>Research on adult individuals with aphasia has demonstrated that math, theory of mind, and many other cognitive abilities are independent from language.4 Patients with severe language impairments perform comparably to the rest of us when *asked* to complete arithmetic tasks, reason about people’s intentions, determine physical causes of actions, or decide whether a drawing depicts a real-life event.

Ok something is weird here. How were they *asked* to do these things if they have no language skills. Is the author brushing over the fact that they still had language skills, but they were not as good as they used to be? In which case all her conclusions about what we can do without any language skills are irrelevant as they don't apply, which would explain why she brushes over this point, I guess.
