{"pk":27393,"title":"Enforced pointing gesture can indicate invisible objects behind a wall","subtitle":null,"abstract":"The pointing gesture is regarded as indicating an object or\nlocation in the environment. People sometimes point to\ninvisible objects, but the inferential mechanism is not known.\nThis study examined comprehension of pointing with a bent\nindex finger at an invisible object behind a wall. The\nexperimenter pointed at an object using either typical pointing\nor “enforced pointing” behind a wall that was either opaque\nor transparent. In enforced pointing, the experimenter moved\nhis arm in an arc movement. The participants guessed which\nobject was being denoted. The wall was also either relatively\nhigh or relatively low. When the participants looked at typical\npointing, they thought that objects both in front of the wall\nand behind the wall were being denoted. However, when they\nlooked at enforced pointing, they more frequently thought that\nobjects behind the wall were denoted. People seemed to use\npragmatic knowledge on this “enforced” pointing gesture.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"gesture; declarative pointing; common ground;\nnon-linguistic information"}],"section":"Posters: Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/822221w9","frozenauthors":[{"first_name":"Hajime","middle_name":"","last_name":"Takahashi","name_suffix":"","institution":"Tokyo Denki University","department":""},{"first_name":"Tetsuya","middle_name":"","last_name":"Yasuda","name_suffix":"","institution":"Jumonji University","department":""},{"first_name":"Harumi","middle_name":"","last_name":"Kobayashi","name_suffix":"","institution":"Tokyo Denki University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2017-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/27393/galley/17029/download/"}]}
