The utility of the same-different protocol when studying very fatiguing products (Dijon style mustard), as well as when inspecting consumers' abilities to discriminate among food products, was confirmed. The stabilizing effect of a familiarization procedure on the t criterion variations in the same-different test was investigated. Using an independent samples design, and the triangle procedure as a control, this effect was indeed observed. Furthermore, the same-different protocol yielded a higher d' value than the triangle test, confirming its higher sensitivity. Sensory fatigue, rather than memory, appeared to be the reason for this higher sensitivity.
