Abstract
The application of electroencephalography (EEG) technology in language research has significantly broadened our understanding of the functional, temporal, and anatomical dimensions of language processing. This paper provides a comprehensive overview of the primary methods employed to analyze EEG data in the context of neurolinguistics, including Event-Related Potentials (ERPs) Component analysis, Time-Frequency (TF) analysis, Topographic analysis, and Connectivity analysis. ERPs offer insights into the timing and sequence of neural events associated with language tasks, while TF analysis sheds light on how different frequency bands are involved in various aspects of language comprehension and production. Topographic analysis maps the spatial distributions of neural activity, and Connectivity analysis explores the interactions between different brain regions during language processing. By leveraging these analytical techniques, researchers can unravel the complex neural mechanisms that facilitate language comprehension and production. Furthermore, this paper critically examines the advantages of EEG, such as its high temporal resolution and non-invasiveness, along with its limitations, including spatial resolution constraints and susceptibility to artifacts. Through this analysis, we aim to highlight the pivotal role of EEG in advancing our understanding of the neural underpinnings of language and discuss future directions for enhancing the methodology and application of EEG in language research.
