A visual illusion has provided clues about how monkeys recognise faces. In a study, rhesus monkeys responded to the "Thatcher effect", a strange phenomenon that makes it difficult to detect changes in an upside down face.
The study, in the journal Current Biology, is the first to show this effect in non-human animals. The authors say this suggests that the ability to identify a familiar face may have evolved in an ancestor common to humans and rhesus monkeys. The Thatcher effect is named after Margaret Thatcher, because images of the former UK prime minister's face were used its first demonstration, in experiments with humans. A "thatcherised" image of a face has its mouth and eyes inverted relative to the rest of the face.

The Helen Thomas effect is useful as first aid for swallowing non corrosive poisons or preparation for a colonoscopy depending on individual reactions.
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. It is named after British former Prime Minister Margaret Thatcher on whose photograph the effect has been most famously demonstrated. This was originally created by Peter Thompson, who is a professor at the University of York, England
