I wish there was more info on this alleged ability. It shouldn't be hard to show only Tatiana a picture of a number/person/etc, ask her to think about it, and see whether Krista can tell. Somehow it doesn't add up with the rest (shared motor abilities through the thalamus), and sounds more like the poetic but bogus claims that many twins make about one another.

it's a little difficult when they can see out of each other's eyes. granted one of them can only see out of one of the other's eyes, it's still difficult and probably so unique/case-by-case that it would be difficult to come to any conclusions

  True. Or limb taps would work instead, since nether have control over all of them.

  Since each of them has a "non-shared" eye, testing this is kind of straightforward, we can retry the same experiments that have been performed for split-hemisphere patients (where the left-brain personality has access only to the right eye and vice versa).

If the "talk" isn't in natural language, then it's a refutation of Wittgenstein's private language argument.

  I'm not sure about that. As I understand it, W's argument against private language is essentially that there is no way for a single person to be sure that they are following rules and that those rules are consistent over time. It also happens that none of the languages we are familiar with use thought as their medium (being signed, spoken, read, etc. instead), but if these twins are indeed using internal dialog (whatever that means) as a medium of communication, it could very well be regulated by rule following in a way that would satisfy W, don't you think?

according to this article they can do that http://ojs.library.ubc.ca/index.php/ubcujp/article/view/2521/182422 http://ojs.library.ubc.ca/index.php/ubcujp/article/view/2521... What's not clear is how they "listen" to each other. Stream-of-thought signals may reach the thalamus, but be suppressed from being uttered as they normally do with all of us. Yet the girls may have developed some connection that allows them to "read" each other.
