Scientists in Sweden have figured out why it’s so difficult to keep a straight face if others around you are grinning away. It’s your unconscious mind taking control. The researchers at Uppsala University had volunteers look at pictures of expressionless, happy, and angry faces. In return they were told to adopt blank, happy, or angry expressions. When they had to meet a smile with a frown, or a frown with a smile, they had trouble. Twitching in the subjects’ faces — measured with electronic equipment — indicated they simply didn’t have control of their muscles. It’s believed that there’s a shortcut to the part of the brain that recognizes faces and expressions that bypasses the area responsible for conscious processing.

This will help my science fair project a bit, but how do I test this? I’m only in 7th grade!!!!
p.s i am in 7th grade too:)
i’m in 5th grade and i’m doing this!!!!!!!!!!!!!! My friend is going to walk a couple yeard behind me, and she will have a notebook and i will have a notebook. Since we will pass the same people, she will write down how many people smiled at her and i will do the same. and FYI: its already a universal fact that a positive person will attract another positive person.when you smile at someone,you give off positive emotions which pull at the same energies in the reciving person.
