His idea was that the language that would be most resistant to damage would be
the language that the patient was speaking at the time of the stroke.
Petri's considered a series of cases, so he considered cases of people who for
example, one gentlemen who knew German as a native language.
And then learned several languages later in life.
At 50, 60 years of age he had a stroke and what he found was that this patient was
actually better able to speak the languages that he was speaking at the time
of insult, than the one that he learned, as a child.
Suggesting that there was something about what language was being used at
the time of stroke that might actually benefit that, that language and
allow it be used, after the incident.
Now ,you might be asking well the hold on, how can it be that
it's the most recent one, wouldn't that be nece, maybe that's not the best language?
