This summer Professor Dan Kersten was awarded the Koffka Medal by the Department of Psychology at the University of Giessen, Germany. At the award ceremony, Kersten presented on "The scientific power of a perceptual demonstration." The Kurt-Koffka award honors scientists who advanced the fields of perception or developmental psychology to an extraordinary extent. The award is in remembrance of Kurt Koffka, who was well-known as a pioneer of Gestalt Psychology, in particular in the fields of perception and child development. Koffka was a professor of psychology in Giessen for 16 years, from 1911 to 1927.
