3. A psychologist wants to determine which of three advertisements is most likely to encourage teens not to drink. To assess the impact of each ad, he asks a sample of teenagers to view each ad and to rate its effectiveness on a scale of 1 (not at all effective) to 7 (very effective). One ad used words only (no-cues condition), a second ad used a generic abstract picture (generic-cues condition), and a third showed a picture of a teen drinking and impacts (smoking-related cues condition).
