Time-dependent integration of prospective and retrospective contributions to intention reports. (a) Reaction time distribution (EMG onset) with respect to the time of cue presentation in RP+ (top) and RP− (bottom) trials. Bars show the grand averages and SEMs of trial counts in 100 ms bins, respectively. The distributions for individual participants are shown in electronic supplementary material, figure S9. (b) Probability of responding ‘yes’ (intention present) after Go cues for RP+ and RP− trials individually (colour coded) and for different reaction times. Probability estimates and 95% confidence intervals are calculated by pooling data across participants and are reported according to reaction times in 4 bins of 250 ms. While the main text reports grand averages, the pooled data shown here more accurately represent the results of the mixed-model analysis. (c) Model predictions are generated for a continuous reaction time variable. Shown are the grand averages across participants (SEM shown as shaded area). The probabilities estimated for individual participants are shown in electronic supplementary material, figure S10.
