<p> Report</p><p>I held the S.T. Lee Fellowship at the School of Advanced Study from May 1st until May</p><p>31st. During my stay, I focused on the completion of two pieces of work, one a research paper documenting the emergence of various expressions of ignorance, both non-verbal and verbal, in young children [Harris, P.L., Bartz, D.T. & Rowe, M.L. </p><p>(2017). Young children communicate their ignorance and ask questions. </p><p>Proceedings of the National Academy of Sciences, 114, 7884-7891] and the other a chapter reviewing recent findings on young children’s learning from others’ testimony. [Harris, P.L., Koenig, M. A., Corriveau, K. H., & Jaswal, V.K. (in press). </p><p>Cognitive foundations of learning from testimony. Annual Review of Psychology, 69].</p><p>When my timetable permitted, I attended the weekly research seminars at the </p><p>Institute of Philosophy. I also gave three talks at U.K universities outside of London, as detailed below:</p><p>1. Why do children doubt magic but believe in miracles? 1.00 pm, Friday, 5th May, </p><p>Psychology Department, Lincoln University.</p><p>2. Why do children doubt magic but believe in miracles? 2.00 pm, Friday 12th </p><p>May. Lecture theatre, Institute of Cognitive and Evolutionary Anthropology, </p><p>Oxford.</p><p>3. Young children’s developing conception of knowledge and ignorance: Work in </p><p> progress. 11.00 am, Monday 15th May, Board Room, Philosophy Faculty, </p><p>Raised Faculty Building, Sidgwick Avenue, Cambridge. At the School, I participated in a workshop on: The Role of Ignorance: Using metacognitive attributions in epistemology and psychology held on Tuesday 23rd May </p><p>2017 which was co-organized by three members of the Institute of Philosophy </p><p>(Corine Besson, Ophelia Deroy, and Nicholas Shea). My own paper was entitled: “I don’t know”: Ignorance and question-asking as engines for cognitive development. </p><p>I attach details of the workshop program. This was an excellent opportunity for me to discuss my recent work with philosophers as well as psychologists.</p><p>Finally, I was invited to speak at a 2-day international conference organized by the </p><p>Swiss Center for Affective Sciences held at the Campus Biotech in Geneva, to mark </p><p>12 years of interdisciplinary research on emotion. I presented a paper entitled </p><p>Missing Persons on Thursday May 18th.</p><p>I am very grateful for the invitation from the School. It was an excellent opportunity for me to engage with both new and existing colleagues. I particularly enjoyed the stimulating, multi-disciplinary atmosphere at the Institute of Philosophy.</p><p>Paul L.
