People are better at recognizing familiar versus unfamiliar faces. The current study investigated whether familiarity would lead to a larger face individuation response as measured via fast periodic visual stimulation (FPVS). While electroencephalography (EEG) was recorded, participants viewed oddball sequences of faces made up of more versus less familiarized faces. In each sequence, a single base face was repeated at a rate of 6 Hz and oddball faces with different identities were presented every fifth face (6 Hz/5 = 1.2 Hz). As in previous studies, significant face individuation responses were observed at 1.2 Hz and its harmonics, with the strongest responses located over right occipito-temporal electrode sites. Despite a relatively minimal learning manipulation, the face individuation response over right occipito-temporal sites was stronger for more versus less familiarized faces. These results suggest that the fast-periodic visual oddball paradigm offers a promising means for investigating face learning.
人们更擅长识别熟悉的面孔和陌生的面孔。本研究通过快速周期性视觉刺激（FPVS）来探究熟悉度是否会导致更大的面孔个体化反应。在记录脑电图（EEG）的同时，参与者观看了由更多熟悉面孔和更少熟悉面孔组成的奇特面孔序列。在每个序列中，一个基础面孔以 6 Hz 的频率重复，而不同身份的奇特面孔每第五个面孔出现一次（6 Hz/5 = 1.2 Hz）。与之前的研究一样，在 1.2 Hz 及其谐波处观察到了显著的面孔个体化反应，最强的反应位于右侧枕颞电极部位。尽管进行了相对较少的学习操作，但在右侧枕颞部位的面孔个体化反应对于更多熟悉的面孔要强于更少熟悉的面孔。这些结果表明，快速周期性视觉奇特范式为研究面孔学习提供了一种很有前途的手段。
