最近的神经影像学研究表明，知觉和概念处理共享一个共同的，特定于模态的神经基板，而模态转换成本的工作表明，他们共享一些相同的注意力机制。在三个实验中，我们采用了模态检测任务，该任务显示模态特定的对象属性（例如，单峰尖锐、暖、深红色或双峰锯齿状、蓬松）进行极短的显示时间，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，听觉的、味觉的、触觉的、嗅觉的、视觉的）。结果表明，知觉和概念处理共享触觉的缺点：人们在检测预期的信息比任何其他形式的触觉不太准确。这些发现支持具身化的主张，即概念系统使用知觉系统的目的表示。我们认为，触觉的劣势出现语言刺激由于内源性注意传入的感官刺激的进化适应。(C)2009爱思唯尔有限公司版权所有。
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. (C) 2009 Elsevier B.V.
