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.

熟悉增加了通过快速周期性视觉刺激测量的面部个性化

人们更擅长识别熟悉的面孔和陌生的面孔。目前的研究调查了通过快速周期性视觉刺激 (FPVS) 测量的熟悉度是否会导致更大的面部个性化反应。在记录脑电图 (EEG) 的同时，参与者看到了由更多与不太熟悉的面孔组成的奇怪面孔序列。在每个序列中，一个基本面以 6 Hz 的速率重复，每五个面（6 Hz/5 = 1.2 Hz）出现一个具有不同身份的奇怪面孔。与之前的研究一样，在 1.2 Hz 及其谐波处观察到显着的面部个性化响应，最强响应位于右侧枕颞电极部位。尽管学习操作相对较少，与不太熟悉的面孔相比，右侧枕颞部位的面孔个性化反应更强。这些结果表明，快速周期视觉古怪范式为研究人脸学习提供了一种很有前途的方法。
