This study examined patterns of attention toward affective stimuli in a longitudinal sample of typically developing infants (N = 357, 147 females, 50% White, 22% Latinx, 16% African American/Black, 3% Asian, 8% mixed race, 1% not reported) using two eye-tracking tasks that measure vigilance to (rapid detection), engagement with (total looking toward), and disengagement from (latency to looking away) emotional facial configurations. Infants completed each task at 4, 8, 12, 18, and 24 months of age from 2016 to 2020. Multilevel growth models demonstrate that, over the first 2 years of life, infants became faster at detecting and spent more time engaging with angry over neutral faces. These results have implications for our understanding of the development of affect-biased attention.

生命最初 2 年情感注意力的发展模式

这项研究检查了典型发育婴儿的纵向样本中对情感刺激的注意模式（N  = 357，147 名女性，50% 白人，22% 拉丁裔，16% 非裔美国人/黑人，3% 亚洲人，8% 混血儿，1 % not reported）使用两个眼动追踪任务测量对（快速检测）的警惕性、参与（完全看向）和脱离（延迟看向别处）情绪面部配置。从 2016 年到 2020 年，婴儿分别在 4、8、12、18 和 24 个月大时完成了每项任务。多层次成长模型表明，在生命的前 2 年里，婴儿在发现愤怒方面变得更快，并且花更多时间处理愤怒中性面孔。这些结果对我们理解影响偏向注意的发展具有重要意义。
