In-scanner stroop-embedded picture naming task examples. In each pair, the stroop trial, then the picture were presented sequentially on a white background for 1.5 s each, separated by a blank screen for 0.5 s. A variable duration of fixation between pairs (ISI, range = 2.5–16.5 s, average ISI = 4.1 s) was used. Stroop trials in a, c are blue printed in blue, in b, d are brown printed in blue; pictures in a, b are lower lexical competition (H-index: 0.29 ± 0.22), in c, d are higher lexical competition (H-index: 1.35 ± 0.32).
