People can systematically match information from different senses, and these matches are known as crossmodal correspondences. Most work on these correspondences has explored how they might arise through neural mechanisms, statistical covariance in the environment, or semantic associations (e.g., Spence, 2011). Recently, Palmer, Schloss, Xu, & Prado-León (2013) demonstrated that at least some color-music correspondences can be explained by emotional mediation. The present study investigates the emotion mediation hypothesis for correspondences between odor and music, testing whether the strength of odor-music matches for particular odors and musical selections can be predicted by the similarity of the emotional associations with the odors and music. We found that perceived matches were higher when the emotional responses were similar and that a model including emotional dimensions captured a significant amount of the variance of match scores. These results provide new evidence that crossmodal correspondences are mediated by emotions.

Replication studies in psychological science sometimes fail to reproduce prior findings. If these studies use methods that are unfaithful to the original study or ineffective in eliciting the phenomenon of interest, then a failure to replicate may be a failure of the protocol rather than a challenge to the original finding. Formal pre-data-collection peer review by experts may address shortcomings and increase replicability rates. We selected 10 replication studies from the Reproducibility Project: Psychology (RP:P; Open Science Collaboration, 2015) for which the original authors had expressed concerns about the replication designs before data collection; only one of these studies had yielded a statistically significant effect (p <.05). Commenters suggested that lack of adherence to expert review and low-powered tests were the reasons that most of these RP:P studies failed to replicate the original effects. We revised the replication protocols and received formal peer review prior to conducting new replication studies. We administered the RP:P and revised protocols in multiple laboratories (median number of laboratories per original study = 6.5, range = 3–9; median total sample = 1,279.5, range = 276–3,512) for high-powered tests of each original finding with both protocols. Overall, following the preregistered analysis plan, we found that the revised protocols produced effect sizes similar to those of the RP:P protocols (Δr =.002 or.014, depending on analytic approach). The median effect size for the revised protocols (r =.05) was similar to that of the RP:P protocols (r =.04) and the original RP:P replications (r =.11), and smaller than that of the original studies (r =.37). Analysis of the cumulative evidence across the original studies and the corresponding three replication attempts provided very precise estimates of the 10 tested effects and indicated that their effect sizes (median r =.07, range =.00–.15) were 78% smaller, on average, than the original effect sizes (median r =.37, range =.19–.50).
