Abstract: The ability of perceptual search was studied by visualizing moves ona stationary chessboard presented on a video monitor. The subjects were40 students from an Engineering professional school who had previous ex-periences in the game of Solitaire. Instead of actually moving a particularchesspiece, the subjects were asked to imagine the moves of the chesspie-ces on the chessboard. The results showed, if the initial state and goalstate of the problem were presented, the subjects could accomplish 12 stepsof anticipatory moves through perceptual search (average correct res-ponse rate was more than 60%); reaction time increased with the increaseof steps of anticipatory moves.
