Abstract
The concept of cognition has undergone considerable extension, first, by intensive empirical study of representational systems and their role for the possession and application of cognitive capacities and second, by the turn to practical knowledge. By these two developments, the field of research on cognition has been opening with respect to which all eager attempts of demarcation between the humanities and the sciences seem to be outdated. This brings about institutional changes in the scientific landscape as can be seen in the current tendency to find interdisciplinary centres for the investigation of cognitive phenomena all over the world.
