摘　　要：发展性面孔失认症一直受到学界广泛关注,但是关于其典型的面孔识别缺陷源于面孔识别过程中哪一认知阶段的问题,尚不明确。很多研究表明先天性面孔失认症患者在记忆维持和检索阶段上具有缺陷表现,但是该记忆阶段的缺陷表现很可能来源于更为早期的感知编码损伤——“由粗到精”整体加工上的不足,在神经机制上表现为梭状回面孔区、枕叶面孔区的面孔选择性反应减弱,以及这两个脑区之间连接减弱。此外,其中精细而非粗糙的整体面孔感知编码问题与先天性面孔失认症患者面孔识别的行为缺陷具有更加紧密的关系。Developmental prosopagnosia (DP) has been widely concerned by the academic community, but it is still unclear which cognitive stage of the process is the cause of its typical face recognition deficit. Many studies suggested that the DPs have defective performance in the memory maintenance and retrieval stage, but the defective performance in this memory stage is likely to be derived from the earlier perceptual coding impairment, especially the insufficiency in coarse-to-fine holistic process, which is manifested in the weakened selective response of the fusiform face area and occipital face area, as well as the weakened connection between these two regions. In addition, the fine rather than rough face perception ability is more related to the face recognition deficit in DPs.
