--- abstract: 'Computational simulations are used to model the following: (1) category learning through sensorimotor trial and error ("sensorimotor toil") and how it generates categorical perception (decreased between-category similarity and increased within-category similarity); (2) symbol grounding (the connection between symbols and the sensorimotor categories that they name); (3) the origins of language as the capacity to acquire categories indirectly, by definition alone ("symbolic theft"); and (4) the evolutionary advantage of acquiring categories by this symbolic theft instead of sensorimotor toil.' altloc: - http://www.cogsci.soton.ac.uk/~harnad/Papers/Harnad/harnad01.cangelosi-greco.pdf chapter: ~ commentary: ~ commref: ~ confdates: ~ conference: ~ confloc: ~ contact_email: ~ creators_id: [] creators_name: - family: Cangelosi given: Angelo honourific: '' lineage: '' - family: Greco given: Alberto honourific: '' lineage: '' - family: Harnad given: Stevan honourific: '' lineage: '' date: 2002 date_type: published datestamp: 2002-03-12 department: ~ dir: disk0/00/00/21/32 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: - family: Cangelosi given: A honourific: '' lineage: '' - family: Parisi given: D honourific: '' lineage: '' eprint_status: archive eprintid: 2132 fileinfo: /style/images/fileicons/application_pdf.png;/2132/3/harnad01.cangelosi%2Dgreco.pdf full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: pub 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: 'perceptual learning, symbol grounding, categorical perception, categorization, evolution of language, neural nets' lastmod: 2011-03-11 08:54:54 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: ~ pagerange: ~ pubdom: FALSE publication: Simulating the Evolution of Language publisher: 'Springer, London' refereed: FALSE referencetext: |+ Andrews J, Livingston K, Harnad S (1998) Categorical perception effects induced by category learning.
