ABSTRACT
Gus Craik and I have been friends for many years and have followed very similar career paths. We both completed our Ph.D.s under the aegis of the British Medical Research Council, cut our theoretical teeth on the question of whether there is more than one kind of memory, and went on to do the piece of work for which we are probably best known in the early 1970s. We are both experimentalists at heart, basing our theoretical developments firmly on empirical evidence, and using experimental methods to investigate issues of practical significance, aging in Gus’s case and neuropsychology in mine.
