Linguistics theories debunked (partially)
Can learning a new language really change the way you see the world?
Of course this is dependent on what you mean by perception - in my case it has always changed my perception - mainly because effective communication with people who are different from me is invariably enlightening. I couldn't comment on mental mechanics though. But a good short article.

I think it is a click-bait article. The "weak Sapir-Whorf" theory has been repeatedly confirmed in that using a language which encodes certain concepts makes it easier to work with those concepts in that language. That has been shown using colours, directions, etc.
There are also the studies that working on topics in a non-native language enables one to more easily emotionally distance oneself from them.
So yes, new languages can in themselves affect how one percieves the world to a degree
