{"pk":29119,"title":"HOT: Higher Order Tetris, Experts’ Subgoals and Activities","subtitle":null,"abstract":"For Tetris, clearing 4 lines at once (a ”Tetris”) results in 7.5 times as many points as clearing one line four times. Gettinga Tetris requires a solid block of filled cells, 9 columns wide and 4 rows high. That block leaves vacant one column. If anI-beam appears, all 4 rows can be cleared. Finalists at the Classic Tetris World Championships have an explicit subgoalstructure not seen in lesser players. Among the 32 competitors, the 4 finalists are those who are most adept at maintainingor preparing the board for a Tetris by executing one of these subgoals, as needed. We present a video-based analysis whichcompares the proportion of time spent on each activity between those eliminated on the first tournament round and thosewho survive to the final round.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Member Abstracts","is_remote":true,"remote_url":"https://escholarship.org/uc/item/4xq027fh","frozenauthors":[{"first_name":"Jacquelyn","middle_name":"","last_name":"Berry","name_suffix":"","institution":"Rensselaer Polytechnic Institute","department":""},{"first_name":"Wayne","middle_name":"","last_name":"Gray","name_suffix":"","institution":"Rensselaer Polytechnic Institute","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2019-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/29119/galley/18990/download/"}]}
