Abstract

En 中文

• Low-Gf adolescents show larger P3 amplitudes across three core executive function tasks. • Aperiodic offset modulation is enhanced in high-Gf adolescents during inhibitory control. • Neural efficiency differences localize to late-stage cognitive resource allocation. • Integrated ERP and aperiodic analyses reveal multi-layered neural profiles of Gf.
