Response times of intensity and hedonic comparisons were determined in a within-subjects experimental design. Forced-choice paired comparisons of orange lemonades with various concentrations of added quinine sulfate were made by 48 subjects. Depending on experimental condition, the subjects had to focus either on intensity or on pleasantness and give their responses as fast as possible. The data showed shorter response times for intensity comparisons than for pleasantness comparisons. Although taste processing may be partially serial and partially parallel, the larger part of the response times and the differences between them may be due to cognitive processing.
在一项被试内实验设计中确定了强度和享乐比较的反应时间。48名受试者对添加了不同浓度硫酸奎宁的橙子柠檬汁进行了强制选择配对比较。根据实验条件，受试者必须专注于强度或愉悦度，并尽快给出他们的反应。数据显示，强度比较的反应时间比愉悦度比较的反应时间短。尽管味觉处理可能部分是串行的，部分是并行的，但反应时间的大部分以及它们之间的差异可能归因于认知处理。
