Sir Frederick Bartlett, who was the head of our Department of Psychology in Cambridge, and he was really a great man, fantastic man. He had a wonderful Oxfordshire brogue, he was brought up in a village in the Cotswolds near Oxford, and he was just an avuncular, lovely man, you know, I was fond of him, and he wrote a wonderful book called "Remembering" in 1932, which is still read today, and he’s a great authority really on rather informal kinds of experiments where he got, for example, people to read a story or listen to a story and then they’d try to remember it a week later and then a week later after that, see how good they were at remembering it, and then he’d study how the memories changed in time, and he found that they moved towards the normal situation in that society. He was also interested in anthropology and belief systems in different cultures and the idea is that memories sort of really get edited and distorted and changed and he thought of memory as the creative reconstruction of the past from only fragmentary bits and pieces actually stored in the brain, and there were sort of laws by which memories changed through time roughly so that they matched your previous conceptions of the world and the society that you were in. So he saw memory as pretty unreliable really but obeying laws of error and I think that had a big affect on me because I then thought of perception as dynamic constructing so it was really a sort of Bartlettian idea but put into perception. And did that, do you see links between memory and perception then? I think there’s a big connection. Actually, it’s a silly thing this in psychology that memory and perception are absolutely linked. I mean when you’re looking at something, you’re using distant and immediate memories, topping up what you’ve just been seeing, for example, and, of course, you use knowledge right from childhood or even inherited in order to see, and yet memory and perception are studied completely differently. They’re normally in different laboratories, completely different people, when you have an examination of the student and entirely different pieces of paper that you have to write the answers on, and yet they’re completely linked and I think there should be much more work relating memory to perception in experimental psychology.
