James Hampton has been a leading researcher for the last 38 years on the psychology and cognitive science of concepts. Starting with a paper in Nature in 1973, he has published over 50 scientific papers in top psychology journals, with over 1000 citations, as well as contributing some 30 chapters and abstracts to other published titles. His particular research expertise concerns problems of vagueness in concepts and word meanings, and problems of conceptual combination. He has actively disseminated his research and ideas, through publications and conference presentations at international meetings, and also through teaching undergraduate and graduate students at City University London, where he is Professor of Psychology, and at universities in the US (Stanford, Cornell, Chicago, Yale) and Europe. He has a range of collaborative research links in Europe, particularly in France, Italy, Belgium and Sweden. His research expertise includes both qualitative and quantitative methods in psychology, and he teaches ANOVA and multivariate statistical methods at City University. He also has interests in the philosophy of language and logic, with a particular interest in vagueness.
His standing as a researcher has been recognized by the award of a Nuffield Foundation Fellowship in 1984, a Senior Fellowship from the French Ministry for Higher Education and Research in 1995, and a Fulbright Commission Senior Research Scholarship in 1996. He serves on the editorial board of several journals, including Cognition, and the Journal of Experimental Psychology: General, and has also served on the Research Grants Board of the UK Economics and Social Research Council.
