Recall of Random and Non Random Chess Positions in Strong and Weak Chess Players

Abstract

Three random and three meaningful chess positions were presented to strong and weak chess players during a 60 seconds time period. Recall was found to be superior in strong players for both kinds of material. This result is not explained by Charness (1976) model of expert performance and supports the idea that processes other than the identification or building of chunks might be at work in the encoding of the position.
