Although taste and smell seem hard to imagine, some people nevertheless report vivid imagery in these sensory modalities. We investigate whether experts are better able to imagine smells and tastes because they have learned the ability, or whether they are better imaginers in the first place, and so become experts. To test this, we first compared a group of wine experts to yoked novices using a battery of questionnaires. We show for the first time that experts report greater vividness of wine imagery, with no difference in vividness across sensory modalities. In contrast, novices had more vivid color imagery than taste or odor imagery for wines. Experts and novices did not differ on other vividness of imagery measures, suggesting a domain-specific effect of expertise. Critically, in a second study, we followed a group of students commencing a wine course and a group of matched control participants. Students and controls did not differ before the course, but after the wine course students reported more vivid wine imagery. We provide evidence that expertise improves imagery, exemplifying the extent of plasticity of cognition underlying the chemical senses.
尽管味觉和嗅觉似乎难以想象,但有些人仍然报告说在这些感觉模式中有着生动的意象。我们研究了专家是否因为他们已经学会了这种能力,而能够更好地想象气味和味道,或者他们是否首先就是更好的想象者,从而成为专家。为了检验这一点,我们首先使用一系列问卷将一组葡萄酒专家与配对的新手进行了比较。我们首次表明,专家报告了葡萄酒意象更生动,而不同感觉模式之间的生动度没有差异。相比之下,新手对葡萄酒的颜色意象比味觉或嗅觉意象更生动。专家和新手在其他生动意象测量上没有差异,这表明专业知识具有特定领域的影响。至关重要的是,在第二项研究中,我们跟踪了一组开始学习葡萄酒课程的学生和一组匹配的对照组参与者。学生和对照组在课程开始前没有差异,但在葡萄酒课程结束后,学生报告了更多生动的葡萄酒意象。我们提供了专家知识可以提高意象的证据,证明了化学感官背后认知可塑性的程度。
