An Old Task in New Clothes: A Preregistered Direct Replication Attempt of Enclothed Cognition Effects on Stroop Performance
Adam and Galinsky (2012) motivated their theory of enclothed cognition using experimental results showing that wearing a doctor's coat improved selective attention by reducing errors on incongruent Stroop trials. While many other studies have pursued extensions of this idea, there have been no published replications of this influence on the Stroop effect. This preregistered, direct replication attempt uses equivalence testing and the small telescopes framework from Simonsohn (2015) to argue that such an effect, if it exists, is too small to have been reliably detected under the original design. Theoretically predicted sequential effects as small as 7 ms were successfully detected at α =.05, indicating that the failure to find an effect of lab coat is likely not due to power limitations or poor experimental technique.
