Abstract：
UNASSIGNED: The testing of visuocognitive development in preterm infants shows strong interactions between perinatal characteristics and cognition, learning and overall neurodevelopment evolution. The assessment of anticipatory gaze data of object-location bindings via eye-tracking can predict the neurodevelopment of preterm infants at the age of 3 years; little is known, however, about the early cognitive function and its assessment methods during the first year of life.
UNASSIGNED: The current study presents data from a novel assessment tool, a Delayed Match Retrieval (DMR) paradigm via eye-tracking was used to measure visual working memory (VWM) and attention skills. The eye-tracking task that was designed to measure infants\' ability to actively localize objects and to make online predictions of object-location bindings. 63 infants participated in the study, 39 preterm infants and 24 healthy full term infants - at a corrected age of 8-9 months for premature infants and similar chronological age for full term infants. Infants were also administered the Bayley Scales of Infant and Toddler Development.
UNASSIGNED: The analysis of the Bayley scores showed no significant difference between the two groups while the eye-tracking data showed a significant group effect on all measurements. Moreover, preterm infants\' VWM performance was significantly lower than full term\'s. Birth weight affected the gaze time on all Areas Of Interest (AOIs), overall VWM performance and the scores at the Cognitive Bayley subscale. Furthermore, preterm infants with fetal growth restriction (FGR) showed significant performance effects in the eye-tracking measurements but not on their Bayley scores verifying the high discriminatory value of the eye gaze data.
UNASSIGNED: Visual working memory and attention as measured via eye-tracking is a non-intrusive, painless, short duration procedure (approx. 4-min) was found to be a significant tool for identifying prematurity and FGR effects on the development of cognition during the first year of life. Bayley Scales alone may not pick up these deficits. Identifying tools for early neurodevelopmental assessments and cognitive function is important in order to enable earlier support and intervention in the vulnerable group of premature infants, given the associations between foundational executive functional skills and later cognitive and academic ability.

摘要：
■对早产儿视觉认知发育的测试表明，围产期特征与认知之间存在很强的相互作用，学习和整体神经发育进化。通过眼睛跟踪评估对象-位置绑定的预期凝视数据可以预测3岁早产儿的神经发育；鲜为人知，然而,关于生命第一年的早期认知功能及其评估方法。
■当前的研究提供了来自新型评估工具的数据，通过眼动追踪的延迟匹配检索（DMR）范例用于测量视觉工作记忆（VWM）和注意力技能。眼动追踪任务旨在测量婴儿主动定位对象并在线预测对象位置绑定的能力。63名婴儿参加了这项研究，39名早产儿和24名健康足月婴儿-早产儿的矫正年龄为8-9个月，足月婴儿的实际年龄相似。还给婴儿施用了Bayley婴儿和幼儿发育量表。
■对Bayley评分的分析显示两组之间没有显着差异，而眼动追踪数据显示对所有测量值均具有显着的组效应。此外，早产儿的VWM表现明显低于足月。出生体重影响所有感兴趣区域（AOI）的注视时间，VWM的总体表现和认知Bayley分量表的得分。此外，胎儿生长受限(FGR)的早产儿在眼动追踪测量中表现出显著的性能效应,但对他们的Bayley评分没有影响,这证明了眼睛注视数据的高判别值.
■通过眼动追踪测量的视觉工作记忆和注意力是非侵入性的，无痛,短期程序（大约。4分钟）被发现是识别早产和FGR对生命第一年认知发展影响的重要工具。仅BayleyScales可能无法弥补这些不足。确定用于早期神经发育评估和认知功能的工具对于早期支持和干预早产儿的脆弱群体非常重要。考虑到基本的执行功能技能与后来的认知和学术能力之间的关联。
