观察到了水果饮料的甜度和砂纸的估计触感粗糙度的上下文变化。中等刺激在较强项目的背景下被判断为不那么强烈，而在较弱项目的背景下被认为更强烈，这是一种对比效应。参考标准的使用减少了用于标记的震级刻度BUR或用于震级估计的对比度偏移的大小。
Contextual shifts were observed for sweetness of a fruit beverage and for estimated tactile roughness of sandpapers. Midrange stimuli were judged to be less intense in the context of stronger items and more intense in the context of weaker items, a contrast effect. The use of a reference standard decreased the size of the contrast shift for the labeled magnitude scale bur nor for magnitude estimation.
