Exposure to, awareness of, beliefs about, and memory for the warning o
n the recently required Arizona alcohol warning poster were measured i
n a sample of college students before (N = 362) and after (N = 332) th
e legislation became effective on January 1, 1992. The introduction of
the warning poster was associated with greater exposure, awareness, a
nd memory. The authors found inconsistent evidence for an association
between the introduction of the warning poster and beliefs. Secular tr
ends did not appear to be responsible for these changes.
