Brain Structure Varies With Trust Level
A recent study shows differences in brain structure according to how trusting people are of others. The psychologists used two measures to determine the trust levels of 82 study participants. Participants filled out a self-reported questionnaire about their tendency to trust others. They also were shown pictures of faces with neutral facial expressions and asked to evaluate how trustworthy they found each person in the picture. This gave researchers a metric, on a spectrum, of how trusting each participant was of others. Researchers then took MRI scans of the participants' brains to determine how brain structure is associated with the tendency to be more trusting of others. What they found were differences in two areas of the brain. read more
