The MSU College of Communication Arts and Sciences is a leader in media psychology, the psychological study of the causes and consequences of humans' media use. The average American spends between three and a half to six hours a day with some kind of screen media, yet we still know very little about how this screen time affects us. ComArtSci's Allison Eden, an assistant professor of Communication, and David Ewoldsen, a professor of Media & Information, are investigating this phenomenon. Their research seeks to understand the roles, uses, processes, and effects of mediated communication.
