视觉心理学是托福热门考点
今天Iris老师给大家讲解3个常考概念
还有敲有趣的栗子!一定要点开视频!
麦格克效应 McGurk effect
今年3月托福刚考过麦格克效应。这其实是英国心理学家麦格克的一项有趣的实验,证明当我们眼睛看到的信息和听觉接受的信息有冲突时,大脑更加倾向于相信视觉信息。
The McGurk effect is a perceptual phenomenon that demonstrates an interaction between hearing and vision in
speech perception. The visual information a person gets from seeing a person speak changes the way they hear the sound.
阈下刺激 subliminal perception
尽管视觉感知这么强大,它也会有“开小差”的时候。例如一个图片在我们面前一闪而过,我们可能完全没有意识到我们看到了这张图片。
这种图片刺激物被叫做阈下刺激,电影导演经常用这种方式来插入彩蛋,以娱乐观众。
Sometimes our perception of a stimulus can occur without our awareness: an image might appear and disappear before our eyes too quickly for us to notice that we saw it. This phenomenon – the perception of a stimulus just below the threshold of conscious awareness – is called subliminal perception.
知觉恒常性Perceptual constancy
当我们从不同角度观察同一物体时,物体在视网膜上投射的形状会不断变化。但是我们感受到的物体形状,色彩等却不会出现很大变化。
比如一个人从我们面前走过,他在视网膜上投影的大小会不断变化,但我们并不觉得他忽大忽小。
Perceptual constancy, the tendency of animals and humans to see familiar objects as having standard shape, size, color, or location regardless of changes in the angle of perspective, distance, or lighting. The impression tends to conform to the object as it is or is assumed to be, rather than to the actual stimulus.
