Test instrumental	1041.13_b (41.18)
Experienced noninstrumental reward cue	613.89_c (23.94)

Test noninstrumental	637.68_c (24.99)

n = 15 (one participant’s data excluded as an outlier). Entries that do not share subscripts differ at p < .05 by Tukey’s honestly significant difference; entries that share subscripts do not significantly differ. Differences were calculated on log-transformed RTs; original data are shown for clarity. SEMs are calculated across participants within condition. Only reward cues were shown in Test trials. See Supplementary Figure S1 for full distributions.
