a Set-Go task schematic. In auditory and visual blocks of trials, participants were asked to respond as fast as possible to the Go cue, generating a reaction time (RT). In auditory blocks of trials, white noise bursts of 50 ms duration served as Set and Go cues; in visual blocks of trials, checker boards of 50 ms duration served as cues (Methods). b In separate blocks of trials, the time between Set and Go (Go time) was drawn from a truncated exponential distribution (Exp) or from its left-right flipped version (Flip). c Histogram of RT pooled across the 23 participants and all experimental conditions. d Reciprocal probabilistically blurred PDF fits mean auditory RT over Go time (Methods). e Reciprocal probabilistically blurred PDF fits mean visual RT. f Mirrored temporally blurred HR (Methods) does not capture auditory RT. g Mirrored temporally blurred HR does not capture visual RT. d–g For plotting, RTs and fit curves were smoothed by reducing the Go time step size from 16 to 32 ms. Shaded areas represent s.e.m. across participants. Source data are provided as a Source Data file.
