摘要

婴儿的眼球运动控制水平各不相同，极端情况下可能与自闭症有关。我们使用间隙-重叠眼动跟踪任务对 450 对双胞胎（225 对，57% 为单卵双胞胎，46% 为女性，年龄为 5-6 个月）的眼动情况进行了评估。间隙条件下的眼球运动潜伏期较短与2岁时父母评定的自闭症特征较多有关。该任务三种条件下的潜伏期主要由一个高度遗传的潜伏因素来解释，该因素可能代表了基本眼球运动效率和/或视觉信息处理方面的个体差异。此外，注意力脱离与独特的遗传因素有关，这表明涉及视觉注意力的遗传因素不同于涉及基本视觉信息处理和眼球运动效率的遗传因素。

Genetic and environmental contributions to individual differences in visual attention and oculomotor control in early infancy.

Infants differ in their level of eye movement control, which at the extreme could be linked to autism. We assessed eye movements in 450 twins (225 pairs, 57% monozygotic, 46% female, aged 5-6 months) using the gap-overlap eye-tracking task. Shorter latency in the gap condition was associated with having more parent-rated autistic traits at 2 years. Latency across the task's three conditions was primarily explained by one highly heritable latent factor likely representing individual differences in basic oculomotor efficiency and/or in visual information processing. Additionally, disengagement of attention was linked to unique genetic factors, suggesting that genetic factors involved in visual attention are different from those involved in basic visual information processing and oculomotor efficiency.

期刊介绍： As the flagship journal of the Society for Research in Child Development (SRCD), Child Development has published articles, essays, reviews, and tutorials on various topics in the field of child development since 1930. Spanning many disciplines, the journal provides the latest research, not only for researchers and theoreticians, but also for child psychiatrists, clinical psychologists, psychiatric social workers, specialists in early childhood education, educational psychologists, special education teachers, and other researchers. In addition to six issues per year of Child Development, subscribers to the journal also receive a full subscription to Child Development Perspectives and Monographs of the Society for Research in Child Development.
