经典的语义记忆理论假设概念是在一个单一的非模态记忆系统中表征的。在挑战这一经典观点时，纯模态理论或混合模态理论提出概念表征植根于感觉运动脑区，该区域通常处理感觉和动作相关信息。虽然神经影像学研究提供了证据的感觉或动作相关功能的概念处理和感觉运动脑系统之间的功能解剖联系，有人认为，这种感觉运动激活的方面可能不直接反映概念处理，而是战略图像或概念后的阐述。在本ERP研究中，我们调查了掩蔽效应的声学和动作相关的概念特征，以探讨无意识的自动概念加工隔离。在额中央电极处观察到阈下特征特异性ERP效应，其在极性、地形和潜在脑电源方面有所不同，与有意识观看条件下的早期发现一致。这些研究结果表明，概念的声音和动作表征也可以无意识地访问，从而排除任何postconceptual战略过程。因此，本研究进一步证实了行动和知觉的概念和语义加工的基础。
Classical theories of semantic memory assume that concepts are represented in a unitary amodal memory system. In challenging this classical view, pure or hybrid modality-specific theories propose that conceptual representations are grounded in the sensory–motor brain areas, which typically process sensory and action-related information. Although neuroimaging studies provided evidence for a functional–anatomical link between conceptual processing of sensory or action-related features and the sensory–motor brain systems, it has been argued that aspects of such sensory–motor activation may not directly reflect conceptual processing but rather strategic imagery or postconceptual elaboration. In the present ERP study, we investigated masked effects of acoustic and action-related conceptual features to probe unconscious automatic conceptual processing in isolation. Subliminal feature-specific ERP effects at frontocentral electrodes were observed, which differed with regard to polarity, topography, and underlying brain electrical sources in congruency with earlier findings under conscious viewing conditions. These findings suggest that conceptual acoustic and action representations can also be unconsciously accessed, thereby excluding any postconceptual strategic processes. This study therefore further substantiates a grounding of conceptual and semantic processing in action and perception.
