TL;DR: The central question in this article is: what is the canonical position of subjects?

TL;DR: Simplification of computational procedures suggests that compositionality and displacement fall together while order may be a reflex of sensorimotor externalization, conclusions that have far-reaching consequences.

TL;DR: The Unique Checking Constraint (UCC) as discussed by the authors is a developmental constraint that prevents a D-feature on DP from checking more than one feature on functional categories, thus forcing either AGR or TNS to be omitted.

TL;DR: Wilson and Sperber as mentioned in this paper treat utterance interpretation as a two-phase process: a modular decoding phase is seen as providing input to a central inferential phase in which a linguistically encoded logical form is contextually enriched and used to construct a hypothesis about the speaker's informative intention.

TL;DR: A comparison of English to other languages shows that contrary to the connectionist account, default suffixation is not due to numerous regular words reinforcing a pattern in associative memory, but to a memory-independent, symbol-concatenating mental operation.
