与属性词相关的感知模式，如闪烁或点击，先前已被证明会影响随后的属性验证判断（Pecher等人，）。这一发现被称为概念模态转换效应，它支持了这样一种说法，即大脑的感知和行动系统有助于促进概念的表征。本研究通过记录事件相关电位（ERPs）来探讨这种效应的认知和神经基础，参与者在关键试验中进行了视觉或听觉属性的属性验证任务。我们发现，对于视觉属性验证，模态切换与振幅N400增加相关。对于听觉验证，切换导致了一个更大的后期积极复杂。观察到的通道转换的ERP效应表明属性词进入知觉脑系统。此外，时间和模式的影响表明，知觉系统的影响，在验证的听觉属性的决策阶段，在验证的视觉属性的语义阶段。
The perceptual modalities associated with property words, such as flicker or click, have previously been demonstrated to affect subsequent property verification judgments (Pecher et al.,). Known as the conceptual modality switch effect, this finding supports the claim that brain systems for perception and action help subserve the representation of concepts. The present study addressed the cognitive and neural substrate of this effect by recording event-related potentials (ERPs) as participants performed a property verification task with visual or auditory properties in key trials. We found that for visual property verifications, modality switching was associated with an increased amplitude N400. For auditory verifications, switching led to a larger late positive complex. Observed ERP effects of modality switching suggest property words access perceptual brain systems. Moreover, the timing and pattern of the effects suggest perceptual systems impact the decision-making stage in the verification of auditory properties, and the semantic stage in the verification of visual properties.
