The early production of nine cohesive devices during narration about personal experience was examined in an 18-month longitudinal study of 10 children between approximately age 2;0 and 3;6. The specification of noun phrases and types of noun errors were also explored. The number of cohesive ties increased with both age and MLU, due to increased pronominal reference and conjunctions (while clausal and verbal ellipsis decreased). Specific cohesive devices also were acquired at different MLU levels. Most noun phrases were non-problematic and errors declined with increasing age and MLU; specifically, noun omissions declined. However, when new nouns were introduced, approximately one out of five were ambiguous throughout the study. Thus, children's narratives become more comprehensible with age as cohesive links increase, and noun errors decrease, but at 3;6 children are still having difficulty properly managing the introduction of novel nouns.
在一项针对10名年龄约在2岁0个月至3岁6个月之间儿童的为期18个月的纵向研究中，对讲述个人经历时九种衔接手段的早期运用情况进行了考察。同时还探究了名词短语的具体情况以及名词错误的类型。衔接纽带的数量随着年龄和平均语句长度（MLU）的增加而增多，这是由于代词指代和连词的使用增加（而从句省略和动词省略减少）。特定的衔接手段也是在不同的平均语句长度水平上习得的。大多数名词短语没有问题，并且错误随着年龄和平均语句长度的增加而减少；具体而言，名词省略减少。然而，在引入新名词时，在整个研究过程中大约五分之一的新名词存在歧义。因此，随着衔接纽带的增加和名词错误的减少，儿童的叙述随着年龄增长变得更易理解，但在3岁6个月时，儿童在正确处理新名词的引入方面仍存在困难。
