Recent neuroimaging research has shown that perceptual and conceptual processing share a common, modality-specific neural substrate, while work on modality switching costs suggests that they share some of the same attentional mechanisms. In three experiments, we employed a modality detection task that displayed modality-specific object properties (e.g., unimodal shrill, warm, crimson, or bimodal jagged, fluffy) for extremely short display times and asked participants to judge whether each property corresponded to a particular target modality (e.g., auditory, gustatory, tactile, olfactory, visual). Results show that perceptual and conceptual processing share a tactile disadvantage: people are less accurate in detecting expected information regarding the sense of touch than any other modality. These findings support embodied assertions that the conceptual system uses the perceptual system for the purposes of representation. We suggest that the tactile disadvantage emerges for linguistic stimuli due to the evolutionary adaptation of endogenous attention to incoming sensory stimuli.
最近的神经影像学研究表明，感知和概念处理共享一个共同的、特定于模态的神经基础，而关于模态转换成本的研究表明，它们共享一些相同的注意机制。在三项实验中，我们采用了一种模态检测任务，该任务在极短的显示时间内显示特定于模态的物体属性（例如，单模态刺耳、温暖、猩红或双模态锯齿状、蓬松），并要求参与者判断每个属性是否对应于特定的目标模态（例如，听觉、味觉、触觉、嗅觉、视觉）。结果表明，感知和概念处理共享触觉劣势：人们在检测与触觉相关的预期信息时的准确性不如其他任何模态。这些发现支持了具身认知的观点，即概念系统使用感知系统进行表示。我们认为，由于内源性注意对传入感觉刺激的进化适应，触觉劣势出现在语言刺激中。
