“So many things affect academic outcomes that are not under our control,” said Anna V. Fisher, an associate professor of psychology at Carnegie Mellon and the lead author of the study, which was published in Psychological Science. “But the classroom’s visual environment is under the direct control of the teachers. They’re trying their best in the absence of empirically validated guidelines.”

In the early years of school, children must learn to direct their attention and concentrate on a task. As they grow older, their focus improves. Sixth graders, for example, can tune out extraneous stimuli far more readily than preschoolers, the study’s authors noted.
