摘　　要：通过行为与脑电实验技术,比较外语词汇学习过程中,语言符号与知觉符号表征对词汇记忆编码与再认的影响过程,从而考察语义表征对词汇习得的影响机制。行为结果表明,语言符号与知觉符号表征条件下被试对词汇学习效果的主观判断无显著差异,但后者比前者有更高的词汇再认正确率。脑电结果表明,对于词汇编码阶段,相较语言符号表征,知觉符号表征在编码晚期诱发更正的LPC成分;对于词汇再认阶段,知觉符号表征条件诱发更大N400成分,且脑电时频分析表明该条件下出现更为明显的μ波抑制及θ波功率增强现象。研究结果综合表明,与语言符号表征便捷但非模态化的语义加工相比,知觉符号表征加深了词汇晚期编码的深度,并通过知觉模拟,利用多模态信息提高了词汇的形象化再认,从而推动了再认阶段的语义检索,最终内隐性地提高了词汇学习效果。Semantic representation is a way to achieve semantic access,which plays an important role in foreign language vocabulary learning.The linguistic symbolic and perceptual symbolic representations constitute two subsystems of semantic representations.Previous studies have found that the linguistic symbolic representation can provide quick approximate processing,which is suitable for shallow language processing tasks,while the perceptual symbolic representation can create a complete situation model,which is important for deep language processing tasks.In view of these different cognitive processing patterns,the effect of each symbolic representation system on foreign language vocabulary learning were investigated in this study to explore the mechanism of semantic representation on vocabulary learning.A total of 52 participants were randomly assigned to the two symbolic representation conditions and executed a vocabulary learning–recognition task.To manipulate the participants’semantic representations effectively when learning foreign language vocabulary,two types of spatial semantics,i.e.,“up”and“down,”were chosen as the learning materials.Furthermore,to investigate the learning process effectively,the foreign words expressing the meanings of“up”and“down”were selected from languages that the participants were completely unfamiliar with.In the learning stage,Chinese characters or spatial cues of“up”and“down”were presented first as semantic priming stimuli to initiate the participants’linguistic symbolic or perceptual symbolic representations of the foreign words subsequently presented.The participants were then required to learn the foreign words.After every 20 words learned,a test on the semantic recognition of the foreign words was conducted.Behavioral and EEG data were collected to investigate the different effects of linguistic symbolic and perceptual symbolic representations on the learning and recognition stages.The behavioral results showed that no significant difference in judgmen
