Hubert Hermans (1937) is a professor in Personality Psychology. In 1973 he became an associate professor of psychology at the University of Nijmegen and in 1980 full professor at the same university. Since 2002 he is president of the International Society for Dialogical Science (ISDS) and since 2006 editor-in-chief of the International Journal for Dialogical Science (IJDS). His dissertation (1967) was on Motivation and achievement and resulted in two psychological tests: The Achievement Motivation Test for adults and The Achievement Motivation Test for children. In the nineties of the last century, he developed the dialogical self-theory, inspired by the American pragmatism of William James and the dialogical school of the Russian literary scholar Mikhail Bakhtin.
