LAPELC² / RESEARCH / ELECTROENCEPHALOGRAPHY

Electroencephalography

We investigate neural activity associated with language processing using electroencephalography (EEG) and event-related potentials (ERPs).

How it
work?

Neural recording

We use high-density EEG to record electrical brain activity while participants perform language tasks.

Signal processing

Signals are preprocessed to address artifacts and extract time-resolved measures, including event-related potentials (ERPs) and neural oscillations.

Analysis and interpretation

We analyze neural response patterns to investigate cognitive processes involved in language perception, comprehension, and production.

What can EEG contribute?

Language comprehension and production

Investigating neural processes involved in reading, listening to, and producing sentences.

Perception and prosody

Studying speech perception, prosody, and the integration of linguistic and paralinguistic information.

Development and diverse populations

Research with children, adults, and clinical populations to understand individual differences and developmental trajectories.

Audiovisual integration

Studying the integration of auditory and visual information in speech perception.

Integration
with other
measures.

EEG can be combined with behavioral measures and eye tracking to provide a more comprehensive understanding of the cognitive processes underlying language.
