This study of 195 (108 boys) children seen twice during infancy (Time 1: 4.12 months; Time 2: 14.42 months) aimed to investigate the associations between and infant predictors of executive function (EF) at 14 months. Infants showed high levels of compliance with the EF tasks at 14 months. There was little evidence of cohesion among EF tasks but simple response inhibition was related to performance on two other EF tasks. Infant attention (but not parent-rated temperament) at 4 months predicted performance on two of the four EF tasks at 14 months. Results suggest that EF skills build on simpler component skills such as attention and response inhibition.
这项针对 195 名（108 名男孩）儿童的研究在婴儿期进行了两次观察（时间 1：4.12 个月；时间 2：14.42 个月），旨在调查 14 个月时执行功能（EF）的相关性和婴儿预测因素。婴儿在 14 个月时对 EF 任务表现出很高的遵从性。EF 任务之间几乎没有凝聚力的证据，但简单的反应抑制与另外两项 EF 任务的表现相关。4 个月时婴儿的注意力（而非父母评定的气质）预测了 14 个月时四项 EF 任务中的两项任务的表现。结果表明，EF 技能建立在更简单的组成技能上，例如注意力和反应抑制。
