Comparative Biocognition is an interdisciplinary and integrative discipline within the field of Cognitive Science. This is also reflected in our teaching activities and the contents of our interdisciplinary courses. The fascination for organismic approaches and their relevance for a better understanding of the evolution of communication, cognition and plasticity are shown to students. Our goal is to open the mind for empirical and analytical views of complex communciation systems, underlying cognitive mechanisms, and cultural complexity to gain a better understanding of the impact of endocrinological, genetic and social factors on plastic processes. In addition, we teach methodological approaches to tackle and develop scientific hypotheses and questions on the proximate and ultimate level.
