--- abstract: "Skoyles's case against human brain size being related to IQ is strong; but his case in favor of its being related to expertise is weak. I propose that the explanation for the evolutionary expansion of the human brain in fact lies far away, in the need to have a brain that could continue to function into old age." altloc: - http://psycprints.ecs.soton.ac.uk/archive/00000659/02/psyc.99.10.024.brain-expertise.4.humphrey chapter: ~ commentary: ~ commref: http://psycprints.ecs.soton.ac.uk/archive/00000056/ confdates: ~ conference: ~ confloc: ~ contact_email: ~ creators_id: [] creators_name: - family: Humphrey given: Nicholas honourific: '' lineage: '' date: 1999 date_type: published datestamp: 2002-08-12 department: ~ dir: disk0/00/00/08/48 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: [] eprint_status: archive eprintid: 848 fileinfo: /style/images/fileicons/text_html.png;/848/1/skoyles.htm 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: 'brain size, evolution of intelligence, human life history, social intelligence hypothesis, human evolution' lastmod: 2011-03-11 08:54:20 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: 024 pagerange: 1-3 pubdom: FALSE publication: Psycoloquy publisher: ~ refereed: TRUE referencetext: ~ relation_type: [] relation_uri: [] reportno: ~ rev_number: 8 series: ~ source: ~ status_changed: 2007-09-12 16:35:03 subjects: - bio-ani-cog - physio-psy - Psycoloquy - bio-socio - evol-psy - behav-neuro-sci succeeds: ~ suggestions: ~ sword_depositor: ~ sword_slug: ~ thesistype: ~ title: Why Grandmothers May Need Large Brains.
