手指識字之特異色覺與正常色覺的比較:一個個案研究

Comparison between Normal Color Sense and Extrasensory Perception Color Sense in Color Adaptation Task: A Case Study

摘要


本研究企圖區辨功能人在特異功能下之色彩感覺與正常視覺下之色彩感覺的差異,藉著這些比較,我們相信能更進一步理解產生特異視覺信息場的運作特性與相對應腦功能的活動方式。實驗結果發現,外界提供的光源在功能人的特異視覺屏幕中可能扮演照明的角色,因此,在紅光適應下,特異視覺所感應到的顏色產生偏紅現象,失去正常色彩視覺應有的色彩恆常性。但是,該功能人在適應紅光之後,正常色彩視覺感受仍保持色彩恆常性。而且功能人在特異屏幕出現的時候,特異視覺的影像往往遮蔽了正常視野的視覺。這些結果可能意味著,手指識字的特異視覺與正常視覺在大腦中產生交互作用,但是基本上這兩種視覺意識狀態仍是經由不同的大腦管道所引發。

並列摘要


By using the color adaptation procedure, we compare the difference of color appearances in normal color sense and extrasensory perception (ESP) color sense (recognition by finger condition). We find that, the subject, who has ESP ability, can keep color constancy in normal visual condition after red-light adaptation, but not in recognition by finger condition. This result suggests that ESP color vision may be illuminated by external light source through the normal visual pathway. We discuss the possible relationship between properties of special screen in ESP color vision and brain activity in last paragraph.
