Abstract:
The effects of response bias, cognitive strategy change and the sequence of tasting are discussed in relation to the triangle test. Theoretical approaches like Thurstonian modelling and Sequential Sensitivity Analysis are reviewed. It is concluded that the triangle test is prone to many pitfalls; even a slight change in the instructions can bring about a radical change in performance.
