　　 Scientists think that most animals can’t see colous. The world is black and white to them. To find out if the dogs could see colours, scientists gave dogs food evey time they played a certain piece of music. The dog got ready to eat only when they heard this piece of music. They did not get ready to eat when they heard other piece of music.

Then the scientists gave the dogs food every time they showed them a certain colour. The dog got ready to eat when they saw this colour .The colours were all the same to them.

Colours are not all the same to the monkeys, however, for example, if we put food in a red box and do this every day, a monkey will always go to the red box to get the food. If we then put food in a blue box, the monkey won’t go to it.
