Abstract: | Utilizing the case‐based reminding theory in analogical reasoning, this research proposes that the evaluation of a brand extension can be improved by reminding consumers of a similar brand in the extension category. This effect is derived from a brand‐to‐brand similarity, in addition to the product‐to‐product and brand‐to‐product similarity identified in prior literature. Experiment 1 explores the idea that the effect of similar case reminders is most pronounced in moderately similar extensions than in highly similar or highly dissimilar extensions due to schema congruity. Experiments 2 and 3 distinguish the levels of similarity (i.e., product‐to‐product, brand‐to‐product, and brand‐to‐brand similarity) as a source of consumers' evaluations on a brand extension and further eliminate an alternative explanation of instantaneous learning in the advertisement setup of Experiment 1. © 2010 Wiley Periodicals, Inc. |
