This is a fascinating lecture by Lera Boroditsky on the effects of language on he content of thought as tested through a wide range of creative empirical studies. (You can also read this article , also by Boroditsky, which contains some of the information and citations.) She actually starts at 5:10 if you want to skip a great but superfluous opening video and get on with the lecture. The lecture itself is only about an hour.
Put timestamps of parts you want to recommend to others in the comments. Thanks to Cat and Bobby for the finds.
