共同因素无处不在。例如，智力有一个公因子g。在视觉中，这些共同因素的证据要弱得多。例如，视错觉幅度彼此之间仅弱相关。在这里，我们调查了错觉是否像知觉学习一样具有超特异性。首先，我们测试了艾宾浩斯错觉的19种变体，这些变体在颜色、形状或质地上都不同。不同变体的错觉幅度之间的相关性大多是显着的。其次，我们重新分析了以前实验中的数据集，其中在四种亮度条件下测试了10种错觉，并发现每种错觉的不同亮度条件之间存在显着相关性。不过，这十种幻术之间的关联，却非常微弱。第三，在四个方向上测试了五种视错觉。同样，每种错觉的四个方向之间存在显著相关性，但不同错觉之间没有相关性。错觉之间的弱相关性表明，被测错觉之间不存在唯一的共同机制。我们认为，大多数错觉都有自己的因素。
Common factors are ubiquitous. For example, there is a common factor, g, for intelligence. In vision, there is much weaker evidence for such common factors. For example, visual illusion magnitudes correlate only weakly with each other. Here, we investigated whether illusions are hyper-specific as in perceptual learning. First, we tested 19 variants of the Ebbinghaus illusion that differed in color, shape, or texture. Correlations between the illusion magnitudes of the different variants were mostly significant. Second, we reanalyzed a dataset from a previous experiment where 10 illusions were tested under four conditions of luminance and found significant correlations between the different luminance conditions of each illusion. However, there were only very weak correlations between the 10 different illusions. Third, five visual illusions were tested with four orientations. Again, there were significant correlations between the four orientations of each illusion, but not across different illusions. The weak inter-illusion correlations suggest that there is no unique common mechanism for the tested illusions. We suggest that most illusions make up their own factor.
