The short version is that if the language you speak requires different verbs for the present and the future, it causes you to think about it differently. Depending on the magnitude of the effect, this has important implications for construal level theory. If your language allows you to think about the future in Near mode, it may allow you to think about it more rationally.
Previous discussion on one of Keith Chen's papers here.
Grammatical gender can have weak priming effects. eg. if your language codes "bridge" as masculine, you're more likely to describe one using words like "stout" and "strong", as opposed to languages with feminine bridges that are likely to be "graceful" or "soaring". If I recall correctly she also did some similar work with the way languages encode path and manner of movement (ie. in English I would say "he ran out of the room", while in French it's more like "he left the room running").
There's also a bunch of other related findings. eg. people generally conceptualise time/logical progressions as going in the same direction as their writing system, Russian speakers are faster to distinguish between light and dark blue than English speakers because in Russian they're two distinct colours, that sort of thing.
I'm still on the fence about this Keith Chen stuff. Most of those tasks I just described involve verbal labelling/categorisation, so it's not surprising to me that when you're explicitly asked to come up with words for things you would be primed by what kind of words and structures your language has. Thinking about the future seems less language-dependent than that.
I've no problem stomaching these findings; I have no objections to weak priming effects, differences in ease or speed of categorization and the like, and it doesn't seem like Boroditsky is pushing a case for anything more. It's strong relativism that I have misgivings about (as well as, in this case, the way the folks in the video seem to have overlooked controlling for factors other than the linguistic ones).
