We all remember where we were as a child when a particular world event took place; depending on your age it could be the killing of J.F. Kennedy, the bombing of the twin towers in New York or the death of Diana, Princess of Wales. Chris French is Professor of Psychology at Goldsmiths and is interested in the nature of early childhood memories. Some memories when we interrogate them are clearly not believable and others can be implanted, so how reliable are our memories?
