Individuation of multiple targets during visual enumeration: New insights from electrophysiology

► We assessed the functioning of object individuation during enumeration using ERPs. ► The N2pc was modulated by target numerosity and reached a plateau at 5 items. ► The N2pc asymptote varied according to participants' enumeration capacity. ► Enumeration of small quantities is based on multiple object individuation. ► Individual differences in multiple individuation are related to enumeration skills.
