Two experiments investigated cognitive processing and attitudes under
different motivations. In Experiment 1, 63 participants had either str
ong nondirectional (accuracy) or directional (defensive, impression) m
otives. Accuracy motivation resulted in extensive objective processing
Defensive motivation resulted in extensive biased processing. Impress
ion motivation resulted in extensive processing that was directional i
n some measures but balanced in other measures. Cognitive processing m
ediated the effects of motivation on attitudes, which were stable acro
ss measurements. In Experiment 2, 44 participants processed under two
combined strong motivations. Accuracy was successfully combined with d
irectional motivation in both processing and attitudes. It reduced bia
s when combined with impression motivation but not when combined with
defensive motivation. Two opposing directional motivations were diffic
ult to combine, and participants eventually abandoned extensive proces
sing.
