Average across subjects for the early (M250) and late (M550) components for lag 1 and control conditions, time locked to T2. Seen trials were split according to the speed of RT1. Trials where RT1 was smaller than the first quartile was classified as fast (blue line) and trials above the third quartile were classified as slow (red line). Blinked and Control trials are represented in green and black respectively. Over the group, the M250 was time locked to the onset of the stimulus and larger for slow versus fast RT1, while the M550 was delayed for slow versus fast RT1 trials. Bar plots on the right represent the group averaged peak latency and duration of the M250 (upper part) and the M550 (lower part) for seen trials in lag 1 condition. Each bar represent a quartile of RT1 from fast (blue) to slow (red) reaction times. An ANOVA with RT1 quartiles as a within-subject factor revealed a significant effect on the duration of the M250 but not on its latency. It was the opposite for the M550: a significant effect was observed on the latency but not on the duration.
