Elementary students attending ethnically diverse schools are less likely to be racially biased than students at homogeneous schools, according to a new study by two University of Maryland, College Park researchers.

Co-authored by human development professor Melanie Killen and postdoctoral researcher Heidi McGlothlin, the study ? published in the October issue of the journal Child Development ? showed first- and fourth-graders pictures of familiar peer situations at 13 suburban schools in Maryland and Virginia.
