Summary
The article explains the Thatcher Effect, a psychological phenomenon where the brain struggles to recognize facial distortions when a face is presented upside down. The effect demonstrates how facial recognition processing can be fooled by simple visual manipulations, with the brain failing to detect that features like eyes and mouth have been inverted. First documented by Peter Thompson in 1980, this effect has inspired numerous studies on facial recognition and brain processing mechanisms.
Key quotes
· 3 pulledThe Thatcher Effect shows that when a face is upside down, but its features (eyes and mouth in this case) are themselves upside down, thus appearing right side up, the brain has a hard time recognizing the face to be tampered with, or wrong at all.
This is a great example of how the brain processes faces, and how it can be fooled by simple tricks.
This effect was first documented by Peter Thompson in 1980, and since then has spurred a series of experiments and studies on the topics of facial recognition and the brain.
