The current study examined perceptual differences between adults and youth in perceiving ambiguous facial expressions. We estimated individuals' internal representation for facial expressions and compared it between age groups (adolescents: N = 108, Mage = 13.04 years, 43.52% female; adults: N = 81, Mage = 31.54, 65.43% female). We found that adolescents' perceptual representation for facial emotion is broader than that of adults', such that adolescents experience more difficulty in identifying subtle configurational differences of facial expressions. At the neural level, perceptual uncertainty in face-selective regions (e.g., fusiform face area, occipital face area) were significantly higher for adolescents than for adults, suggesting that adolescents' brains more similarly represent lower intensity emotional faces than do adults'. Our results provide evidence for age-related differences concerning psychophysical differences in perceptual representation of emotional faces at the neural and behavioral level.

本研究考察了成人和青少年在感知模糊面部表情时的知觉差异。我们估计了个体对面部表情的内部表现，并在年龄组之间进行了比较（青少年：N = 108，Mage = 13.04 岁，43.52%女性；成年人：N = 81，Mage = 31.54，65.43%女性）。我们发现，青少年对面部表情的感知表现比成年人更广泛，因此青少年在识别面部表情细微的结构差异方面更困难。在神经水平上，面部选择区域（例如梭状回面部区、枕叶面部区）的感知不确定性在青少年中显著高于成年人，这表明青少年的大脑更相似地代表了比成年人更低强度的情绪面孔。我们的研究结果为神经和行为水平上情绪面孔知觉表现的心理物理差异的年龄相关差异提供了证据。
