasting luminance regions (Experiment 2). This study is the first to demonstrate how the WCI interacts with contrasting luminance regions in reversible figure-ground stimuli. These results enhance our understanding of color-spreading mechanisms and how they interact with luminance, contrast, and perceptual organization.

期刊介绍: The journal provides coverage spanning a broad spectrum of topics in all areas of experimental psychology. The journal is primarily dedicated to the publication of theory and review articles and brief reports of outstanding experimental work. Areas of coverage include cognitive psychology broadly construed, including but not limited to action, perception, & attention, language, learning & memory, reasoning & decision making, and social cognition. We welcome submissions that approach these issues from a variety of perspectives such as behavioral measurements, comparative psychology, development, evolutionary psychology, genetics, neuroscience, and quantitative/computational modeling. We particularly encourage integrative research that crosses traditional content and methodological boundaries.
