Abstract:	The over-the-counter medication you get at the pharmacy for your hay fever comes with a verbal warning that in rare cases, side effects such as blurred vision may occur. How does this warning affect your driving behavior (e.g., the assessment of the risk of a car accident)? Now, recent studies have shown that pharmaceutical pictograms, visual aids to the application, dosage, but also to the side effects of medications, improve their correct intake because, for example, they attract more attention. However, little is known about whether and how such pictograms influence risk perception. To investigate this, participants (N = 306) in an online study were shown a medication package that provided either visual (i.e., pictograms) or verbal information about the rare occurrence of side effects (factor: format). The number of side effects could be 1 or 3 (factor: number). Participants who were randomly assigned to one of the four conditions had to indicate the probability of a car accident (1 – 100%), and their driving intention (do not drive anymore, drive only a short distance of 30 minutes or less, drive a longer distance of more than 30 minutes) because of taking the medication. Regarding both dependent measures – probability of a car accident and driving intention – we found only significant main effects of format (both p’s < .05). More precisely, with the visual presentation format of side effects, not only was the likelihood of a car accident rated lower than with the verbal presentation format (33.7 vs. 40.2%), but the willingness not to drive was also lower (9 vs. 15%). Note that across all conditions only 23.5% correctly rated "rarely" as being between 0.01 and 0.1%. Overall, a visual representation of side effects using pictograms on a medication package seems to reduce risk perception.
