There may be something behind the idea of exposing a child to different races at a young age. According to a study conducted at the University of Massachusetts (Amherst), White babies with little exposure to Black people were extremely keen in gauging the difference in races outside of their own. Researchers also found that by the age of nine months, these babies processed emotions expressed by races other than their own in a different region of the brain. 

Essentially, the study suggests that at a very young age babies develop the ability to perceive what’s most important to them from their environment, then specialize in it. Researcher Lisa Scott said, “These results suggest that biases in face recognition and perception begin in preverbal infants, well before concepts about race are formed. It is important for us to understand the nature of these biases in order to reduce or eliminate them.” But, seeing how this study only involved Caucasian infants in a country where they are the majority, it may be something they have to leave their comfort zones to do.
