However, ethological studies reported state-dependent strategy-optimization irrespective of individual preference. To synthesize the two contrasting literatures, we developed a novel gambling task that dynamically manipulated the quota severity (required outcome to clear the task) in a course of choice trials and conducted a task-fMRI study in human participants. The participants showed their individual risk preference when they had no quota constraint (‘individual-preference mode’), while they adopted state-dependent optimal strategy when they needed to achieve a quota (‘strategy-optimization mode’). fMRI analyses illustrated that the interplay among prefrontal areas and salience-network areas reflected the quota severity and the utilization of the optimal strategy, shedding light on the neural substrates of the quota-dependent risk attitude. Our results demonstrated the complex nature of risk-sensitive decision-making and may provide a new perspective for the understanding of problematic risky behaviors in human.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"ELSEVIER"}]},"item_8_relation_13":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"27343698","subitem_relation_type_select":"PMID"}}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.neuroimage.2016.06.040","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.sciencedirect.com/science/article/pii/S1053811916302890"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.sciencedirect.com/science/article/pii/S1053811916302890","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1053-8119","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Fujimoto, Atsushi"}],"nameIdentifiers":[{"nameIdentifier":"479229","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takahashi, Hidehiko"}],"nameIdentifiers":[{"nameIdentifier":"479230","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"藤本 淳","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"479231","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高橋 英彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"479232","nameIdentifierScheme":"WEKO"}]}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Flexible Modulation of Risk Attitude during Decision-Making under Quota","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Flexible Modulation of Risk Attitude during Decision-Making under Quota"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-04-25"},"publish_date":"2017-04-25","publish_status":"0","recid":"47758","relation_version_is_last":true,"title":["Flexible Modulation of Risk Attitude during Decision-Making under Quota"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:35:52.995964+00:00"}
