(in press).<br \/>\nNeuroscience Letters<\/p>\n<p>Conflicts with others about decisions are reflected in the medial frontal negativity (MFN),\u3000which is a component of the event-related brain potential (ERP). The present study examined how\u3000decision confidence in a perceptual decision task modulated the ERP components elicited by\u3000decision conflicts with others. In a motion discrimination task, participants were randomly assigned\u3000to an easy or a difficult group that differed in coherence levels of the moving dots. Participants were\u3000paired with a confederate and presented the confederate\u2019s decision about the motion direction of the\u3000moving dots, which was either congruent or incongruent with the participants\u2019 decision. MFN was\u3000elicited by the incongruent confederate\u2019s decision and its amplitude did not differ between groups. A\u3000larger P300 amplitude was elicited by incongruent decisions in the easy group, whereas the P300\u3000amplitude did not differ between congruent and incongruent decisions in the difficult group. These\u3000results indicate the functional dissociation between MFN and P300 in the evaluation of social\u3000feedback. It is suggested that MFN might reflect automatic detection of conflicts about decisions,whereas the P300 might detect the deviation from internal expectations regarding other\u2019s decisions.<\/p>\n<p>\u8fd1\u5e74\uff0c\u500b\u4eba\u306e\u610f\u898b\u3068\u96c6\u56e3\u306e\u610f\u898b\u3068\u306e\u4e0d\u4e00\u81f4\u304c\u751f\u3058\u305f\u3068\u304d\u306b\u306f\uff0c\u5931\u6557\u884c\u52d5\u306e\u51e6\u7406\u3084\u30a8\u30e9\u30fc\u691c\u51fa\u3092\u53cd\u6620\u3059\u308b\u4e8b\u8c61\u95a2\u9023\u8133\u96fb\u4f4d\uff08ERP\uff09\u3067\u3042\u308b\u5185\u5074\u524d\u982d\u9670\u6027\u96fb\u4f4d\uff08Medial Frontal Negativity\uff1aMFN\uff09\u304a\u3088\u3073\u6ce8\u610f\u306e\u914d\u5206\u3092\u53cd\u6620\u3059\u308bP300\u304c\u751f\u8d77\u3059\u308b\u3053\u3068\u304c\u5831\u544a\u3055\u308c\u3066\u3044\u308b\u3002\u672c\u7814\u7a76\u3067\u306f\uff0c\u5bfe\u4eba\u72b6\u6cc1\u306b\u304a\u3044\u3066\u77e5\u899a\u7684\u610f\u601d\u6c7a\u5b9a\u3092\u884c\u3046\u8ab2\u984c\u3092\u7528\u3044\u308b\u3053\u3068\u3067\uff0c\u5bfe\u4eba\u845b\u85e4\u3092\u751f\u8d77\u3059\u308b\u3068\u3068\u3082\u306b\u5b9f\u9a13\u7684\u306b\u5224\u65ad\u306e\u78ba\u4fe1\u5ea6\u3092\u64cd\u4f5c\u3057\uff0c\u78ba\u4fe1\u5ea6\u304c\u5bfe\u4eba\u845b\u85e4\u306e\u51e6\u7406\u306b\u53ca\u307c\u3059\u5f71\u97ff\u3092\u660e\u3089\u304b\u306b\u3059\u308b\u3053\u3068\u3092\u76ee\u7684\u3068\u3057\u305f\u3002\u96e3\u6613\u5ea6\u9ad8\u7fa4\u3082\u3057\u304f\u306f\u4f4e\u7fa4\u306b\u30e9\u30f3\u30c0\u30e0\u306b\u5272\u308a\u5f53\u3066\u3089\u308c\u305f\u7537\u5b50\u5927\u5b66\u751f26\u540d\u304c\u4ed6\u8005\uff08\u30b5\u30af\u30e9\uff09\u3068\u30da\u30a2\u3092\u7d44\u307f\u3001\u30e9\u30f3\u30c0\u30e0\u30c9\u30c3\u30c8\u523a\u6fc0\u306e\u904b\u52d5\u65b9\u5411\u3092\u5224\u65ad\u3059\u308b\u77e5\u899a\u7684\u610f\u601d\u6c7a\u5b9a\u8ab2\u984c\u3092\u884c\u3063\u305f\u3002\u4e21\u8005\u306e\u6b63\u7b54\u6570\u306e\u5408\u7b97\u304c\u5b9f\u9a13\u5f8c\u306b\u4e0e\u3048\u3089\u308c\u308b\u91d1\u92ad\u5831\u916c\u306b\u306a\u308b\u305f\u3081\u3001\u3067\u304d\u308b\u9650\u308a\u6b63\u78ba\u306b\u8ab2\u984c\u3092\u9042\u884c\u3059\u308b\u3088\u3046\u306b\u6559\u793a\u3055\u308c\u305f\u3002\u4ed6\u8005\u306e\u5224\u65ad\u306f\uff0c\u53c2\u52a0\u8005\u306e\u53cd\u5fdc\u306b\u95a2\u308f\u3089\u305a\u7b49\u983b\u5ea6\u3067\u4e00\u81f4\u3042\u308b\u3044\u306f\u4e0d\u4e00\u81f4\u3059\u308b\u3088\u3046\u64cd\u4f5c\u3057\u305f\u3002\u4ed6\u8005\u306e\u5224\u65ad\u304c\u63d0\u793a\u3055\u308c\u305f\u6642\u70b9\u3092\u523a\u6fc0\u30aa\u30f3\u30bb\u30c3\u30c8\u3068\u3057\u3066\u7b97\u51fa\u3057\u305fERP\u3092\u5bfe\u8c61\u306b\u5206\u6790\u3092\u884c\u3063\u305f\u7d50\u679c\u3001\u4e21\u7fa4\u306b\u304a\u3044\u3066MFN\u304c\u89b3\u5bdf\u3055\u308c\uff0c\u5bfe\u4eba\u845b\u85e4\u304c\u5931\u6557\u3084\u30a8\u30e9\u30fc\u3068\u3057\u3066\u51e6\u7406\u3055\u308c\u308b\u3053\u3068\u304c\u793a\u3055\u308c\u305f\u3002\u307e\u305f\uff0c\u5224\u65ad\u306e\u78ba\u4fe1\u5ea6\u306fMFN\u306b\u5f71\u97ff\u3057\u3066\u304a\u3089\u305a\uff0c\u5bfe\u4eba\u845b\u85e4\u306e\u51e6\u7406\u306f\u81ea\u52d5\u7684\u3067\u3042\u308b\u3053\u3068\u304c\u793a\u5506\u3055\u308c\u305f\u3002\u6700\u5f8c\u306b\uff0c\u96e3\u6613\u5ea6\u4f4e\u7fa4\u306eP300\u306b\u304a\u3044\u3066\u306e\u307f\u4e00\u81f4\u6761\u4ef6\u3068\u4e0d\u4e00\u81f4\u6761\u4ef6\u306b\u6761\u4ef6\u5dee\u304c\u89b3\u5bdf\u3055\u308c\u305f\u3053\u3068\u304b\u3089\uff0c\u5224\u65ad\u306e\u78ba\u4fe1\u5ea6\u306f\uff0c\u5bfe\u4eba\u845b\u85e4\u304c\u81ea\u52d5\u7684\u306b\u691c\u51fa\u3055\u308c\u305f\u5f8c\u306e\u51e6\u7406\u6bb5\u968e\u3092\u8abf\u6574\u3059\u308b\u3053\u3068\u304c\u660e\u3089\u304b\u306b\u306a\u3063\u305f\u3002<\/p>\n<!-- google_ad_section_end -->\n<div class='wp_social_bookmarking_light'>        <div class=\"wsbl_google_plus_one\"><g:plusone size=\"medium\" annotation=\"none\" href=\"https:\/\/www.psylabo.com\/?p=11254\" ><\/g:plusone><\/div>        <div class=\"wsbl_facebook_like\"><div id=\"fb-root\"><\/div><fb:like href=\"https:\/\/www.psylabo.com\/?p=11254\" layout=\"button\" action=\"like\" width=\"100\" share=\"false\" show_faces=\"false\" ><\/fb:like><\/div>        <div class=\"wsbl_twitter\"><a href=\"https:\/\/twitter.com\/share\" class=\"twitter-share-button\" data-url=\"https:\/\/www.psylabo.com\/?p=11254\" data-text=\"\u3010\u793e\u4f1a\u5fc3\u7406\u3011\u56fd\u969b\u8a8c\u63b2\u8f09\u8ad6\u6587\" data-via=\"@psychologylabo\" data-lang=\"en\">Tweet<\/a><\/div><\/div>\n<br class='wp_social_bookmarking_light_clear' \/>\n","protected":false},"excerpt":{"rendered":"<!-- google_ad_section_start -->\nEffect of Decision Confidence on the Evaluation of Conflicting Decisions in a Social Context.
