    How can you change negative(消极的) thoughts? Many people suggest changing your attitude by thinking of something bright and happy.

However, scientists from Queen’s University in Canada said that there might be another way: by walking like a happy person.

“It is not surprising that our mood and the way we feel affects how we walk, but we want to see whether the way we move also affects how we feel,” explained Nikolaus Troje, the lead scientist, to The Independent.

Scientists believed that the way we remember emotional messages is affected by our mood. Those who suffer from depression (抑郁) remember negative information far more easily than active messages, especially when the information is about them.

In order to prove this, Troje and his team used cameras to observe 47 people walking on the treadmill (跑步机). Half of the people were encouraged to mimic (模仿) a depressive walking style, while the other half moved like a happy person. Walking speed was kept equal for both groups.

During the time on the treadmill, the scientists read out a list of active and negative words, asking people to decide whether or not each word described them well. Afterwards, people were asked to recite as many of the words as they could remember.

As expected, those who had been mimicking a depressed walk remembered more negative words than those that had been walking in a happy manner.

This finding means that our walk influences the way we treat information. And the scientists believe that using a happy walking style could help with treatment for depression.
