Abstract

Visual word recognition is crucial for improving reading skills in second language learners (L2Ls). It is unclear whether L2Ls who are native speakers of languages that use alphabetic scripts can recognize Chinese characters at an early stage of visual processing and if their visual specialization can reach a level of word recognition comparable to that of native Chinese speakers. This study aims to uncover the visual specialization mechanism of Chinese L2Ls. A delayed-color matching task was carried out with participants who were Chinese first language speakers (L1Ss) and advanced Chinese L2Ls with Indonesian as their first language. The results of the event-related potentials (ERPs) indicated that L2Ls exhibited significant visual specialization with a predominant distribution of the left-lateralized N170, along with some activation in the right hemisphere. These findings suggest that the early processing stage of Chinese characters by advanced L2Ls is similar to that of adult native speakers, although it is still influenced by their first language and its writing system.

左侧化N170对高级汉语学习者视觉特化的影响

视觉认字对于提高第二语言学习者（L2Ls）的阅读能力至关重要。母语为字母文字的第二语言学习者能否在视觉加工的早期阶段识别汉字，他们的视觉特化能否达到与母语为汉语的学习者相媲美的文字识别水平，目前尚不清楚。本研究旨在揭示汉语第二语言学习者的视觉特化机制。研究人员对第一语言为汉语的被试和第一语言为印尼语的高级汉语第二语言被试进行了延迟颜色匹配任务。事件相关电位（ERPs）的结果表明，L2Ls表现出明显的视觉特化，主要分布在左侧的N170，右半球也有一些激活。这些研究结果表明，后进生对汉字的早期加工阶段与成年母语使用者相似，但仍受到母语及其书写系统的影响。

期刊介绍： Frontiers in Human Neuroscience is a first-tier electronic journal devoted to understanding the brain mechanisms supporting cognitive and social behavior in humans, and how these mechanisms might be altered in disease states. The last 25 years have seen an explosive growth in both the methods and the theoretical constructs available to study the human brain. Advances in electrophysiological, neuroimaging, neuropsychological, psychophysical, neuropharmacological and computational approaches have provided key insights into the mechanisms of a broad range of human behaviors in both health and disease. Work in human neuroscience ranges from the cognitive domain, including areas such as memory, attention, language and perception to the social domain, with this last subject addressing topics, such as interpersonal interactions, social discourse and emotional regulation. How these processes unfold during development, mature in adulthood and often decline in aging, and how they are altered in a host of developmental, neurological and psychiatric disorders, has become increasingly amenable to human neuroscience research approaches. Work in human neuroscience has influenced many areas of inquiry ranging from social and cognitive psychology to economics, law and public policy. Accordingly, our journal will provide a forum for human research spanning all areas of human cognitive, social, developmental and translational neuroscience using any research approach.
