Yueran Yang

Associate Professor of Psychology

Summary

I am an Assistant Professor with a joint appointment with the Psychology Department and the Interdisciplinary Social Psychology Ph.D. Program at the 夜色视频. I received my Ph.D. in both Psychology and Statistics from Iowa State University. My research interests include interrogated confessions and eyewitness identification.

Research Interests

Both psychology and mathematics fascinate me. Psychology inspires my interests in understanding human mind and behavior, while mathematics refines my way of thinking. My research combines these two.

As a social psychologist with a strong statistical background, I have focused my research on building mathematical models and applying statistical methods to answer questions in psychology, particularly questions that have real-world impact. The overarching goal of my program of research is to understand the psychological causes of convictions of the innocent.

To date, among more than 300 wrongful convictions that have been exposed through post-conviction DNA testing, approximately 91 percent were caused by false confession, eyewitness misidentification, or -- in some cases -- both (). Accordingly, my primary areas of research are within the domains of criminal confessions and eyewitness identification.
