抽象动词的具身表征:运动特征的影响

The Embodied Representation of Abstract Verbs:The Effect of Motor Features

本研究使用具身行为范式—动作-句子相符效应(ACE)探讨了动词运动特征在抽象动词具身表征中的作用。实验1验证ACE在考察感觉运动系统参与双音节动词表征问题上的可行性,结果在具体动词中得到了ACE。实验2以不同运动特征值的抽象动词为材料,在高运动抽象动词中得到了ACE,但在低运动抽象动词中未发现ACE,且ACE大小与运动特征评分显著相关。结果证明了感觉运动系统在抽象动词表征中的参与,支持抽象概念的具身表征观点。

The way in which abstract concepts are represented has been discussed more intensely because of the emergence of the embodied cognition.According to the embodied theories,cognition is fully grounded in the body,and human concepts are“rooted”in perception,action and emotion systems.Accumulating evidence suggests that concrete concepts are closely linked to sensorimotor system,whereas studies on the role of the sensorimotor system for abstract words have not come to an agreement.The present study addresses the issue of whether the abstract concepts,specifically abstract verbs,are embodied or grounded in sensorimotor system.In most of the previous studies,abstract concepts have been considered as an unitary whole,which neglect the fact that different abstract words are linked to sensorimotor experiences differently.We thus hypothesize that it is the various proportion of the sensorimotor features in the abstract word stimuli that may explain the inconsistent results.Here we performed two behavioral experiments to test our hypothesis.The Action-sentence Compatibility Effect,the typical and powerful evidence of embodied theory,is adopted to indicate the involvement of sensorimotor system in semantic processing.In both experiments,participants were required to judge the word a verb or not.Experiment 1 investigated the ACE of the concrete and abstract verbs(e.g.,“投掷”/“抛弃”),with the aim of examining whether individual two-syllable Chinese action verbs were processed through mental simulation.The repeated measurement design of 2(action verbs types:concrete/abstract verbs)×2(action congruency:the direction of the verbs and the required movement are congruent/incongruent)was adopted.Forty-five participants volunteered in this study.Experiment 2 further classified the abstract verbs into two types according to the proportion ratings of the motor feature,and investigated the ACE of high and low motion abstract verbs(e.g.,“承受”/“流露”),in order to elaborate the influence of motor features in the verbs on the sensorimotor representation of abstract concepts.The repeated measurement design of 2(abstract verbs types:high/low motion abstract verbs)×2(action congruency:the direction of the verbs and the required movement are congruent/incongruent)was adopted.Forty-nine participants volunteered in this study.Results showed that ACE was only observed in the concrete verbs processing of experiment 1(p<.05),and in the high motion abstract verbs processing of experiment 2(p<.05),but not in the low motion abstract verbs(p>.05).That is,when the direction of the verbs and the required movement were congruent(i.e.,both were toward or away from the participant),the reaction time of semantic judgement was significantly faster.Furthermore,in the experiment 2 the correlation analysis indicated the proportion ratings of the motor feature was significantly correlated to the magnitude of the ACE(i.e.,difference between reaction times for incongruent and congruent trials)(r=.461,p<.001).In conclusion,the findings demonstrate that a role of motor system in semantic processing is not restricted to concrete words but extends to at least the abstract verbs in which the proportion of the motor feature is high.Specifically,the results suggest that(1)ACE is present in the two-syllable Chinese action verbs,so verbs are processed through sensorimotor simulation.and(2)motor system plays a role in the abstract verbs processing,yet the proportion of the motor feature in the verbs could affect the involvement of motor system.Overall,the present study supports the embodied representation views indicating that sensorimotor system is involved in the abstract concept processing and sensorimotor features in the abstract words do matter a lot.
