Adult and adolescent Ss were asked to list possible consequences of ei
ther accepting or declining opportunities to engage in various potenti
ally risky behaviors (e.g., drinking and driving, skipping school to g
o to a mall). Response patterns were quite similar for these adults an
d adolescents, indicating shared beliefs about the possibilities. Alth
ough taking and avoiding a risk are logically complementary actions, t
hey did not prove to be psychologically complementary. Other compariso
ns showed systematic differences in the consequences produced for one-
time and regular (or repeated) versions of the same behaviors, as well
as for open-ended and closed-ended response modes. These results are
discussed in terms of their methodological implications for studying r
isk perceptions, their practical implications for influencing adolesce
nts' risk behaviors, and their theoretical implications for understand
ing intellectual development.
