Supplementary Documentation – Interpersonal Distance and Alpha-Band ERSP Modulation

This repository contains supplementary methodological documentation and derived datasets supporting the manuscript examining alpha-band ERSP modulation as a function of interpersonal distance. The experimental design included three interpersonal distances (40 cm, 2 m, 4 m) and two eye conditions (eyes closed, eyes open), with Mask and NoMask conditions. The repository provides: • Channel rejection and independent component exclusion documentation• Epoch rejection quantification and robustness analyses• Repeated-measures ANOVA results and post hoc power analyses• EEGLAB STUDY-based component clustering methodology• Behavioral control analyses (blink amplitude and reaction time) All preprocessing thresholds, clustering parameters, and statistical models are fully documented within the repository. Raw EEG datasets are not included due to file size constraints but are available from the corresponding author upon reasonable request.
