In two experiments, we examined the effect of attitude dissimulation a
nd truthful attitude expression on attitude accessibility, which is th
e ease with which an attitude is retrieved from memory. In the first e
xperiment, 161 subjects lied about their attitudes toward some attitud
e objects and expressed their true attitudes toward other attitude obj
ects. Next, as our measure of attitude accessibility, subjects were as
ked to express quickly and accurately their true attitudes toward (a)
the objects that they had lied about, (b) the objects that they had ev
aluated truthfully, and (c) other objects that they had not evaluated
at all. Results indicated that both attitude dissimulation and truthfu
l attitude expression caused attitudes to become more accessible (i.e.
, more quickly recalled) than if the attitudes had not been previously
expressed. In the second experiment, we tested the hypothesis that at
titude dissimulation increases attitude accessibility only when the di
ssimulation causes conscious recall of one's true attitude. Results su
pported this hypothesis. The implications of these results for predict
ing the effect of lying on attitude-behavior relations is highlighted.
