Matters Order: The Role of Information Order on Implicit Impression Formation

A classic finding in the person perception literature is that information order is an important factor in the impressions we form of others. But how does order influence the formation of implicit evaluations? In three preregistered experiments including nearly 900 participants, we find evidence for a strong primacy effect even at the implicit level. This occurred on an affect misattribution procedure (Study 1), an evaluative priming task (Study 2), and an implicit association test (Study 3). These findings suggest that, just as explicit impressions are susceptible to primacy effects, so too are implicit ones. Implications for theories of evaluative conditioning and attitudes are discussed.
