盲人（以前有视力）能够分析、描述和图形化地表现出大量的高对比度视觉图像，这些图像被重新翻译成音乐形式。我们向这些受试者展示了随机分类的物体和城市场景的摄影图像的音乐变换，其中一些描绘了建筑和其他地标，这些地标可能有助于导航到特定目的地的路线。我们的盲人受试者能够使用声音表征来构建一个有意识的心理图像，这是通过他们通过绘画来描绘视觉目标的能力来揭示的。我们注意到视觉系统整合来自连续注视的信息以形成一个在眼球运动中稳定的表征的方式与连续图像帧的方式之间的相似性。（编码在声音中），其描绘图像的不同部分被整合以形成无缝的心理图像。最后，我们讨论了一个专业的音乐家进行结构分析的音乐作品的方式之间的深刻的相似之处，以将其结构与音乐形式的感知和我们的盲人主体在隔离结构特征时所使用的策略，这些结构特征共同揭示了视觉形式的身份。
Blind (previously sighted) subjects are able to analyse, describe and graphically represent a number of high-contrast visual images translated into musical form de novo. We presented musical transforms of a random assortment of photographic images of objects and urban scenes to such subjects, a few of which depicted architectural and other landmarks that may be useful in navigating a route to a particular destination. Our blind subjects were able to use the sound representation to construct a conscious mental image that was revealed by their ability to depict a visual target by drawing it. We noted the similarity between the way the visual system integrates information from successive fixations to form a representation that is stable across eye movements and the way a succession of image frames (encoded in sound) which depict different portions of the image are integrated to form a seamless mental image. Finally, we discuss the profound resemblance between the way a professional musician carries out a structural analysis of a musical composition in order to relate its structure to the perception of musical form and the strategies used by our blind subjects in isolating structural features that collectively reveal the identity of visual form.
