EEG recordings from 19 participants performing a P300-based brain-computer interface paradigm, designed to assess how visual stimulus properties affect evoked responses and classification accuracy. Each participant completed three sessions with varying numbers of stimuli (4 to 9) and two flash types, a standard flash and a superimposed cartoon face. Data were recorded from eight scalp electrodes (Fz, Cz, P3, Pz, P4, PO7, PO8, Oz) at 256 Hz, with markers encoding experimental phases and activated symbols.
