目前的研究调查了出生体重对成年后面部表情识别能力的影响，这些人是已知的前瞻性跟踪时间最长的极低出生体重幸存者(ELBW；<；1000 g)。我们通过测量知觉阈值来检测不同情绪类别之间的微妙表情和混淆，从而将视觉知觉能力从情绪加工中分离出来。极低出生体重成人(N= ，MAGE= 31.9岁)比正常出生体重对照组(N= 82，MAGE= 32.5岁)更容易从愤怒的脸上看到恐惧。这一发现并不是ELBW成年人处理恐惧表情的感知效率提高的结果，因为两组人在低强度面部表情中检测情绪的阈值没有差异。这些发现表明，对恐惧的加工偏向可能反映了从出生于ELBW起的长期发展影响，这可能预示着ELBW幸存者的社会情感问题。
The current study investigated the impact of birth weight on the ability to recognize facial expressions in adulthood among the longest known prospectively followed cohort of extremely low birth weight survivors (ELBW; <1,000 g). We measured perceptual threshold to detect subtle facial expressions and confusion among different emotion categories in order to disentangle visual perceptual ability from emotional processing. ELBW adults (N= 64,Mage= 31.9 years) were more likely than normal birth weight (NBW) controls (N= 82,Mage= 32.5 years) to see fear in angry faces. This finding was not a result of increased perceptual efficiency in processing fearful expressions in the ELBW adults, since the two groups did not differ on their threshold to detect emotion in low intensity facial expressions. These findings suggest that a processing bias toward fear may reflect long‐term developmental effects from being born at ELBW that may portend socioemotional problems that characterize ELBW survivors.
