Whether the fault generally lies with flaws in the speaker's use of language, or in the listener's incapacity to understand, could be a research topic. The concern, shared by many here, that the illustrations, sentences, and process are off-putting and an important source of error should be examined.After reading the article, I'm much less surprised by the findings and still figuring that other factors are at play here. But almost none of the discussion I've seen (save a couple of comments on our original post) talks about the huge implications that are being mentioned:
- Is this really getting at a speaker's competence? (The article doesn't come down clearly on this, but see Stranded Preposition's comment on our original post.)
- How clearly do these results actually support usage-based approaches?
- Ultimately, does this show that grammar is really "grimmer than Chomsky claims"?
