2.4.1.3. Ratings of hazard and intent to comply
Participants rated each symbol in terms of perceived hazard and intent to comply on a scale from one to nine (not at all hazardous – extremely hazardous; not at all likely to comply – extremely likely to comply). Participants were instructed to use the zero key if they felt that they had no basis to judge. Presentation of ratings of hazard and intent to comply was blocked with randomized presentation of symbols within blocks. Participants completed the ratings of hazard prior to the ratings of intent to comply.
