Numerous studies suggest an association between language and executive function (EF), but evidence of a developmental relationship remains inconclusive. Data were collected from 75 deaf/hard-of-hearing (DHH) children and 82 hearing age-matched controls. Children were 6-11 years old at first time of testing and completed a battery of nonverbal EF tasks and a test of expressive vocabulary. These tasks were completed again 2 years later. Both groups improved their scores on all tasks over this period. DHH children performed significantly less well than hearing peers on some EF tasks and the vocabulary test at both time points. Cross-lagged panel models showed that vocabulary at Time 1 predicted change in EF scores for both DHH and hearing children but not the reverse.
许多研究表明语言和执行功能（EF）之间存在关联，但发展关系的证据仍不确定。数据来自 75 名聋人/重听儿童和 82 名听力年龄匹配的对照组。儿童在第一次测试时年龄为 6-11 岁，完成了一系列非语言执行功能任务和表达词汇测试。这些任务在两年后再次完成。在这段时间内，两组儿童在所有任务上的得分都有所提高。聋人儿童在一些执行功能任务和词汇测试上的表现明显不如听力儿童，在两个时间点都是如此。交叉滞后面板模型显示，词汇量在时间 1 上预测了聋人和听力儿童执行功能分数的变化，但反之则不然。
