In this study we used two secondary tasks of differing cognitive degrees of difficulty for dual tasking and examined their influences on the P300 components of the primary task. We used Oddball task as the primary task and Kana search task and Writing task as the secondary tasks. Amplitude of P300 obtained from the primary task decreased and the latency extended with the more difficult secondary Kana search test. No significant difference was noticed with the less difficult secondary Writing test. We believe that a competition of mental resources resulted from the dual task with Kana search. We feel that degrees in cognitive loading influenced the P300 of the primary task, because of the necessity of mental resource allocation.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"長崎大学医学部保健学科紀要 = Bulletin of Nagasaki University School of Health Sciences. 2004, 17(1), p.25-29","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"78202","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Tabira, Takayuki"}]},{"nameIdentifiers":[{"nameIdentifier":"78203","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nara, Nobuhiro"}]}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11595980","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09160841","subitem_source_identifier_type":"ISSN"}]},"item_3_text_62":{"attribute_name":"sortkey","attribute_value_mlt":[{"subitem_text_value":"P00025-P00029"}]},"item_3_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"田平, 隆行"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"奈良, 進弘"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-23"}],"displaytype":"detail","filename":"igaku17_01_05_t.pdf","filesize":[{"value":"663.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"igaku17_01_05_t.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/19044/files/igaku17_01_05_t.pdf"},"version_id":"4941bd9b-d1b9-4585-8ed8-5048d3dbdeb3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"認知的作業負荷量","subitem_subject_scheme":"Other"},{"subitem_subject":"P300","subitem_subject_scheme":"Other"},{"subitem_subject":"二重課題","subitem_subject_scheme":"Other"},{"subitem_subject":"cognitive workload","subitem_subject_scheme":"Other"},{"subitem_subject":"P300","subitem_subject_scheme":"Other"},{"subitem_subject":"dual task","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"認知的作業負荷量の相違が事象関連電位に及ぼす影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"認知的作業負荷量の相違が事象関連電位に及ぼす影響"}]},"item_type_id":"3","owner":"2","path":["1345"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-07-01"},"publish_date":"2008-07-01","publish_status":"0","recid":"19044","relation_version_is_last":true,"title":["認知的作業負荷量の相違が事象関連電位に及ぼす影響"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T03:33:49.226468+00:00"}
