T. Barlow et Ms. Wogalter, ALCOHOLIC BEVERAGE WARNINGS IN MAGAZINE AND TELEVISION ADVERTISEMENTS, Journal of consumer research, 20(1), 1993, pp. 147-156
Two experiments investigated the impact of warnings in mass-media adve
rtising in print (magazine) or broadcast (television) alcoholic bevera
ge ads. Experiment 1 showed that participants exposed to highly conspi
cuous warnings in print ads performed better on subsequent memory and
knowledge tests than those exposed to less conspicuous warnings. Less
conspicuous warnings were generally no better than no warnings. In exp
eriment 2, participants viewing broadcast commercials with both-modali
ty warnings generally performed better than those exposed to voice-onl
y or no warnings. Print-only warnings produced performance equivalent
to, or in one case lower than, both-modality warnings. Both experiment
s show that warnings in ads can communicate information if presented i
n a salient form.
