In 1937 he became chess champion of Amsterdam, and in 1939 he was part of the chess team that represented the Netherlands at the Olympiad in Buenos Aires. * Promotion on "The thinking of the chess player" : In 1946, De Groot obtained his doctorate cum laude in Mathematics and Physics with his thesis ""Het denken van den schaker"". This work, later published in English under the title "Thought and choice in chess", would bring him world fame, partly due to the enthusiastic reception of the later Nobel Prize winner Herbert Simon, who learned Dutch especially for this. De Groot obtained his doctorate under Prof. Dr. Géza Révész and was also assisted by Dutch masters such as Max Euwe, Hans Kmoch and Nicolaas Cortlever. His dissertation was inspired by the work of the thinking psychologist Otto Selz and examined the thought processes that occur in chess, including Max Euwe. He examined the memory of chess grandmasters and average club chess players, using only a chessboard and chess clock. In an experiment he put a common chess position on the board and had both players view it for five seconds, after which both had to reconstruct the position. He did the same with a position where the pieces were placed randomly on the board. The grandmasters reconstructed the chess position much better, but the random position with the same margin of error as the club chess players. From similar experiments, De Groot concluded that the cognitive skills of the grandmasters mainly consisted of their ability to comprehend chess positions better as an organized whole than as a collection of individual chess pieces. De Groot's dissertation is said to have formed the basis of the so-called cognitive revolution in psychology in the United States. (Sources : Wikipedia) Verzending: goed verpakt/verzekerd.
