背景
早产与儿童时期的神经认知障碍密切相关，包括增加社交困难的风险。眼球跟踪客观地评估眼睛对视觉刺激的凝视行为，这允许对潜在的认知过程进行推断。我们测试了这一假设，即婴儿时期的社会取向会因早产而改变。
方法
对50例出生时平均胎龄(GA)为29(+1)(23(+2)~33(+0)周的早产儿和50例出生时平均(GA)为40(+2)(37(+0)~42(+3)周的足月儿进行了眼球跟踪，中位年龄为7个月。婴儿被呈现给三类日益复杂的社会刺激。使用远程眼动跟踪技术记录首次注视时间(TFF)和关注感兴趣区的注视时间(LT)。
结果
在所有三个任务中，早产儿在社交内容上的注视时间都比足月婴儿短：刷脸(注视眼睛减去嘴巴0.61s比1.47s，p=4.013)；突出脸任务(注视0.8s比1.34s，p=0.023)；社交优先看(1.16s比1.5s p=8.02)。在所有三个任务中，早产儿在整个刺激过程中给予包含社会内容的AOI的时间作为LT的比例都较低。这些结果并不能用两组人整体观看时间的差异来解释。
结论
眼球跟踪提供了早产后非典型认知的早期证据，并可能成为对有损害风险的婴儿进行分层的有用工具，以便进行旨在改善结局的早期干预。
BACKGROUND
Preterm birth is closely associated with neurocognitive impairment in childhood including increased risk for social difficulties. Eye tracking objectively assesses eye-gaze behaviour in response to visual stimuli, which permits inference about underlying cognitive processes. We tested the hypothesis that social orienting in infancy is altered by preterm birth.
METHODS
Fifty preterm infants with mean (range) gestational age (GA) at birth of 29(+1) (23(+2) -33(+0) ) weeks and 50 term infants with mean (range) GA at birth 40(+2) (37(+0) -42(+3) ) weeks underwent eye tracking at median age of 7 months. Infants were presented with three categories of social stimuli of increasing complexity. Time to first fixate (TFF) and looking time (LT) on areas of interest (AoIs) were recorded using remote eye tracking.
RESULTS
Preterm infants consistently fixated for a shorter time on social content than term infants across all three tasks: face-scanning (fixation to eyes minus mouth 0.61s vs. 1.47s, p = .013); face pop-out task (fixation to face 0.8s vs. 1.34s, p = .023); and social preferential looking (1.16s vs. 1.5s p = .02). Time given to AoIs containing social content as a proportion of LT at the whole stimulus was lower in preterm infants across all three tasks. These results were not explained by differences in overall looking time between the groups.
CONCLUSIONS
Eye tracking provides early evidence of atypical cognition after preterm birth, and may be a useful tool for stratifying infants at risk of impairment for early interventions designed to improve outcome.
