Effects of different speed-accuracy instructions on perception in psychology experiments: evidence from event-related potential and oscillation

HIGHLIGHTS

• What: The third approach focuses on event-related potentials (ERPs), which involve averaging trial EEG data and analyzing event-related oscillations (EROs) in the time-frequency domains based on the ERPs (Başar et_al, 2001). The study examined the evoked components, P100 (P1) and N100 (N1) that occur before 200 milliseconds and are unaffected by the judgment process. The amplitude of alpha band activity increases when attention is focused on external stimuli but decreases when attention is directed inwardly or when eyes are closed. The authors will analyze the evoked event-related oscillations (EROs) in the alpha . . .
