Neural correlates of concreteness effect in semantic processing of single Chinese characters using mixed-effects modeling

This study examined the ERP correlates of concreteness effects on single Chinese characters of different form classes, including nouns, verbs and adjectives, in a go/no-go semantic categorization task. Diverging from previous works, the current study employed a non-factorial design and focused on semantic processing of single characters representing a spectrum of concreteness values to ensure high ecological validity. The results of linear mixed-effects modeling showed that concreteness modulated N400 amplitudes elicited by monomorphemic nouns and verbs in posterior regions, similar to previous studies examining compound words. Concreteness continued to modulate neural response to verbs in the same pattern as in the N400 during 500-1000 ms. The absence of a sustained frontal negativity was proposed to be due to the use of single character stimuli and a lack of explicit contrast in concreteness across stimuli that did not encourage imagery processing. The opposite forms of manifestation of the concreteness effects on the two major form classes were attributed to task requirements

Early event-related potentials differences in orthographic processing of native and non-native Chinese readers

Efficient Chinese character reading requires rapid access to orthographic representations of radical form and position. This study identified the temporal sequence of radical form, radical position and lexicality processing in adult first language (L1) and intermediate second language (L2) Chinese readers. Event-related potential responses in a one-back repetition detection task were submitted to linear mixed-effects models. Violation of radical position produced P100 effects that were left-lateralized for L1 readers and right-lateralized for L2 readers. When controlling for P100 activation, radical position produced a left-lateralized effect at the N170 for L2 readers but no additional activities for L1 readers. Radical form effects were found at the N270 for L1 readers, where radical form violation produced larger N270. Results suggested that radical representations are position-specific in initial orthographic processing for both groups. However, different temporal dynamics and topographic distributions suggested divergent radical processing for native versus non-native readers from the beginning
