Two-stage categorization in brand extension evaluation: electrophysiological time course evidence

Area of Science:

• Cognitive Neuroscience
• Consumer Psychology
• Marketing Science

Background:

• Brand names function as mental categories, influencing consumer judgment of new products.
• Similarity-based categorization theory explains how consumers evaluate brand extensions.
• Understanding the cognitive processes behind brand extension evaluation is crucial for marketing strategies.

Purpose of the Study:

• To investigate the neural mechanisms underlying brand extension evaluation.
• To identify distinct cognitive stages in processing brand extensions using event-related potentials (ERPs).
• To differentiate the roles of P2 and N400 brain components in categorization.

Main Methods:

• Employed an event-related potential (ERP) study with two experiments using a prime-probe paradigm.
• Experiment 1 tested in-category, similar-category, and out-of-category brand extensions.
• Experiment 2 utilized subcategory and major-category product names within a related task.

Main Results:

• The P2 component differentiated out-of-category extensions from others, suggesting early-stage processing.
• The N400 component distinguished similar-category from in-category extensions, indicating later-stage processing.
• Experiment 2 showed N400 negativity varied with product category depth, while P2 showed no significant difference.

Conclusions:

• Brand extension evaluation involves a two-stage cognitive process.
• P2 reflects early, low-level, similarity-based processing.
• N400 reflects later, analytic, category-based processing.
