摘　　要： “模拟语义学”认为,语言加工涉及感知运动经验的模拟,以往研究在抽象语义加工是否涉及经验模拟这一问题上一直存在争议,其神经机制也不十分明确。本研究采用ERPs脑电技术,考察18名汉语母语者时间词理解对空间判定的启动效应,探究时间语义加工中空间图式的激活及其认知神经机制。研究发现,时间语义加工会引起注意力的空间转移,过去时间引起注意力向左转移,未来时间引起注意力向右转移。一致性条件下(过去/左,未来/右),被试的反应速度更快,80~130毫秒时间窗的P1脑电波幅更大,且主要分布在后枕骨头皮位置。研究没有发现N1波幅的显著变化。P1反映大脑对注意位置目标的关注和控制增强,P1变化表明时间加工激活了通过隐喻映射获得的内隐空间图式,发生空间经验模拟。这一结果支持概念隐喻强势观,时空隐喻神经回路的形成和神经模拟是空间图式激活的根本原因。 Simulated Semantics proposes that there is sensory-motor enactment in concept processing.However, whether sensory-motor experience is involved in abstract concept processing and its neurophysiological correlates remains unclear.An ERP study was carried out to investigate the simulation of spatial schema during the processing of Chinese temporal words.The priming effect of temporal words on spatial judgement task of 18 native Chinese speakers was examined.It was found that processing of time-referenced words primed the spatial locations and shifted attention to the left when cued by the past word, and to the right when cued by the future word.P1 was significantly enhanced in the time window of 80~130 ms for congruent trials, and the effect was typically distributed in occipital sites.No modulation of N1 was found.P1 reflects the enhancement of attention and modulation to targets on attended location, thus it provides neural evidence that perceiving temporal words can activate the implied spatial schema gained from time-space metaphorical mapping and arouse activation of spatial schema.This result supports the strong version of Metaphorical Structuring View, and the activation was elicited by the neural circuit and the simulation of time-space metaphor.
