Abstract

In the prodromal phase of schizophrenia, severe alterations of the visual appearance of the environment have been found, accompanied by a state of intense anxiety. The present study considers the possibility that these alterations really exist in the appearance of objects, but that healthy people do not see them. The image of the world that we see is continuously deformed and fragmented by foreshortenings, partial overlapping, and so on and must be constantly reassembled and interpreted; otherwise, it could change so much that we would hardly recognize it. Since pleasure has been found to be involved in visual and cognitive information processing, the possibility is considered that anhedonia (the reduction of the ability to feel pleasure) might interfere with the correct reconstruction and interpretation of the image of the environment and alter its appearance. The possibility is also considered that these alterations might make the environment hostile, might at times evoke the sensation of being trapped by a predator, and might be the cause of the anxiety that accompanies them. According to some authors, they might also induce delusional ideas, in an attempt to restore meaning in a world that has become chaotic and frightening.

焦虑和精神分裂症之间的可能联系以及快感缺乏的可能作用。
在精神分裂症的前驱期,环境的视觉外观发生了严重的改变,并伴有强烈的焦虑状态。目前的研究考虑了这样一种可能性,即这些变化确实存在于物体的外观中,但健康人看不到它们。我们所看到的世界形象,由于前缩、部分重叠等原因,不断地变形和破碎,必须不断地重新组合和解释;否则,它可能会发生很大的变化,以至于我们几乎认不出它。由于已经发现快乐与视觉和认知信息处理有关,因此人们认为快感缺乏(感觉快乐的能力降低)可能会干扰对环境图像的正确重建和解释,并改变其外观。还有一种可能性是,这些变化可能会使环境变得不友好,有时可能会引起被捕食者困住的感觉,也可能是伴随它们而来的焦虑的原因。根据一些作者的说法,它们还可能引发妄想,试图在一个已经变得混乱和可怕的世界中恢复意义。
