摘要
外语口语焦虑是影响言语互动的重要因素。本研究使用功能性近红外成像超扫描(Hyperscanning)技术,通过两个实验探究了中英双语者在英语和汉语故事叙述任务中,口语焦虑对言语互动双方的行为和大脑活动模式的影响,实验1没有评价性压力,实验2包含评价性压力。两个实验一致发现:(1)英语任务中(相较于汉语)存在更强的口语焦虑,更低的言语互动质量;(2)相较于汉语,英语任务中每对被试左侧缘上回、左侧颞中回和左侧额极的脑间同步性显著减弱;(3)在英语任务中,左侧缘上回的脑间同步性与口语焦虑呈显著负相关、与言语互动质量呈显著正相关,且口语焦虑通过左侧缘上回脑间同步性的部分中介作用影响言语互动质量。本研究的结果表明焦虑情绪对言语互动存在负面的影响,而且这种影响可以通过大脑的同步性得以实现。
Foreign language speaking anxiety is one of the important factors affecting foreign language communication.Fear of negative evaluation is the key factor that induces foreign language speaking anxiety.Many studies have found that foreign language speaking anxiety can negatively affect the quality of verbal interaction through questionnaires and behavioral methods.Yet,few have investigated the brain mechanism of such influence.Therefore,we set up real English communication scene and used fNIRS(functional near-infrared spectroscopy)hyperscanning technique to further investigate relative brain mechanism.A total of 126 Chinese college students were recruited for two experiments.Participants were randomly paired(participant 1 and participant 2)and were asked to finish two storytelling tasks(English vs.Chinese)in turn in both experiments,with fNIRS recording their brain activities simultaneously.Specifically,24 sequentially numbered pictures formed a complete story,participant 1 received pictures with odd numbers,and participants 2 received pictures with even numbers.During the task,one participant would tell the story of the current round,while the other need to listen carefully,and then both of them would complete the foreign language speaking anxiety scale and continued the story.The turn-taking process went on till the end of the story.The interaction quality was evaluated by two experimenter assistants on a seven-point Likert scale.In Experiment 2,participants were informed in advance that they will be evaluated after the task.This is the only difference between the two experiments,which aimed to rise participants’fear of negative evaluation.Through this process,we intended to explore the effect of external evaluation on the degree of foreign language anxiety on behavior and neural levels.Two experiments obtained consistent results:(1)the participants had significant foreign language speaking anxiety in the English task(compared to Chinese),and their verbal interaction quality was also lower;(2)it was found that
