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.

Research by Scotland Yard published in a London newspaper, has proven that knife crime in London is a serious non – white phenomenon, with 165 of the 225 under- 18s accused of knife crime in the past three months being from the black or other non – white groups．

According to Scotland Yard, only 60 of the 225 crimes were white．Despite being a small minority of the knife holding criminals, whites did, however, make up the single largest group of victims of knife crime．

According to the Scotland Yard report, whites made up 222 of the 637 victims of knife crime over the last three months．This number could probably be higher, as 292 victims were not identified by race．

This month Scotland Yard Deputy Commissioner Sir Paul Stephenson suggested knife crime has replaced drug selling as the top concern for London police．

Sir Paul said so as he announced a specialist knife crime unit to deal with teenagers carrying knives in the capital．It will use a team of 75 specialist officers to find criminal group members and their supporters．

Detective Inspector, George Rhoden, president of the National Organisation of Black Law Enforcement Executives said, “In the black community we have all noticed that there is major concern about gun and knife crime．Clearly we are not the only part of the community affected by the problem of children who have no fathers, but parental responsibility should be of major concern.”

Around 59 percent of black Caribbean children and 54 percent of mixed – race youngsters are looked after by a lone parent．In the white British population, the number is 22 percent．

A．there are more whites than blacks as victims

B．there are more blacks than whites as victims

C．blacks make up the smallest group of criminals
