This is the first SFB that was born out of our Faculty and the third in Germany given to a Faculty of Psychology. We now have the means to study for four years the behavioral, developmental, neural, and clinical aspects of extinction learning. If successful, the SFB could run for up to 12 years in total. Countless insights, publications, careers, and positions will be born out of that. The new SFB has 19 project teams. On board are psychologists, medical scientists, theoretical neuroscientists, and biologists from the RUB, and from Essen, Dortmund and Marburg.
