What is the Margaret Thatcher illusion?

We have trouble recognizing a familiar face when an image is turned upside down and when critical features, such as the eyes and mouth, are inverted.
Why is Thatcher effect scary?
The Thatcher effect highlights a flaw in how our brains work — we can’t process an upside-down face. According to The Naked Scientists, our brains are programmed to recognise faces the right way up. We create a mental map by recognising the face in pieces — eyes, mouth, and nose.
What is the Thatcher effect in psychology?
The Thatcher effect or Thatcher illusion is a phenomenon where it becomes difficult to detect local feature changes in an upside down face, despite identical changes being obvious in an upright face.
How does the Thatcher illusion work?
The Margaret Thatcher Illusion — which also gets called the Thatcher Effect, along with other names — occurs when a picture is turned upside down. But instead of changing everything in the picture, the effect happens when the features, like the mouth and eyes, are kept the right way up.

Abstract: Abstract The Thatcher illusion provides a compelling example of the perceptual cost of face inversion. The Thatcher illusion is often thought to result from a disruption to the processing of spatial relations between face features.
Is the Thatcher effect real?
The Thatcher effect or Thatcher illusion is a phenomenon where it becomes more difficult to detect local feature changes in an upside-down face, despite identical changes being obvious in an upright face.

Besides numerous studies in non-human species on face inversion, the Thatcher illusion has only recently been studied in macaques (Adachi et al. 2009). Adachi et al. used a habituation paradigm to demonstrate the Thatcher illusion in the macaque monkey.
Does the Thatcher effect apply to biological motion?
The basic principles of the Thatcher effect in face perception have also been applied to biological motion. The local inversion of individual dots is hard, and in some cases, nearly impossible to recognize when the entire figure is inverted.
