Research On The Cognitive Mechanism Of Virtual Reality Environment Affecting New Language Learnin

Based on the virtual reality technology,previous studies have preliminarily explored language learning and found that virtual reality technology is an important tool for promoting new language learning.However,previous findings are mainly based on language learning in native English speakers,and it is unclear whether the effect of virtual reality on new language learning will s also applicable to China’s education system.This paper is based on the CAMIL theory,with the aid of event related potential(ERP)technology,and with traditional picture-word matching learning as a reference.At the same time,this study also focuses on the potential role of cognitive individual differences in immersive new language learning.The first study revised 147 objects from a Dutch database,which covers a set of standardized 3-D objects for virtual and augmented reality research and application.Finally,the first study retained and obtained H value,naming consistency,representation consistency,visual complexity and familiarity of 147 3-D objects.Combined with the standards of previous studies,133 3D objects were retained and the relevant indicators were analyzed.The results indicated that there was a significant negative correlation between H value and naming consistency,and a significant positive correlation between image consistency and naming consistency,indicating that the database is also suitable for Chinese cultural background.Based on the revised 3D database in the first study,in the second study,we constructed a highly interactive learning scenario with immersive virtual reality technology and explored the impact of the learning environment on new language learning in terms of behavioral performance and neural mechanisms.Participants in the second study were asked to learn German word in virtual reality environment and traditional picture-word matching learning condition,respectively.Then,a translation task was carried to test the learning effect,while their behavioral and EEG results were recorded during the process.The behavioral results show that the word learning performance in the virtual reality environment is significantly better than the traditional picture-word matching condition,as indicated by faster reaction time(RT)and higher accuracy(ACC).Combined with the ERP results,the advantage of new language learning in virtual reality environment is mainly reflected in the P200 component,which was manifested by the larger P200 amplitude caused by virtual reality environment compared with the traditional environment.In addition,in order to explore the relationship between new language learning and individual cognitive ability in a virtual reality environment,the Flanker task was used to test the inhibition,alertness and orientation of the participants,and the correlation between the Flanker task and the new language translation task indicators was analyzed.The results showed that P200 components were significantly correlated with inhibition and alertness,suggesting that the influence of virtual reality environment on new language learning is related to individual cognitive ability.This may be because the high-load characteristics of virtual reality environment activate the participation of inhibition and alertnessIn conclusion,this study revealed the cognitive mechanism of virtual reality environment that affects adults’ new language learning,and also found the important role of learning environment in foreign language vocabulary learning,which supports CAMIL model.It provided a new idea for foreign language education reform,and also provided a foundation for the organic combination of virtual reality technology and foreign language education.
