are” has been viewed more than 33.5 million times.
Human and
animals show the same body language to convey emotions or information. For
example, we stretch our body out when we feel confident or ㄇ. On the
contrary, we curl our body to make ourselves smaller when feel depressed or
weak. In fact, because of hormones body pose can change mental conditions, and
mental conditions can change exterior behaviors. A study shows that after
people imitate high-power poses in 2 minutes, people’s testosterone raises 20%
and cortisol decreases 25%. These changed parameters reveal that people’s will feel
confident when they change their gestures. It means we may improve our performance
by displaying high-power motions. Therefore, we can try to alter our body language
or mimic the gestures of powerful people to optimize our performance.
