Résumé
We propose an account of comparison asymmetries based on viewing comparison
as a process of structural alignment and mapping . Specifically, we hypothesize that
(1) comparison asymmetries result from directional differences in informativity, and
that (2) asymmetries can therefore be predicted from the relative degree of systematicity
or conceptual coherence of the items being compared . In Experiment 1, we
found a clear preference for placing the more systematic of two passages in the base
position of a comparison . Experiments 1 and 2 further showed that structural alignability
is crucial in obtaining such asymmetries . In Experiment 3, we found that asymmetries
are predicted by the relative systematicity of the comparisons items rather than
by the relative size of the distinctive feature sets . These results are inconsistent with
accounts of asymmetry based on feature contrast or stimulus bias . In Experiments 4
through 6, we tested the functional implications of our account by examining inference
projection and perceived informativity across asymmetric comparisons . Critically,
comparisons having the more systematic item as the base were more likely to result
in inference projection and other forms of target modification and were rated as more
informative than reverse comparisons . We conclude by demonstrating that this account
can explain comparison asymmetries without positing underlying asymmetries in subjective
similarity, and that it offers a unified approach to the directionality of literal
comparisons, analogies, and metaphors .
