快乐的小猪们：猪在愉悦环境中表现较为积极

According to the research, pig same with human, have the ability to have complicated feeling. Scientist wish to improve the welfare of animals by proving this truth.

The pigs are taught that reward is related to 'ring(sound)' and apple; the thing that dislike by pigs is related to noise produce by the rubbing of plastic bag.

Then, the pigs are divide into two groups. One is in good condition which provide a larger space, more food and more toys. However, another group is locked in a bored and small fence. After that, the workers would send some blur message and the two sound that the pigs learnt. Their reaction is being observed.

According to the professor, the pigs live in the better environment are optimistic, they seen the noise as reward as well, they would come closer and wish to get reward, in contrast, another groups of pigs are pessimistic.
