We don't need even need to look at the science formally. We can look at it at a different level. If we know a little about how the brain works then a phenomenon like this might become obvious. Language affects how you think, there is no question about that. People who have a dirtier vocabulary will think dirtier, people who have a more formal vocabulary with think more formally, etc. If the language you speak makes it harder to talk dirty then you will probably talk less dirty. This will in-turn affect how you think. There is a native tribe that does not have words for left, right, ahead or behind, but instead they relate every direction to the cardinal directions. So, instead of referring to your foot as your left foot, this native tribe will sometimes refer to it as your west foot, sometimes as your northeast foot, etc. This simple example shows how different your thought patterns can be based on what words you use. These natives will always have in their minds where north is, where any "normal" outsider will have to spend a second or two locating north first. Their brains are almost set up to think in a different way. Language is complex as hell, but it makes sense that if a word, or expression is used more often in one culture than another, that its speakers will be more influenced by that word or expression. Can you imagine if in English there was no easy way to say "sex"? In English there are dozens of ways to refer to sex and other sexual acts, and many only take one or two syllables. What if the easiest way to refer to sex was to say a 5-syllable word? I bet that would have some influence on how much we think about sex. We might still be able to think of the act of sex easily (the images, memories in our heads), but thinking about/using the word will take too much energy and as a result will be used less. Can you imagine if the word "sex" was used less on TV, in music, etc. simply because the word was too long and no longer fit nicely within the script/lyrics? Now, it's not too much of a leap to see that having a language where present-tense and future-tense are less distinct from each other will influence the speaker of that language into making less of a distinction between the present & future. How much influence? Who knows? That, we need formal, nitty-gritty science for.
