TL;DR: Action-sentence compatibility effect (ACE) as discussed by the authors is a well-known demonstration of the role of motor activity in the comprehension of language, and participants are asked to make sensibility judgments on sentences by producing movements toward the body or away from the body.

TL;DR: It is suggested that sensitivity to the relationship between functional morphemes and content words, rather than sensitivity to either independently, drives the development of early grammatical knowledge.

TL;DR: Understanding the core computational principles of language development is an important step in this direction and is complemented by a greater understanding of the learner as situated in a rich and supportive context that evolves over time.

TL;DR: It is suggested that cues in the speech stream may help children resolve the ambicategoricality problem, and in early language production, children's cross-category production mirrors the statistics of their linguistic environments, suggesting that they are distinguishing noun and verb uses of individual words in natural language exposure.
