Differences In Activation Processing Of Chinese And English Emotional Words Under Face-word Stroop Task

The differences in the activation of emotional information in bilingual vocabulary reveal the interaction between language and emotion.A large number of studies show that for early bilinguals,there is almost no difference in the activation of emotional information in bilingual vocabulary;for late bilinguals with unbalanced development,the activation of emotional information in the first language is stronger than that in the second language;and there is a consensus on the factors that affect the activation of bilingual emotional information,such as the frequency of second language use,familiarity and acquisition environment.Over the years,the emotional conflict paradigm provides a new way to explore the automatic activation of lexical emotional information,while the research on the differences of emotional information activation of bilingual vocabulary compared with this paradigm is relatively lacking.Based on the existing research,this study uses the emotional conflict paradigm to explore the differences in the activation of bilingual vocabulary emotional information by Chinese English learners through two experiments,and to explore the influence of the time of vocabulary presentation on the differences.On this basis,ERPs experimental technology is used to provide evidence of neural mechanism.In experiment one,we set different SOA to compare the difference of emotional information activation of bilingual vocabulary and explore the influence of SOA on the difference;in experiment two,we exclude the influence of emotional information of faces on the early activation of emotional information of vocabulary,and explore the neural mechanism of the difference of emotional information activation of bilingual vocabulary when SOA is 300 ms.Research results and conclusions:(1)When SOA is 0ms,Chinese EFL learners respond more quickly to emotional conflict tasks when vocabulary and face valence are the same,and the Stroop effect of the first language is significantly greater than that of the second language.This result indicates that Chinese EFL learners' emotional information is activated to a certain extent in emotional conflict tasks,which has an impact on face recognition,and the activation of emotional information in the first language is stronger than that in the second language.(2)When SOA is 300 ms,Chinese EFL learners respond faster when the valence of words and faces are the same than when they are not.There is no significant difference between the Stroop effect of the first language and the second language.The results show that the emotional information of Chinese EFL learners has an impact on the recognition of facial holes when the words are activated to a certain extent,and the time of vocabulary presentation can affect the activation of bilingual words of Chinese EFL learners.(3)In the early time window(260-350ms),the average amplitude of EPN induced by emotional words in the first language was significantly larger than that of emotional words in the second language.The results show that the emotional information of the first language is more automatic than that of the second language when the irrelevant stimuli are excluded.(4)In the late time window(350-550ms),the average amplitude ratio of N450 induced by vocabulary and face valence inconsistency was larger than that induced by the first language vocabulary and face valence inconsistency,and there was no difference between them.This result shows that inconsistent conditions induce more emotional conflicts than consistent conditions,and emotional words in the first language hinder face recognition more than those in the second language,that is,emotional information in the first language is more active than that in the second language.(5)In the late time window(650-850ms),there is no difference in the average amplitude of LPC induced by bilingual emotional words,which shows that the emotional information of bilingual words has been analyzed and evaluated correspondingly;while in the specific brain area,the average amplitude of LPC induced by the consistency of second language vocabulary and face valence is larger than that induced by the inconsistency,which shows that the emotional information of the second language vocabulary is in a long time range It also triggered the psychological expectation of the subjects.
