【摘要】 自我面孔研究中,自我面孔加工显著快于其他面孔的现象被称作自我面孔优势效应。先前研究表明,自我面孔优势的产生源于对自我面孔的加工采用自我参照框架(王凌云,张明,隋洁.自我参照框架决定了自我面孔优势效应的出现.心理学报,2011.05.),本研究分别采用ERPs(实验1)和fMRI(实验2)技术探讨参照框架调控自我面孔优势的神经机制。实验中,被试被要求分别从观察者的角度(自我参照)和被观察的像的角度(他人参照)对自我、朋友或陌生人面孔进行朝向判断。结果发现:参照框架调控自我面孔优势发生在面孔结构编码之后的280-340ms,且主要发生在中央和右侧的额顶区域;自我参照下自我面孔与朋友面孔相比激活了双侧额下回、额上回,右侧额中回,右侧顶下叶,右侧楔前叶,右侧前扣带回和左侧脑岛等区域,而他人参照下自我面孔只激活了左侧脑岛;参照框架与自我面孔交互激活了右侧的额内回、前扣带回和小组齿状回以及左侧楔叶,这些区域可能反映了自我面孔优势的独特神经基础。更多还原

【Abstract】 Ones response to their own faces more fastly and accurately than those to the faces of others,which is called self-advantage effect in face recognition.Previous studies indicated that the self-reference frame is key to the occuring of self-face advantage effect (Wang Lingyun,Zhang Ming,Sui Jie.Self- face advantage benefits from a visual self-reference frame.Acta Psychologica Sinica, 2011.05),in this study ERPs(Exp.1) and fMRI(Exp.2) were used to explore the neural mechanism of self-advantage effect benefits from self-reference frame.The results showed,at the central and right frontal-parietal areas,the self-face advantage effect was modulated by judgment-reference frame in 280-340ms that was after the face structural encode;Compared with the familair face,activation selective to the self face was observed in the bilateral anterrior frontal gyrus and inferior frontal gyrus,the right middle frontal gyrus,inferior parietal lobule,precuneus,anterior cingulate gyrus,as well as left insula in self-reference frame condition,while only left insula in other-reference condition,the results indicate that self-reference frame plays a key role in self-face processing;Moreover,the interact contrast between judgment-reference frame and self-relevance showed the activation in the right medial frontal gyrus,anterior cingulate, sub-gyrus and left cuneus,of which regions may be involved in self-face advantage effect更多还原
