Chris Cummins is a Lecturer at the University of Edinburgh. He previously worked at Bielefeld University, having received his PhD from the University of Cambridge. His research interests include the pragmatic interpretation of quantity expressions, and how this bears upon reasoning and decision-making; he has also published on the topics of presupposition, speech acts and metaphor. He is the author of Constraints on Numerical Expressions (OUP 2015). Napoleon Katsos is a Reader in Experimental Pragmatics at the University of Cambridge. He was among the first generation of PhD researchers to be trained in experimental pragmatics and took part in related networks, such as Euro-XPrag, XPrag-UK, and XPrag-De. He is interested in how we learn, process, and use the meaning of words and sentences, with emphasis on quantification and implicature. He draws relevant evidence from linguistic theory and experimental psychology, including sentence processing and typical or atypical language acquisition by monolingual or bilingual children.
