The color phi phenomenon is the fact that, when apparent motion is induced between objects with different colors, the color of the apparently moving object abruptly changes midway along the path. It is a perceptual illusion described by psychologists Paul Kolers and Michael von Grünau in which a disembodied perception of motion is produced by a succession of still images. The color phi phenomenon is a more complex variation of the phi phenomenon. Kolers and von Grünau originally investigated the phenomenon in response to a question posed by the philosopher Nelson Goodman, who asked what the effect of the color change would have on the phi phenomenon.

  • 色彩飛現象(英語:Color phi phenomenon)指的是在顏色相異的對象之間誘發似動運動時,似動對象會突然在途中改變顏色的現象。這是心理學家保羅·科勒斯(Paul Kolers)和( Michael von Grünau) 所描述的一種感知錯覺,透過的靜止圖像產生對運動的無體感知(disembodied perception)。色彩飛現象是飛現象的複雜版本,科勒斯和馮格呂瑙最初是為了回答哲學家納爾遜·古德曼所提出的問題「顏色改變會對飛現象造成什麼影響」而研究此現象。 經典的飛現象實驗有一位觀看螢幕的參與者,實驗人員會接連在螢幕上投射兩個圖像。第一張圖像在幀的頂部描繪了一個藍點。第二幅圖像則在幀的底部描繪了一個紅點。圖像可快速地連續顯示,也可以每幀觀看幾秒鐘。在兩個圖像都投影完之後,實驗者會要求觀看的人描述他們所看到的內容。 如果兩個圖像結合某些間隔和計時的條件,觀看的人會報告在兩點的間隔中感覺到運動。第一點會似乎開始移動,然後「在其虛幻路徑的中間突然改變顏色」。 (zh)

  • The color phi phenomenon is the fact that, when apparent motion is induced between objects with different colors, the color of the apparently moving object abruptly changes midway along the path. It is a perceptual illusion described by psychologists Paul Kolers and Michael von Grünau in which a disembodied perception of motion is produced by a succession of still images. The color phi phenomenon is a more complex variation of the phi phenomenon. Kolers and von Grünau originally investigated the phenomenon in response to a question posed by the philosopher Nelson Goodman, who asked what the effect of the color change would have on the phi phenomenon. The classic color phi phenomenon experiment involves a viewer or audience watching a screen, upon which the experimenter projects two images in succession. The first image depicts a blue dot at the top of the frame. The second image depicts a red dot on the bottom of the frame. The images may be shown quickly, in rapid succession, or each frame may be given several seconds of viewing time. Once both images have been projected, the experimenter asks the viewer or audience to describe what they saw. At certain combinations of spacing and timing of the two images, a viewer will report a sensation of motion in the space between the two dots. The first spot will begin to appear to be moving, and will then "change color abruptly in the middle of its illusory path". (en)
