The Effect of Package Shape on Consumers' Judgments of Product Volume: Attention as a Mental Contaminant
通过系列实验发现，包装形状会影响消费者对产品容量的判断，吸引更多注意力的形状会让消费者认为容量更大，这种注意力导致的“心理污染”偏差在多种情境下存在，且习惯化或厌恶内容可减弱该效应。
A series of experiments examined how a container's shape can bias judgments of product quantity. Packages that have shapes that are perceived as attracting more attention are also perceived to contain a greater volume of a product than same-sized packages that attract less attention. The disparity in attention leads to “mental contamination” of the volume judgment. The bias holds for different sets of containers, for containers placed in different contexts, and for containers with contents varying in desirability. Habituation to an unusual container that attracts attention can reduce the effect, as can viewing containers with a disliked content.
