In this paper, Professor Ann Lewis, of the School of Education, University of Birmingham, reviews the literature and current research on pupils’ perceptions of others’ difficulties in learning. She focuses, in particular, on three strands: children’s perceptions about other people and their traits; children as ‘naïve’ biologists, attempting to explain growth and development in others; and children’s responses to and use of cues based on achievement and ideas about ability. In a wide‐ranging discussion, this article explores work on theory of mind and notes the different ways in which children explain learning difficulties in others at various ages. In her conclusion, Professor Lewis makes three key points: there is a need to supplement experimental work in this area with good quality, classroom‐based studies; more effort should be devoted to finding ways of accessing children’s views and perceptions in authentic and reliable ways; and staff working in inclusive classrooms are ideally placed to contribute to the development of research in this area.
