Examining the impact of distance as a contextual cue in evaluative conditioning.

According to a symbolic perspective on EC, pairings constitute a relational contextual cue in the environment. It is the relationship between stimuli as cued by the pairing (i.e., pairings = similar) that determines the observed change in liking. Across five pre-registered studies (N = 747) we manipulated the absolute or relative distance between different pairs of conditioned (CS) and unconditioned stimuli (US) under the assumption that this would influence the type of relation that the pairings would cue (i.e., close = similar; far = different). In all five studies we obtained repeated and strong evidence that stimulus pairings led to changes in implicit and explicit evaluations. Although we found that these effects were moderated by absolute distance manipulations, evidence did not emerge indicating that those same effects were moderated by relative distance manipulations. These findings fail to provide strong support for a symbolic perspective on EC. We discuss the implications of our findings as well as future research in this area.
