婴儿词汇习得清单的引入使我们能够从比以前更多的双语儿童那里收集关于早期词汇增长的详细信息，并开始探索在一系列双语学习环境中一种语言的增长与另一种语言的增长的关系。尽管如此，到目前为止，还没有标准化的工具能够充分描述正常的双语发展。基于单一语言经验的规范和里程碑低估了双语能力，因为它们只利用了双语者知识的一部分，并将没有他们实际拥有的复杂概念化归功于他们。双语测量，如Pearson，Fernández，and Oler(1993)和Muñoz-Sandoval，Cummins，Alvarado，and Ruef(1998)提出的，是对单语言测量的改进，因为它们涵盖了双语者知识的更大部分，但它们没有解决双语心理表征的更大复杂性。我们需要的是从对典型发育的双语儿童的观察中得出的标准，以及后续的同时效度和预测性效度。然而，双语者作为一个群体是如此的多样化，很难决定哪个子组(S)将是标准化的适当参考。在最近的研究综述中，讨论了评估双语词汇的困难和对临床实践的建议。
The introduction of vocabulary checklists for infant acquisition has allowed us to gather detailed information about early lexical growth from a broader number of bilingual children than before and to begin exploring the relation of growth in one language to growth in the other in a range of bilingual learning circumstances. Still, no standardized instruments to date give an adequate picture of normal bilingual development. Norms and milestones based on monolingual experience underestimate bilingual abilities in that they tap only a portion of the bilinguals' knowledge and credit them with less complex conceptualizations than what they actually possess. Double-language measures, like those proposed by Pearson, Fernández, and Oller (1993) and Muñoz-Sandoval, Cummins, Alvarado, and Ruef (1998), are an improvement over single-language measures as they encompass a greater portion of the bilinguals' knowledge, but they do not address the greater complexity of bilingual mental representations. What is needed are norms derived from observations of typically-developing bilingual children, followed up with measures of concurrent and predictive validity. However, bilinguals as a group are so diverse, it will be difficult to decide which subgroup(s) would be the appropriate reference to use for a standardization. In this review of recent studies, the difficulties involved in assessing bilingual vocabularies and recommendations for clinical practice are discussed.
