视觉感知似乎没有共同因素，即视觉任务中的表现彼此之间的相关性很弱。视觉错觉也发现了类似的结果。对于患有改变大脑功能的疾病（例如精神分裂症）的人来说，人们可能会想到常见的视觉因素。例如，受疾病影响更严重的患者，例如更强的阳性症状，可能会表现出更大的错觉程度。在第一个实验中，我们使用了一组七种视觉错觉和心理意象问卷。七种错觉的错觉强度在患者和对照组之间没有显着差异。此外，不同错觉和心理意象之间的相关性很低。在第二个实验中，我们测试了 59 名患者（大部分是门诊患者）的 10 种视错觉。至于第一个实验，患者和对照者对除一种视错觉之外的所有视错觉都表现出相似的易感性。此外，不同的幻觉、症状或药物类型之间没有显着相关性。因此，精神分裂症患者对视错觉的感知似乎基本完好。
There seems to be no common factor for visual perception, i.e., performance in visual tasks correlates only weakly with each other. Similar results were found with visual illusions. One may expect common visual factors for individuals suffering from pathologies that alter brain functioning, such as schizophrenia. For example, patients who are more severely affected by the disease, e.g., stronger positive symptoms, may show increased illusion magnitudes. Here, in the first experiment, we used a battery of seven visual illusions and a mental imagery questionnaire. Illusion magnitudes for the seven illusions did not differ significantly between the patients and controls. In addition, correlations between the different illusions and mental imagery were low. In the second experiment, we tested 59 patients (mostly outpatients) with ten visual illusions. As for the first experiment, patients and controls showed similar susceptibility to all but one visual illusion. Moreover, there were no significant correlations between different illusions, symptoms, or medication type. Thus, it seems that perception of visual illusions is mostly intact in schizophrenia.
