I am a native Slovenian speaker who speaks a bunch of different languages to varying degrees of "speak". I definitely feel each of them changes my personality somewhat in its own way. I assume part of it is due the language used and part due to cultural traits you pick up when you learned it. Would be surprised if there was no feedback loop between language and cultures that use it.
