Aa. Romero et al., THE COGNITIVE MEDIATION HYPOTHESIS REVISITED - AN EMPIRICAL RESPONSE TO METHODOLOGICAL AND THEORETICAL CRITICISM, Personality & social psychology bulletin, 22(7), 1996, pp. 651-665
The cognitive mediation hypothesis has become a well-established assum
ption in persuasion theory. However, several theoretical and methodolo
gical criticisms have been raised to call this assumption into questio
n. Three experiments that address these criticisms were conducted to p
rovide a more direct test of the cognitive mediation hypothesis. Using
the forewarning effect as a testing arena, Experiment 1 demonstrated
that interference with either motivation or ability to counterargue re
duced forewarning-induced resistance to persuasion. Experiment 2 demon
strated that exposure to counterarguments generated by others and self
-generated counterarguments were functionally equivalent and redundant
. Experiment 3 used a path-analytic approach to demonstrate that the p
ersuasion differences produced by forewarning were eliminated by covar
ying the effect of cognitive responses generated between forewarning a
nd message exposure. Taken together, the three experiments provide con
verging support for the cognitive mediation hypothesis, reconfirming t
he central role of cognition in the persuasion process.
