TL;DR: This article developed a technique for isolating and studying the perceptual structures that chess players perceive and analyzed the size and nature of these structures as a function of chess skill, and used the successive glances at the position in the perceptual task and long pauses in the memory task to segment the structures in the reconstruction protocol.
TL;DR: In this paper, the authors present a theoretical formulation to characterize how expert chess players perceive the chess board and describe some tasks that correlate with chess skill and the cognitive processes of skilled chess players.
Abstract: Publisher Summary This chapter describes the progress made toward understanding chess skill. It describes the work on perception in chess, adding some new analyses of the data. It presents a theoretical formulation to characterize how expert chess players perceive the chess board. It describes some tasks that correlate with chess skill and the cognitive processes of skilled chess players. It is believed that the demonstration of de Groot's, far from being an incidental side effect of chess skill, actually reveals one of the most important processes that underlie chess skill—the ability to perceive familiar patterns of pieces. In the first experiment discussed in the chapter, two tasks were used. The memory task was very similar to de Groot's task: chess players saw a position for 5 seconds and then attempted to recall it. Unlike de Groot, multiple trials were used—5 seconds of viewing followed by recall—until the position was recalled perfectly. The second task or the perception task for simplicity involved showing chess players a position in plain view.
TL;DR: This work focuses on recent successes in verbal learning, expert memory, language acquisition and learning multiple representations, to illustrate the implementation and use of chunking mechanisms within contemporary models of human learning.
TL;DR: It is suggested that chess players, like experts in other recall tasks, use long-term memory retrieval structures (Chase & Ericsson, 1982) or templates in addition to chunks in short- term memory to store information rapidly.
TL;DR: The behavior of CHREST, a computer implementation of the template theory, in a memory task when the presentation time is varied from one second to sixty, on the recall of game and random positions is described, and the model is compared to human data.
