The purpose of this study was to compare the pragmatic skills of five children with Specific Language Impairments (SLI) and their Mean Length of Utterance-matched younger siblings, thus in part controlling for home language environment and expressive language level. Data were videotaped as mother-child free play in the home. Children's communicative acts were coded on three levels (social interchange, speech act, and conversational). Analysis of each level separately indicated generally comparable performance within sibling pairs. However, when the three levels were integrated into a measure of pragmatic flexibility, the children with SLI were found to demonstrate a more varied repertoire than their younger, normally developing siblings.
本研究的目的是比较五名患有特定语言障碍（SLI）的儿童及其语句平均长度匹配的年幼同胞的语用技能，从而在一定程度上控制家庭语言环境和表达性语言水平。数据是在家庭中母子自由玩耍时录像的。儿童的交际行为在三个层面进行编码（社交互动、言语行为和对话）。对每个层面分别进行分析表明，同胞对之间的表现总体相当。然而，当将这三个层面整合为一个语用灵活性指标时，发现患有SLI的儿童比其年幼的、发育正常的同胞表现出更多样化的技能。
