Using Economic Incentives to Distinguish Perception Bias from Discrimination Ability in Taste Tests
研究提出用经济激励让受试者暴露真实感知能力、减少猜测，从而在口味测试中同时测出产品差异、受试者自认的辨别能力及其感知偏差。
Taste test are commonly used to determine if participants can detect a difference between products; however, any test is subject to guessing and a perception bias by the participants. The authors use economic incentives to induce subjects to reveal their perceived tasting abilities and minimize their guessing. The method provides three additional pieces of information: (1) a test of the differences between the products, (2) a measure of the subject's perceived discrimination ability, and (3) a measure of the subject's perception bias with respect to his or her true discrimination ability.
