本研究探讨了句子中断与发展语法儿童所说句子的长度和复杂程度之间的关系。这项研究在设计上是横断式的，使用了26个典型发育中儿童(2岁；6到4岁；0岁)和主要照顾者之间的自然主义对话互动样本。这些儿童产生的主动陈述句被编码为存在干扰，语素和单词的长度，以及从句的复杂性。结果表明，对于大多数儿童来说，被打断的句子往往比流利的句子更长、更复杂。用产出性句法指数衡量，长度和复杂性差异的大小与儿童的语法发展呈正相关。研究还发现，即使在句子长度保持不变的情况下，断句和流利句子的平均复杂性之间的差异也会随着语法的发展而增加。随着语法的发展，断断续续的句子更容易成为处于儿童生产能力前沿的句子。虽然这些更高级的语法结构是孩子语法能力的一部分，但如果不增加处理困难的风险，孩子就不能说出这些句子。这一结果与关于成人判刑产生的增量和程序性的建议是一致的。
This research explored the relationship between sentence disruptions and the length and complexity of sentences spoken by children developing grammar. The study was cross-sectional in design and used samples of naturalistic, conversational interaction between 26 typically developing children (ages 2;6 to 4;0) and a primary caregiver. The active, declarative sentences produced by these children were coded for the presence of disruption, length in morphemes and words, and clausal complexity. The results showed that, for the majority of the children, disrupted sentences tended to be longer and more complex than fluent sentences. The magnitude of the differences in length and complexity was positively correlated with the children's grammatical development, as measured by the Index of Productive Syntax. It was also found that differences between the average complexity of disrupted versus fluent sentences increased with grammatical development even when sentence length was held constant. As grammatical development proceeded, disrupted sentences were more apt to be sentences on the "leading-edge" of the child's production capacity. Although these more advanced grammatical structures are part of the child's grammatical competence, the child cannot produce these sentences without an increased risk of processing difficulty. The results are congruent with proposals concerning the incremental and procedural nature of adult sentence production.
