项目摘要

This research investigated how the subjects with various observation-experiences perceive the visual illusions (assimilation and contrast) during their early observing stages. The observation-results in these early stages have been almost canceled as these preliminary responses were unstable. However, I believe that the important clue would be found in these early observations for the above visual illusions having various appearances to the subjects with various visual experiences.Results are as follows. The estimated magnitudes of illusion (brightness/hue assimilation and contrast) indicated that naive subjects perceived less assimilation in the first observation. However, repeated observations caused the same subjects to perceive assimilation and contrast more and more with different progression. And the subjects reported that they were able to see gray test-figure (TF)'s opposite brightness/hue (contrast) induced by inducing-figure (IF)'s brightness/hue more easily and directly. On the other hand, assimilation allowed black/white or colored IF (background) to appear vaguely through almost transparent gray TF.When the subjects were instructed to view patterns with more contrastive or more assimilative style, the subjects tended to shift their perceptions in the direction as instructed. However, these perception-shifts are controlled basically by the width-ratios or cycle-variations of TF to IF in stimulus patterns. In conclusion, assimilation and contrast are greatly affected by subjects' experiences in observing stripe-patterns. For instance, naive subjects develop their perceptions distinctively in the ranges between assimilation and contrast (from only contrast at first, then to both assimilation and contrast). Further, the subjects, naive and experienced, also transfer their perceptions in the direction either to more assimilative or to more contrastive through their different cognitive grasping-styles

这项研究调查了各种观察经验的受试者如何在早期观察阶段感知视觉错觉（同化和对比度）。这些早期阶段的观察结果几乎被取消，因为这些初步反应不稳定。但是，我认为，在这些早期观察中会发现上述视觉幻觉的重要线索，这些视觉幻觉具有各种视觉体验的主题，如下所示。幻觉的估计幅度（亮度/色相同化和对比）表明，在第一个观察结果中，天真的受试者认为同化较少。但是，反复的观察结果导致相同的受试者感知同化，并越来越多地与不同的进展对比。受试者报告说，他们能够看到诱导图（如果）的亮度/色调引起的灰色测试图（TF）的相反的亮度/色调（对比度）。另一方面，如果（背景）通过几乎透明的灰色TF出现，同化允许黑色/白色或有色人种。当指示受试者以更对比或更同化的样式查看图案时，受试者倾向于按照指示的方向转移他们的看法。但是，这些感知转移基本上由TF的宽度比率或循环差异控制为if刺激模式。总之，同化和对比受到受试者在观察条纹模式中的经验的极大影响。例如，幼稚的受试者在同化和对比之间的范围内鲜明地发展了他们的看法（从最初仅对比到同化和对比度）。此外，幼稚和经验丰富的受试者也将他们的看法转移到方向上，要么通过其不同的认知握把式式的对比度更加同化或更对比
