David R. Olson is University Professor Emeritus at the Ontario Institute for Studies in Education at the University of Toronto, Canada. He has authored more than 300 articles and 20 books, including The World on Paper (Cambridge, 1994), Psychological Theory and Educational Reform: How School Remakes Mind and Society (Cambridge, 2004) and The Mind on Paper (Cambridge, 2016). His research focuses on children's developing consciousness of their own and others' mental states and on the role that language and literacy play in this development.
'When David R. Olson asked his apparently pre-verbal 1-year-old to get her shoes, she promptly complied - much to his surprise. That incident planted the seed for a deep enquiry. Had she truly understood him? What does it mean to ascribe understanding to such a young child? We also need to consider who is doing the ascribing. Are young children able to ascribe understanding to themselves? And what about animals and computers? Drawing on the contributions of philosophers, linguists, and psychologists, David R. Olson proposes that understanding is a uniquely human capacity, slowly acquired as part of a web of language practices. His book is a provocative and original contribution to the study of children's theory of mind.' Paul Lansley Harris, Harvard Graduate School of Education, USA
