This research examines how comparison of objects underlies free categorization, an essential component of human cognition. Previous results using our binomial labeling task have shown that classification probabilities are affected in a graded manner as a function of similarity, i.e., the number of features shared by two objects. In a similarity rating task, people also rated objects sharing more features as more similar. However, the effect of matching features was approximately linear in the similarity task, but superadditive (exponential) in the labeling task. We hypothesize that this difference is due to the fact that people must select specific objects to …

The widespread availability of online word of mouth (WOM) enables modern consumers to assess not only the opinions of others about products and services, but also the extent to which those opinions are consistent or dispersive. Despite longstanding calls for greater understanding of mixed opinions, existing evidence is inconclusive regarding effects of WOM dispersion, and theoretical accounts have relied primarily on the notion of reference dependence. Extending prior work, this research proposes an attribution-based account, in which consumer interpretation of WOM dispersion depends on the extent to which tastes in a product domain are perceived to be dissimilar, so that …
