Previous research indicates that individuals with congenital prosopagnosia (CP) fail to demonstrate significant priming from faces to related names in covert recognition tasks. The interpretation has been that CP precludes the ability to acquire face representations. In the current study we replicated this important finding. In addition, we also demonstrated significant 'true face effect' in a CP patient, where face primes that matched the probe names facilitated reaction times compared to unrelated face primes. These data suggest that some individuals with CP may possess degraded face representations that facilitate the priming of a person's identity, but not semantic associates.
先前的研究表明,患有先天性面孔失认症(CP)的个体在隐蔽识别任务中,无法从面孔到相关名字表现出显著的启动效应。对此的解释是,先天性面孔失认症妨碍了获取面孔表征的能力。在当前研究中,我们重复了这一重要发现。此外,我们还在一名先天性面孔失认症患者身上证明了显著的“真实面孔效应”,即与探测名字匹配的面孔启动刺激相比不相关的面孔启动刺激,能加快反应时间。这些数据表明,一些患有先天性面孔失认症的个体可能拥有退化的面孔表征,这种表征有助于启动对一个人身份的识别,但无助于启动语义联想。
