Common ground is essential for successfully coordinating and carrying out any joint activity. At the level of large-scale social interaction, notions of CG are useful for understanding social dynamics, or public opinion formation. At the level of dyadic interaction, more fine-grained aspects of CG help explain nuanced phenomena relating to linguistically-oriented communication (LC), among other things. Despite its importance and centrality to many issues in many academic fields, the notion of common ground is highly elusive. This CRC is a multi-disciplinary effort, anchored in linguistics, towards a better understanding, wider applicability and empirical validation of notions of CG. CRC 1718 is structured around three core areas – Cognition, Grammar, and Communication – and brings together researchers from a wide variety of backgrounds, including theoretical and computational linguistics, psycholinguistics, psychology, rhetoric, literary studies, and biological anthropology.
