“…The P2 component has been identified in many different cognitive tasks, including selective attention (Hackley, Woldorff, & Hillyard, 1990;Hillyard et al, 1973;Johnson, 1989), stimulus change (Naatanen, 1990), feature detection processes , and short-term memory (Golob & Starr, 2000;Starr & Barrett, 1987). Similar to N1, P2 has been consistently identified by principal components analysis factor scores (Beauducel et al, 2000), baseline-to-peak amplitude (Beauducel et al, 2000;, and latency measures (Segalowitz & Barnes, 1993).…”
