The research suggests that negative evaluations based on appearance may influence which candidate will lose an election, more so than positive evaluations.
UC San Diego computer scientists found that people first fixate on the left of the center of the nose and then the center of the nose to determine if a face is familiar. Looking at two spots, such as the nose and eye, does not improve recognition, but allows for better performance. Understanding how humans recognize faces may help crea...
