Visual illusions are a gateway to understand how we construct our experience of reality. Unfortunately, important questions remain open, such as the hypothesis of a common factor underlying the sensitivity to different types of illusions, as well as of personality correlates of illusion sensitivity. In this study, we used a novel parametric framework for visual illusions to generate 10 different classic illusions (Delboeuf, Ebbinghaus, Rod and Frame, Vertical-Horizontal, Zöllner, White, Müller-Lyer, Ponzo, Poggendorff, Contrast) varying in strength, embedded in a perceptual discrimination task. We tested the objective effect of the illusions on errors and response times, and extracted participant-level performance scores (n=250) for each illusion. Our results provide evidence in favour of a general factor underlying the sensitivity to different illusions (labelled Factor i). Moreover, we report a positive link between illusion sensitivity and personality traits such as Agreeableness, Honesty-Humility, and negative relationships with Psychoticism, Antagonism, Disinhibition, and Negative Affect.
视觉错觉是理解我们如何构建现实体验的一个途径。不幸的是，一些重要的问题仍然没有答案，例如，不同类型错觉敏感性的共同因素假设，以及错觉敏感性的人格相关性。在这项研究中，我们使用了一种新的视觉错觉参数框架，生成了 10 种不同的经典错觉（Delboeuf、Ebbinghaus、Rod and Frame、Vertical-Horizontal、Zöllner、White、Müller-Lyer、Ponzo、Poggendorff、Contrast），它们的强度不同，嵌入在知觉辨别任务中。我们测试了错觉对错误和反应时间的客观影响，并为每个错觉提取了参与者水平的表现分数（n=250）。我们的结果为不同错觉敏感性的共同因素提供了证据（标记为因子 i）。此外，我们报告了错觉敏感性与人格特质之间的正相关关系，例如宜人性、诚实谦逊，以及与精神病态、对抗性、去抑制和负性情绪的负相关关系。
