& Bloom, 2008). A number of tasks, collectively called implicit measures, are designed to measure unintentional attitude effects (Wittenbrink & Schwarz, 2007). There is lit-tle evidence of whether people know that unintentional eval-uations influenced their performance in any of these tasks (for an exception, see Monteith, Voils, & Ashburn-Nardo, 2001). The present research investigated people’s percep-tion of the attitude effects in the affective misattribution pro-cedure (AMP; Payne, Cheng, Govorun, & Stewart, 2005). In the AMP, participants observe a prime (e.g., a picture of Hillary Clinton), quickly followed by an unfamiliar target (a Chinese pictograph for non-Chinese readers). Participants are instructed to ignore the prime and evaluate the target as pleasant or unpleasant. Despite the instructions, Payne et al. (2005) found that primes nonetheless influenced judg-ments of the targets. People rated targets that appeared after pleasant stimuli (e.g., a baby) as more pleasant than targets that appeared after unpleasant stimuli (e.g., a snake). The presumed mechanism of this effect was that the primes automatically activate a positive or negative reaction that is misattributed to the target. The AMP is gaining widespread use as an implicit measur
