Sugar is often used in learning and conditioning studies as an unconditioned stimulus (US) to enhance liking for a flavor mixed with it. To use sugar as a US, participants are selected only if they like the taste of sugar based on their ratings of a sweetened water US during a preexposure trial prior to experimental procedures. This US-only trail introduces a potential sensory bias and can lead to participant attrition when such a trial is conducted the day prior to experimental procedures. The aim of the present study was to construct a brief scale, called the Estimated Daily Intake Scale for Sugar (EDIS-S), to measure a participant's exposure to sugar in their diet. It was hypothesized that exposure to sugar would be positively correlated with liking for sugar. As expected, an 11-item EDIS-S was reliable and significantly correlated with ratings of liking for a sweetened taste solution. Implications for the use of the EDIS-S as an assessment in many areas of research, and as a participant selection tool for conditioning studies are discussed.
糖通常被用作学习和条件作用研究中的无条件刺激（US），以增强对与它混合的味道的喜好。为了将糖用作 US，只有在参与者根据预先暴露试验中对加糖水 US 的评分喜欢糖的味道时，才选择他们参加实验程序。这个只有 US 的试验引入了一种潜在的感官偏见，并且当在实验程序前一天进行这样的试验时，可能会导致参与者流失。本研究的目的是构建一个简短的量表，称为糖的估计每日摄入量量表（EDIS-S），以测量参与者饮食中糖的摄入量。研究假设糖的摄入量与对糖的喜好呈正相关。正如预期的那样，一个 11 项的 EDIS-S 是可靠的，并且与对加糖味道溶液的喜好评分显著相关。讨论了 EDIS-S 在许多研究领域的评估中的应用，以及作为条件作用研究的参与者选择工具的意义。
