Recall that aronson and his colleagues asked college students either to compose a persuasive message advocating the use of condoms or to compose and deliver their message in front of a video camera. in addition, half of the participants in each group were made mindful of the times that they didn't use condoms. after completing these tasks, participants were allowed to purchase condoms at a low price. those students who made a video after being primed to think about their own condom use purchased the most condoms. what do the findings of this experiment demonstrate?
