My thanks to the half-dozen-or-so people who responded to my previous request; the pointers were useful and interesting, but did not include the paper I was looking for... > ... The paper reported on > a psychology experiment that set out to determine the number of features > used by chess masters to recognize and/or classify random chess positions. > After a position had been set up (and not shown to the master), the master > got to ask yes/no questions until he thought he knew what the position was. > I think I remember that on average, it took about 70 questions to classify > a position. But I don't remember the author(s). Something in the back of my > head says it might have been Chase & Simon, or Nievergelt, or perhaps even > deGroot. It wasn't DeGroot (1965); his experiment was, how much of a seen position could be remembered. It also wasn't Chase & Simon (1973); their experiment was to identify featural chunks. Nor do the papers I've seen even refer to the result I'm after, which implies that the paper I want is probably after 1973. I have yet to track down Simon & Gilmartin (1973) which is not the paper I want but may have a reference. Could it have been Nievergelt, and if so, when? Any more clues are welcome. marcel@ads.com
