--- abstract: 'In this paper I will present a detailed ACT-R model of how the task-specific knowledge for a new, complex task is learned. The model is capable of acquiring its knowledge through experience, using a declarative representation that is gradually compiled into a procedural representation. The model exhibits several characteristics that concur with Fitt�s theory of skill learning, and can be used to show that individual differences in working memory capacity initially have a large impact on performance, but that this impact diminished after sufficient experience. Some preliminary experimental data support these findings.' altloc: - http://tcw2.ppsw.rug.nl/prepublications/prepubsTCW-99-4.pdf chapter: ~ commentary: ~ commref: ~ confdates: August 19-21 conference: 21th annual conference of the cognitive science society confloc: 'Vancouver, Canada' contact_email: ~ creators_id: [] creators_name: - family: Taatgen given: Niels A. honourific: '' lineage: '' date: 1999 date_type: published datestamp: 1999-02-19 department: ~ dir: disk0/00/00/07/99 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: [] eprint_status: archive eprintid: 799 fileinfo: /style/images/fileicons/application_pdf.png;/799/3/prepubsTCW%2D99%2D4.pdf full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: unpub issn: ~ item_issues_comment: [] item_issues_count: 0 item_issues_description: [] item_issues_id: [] item_issues_reported_by: [] item_issues_resolved_by: [] item_issues_status: [] item_issues_timestamp: [] item_issues_type: [] keywords: 'cognitive modelling, cognitive modeling, ACT-R, skill learning, scheduling, working memory, working memory capacity, individual differences, procedural memory' lastmod: 2011-03-11 08:54:17 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: ~ pagerange: ~ pubdom: FALSE publication: ~ publisher: ~ refereed: FALSE referencetext: ~ relation_type: [] relation_uri: [] reportno: ~ rev_number: 12 series: ~ source: ~ status_changed: 2007-09-12 16:34:30 subjects: - cog-psy - comp-sci-art-intel - comp-sci-mach-learn succeeds: ~ suggestions: ~ sword_depositor: ~ sword_slug: ~ thesistype: ~ title: A model of learning task-specific knowledge for a new task type: confpaper userid: 398 volume: ~
