at occipito-parietal electrode sites (P1, P2, PO3, PO4, Pz and POz) and quantified between 300 and 500 ms. The CNV, a late negative-going wave for active-attention cues, was detected within a central ROI (C1, C2 and Cz) between 700 and 1500 ms (earliest onset of the target). Consistent with earlier studies (Broyd et al., 2012; Connor and Lang, 1969; Goldstein et al., 2006; Jonkman et al., 2003) this large time window was divided in two parts: 700–1100 ms and 1100–1500 ms, resulting in an early and late CNV component.
