     Research shows that humans switch from selfish to unselfish behaviour when they are watched. Do you?
    A picture of a set of eyes on a computer screen can cause a change in
the way people act. Even images of eyes on a charity donation, collection
box encourage people to be unselfish, because people put more money in a
collection box that has a picture of eyes on it than they do when a flower
symbol is on the box.
    Manfred Milinski from the Max-Planck Institute for Evolutionary
Biology in Germany and Bettina Rockenbach of the University of Berlin,
the authors of a new study, found that people act better when they are
being watched because they feel they will be rewarded for good behaviour.
Their report also referred to other research showing that this response of behaving well when watched is
somehow coded into humans and people respond this way unconsciously, or without realizing it.
     It is not just humans that act unselfishly when they are being watched. A fish called the grooming fish cleans
other fish. When other fish are around, it is gentler. When no other fish are around, however, the grooming fish
bites chunks from the fish it is supposed to be cleaning.
     The researchers suggest that the best way to get people to behave in the correct way is to make them feel
watched. This could be the reason for the success of a famous American army poster. On it was a picture of
an elderly man staring fiercely and pointing, it appeared, to the person who was looking at the poster. Under the
picture was the caption "I Want You". It encouraged hundreds of thousands of young American men to join the
army during the Second World War to fight the Germans and Japanese.
