Abstract: | Previous research has found that the ability to recall briefly presented chess positions varies with playing strength, except when random positions are used. The suggestion therefore arises that mastery consists of recognizing configurations that are associated with plausible moves. This approach is tested by comparing the memory scores and move-choice protocols of players in six skill categories, using random chess positions. Contrary to any strong form of recognition-association hypothesis, differences in chess skill are shown to persist although memory differences are abolished. It is further shown that the moves selected are not based on those few pieces that are remembered. Skill-related differences in the accuracy of positional evaluations also occur, but they are less marked than in earlier results. An alternative approach to chess skill seems appropriate, in which memory effects may function at the evaluation phase. |
