Why is it called Thatcher Effect?

It is named after the then British prime minister Margaret Thatcher, on whose photograph the effect was first demonstrated. The effect was originally created in 1980 by Peter Thompson, Professor of Psychology at the University of York.

What is the Margaret Thatcher effect?

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.

Why do people look different upside down?

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. So when we’re presented with an upside-down, Thatcherised image, it’s not processed properly.

What are Thatchers called?

The names of the most common type, known as Hanging Ladders or Hangers, describes them well… These are short ladders, with metal spikes at the top, that stick in the thatched roof. Giving the thatcher extra reach. Another adaptation, often found in the West Country, is called a Biddle or Thatcher’s Horse.

Why are faces special?

Abstract. The ability to recognize individual faces is of crucial social importance for humans and evolutionarily necessary for survival. Consequently, faces may be “special” stimuli, for which we have developed unique modular perceptual and recognition processes.

What does the face inversion effect tell us?

According to the face(UI) effect, perception and recognition are better for faces presented upright (U) than for faces presented inverted (I). According to the face/object(UI) effect, inversion impairs the processing of faces more than the processing of nonfacial objects (e.g., buildings or cars).
