A Process-Tracing Study of Brand Extension Evaluation
通过实验室实验，研究品牌延伸评价的认知过程，发现延伸产品与现有产品的相似度（典型性）和品牌现有产品的多样性（品牌宽度）共同影响评价，且典型性与评价过程呈倒U型关系。
The authors explore the implications of considering a brand as representing a category consisting of its products. They report results of a laboratory experiment in which response times and verbal protocols were used to examine processes related to the evaluation of brand extensions. Evaluations of brand extensions were influenced both by the extension's similarity to the brand's current products (brand extension typicality) and by the variation among a brand's current products (brand breadth). An inverted U describes the relationship between brand extension typicality and evaluation process measures. Moderately typical extensions were evaluated in a more piecemeal and less global way than were either extremely typical or extremely atypical extensions. Subjects’ attitudes toward brand extensions were correlated highly with their ratings of brand extension typicality.
