Abstract

Combining event-related potential (ERP) with an artificial orthography learning paradigm, this study examined how 7–11-year-old Chinese children from first to fifth grade implicitly acquired orthography-semantics regularities of artificial characters. We manipulated the semantic consistency levels of radicals embedded in artificial characters at high (100 %), moderate (80 %), and low (60 %). The behavioral results indicated that 8-year-olds in the second grade were able to acquire regularities of semantic radicals within a sequence of artificial characters. The ERP results revealed a N170-P300-N400 pattern. The N170 component in the occipitotemporal area indicated orthographic identification during the early stages of learning, while the P300 and N400 components reflected attentional allocation and semantic activation during the later stages of statistical learning of orthography-semantics connections. The interactions between neural activation of statistical learning and grade suggest a significant developmental change in 7-11-year-old children. These findings support the multi-component model of statistical learning and the age-related hypothesis.

正字法语义规律的统计学习：一项发育神经生理学研究

结合事件相关电位（ERP）和人工正字法学习范式，研究了7 - 11岁中国一至五年级儿童人工汉字的正字法语义规则内隐习得情况。我们将人工汉字中嵌入的词根的语义一致性水平控制在高（100 %）、中等（80 %）和低（60 %）。行为结果表明，8岁的二年级儿童能够习得人工汉字序列中语义词根的规律。ERP结果显示N170-P300-N400模式。枕颞区的N170成分反映了早期正字法识别，而P300和N400成分反映了后期正字法-语义连接统计学习的注意分配和语义激活。7-11岁儿童统计学习的神经激活与年级之间的相互作用显示了显著的发展变化。这些发现支持了统计学习的多成分模型和年龄相关假说。

期刊介绍： The journal publishes theoretical and research papers on cognitive brain development, from infancy through childhood and adolescence and into adulthood. It covers neurocognitive development and neurocognitive processing in both typical and atypical development, including social and affective aspects. Appropriate methodologies for the journal include, but are not limited to, functional neuroimaging (fMRI and MEG), electrophysiology (EEG and ERP), NIRS and transcranial magnetic stimulation, as well as other basic neuroscience approaches using cellular and animal models that directly address cognitive brain development, patient studies, case studies, post-mortem studies and pharmacological studies.
