Twenty adults performed a modified Eriksen flanker task while recording occipital steady-state visually evoked potentials (SSVEPs). Across all intensities, 10 Hz flickers yielded SSVEPs approximately three times larger than 30 Hz, confirming its efficacy in alpha entrainment. At the behavioral level, alpha stimulation selectively reduced flanker interference – without evidence of a uniform suppression of flanker processing – compared to 30 Hz stimulation. Importantly, stimulus design had a marked impact on user comfort: the ricker flicker elicited reliable alpha-band entrainment while being rated as the most comfortable.
