“…Our results are consistent with the previous study in Turkish subjects, in which the P300 amplitude was significantly larger in the ney (their ethical music) background than in cello (foreign music) background, and the topography of the P300 response indicated a relatively higher participation of frontal areas during hearing ney [1] . The amplitude of P300 generally was interpreted as the reflection of selective attention and memory updating process [17] , thus our experiment confirmed the inference that cultural familiar music had positive effects on selective attention and memory updating process, especially in frontal areas. The specialization of brain hemispheres for processing cultural familiar music in Chinese subjects is demonstrated by their right hemisphere lateralization.…”

“…LPC is the representation in working memory and was proved to relate to syntax and semantic processing [4,9,[11][12][13]17] , thus we infer that guqin music has positive effects on syntax and semantic processing in the right anterior-temporal area in Chinese subjects. On the other hand, two previous studies found that larger long-lasting positivity was caused by Thai tone [16] and Chinese music [15] .…”

Differential cognitive responses to guqin music and piano music in Chinese subjects: an event-related potential study

Objective To compare the cognitive effects of guqin (the oldest Chinese instrument) music and piano music. Methods Behavioral and event-related potential (ERP) data in a standard two-stimulus auditory oddball task were recorded and analyzed. Results This study replicated the previous results of culture-familiar music effect on Chinese subjects: the greater P300 amplitude in frontal areas in a culture-familiar music environment. At the same time, the difference between guqin music and piano music was observed in N1 and later positive complex (LPC: including P300 and P500): a relatively higher participation of right anterior-temporal areas in Chinese subjects. Conclusion The results suggest that the special features of ERP responses to guqin music are the outcome of Chinese tonal language environments given the similarity between Guqin's tones and Mandarin lexical tones.

“…Most ERP research on N2 is not about language materials but usually associated with non-linguistic factors such as perceptual mismatch, attention, control and inhibition [48,49]. Different from them, the N200 reported here is hard to be attributed to these factors as it was present in one script but not in others.…”

Centro-parietal N200: An event-related potential component specific to Chinese visual word recognition

Almost all written languages currently used in the world are alphabetic or phonologically-based scripts (e.g., English) whose word recognition involves discrimination of one-dimensional linear combinations of several dozens of letters or phonological units, except written Chinese whose vocabulary consists of a large number of block characters, the analysis of which relies on the extraction of 2-dimensional form information at multiple levels including radical, character, and multiple-character word. Whether the dramatic contrast between the 2 types of orthography leads to distinctive mental processes is a fundamental question in psycholinguistic research unanswered in the past three decades. Using event-related potentials and visual lexical decision tasks, we asked native Chinese speakers to discriminate between real Chinese words and pseudo-or non-words and observed a widespread negative deflection with centro-parietal focus elicited 200 ms post-stimulus onset. This N200 response showed a clear and large amplitude enhancement upon word repetition and seems to be specific to Chinese as no similar effects had been reported in word recognition studies involving alphabetic scripts under similar experimental conditions. Further evidence showed that this N200 could not be attributed to non-linguistic sensori-perceptual processes, nor phonological or semantic processes, but likely reflects very early identification of the orthography of individual words involving extensive and higher-level visual analysis. Recently the first author proposed a meaning-spelling theory of written Chinese vocabulary proposing that the Chinese and alphabetic scripts are the only 2 possible logical types of mature human writing systems, and that the former is more thoroughly a visual language compared with the latter and thus shall emphasize more of visual processing. Reinforcing each other, the meaning-spelling theory and the discovery of the centro-parietal N200 reveal the uniqueness of Chinese both theoretically and empirically, and provide strong arguments for the intrinsic distinction between written Chinese and alphabetic scripts.

“…Furthermore, there is an attentionrelated ERP, the N2-posterior-contralateral (N2pc), which is typically observed in the N2 time window at posterior scalp sites that are contralateral to the position of a potential target item on which attention is focused (Patel and Azzam 2005). The N2a that is elicited by deviant auditory stimuli, attended or unattended, is referred to as mismatch negativity (MMN; for a review, see Naatanen et al 2012).…”

Event-Related Brain Potentials in the Study of Inhibition: Cognitive Control, Source Localization and Age-Related Modulations

In the previous fifteen years, a variety of experimental paradigms and methods have been employed to study inhibition. In the current review, we analyze studies that have used the high temporal resolution of the event-related potential (ERP) technique to identify the temporal course of inhibition to understand the various processes that contribute to inhibition. ERP studies with a focus on normal aging are specifically analyzed because they contribute to a deeper understanding of inhibition. Three time windows are proposed to organize the ERP data collected using inhibition paradigms: the 200 ms period following stimulus onset; the period between 200 and 400 ms after stimulus onset; and the period between 400 and 800 ms after stimulus onset. In the first 200 ms, ERP inhibition research has primarily focused on N1 and P1 as the ERP components associated with inhibition. The inhibitory processing in the second time window has been associated with the N2 and P3 ERP components. Finally, in the third time window, inhibition has primarily been associated with the N400 and N450 ERP components. Source localization studies are analyzed to examine 2 the association between the inhibition processes that are indexed by the ERP components and their functional brain areas. Inhibition can be organized in a complex functional structure that is not constrained to a specific time point but, rather, extends its activity through different time windows. This review characterizes inhibition as a set of processes rather than a unitary process.
