精神分裂症患者感知世界的方式在很大程度上是神秘的。理解和欣赏视觉世界始于对基本视觉特征的感知，而这种视觉特征在这种精神障碍中会发生改变。然而，基本视觉特征在艺术欣赏等功能活动中发挥的作用尚不清楚。本研究探讨了视觉特征操控对精神分裂症患者 (n=29) 和正常对照者 (n=30) 艺术美感的影响。三件艺术作品——《星夜》（梵高）、《蒙娜丽莎》（达芬奇）和一张自然风景照片（匿名）——在色彩（去除颜色）、空间频率内容（低频或高频通过）和视觉噪声水平（添加噪声）方面进行了处理。受试者通过对每件作品进行单独评分（I 至 7）并对所有作品从最美丽到最不美丽进行排名，来判断原创和视觉特征操纵的艺术品的美感。对于三件原创艺术作品，患者和对照组的平均评分和排名相似。然而，当原始作品的视觉特征被操纵时，患者的美丽评级变化明显较小。对视觉特征操纵的敏感性降低表明，通常用于艺术中生动和动态表达的基本视觉信号的调制在精神分裂症中可能没有得到充分重视。 (C) 2008 Elsevier B.V. 保留所有权利。
The way schizophrenia patients perceive the world is largely mysterious. Understanding and appreciating the visual world begins with the perception of basic visual features, which is altered in this mental disorder. Yet, the roles basic visual features play in functional activities such as appreciation of art are unclear. This study examined the effects of visual feature manipulation on beauty perception of art in schizophrenia patients (n=29) and in normal controls (n=30). Three pieces of art - The Starry Night (Van Gogh), Mona Lisa (Da Vinci) and a natural landscape photograph (anonymous) - were manipulated in terms of their coloration (removal of color), spatial frequency content (low or high-frequency pass) and visual noise level (with added noise). Subjects judged the beauty of the original and visual-feature-manipulated artworks by rating each piece individually (I to 7) and by ranking all pieces from most to least beautiful. For the three original art pieces, averaged ratings and rankings were similar in patients and controls. However, when the visual features of the original pieces were manipulated, changes in the beauty ratings were significantly smaller in patients. The reduced sensitivity to visual feature manipulations suggests that the modulation of basic visual signals, often used for vivid and dynamic expressions in art, may be under-appreciated in schizophrenia.
