Should You Put an Emoticon on Your Flag? How Subliminal Visual Stimuli Can Change Political Opinions

Political objects, like national flags, arouse emotions even when they are subliminal stimuli. Through two experiments that show subliminal stimuli to the subjects, this article analyzes if those emotions are positive or negative ones—that is to say, if they enhance an inclusive reaction or an excluding one. Besides, the article compares the intensity of the flag’s emotional effect with that of the emoticons, which are figures intended to represent emotional reactions or states. Findings confirm that the Spanish flag, as a subliminal stimulus, influences the opinions of the participants. However, it has had a lower effect than that obtained in previous, similar experiments. Emoticons produce a much more intense type of response than flags. The experiments (n = 85; n = 126) enlarge the knowledge about the emotional effects of political objects of nonconscious perception. Besides, we present an original methodological contribution: the use of emoticons to alter political views.
