The study asked whether Deaf mothers seek to exploit the iconicity in signed languages to facilitate their infants' word learning. Two longitudinal case studies followed modifications that 2 Deaf mothers applied to their input while interacting with their hearing infants. Both mothers were sensitive to the communicative abilities of their infants in different periods of language acquisition, and adapted their inputs accordingly. In the prelinguistic period, infant-directed input was characterized by repetitiveness to facilitate the infant's visual perception. During the mid-one-word period, the mothers used exaggerated iconic productions to promote form-meaning mapping. During early syntax development they used adultlike directed signing, applying phonetic reduction modifications to ease and speed up signing. The results support the hypothesis that iconicity plays a role in signed language development and that, in general, modifications act as scaffolding for language learning.

输入修改的发展路径和在早期听力婴儿-聋母亲互动中使用图像。

该研究询问聋哑母亲是否寻求利用手语的象似性来促进婴儿的单词学习。两个纵向案例研究遵循了 2 位聋哑母亲在与听力婴儿互动时对其输入进行的修改。两位母亲都对婴儿在语言习得不同时期的交际能力很敏感，并相应地调整了他们的输入。在前语言时期，婴儿导向输入的特点是重复性，以促进婴儿的视觉感知。一字中期，妈妈们用夸张的标志性作品来推动形意映射。在早期的语法开发过程中，他们使用了成人式的定向手语，应用了语音缩减修改来简化和加快手语。
