Theories of grounded cognition propose that modal simulations underlie cognitive representation of concepts [Barsalou, L. W. (1999). Perceptual symbol systems. Behavioral and Brain Sciences, 22(4), 577-660; Barsalou, L. W. (2008). Grounded cognition. Annual Review of Psychology, 59, 617-645]. Based on recent evidence of modality-specific resources in perception, we hypothesized that verifying properties of concepts encoded in different modalities are hindered more by perceptual short-term memory load to the same versus different sensory modality as that used to process the property. We manipulated load to visual and auditory modalities by having participants store one or three items in short-term memory during property verification. In the high (but not low) load condition, property verification took longer when the property (e.g., yellow) involved the same modality as that used by the memory load (e.g., pictures). Interestingly, similar interference effects were obtained on the conceptual verification and on the memory task. These findings provide direct support for the view that conceptual processing relies on simulation in modality-specific systems.
具身认知理论认为，模态模拟是概念认知表征的基础[巴萨卢，L.W.（1999年）。知觉符号系统。《行为与脑科学》，22(4)，577 - 660；巴萨卢，L.W.（2008年）。具身认知。《心理学年度评论》，59，617 - 645]。基于近期关于知觉中特定模态资源的证据，我们假设，与用于处理属性的感官模态相同而非不同时，知觉短期记忆负荷对验证不同模态编码概念的属性造成的阻碍更大。我们通过让参与者在属性验证过程中将一或三个项目存储在短期记忆中，来操纵视觉和听觉模态的负荷。在高（而非低）负荷条件下，当属性（如黄色）与记忆负荷所使用的模态（如图像）相同时，属性验证花费的时间更长。有趣的是，在概念验证和记忆任务上也获得了类似的干扰效应。这些发现为概念加工依赖于特定模态系统中的模拟这一观点提供了直接支持。
