Product Discrimination Studies

Changes to products in terms of ingredients or manufacturing processes are sometimes necessary for cost or productivity reasons.  At the same time, protecting a product franchise for established brands is essential in today’s marketplace.  To ensure required changes can be implemented with no detectable difference in the finished product, discrimination testing is often the chosen methodology.

Spencer Research has developed and documented procedures for several models of discrimination tests, including, but not limited to:

• Triangle Tests
• Same/Different Tests
• Duo/Trio Tests
• Repeat Pairs Tests

Regardless of the model chosen, qualified category or brand specific respondents are selected, allowing us to identify detectable differences across a broad array of product categories.
