卡尼莎三角：为什么我们“看见”并不存在的边？
Kanizsa triangle: why do we 'see' an edge that isn't there?
当几个缺角的圆盘围成一圈，大脑会自动补全出白色三角形及其清晰边界，这叫主观轮廓。它说明知觉是大脑主动“填充”而非被动记录视网膜图像。
When notched disks surround a gap, the brain completes a white triangle with crisp borders—a subjective contour. Perception is the brain actively filling in, not passively recording the retinal image.

缪勒-莱尔错觉：为什么带箭头的线看起来长短不一？
Muller-Lyer illusion: why do arrow-headed lines look unequal?
两条等长线段因两端箭头朝向不同而被误判长短，一种解释是大脑把向外的角当成凸角、向内的角当成凹角，按三维角落深度自动“校正”了长度。它揭示深度线索会干扰二维判断。
Two equal lines look unequal by arrow direction; one explanation is the brain reads outward fins as convex and inward as concave corners, auto-correcting length by perceived 3D depth. It shows depth cues hijack flat judgments.

为什么静止的图看起来却在动？（似动错觉）
Why does a static image seem to move? (apparent motion)
当亮点依次快速闪现，大脑会把它们连成连续运动，这就是似动（如霓虹招牌、电影原理）。它说明运动知觉可以由离散信号“编造”出来，而非必须真实位移。
When dots flash in sequence fast enough, the brain links them into smooth motion—apparent motion (the basis of neon signs and film). Motion perception can be 'invented' from discrete signals, not requiring real movement.

为什么月亮在地平线时看起来比在头顶大？
Why does the moon look bigger on the horizon than overhead?
月亮错觉中，地平线处的月亮被树木、建筑等参照物对比显得大，而高空无参照。实际角直径几乎不变，大脑对距离与大小的估计被语境“骗”了。
In the moon illusion, a horizon moon looks larger against trees and buildings, while the high moon has no reference. Its angular size is nearly constant; the brain's size-distance estimate is fooled by context.

为什么白墙在阴影下仍显得是白的？（颜色恒常性）
Why does a white wall in shadow still look white? (color constancy)
颜色恒常性让我们根据光照环境自动校正物体颜色，使白墙在明暗下都判为白。它极大帮助识别，但也会骗人——同一条裙子在不同光下会被看成不同颜色。
Color constancy lets us auto-correct for lighting so a white wall reads white in shadow or sun. It aids recognition but can trick us—the same dress is seen as different colors under different light.
