Researchers used neural language models to investigate whether child-directed language (CDL) is optimized for word learning. By training models on CDL versus adult-directed language (ADL) and manipulating syntactic or lexical information, they found that disruptions to syntax impaired learning across all datasets. Models trained on spoken CDL and ADL demonstrated greater resilience to these disruptions compared to written input, suggesting that the spoken register, rather than CDL specifically, may confer advantages for verb meaning acquisition.

IMPACT Suggests that the spoken register, rather than child-directed language specifically, may offer advantages for verb meaning acquisition in AI models.
