| 摘 要： | 该研究利用功能磁共振脑成像(fMRI)技术,比较在新颖语言学习和母语学习过程中大脑皮层参与的异同。实验设置德语学习和汉语学习两个条件,采用跨通道联结学习范式,要求被试在听到听觉词汇后,按键判断屏幕上所呈现的图片是否与所听词汇匹配。行为数据显示,被试在六段实验后基本掌握了德语语音和语义之间的联结关系;脑成像数据显示,两种学习任务都激活了语言加工的主要脑区,而德语词汇学习过程相比汉语参照条件对应的颞叶激活强度与范围有较大的差异,并且比汉语条件表现出更显著的前额叶区域激活。 |

| Abstract: | This study uesd fMRI to examine the brain regions involved in phonological and semantic processing during a novel lexical learning task.Chinese participants who did not know German learned to match spoken German words with pictures.Following presentation of an auditory word,participants would see a picture displayed on the screen and were asked to judge whether or not the picture matched the word and then indicate their response with a button press.A task involving mapping between Chinese words and pictures... |
