This study explores perceptual organisation and shape perception when viewing a tetragon and an additional element (a dot) that is located at varying positions and distances next to the tetragon. The aim of the study is to determine the factors that can alter the interpretation of object configuration and impact whether the presented tetragon is perceived as a diamond or a square. Methods used in this study are a forced-choice task as a subjective measurement and eye tracking as an objective measurement of perceptual processes. Overall, 31 stimuli were presented to the participants: a tetragon in two different sizes with an additional element (a dot) located inside or outside the object at three different positions at three distances. The results indicate significant changes in shape perception, depending on the location of the additional element. The results are complemented with eye movement analysis indicating that as the distance between the elements increases, there is a higher probability of either of the two shape interpretations and the gaze is less likely to be directed to the area between the stimuli. Furthermore, the subjective perception of shape is codetermined by the shape perception when the tetragon is presented without the additional element.

本研究探讨了观察四边形和位于四边形旁边不同位置和距离的附加元素（点）时的知觉组织和形状感知。该研究的目的是确定可以改变对对象配置的解释的因素，并影响所呈现的四边形是否被视为菱形或正方形。本研究中使用的方法是作为主观测量的强制选择任务和作为感知过程的客观测量的眼动追踪。总体而言，向参与者呈现了 31 种刺激：两种不同大小的四边形，以及位于对象内部或外部三个距离处的三个不同位置的附加元素（一个点）。结果表明形状感知的显着变化取决于附加元素的位置。结果与眼球运动分析相辅相成，表明随着元素之间的距离增加，两种形状解释中的任何一种的可能性更高，并且凝视不太可能被引导到刺激之间的区域。此外，当四边形在没有附加元素的情况下呈现时，形状的主观感知由形状感知共同决定。
