International Interdisciplinary Computational Cognitive Science Summer School (#IICCSSS) is now on Mastodon! We are an annual five-day summer school for computational #cogsci students (but also for people from adjacent fields interested in computational approaches to brain and cognition). In 2023, IICCSSS will take place in Tübingen, Germany, September 11–15. We have planned a number of exciting talks and workshops, as well as a hackathon!
