We hypothesize that while evaluative priming involves proprioceptive cues, the IAT is representational due to its structural features and the specific algorithm upon which the IAT-effect rests. As predicted, evaluative priming is shown to rely on differential facial muscle activity while the IAT as a measurement instrument is not influenced by proprioceptive information. Evaluative priming does not yield differential responsiveness for congruent and incongruent trials when facial muscle activity is inhibited whereas the IAT-effect is shown to be impervious to such inhibition. Implications for the underlying mechanisms of implicit measures are discussed.
