  • Additional Positions at AU

    Affiliated Faculty, Department of Mathematics and Statistics, College of Arts and Sciences
  • Born in Brooklyn, Scott Parker began teaching at American University in 1974. He is interested in the quantitative aspects of our experiences and how we make evaluations and choices based on them. Examples include how loud we think sounds are, how valuable we think $50 is, how much we like a piece of music or art. He has also studied how people compare things – the loudnesses of two sounds or the attractivenesses of two paintings.
