两项研究考察了学龄前儿童对与新奇动作相结合的无意义单词的动词解释能力。实验1研究了特定的语言障碍（SLI）和年轻的儿童，正常发展的同龄人收集动词的解释时，已经知道的名字的数字执行小说的行动。两组孩子的表现相似，准确的方式。实验2要求学龄前儿童完全依靠形态句法信息来确定新单词是否代表一个物体或动作。当提供冗余的形态句法线索，儿童与SLI和语言和年龄匹配的同龄人成功地确定了新的话，指的是对象，但不是那些指的是行动。只有年龄匹配的正常同龄人在名词解释依赖于单个语法词素时高于机会水平（例如，“我们想要Koob”与“我们想要Koob”）。研究结果表明，学龄前儿童，无论他们是否有语言障碍，有困难使用形态句法信息引导动词。此外，冗余而不是单一的形态句法线索促进了名词的自举。
Two studies examined preschoolers' ability to assign verb interpretations to nonsense words encountered in conjunction with novel actions. Experiment 1 examined the ability of children with specific language impairment (SLI) and younger, normally developing peers to glean a verb interpretation when the name of the figure performing the novel action was already known. The two groups of children performed in a similar, accurate fashion. Experiment 2 required preschoolers to rely exclusively on morphosyntactic information to determine whether the novel word represented an object or action. When provided with redundant morphosyntactic cues, children with SLI and language- and age-matched peers succeeded in identifying the novel words that referred to objects but not those that referred to actions. Only the age-matched normal peers were above chance levels when a noun interpretation depended on a single grammatical morpheme (e.g., 'We want the koob' versus ;We want to koob'). The findings suggest that preschoolers, whether or not they have language impairment, have difficulty using morphosyntactic information to bootstrap verbs. Furthermore, redundant but not single morphosyntactic cues facilitate the bootstrapping of nouns.
