Three experimental studies analyzed the extent to which correlations between implicit and explicit measures of (anti-Arab) attitudes depend on the conditions in which these measures are applied. The first study revealed that the correlation increased when the explicit measure was applied in conditions of time-pressure and cognitive load. The second study showed that, under these conditions, both implicit and explicit measures predicted stereotypic attributions. The third study confirmed that the correlation between both measures increased when participants were previously familiarized with the logic that underlies the use of implicit measures. The theoretical and methodological implications of these results are discussed.
