Dynamic System Theory (DST) has made its way from mathematics and physics into all disciplines of the mind and brain sciences. DST provides a holistic and situated approach to think about the mind, the neuron, the brain, the person, the group, society and how each of them interacts with the environment. Over the course of the semester I want to discuss system thinking in different areas of the mind, brain, and social sciences. In particular, we will spent two sessions each on DST in psychology, neuroscience, cognitive science, and linguistics plus one on sociology. The first session provides an overview and the second session focuses on a specfic model or study, respectively. Finally, we spent the last two session reflecting on dynamical explanations from the perspective of philosophy of science/mind. Although there is a math-heavy side to DST the seminar tries to focus on a) cross-disciplinary system-theoretical thinking and b) how this can facilitate interdisciplinary exchange through a shared theoretical framework and shared terminology.
