This festschrift honours Annette Karmiloff-Smith, a seminal thinker in the field of child development and a pioneer in developmental neuroscience. It brings together many of the researchers, collaborators and students who worked with Dr Karmiloff-Smith to show how her ideas have influenced and continue to influence their own research.

Michael S. C. Thomas is Professor of Cognitive Neuroscience at Birkbeck, University of London, UK.
