ABSTRACT Slow maturation of visual pathways transmitting low spatial frequency (LSF) information may contribute to inaccurate facial emotion recognition in adolescence. We recorded ERPs from adolescents and adults to upright and inverted happy faces, fearful faces, and chairs, which were unfiltered, contained only LSFs, or only high spatial frequencies. P100s and N170s were larger for adolescents than adults, with the greatest effect size for LSF stimuli. For LSFs only, adolescents showed a larger N170 inversion effect for happy than for fearful faces, but adults showed the opposite response. Thus, immaturities in LSF pathways appear to impact facial expression processing in adolescents.

青少年的低空间频率敏感性和情绪面部处理：一项与事件相关的潜在研究

摘要 传输低空间频率 (LSF) 信息的视觉通路的缓慢成熟可能导致青春期面部情绪识别不准确。我们记录了从青少年和成人到直立和倒立的快乐面孔、恐惧面孔和椅子的 ERP，这些面孔未经过滤，仅包含 LSF，或仅包含高空间频率。青少年的 P100 和 N170 比成人大，LSF 刺激的影响最大。仅对于 LSF，青少年对快乐的 N170 倒置效应比对恐惧的面孔更大，但成年人则表现出相反的反应。因此，LSF 通路的不成熟似乎会影响青少年的面部表情处理。
