The Impact of Feedback on the Different Time Courses of Multisensory Temporal Recalibration

Figure 1

(a) Representation of a trial sequence for the simultaneity judgment (SJ) task. Participants were asked to judge if stimuli occurred at the same time or different times. (b) Individual fittings for a single participant using the sliding-window approach across Trials 1–860. The inset on the left shows a single fitting at one time-point along the time course with the PSS (mean of distribution) and TBW (standard deviation of distribution) at that particular moment in time. The TBW, PSS (cumulative) and ΔTBW, ΔPSS (rapid) were normalized on a within-subject basis, and in order to correct for multiple comparisons we consider an effect significant at α < 0.01 for at least 10 consecutive trials. Trial 0 was defined as the 140 trials utilized to establish initial estimates of the PSS and TBW. The time course analysis was conducted on the following 860 trials. From Trials 1–720, participants were assigned to one of four groups that received varying amounts of feedback following a response. From Trials 721–860, no feedback was presented following a response for all participants.
