Children's use of present tense suffixes is less productive than that of their parents, after correcting for sample size and lexical knowledge, according to a recently established approach for the study of inflectional productivity. This article expands on this technique by providing precise estimates of early grammatical productivity through systematic random sampling and allowing for developmental assessment. Two cross-linguistic comparisons are given in the results of this study. Two Spanish-speaking children and their parents are compared with four English-speaking children and their parents. The second comparison examines potential differences in productivity throughout developmental stages using the same six children's speech. The findings indicate that Spanish-acquiring children are less productive than their parents while utilising the paradigm under study, but that productivity levels increase over time. In contrast, the English-speaking children's morphosyntactic production mirrors that of their parents. Although the primary focus of this research is methodological, these findings have consequences for theoretical theories arguing either rule abstraction or a restricted generalisation of early exemplars.
根据最近用于研究屈折变化生成能力的一种方法，在校正样本量和词汇知识后，儿童对现在时后缀的使用不如其父母那样具有生成能力。本文通过系统随机抽样提供早期语法生成能力的精确估计并进行发展性评估，对该技术进行了拓展。本研究结果给出了两项跨语言比较。将两名说西班牙语的儿童及其父母与四名说英语的儿童及其父母进行了比较。第二项比较使用相同六名儿童的言语，考察了整个发展阶段生成能力的潜在差异。研究结果表明，习得西班牙语的儿童在使用所研究的词形变化模式时，其生成能力不如其父母，但生成能力水平会随着时间的推移而提高。相比之下，说英语的儿童的形态句法生成能力与其父母的相似。尽管本研究主要关注方法，但这些发现对主张规则抽象或早期范例有限泛化的理论具有影响。
