Welcome to Northeastern University’s Social Interaction Lab! Our lab is led by Dr. Judith Hall with the help of graduate students and many amazing undergraduate research assistants. As the name suggests, we are interested in social interaction. We examine this topic in a variety of ways, using myriad methods and theories. We explore the many fascinating factors that influence the way we interact with others as well as the way we perceive others during these interactions.
