{"pk":33039,"title":"The ACT-R Theory and Visual Attention","subtitle":null,"abstract":"The ACT-R production-system theory (Anderson, 1993) has been extended to include a theory of visual attention and pattern recognition. Production rules can direct attention to primitive visual features in the visual array. \nWhen attention is focused on a region, features in that \nregion can be synthesized into declarative chunks. \nAssuming a time lo switch attention of about 200 msec, this \nmodel proves capable of simulating the results from a \nnumber of the basic studies of visual attention. W e have \nextended this model to complex problem-solving like \nequation solving where we have shown that an important \ncomponent of learning is acquiring more efficient strategies \nfor scanning the problem.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"17","is_remote":true,"remote_url":"https://escholarship.org/uc/item/6rv175qj","frozenauthors":[{"first_name":"John","middle_name":"R.","last_name":"Anderson","name_suffix":"","institution":"Carnegie Mellon University","department":""},{"first_name":"Michael","middle_name":"","last_name":"Matessa","name_suffix":"","institution":"Carnegie Mellon University","department":""},{"first_name":"Scott","middle_name":"","last_name":"Douglass","name_suffix":"","institution":"Carnegie Mellon University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"1995-01-02T02:00:00+08:00","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/33039/galley/24101/download/"}]}
