Grapheme-color synesthetes experience colors when they see printed letters of the alphabet. Currently, we tested four "projector" synesthetes, whose colors evoked by graphemes have sensory support or quale and appear to be restricted spatially to the letters like real colors. We use three different kinds of puzzle pictures that contained hidden letters, which require 30 s or more for nonsynesthetes to identify. Grapheme-color projector synesthetes recognize them three times faster and report that the colors were evoked before conscious letter recognition, clueing them as to what the letters were. Subjectively, the synesthetic subjects reported that they also saw mirror-reversed letters in the same colors as nonreversed letters which enabled them to read mirror-reversed text at thrice the normal speed. We conclude that in some synesthetes colors are evoked preconsciously early in sensory processing.
字形-颜色联觉者在看到字母表中的印刷字母时会体验到颜色。目前，我们测试了四名“投影仪”联觉者，他们由字形引发的颜色具有感官支持或特质，并且在空间上似乎像真实颜色一样局限于字母。我们使用了三种不同类型的拼图图片，其中包含隐藏的字母，非联觉者识别这些字母需要30秒或更长时间。字形-颜色投影仪联觉者识别它们的速度快三倍，并报告说在有意识地识别字母之前就引发了颜色，这为他们提示了字母是什么。主观上，联觉受试者报告说，他们还看到了与正写字母颜色相同的镜像字母，这使他们能够以正常速度的三倍阅读镜像文字。我们得出结论，在一些联觉者中，颜色在感觉处理的早期就会在意识之前被引发。
