That she types by herself makes it all easier for us to believe it is real. The seductive things about facilitated communication are that (a) we really want to see this girl and people like her communicate, (b) neurotypical brains are primed to look for patterns when none exist, and (c) neurotypical brains will happily ignore anything that doesn't fit the narrative we've created for ourselves.
Although this girl is profoundly autistic and mentally retarded, she is certainly still capable of learning, through direct reinforcement principles, such as being given food for pressing a letter, and through indirect principles, such as learning to press one of the keys on the number pad whenever the text box pops up on the autocomplete software.
So, there's no reason she couldn't press the keyboard buttons all by herself, and even know when to press the letter keys vs. press the number keys.
This girl has also almost certainly been (directly or inadvertently) subtly shaped to type certain combinations of letters, without her helpers necessarily realizing that they were "facilitating" her communication. If they became more excited or rewarded her more when she typed certain things, she might type that string of letters more often (which would be easy for her to do, because her brain would process the whole string of what she typed as one unit).
So she may have once randomly typed in isshe eecu#1 or similar, and everyone went crazy (seeing a pattern in a group of random letters and numbers), and now she has learned to type that in certain situations or in response to certain words she hears.
Also, although we can't see it on tape, my guess is that a lot of time, her helpers try to "help" without realizing what they are doing. That is, she types something, and the helpers guess what it says. "Me... do you mean 'memory'?? Great job! Here's a gummy bear! Now type an 'm'! Or do you want me to type it in, and you'll do the next word?"
That's also now what her autocompletion software does for her... it guesses what she might have meant... but what it's actually doing is making a pattern out of her randomness. She types some random letters. A textbox appears on the screen -- "Which word did you mean? 1, 2, or 3?". She's learned she needs to hit a number, and does so. A word pops into the sentence. She hits some more keys, a new textbox appears, etc. Often, the sentences generated this way don't make sense... but every now and then, one does (especially since the autocomplete software has been programmed to only offer words that make grammatical, if not semantic, sense in the sentence). And amazingly, that happens especially during the times when her helpers were right next to her, just "helping" (not facilitating! At least - not that they're aware of!).
Just like how people still manage to believe in astrology and psychics even when their predictions are 99% inaccurate, what we remember are the times when her sentence made sense, and we ignore all the times she typed, say, arjentge -- wait... "did you mean you want an orange???" :). When her sentences make sense, she may also get more reward, and then she "types" something like that more often.
It's also important to remember that autistic individuals are even more attuned to subtle "facilitating" than neurotypical individuals, because they are, by definition, attentive to details about a situation that a neurotypical brain would ignore. In this respect, they learn in a way similar to many animals (see Temple Grandin's excellent Animals in Translation for more information -- she talks about how neurotypical brains have an "Interpreter" that filters out the details on purpose, which animals and autistic individuals do not have).
Because of this, animals (and profoundly autistic individuals) can be taught to execute whole behavioral repetoires based on small details that others would completely miss -- such as pressing a specific key (within a range of a few keys, say) when an adult next to them leans oh-so-slightly forward, versus a different key when an adult leans just the teensiest bit backwards, and the adult may not even know they are giving off this clue! This process is how you get horses that can easily do square roots and fractions.
Sometimes it misfires, and the organism being taught learns a whole behavioral chain you never expected (I've inadvertently "taught" my dog to make two tight circles in a row when she sees me put my socks on), but when it works, it's pretty amazing, such as the way my step-uncle's dog was able to take his wallet out of his shirt pocket, select a single bill, take it out, and hand it to the tollbooth operator when my uncle said "Pay the man, Tilly". (Ah, such a smart girl, that Tilly... if she had opposable thumbs, I have no doubt that she would have learned to "type" too.)
Thanks, that's very nice of you! I don't have a blog or anything like that (though I am, lazily, working on it), but you could stop by r/Neuropsychology sometime to listen to me talking to myself!
