I don't know about these study conclusions; the secret directions seem more like advertisements to me: Someone whispers "Please walk" and my brain (consciously or otherwise) thinks about it and realizes I'd like a drink, just like if I drive past a McDonald's billboard and think, "Hmm, french fries would hit the spot right now." Someone flashes "close the window" and it draws attention to the fact that actually, I am kind of chilly and would like the window to be closed. It doesn't mean the desire was made up, just not considered until it got the spotlight.
