This capacity critically depends on use of the dual-structured linguistic system, in which meaningful words are represented by combinations of meaningless letters. Here we search for the evolutionary origin of this capacity in primates by designing dual-structured bigram symbol systems where different combinations of meaningless elements represent different objects. Initially, we trained Japanese macaques (Macaca fuscata) in an object-bigram symbolization task and in a visually-guided bigram construction task. Subsequently, we conducted a probe test using a symbolic bigram construction task. From the initial trial of the probe test, the Japanese macaques could sequentially choose the two elements of a bigram that was not actually seen but signified by a visually presented object. Moreover, the animals\u0027 spontaneous choice order bias, developed through the visually-guided bigram construction learning, was immediately generalized to the symbolic bigram construction test. Learning of dual-structured symbols by the macaques possibly indicates pre-linguistic adaptations for the ability of mentally constructing symbols in the common ancestors of humans and Old World monkeys.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_6_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "Scientific Reports. 2022, 12, 3566.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_6_description_53": {"attribute_name": "学位記番号", "attribute_value_mlt": [{"subitem_description": "新大院博(医)第1089号", "subitem_description_language": "ja", "subitem_description_type": "Other"}]}, "item_6_dissertation_number_52": {"attribute_name": "学位授与番号", "attribute_value_mlt": [{"subitem_dissertationnumber": "甲第5076号"}]}, "item_6_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1038/s41598-022-07563-z", "subitem_relation_type_select": "DOI"}}]}, "item_6_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "© The Author(s) 2022", "subitem_rights_language": "en"}, {"subitem_rights": "Creative Commons Attribution 4.0 International", "subitem_rights_language": "en", "subitem_rights_resource": "https://creativecommons.org/licenses/by/4.0/"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Liu, Nanxi", "creatorNameLang": "en"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2023-04-27"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "r4nmk1089.pdf", "filesize": [{"value": "1.81MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": "1.81MB", "url": {"label": "本文", "objectType": "fulltext", "url": "https://niigata-u.repo.nii.ac.jp/record/2000968/files/r4nmk1089.pdf"}, "version_id": "b06a8ccc-572b-4a39-9bbe-034e98831bc3"}, {"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2023-04-27"}], "displaytype": "detail", "download_preview_message": "", "file_order": 1, "filename": "r4nmk1089_a.pdf", "filesize": [{"value": "436KB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": "436KB", "url": {"label": "要旨", "objectType": "abstract", "url": "https://niigata-u.repo.nii.ac.jp/record/2000968/files/r4nmk1089_a.pdf"}, "version_id": "f8c69f07-698b-453b-9471-8e2004ea238e"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "doctoral thesis", "resourceuri": "http://purl.org/coar/resource_type/c_db06"}]}, "item_title": "Mental construction of object symbols from meaningless elements by Japanese macaques (Macaca fuscata)", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Mental construction of object symbols from meaningless elements by Japanese macaques (Macaca fuscata)", "subitem_title_language": "en"}, {"subitem_title": "無意味な要素から物を表す記号を組み立てるマカクザルの能力", "subitem_title_language": "ja"}]}, "item_type_id": "6", "owner": "1", "path": ["455", "562"], "permalink_uri": "http://hdl.handle.net/10191/0002000968", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-04-27"}, "publish_date": "2023-04-27", "publish_status": "0", "recid": "2000968", "relation": {}, "relation_version_is_last": true, "title": ["Mental construction of object symbols from meaningless elements by Japanese macaques (Macaca fuscata)"], "weko_shared_id": -1}
