“…Polarity differences have often been discussed as an alternative explanation for metaphor congruency effects (e.g., Pecher, Van Dantzig, Boot, Zanolie, & Huber, 2010;Schubert, 2005;Ulrich & Maienborn, 2010;Vallesi et al, 2008;Van Dantzig, Zeelenberg, & Pecher, 2009;Weger & Pratt, 2008), but whether polarity differences can explain previously observed metaphor congruency effects has never been examined. Given that most studies have examined how concepts are structured in vertical space (see Landau, Meier, & Keefer, 2010), this article examines the mechanisms through which the vertical position of stimuli influence the speed with which abstract bi-polar concepts are categorized.…”
