The mind’s eye in blindfold chess
نویسندگان
چکیده
Visual imagery plays an important role in problem solving, and research into blindfold chess has provided a wealth of empirical data on this question. We show how a recent theory of expert memory (the template theory, Gobet & Simon, 1996, 2000) accounts for most of these data. However, how the mind’s eye filters out relevant from irrelevant information is still underspecified in the theory. We describe two experiments addressing this question, in which chess games are presented visually, move by move, on a board that contains irrelevant information (static positions, semi-static positions, and positions changing every move). The results show that irrelevant information affects chess masters only when it changes during the presentation of the target game. This suggests that novelty information is used by the mind’s eye to select incoming visual information and separate “figure” and “ground.” Mechanisms already present in the template theory can be used to account for this novelty effect.

Visualization, pattern recognition, and forward search: effects of playing speed and sight of the position on grandmaster chess errors
A new approach examined two aspects of chess skill, long a popular topic in cognitive science. A powerful computer-chess program calculated the number and magnitude of blunders made by the same 23 grandmasters in hundreds of serious games of slow (“classical”) chess, regular “rapid” chess, and rapid “blindfold” chess, in which opponents transmit moves without ever seeing the actual position. Ra...
متن کاملComputational Modelling of Mental Imagery in Chess: A Sensitivity Analysis
An important aim of cognitive science is to build computational models that account for a large number of phenomena but have few free parameters, and to obtain more veridical values for the models’ parameters by successive approximations. A good example of this approach is the CHREST model (Gobet & Simon, 2000), which has simulated numerous phenomena on chess expertise and in other domains. In ...
متن کاملA pattern-recognition theory of search in expert problem solving
Understanding how look-ahead search and pattern recognition interact is one of the important research questions in the study of expert problem-solving. This paper examines the implications of the template theory (Gobet & Simon, 1996a), a recent theory of expert memory, on the theory of problem solving in chess. Templates are “chunks” (Chase & Simon, 1973) that have evolved into more complex dat...
متن کاملAuditory memory function in expert chess players
Background: Chess is a game that involves many aspects of high level cognition such as memory, attention, focus and problem solving. Long term practice of chess can improve cognition performances and behavioral skills. Auditory memory, as a kind of memory, can be influenced by strengthening processes following long term chess playing like other behavioral skills because of common processing pat...
