We have perceived some difference between an object color that previously rememberedand a color perceived when you are looking at the exact same object. Our aim of this studyis to understand this internal shift of the color perception. Because it has been consideredthat such internal shift of the color perception is due to the categorization of color in theperception, we investigated the internal coding processes for the categorization through theprocesses of color memorization in the psychophysics and by a method of brain imaginganalysis.We found that normal color visions formed color categories exclusively and their borderswere not ambiguous, but that color deficiencies categorized colors with ambiguous borders.There was no significant cortical activity specified the color categorization under different stimulus conditions for both subjects.These indicate that the internal operations of the color sensations per se may occur beforethe coding process. It is however quite difficult to measure its cortical activity.

我们已经察觉到先前记住的物体颜色与当您查看完全相同的物体时感知到的颜色之间存在一些差异。我们这项研究的目的是了解颜色感知的这种内部转变。因为人们认为颜色感知的这种内部转变是由于感知中颜色的分类造成的，所以我们通过心理物理学中的颜色记忆过程和脑成像分析的方法研究了分类的内部编码过程。我们发现正常的色视觉专门形成颜色类别，并且它们的边界不模糊，但颜色缺陷将颜色分类为模糊的。 两个受试者在不同的刺激条件下没有明显的皮层活动指定颜色分类。这表明颜色感觉本身的内部操作可能发生在编码过程之前。然而，测量其皮质活动相当困难。
