Preprocessed EEG for: Adult-to-infant unidirectional neural coupling mediates selective social learning in infants from the UK and Singapore

Summary: Contains preprocessed EEG data for both adult and infant participants. Detailed EEG preprocessing steps and parameters are described in the paper's method section and supplementary materials. Related code repository: https://github.com/Baby-Linc-Singapore/BABBLE_CODE/ Detailed file descriptions: Preprocessed EEG data files - Each participant-adult pair is stored as a single MATLAB file with naming convention PC/S_BABBLE_AR.mat, where P represents participant ID, C/S indicates site (C for one site, S for another), and AR denotes artifact rejection processing. Each file contains the following key variables: FSamp (200) - Resampling frequency in Hz used for data standardization FamEEGart (3×1 cell) - Adult EEG data organized by repeated block numbers StimEEGart (3×1 cell) - Infant EEG data organized by repeated block numbers Data structure - Each data cell [i] contains block i data, structured as 3 gaze conditions × 3 phrases per block Processing variables - Additional cells (AccEpoch, TotAcceptedEpochs, TotBadEpochs, TotUnattendedEpochs, eplen) contain intermediate preprocessing records and quality metrics that are not required for subsequent analyses
