Did You Know the Brain Processes Expressions of Fear First?

Did you know the brain processes expressions of fear first?


According to one study at Vanderbilt University , it takes a much shorter response time for people to process and react to fearful expressions than any other expression. This study used a method involving static images being shown to one eye, while the other received flashing images. Those with nuetral expressions seemed to take a shorter time response time than those with smiling expressions. The most readily and rapidly received response came from the expressions of fear. It is believed that this has to do with the amount of white showing in the eyes as well as the fear response taking a shortcut to the brain. This may especially effect those with autism, who have a more difficult time assessing others expressions.
