**Data** Raw data can be found in the Experimental Data folder. R code used to process the data and prepare it for further analysis is included. Diffusion model parameters were estimated using fast-dm-30 (see https://www.psychologie.uni-heidelberg.de/ae/meth/fast-dm/). The control file used for modeling (exp1) and parameter estimates for each participant (Drift Diffusion Parameters) can also be found in the data folder. Estimated model parameters were used to predict RTs. Cumulative distribution functions of the predictive RT are overlaid those of the measured RT for each participant in the CDFs file. TOJ stimuli were presented at the participant's previously determined threshold level. We have included staircase data for each participant in the Staircase Data folder. **Materials** The E-Prime code used to control the presentation of the stimuli is included in Materials. The staircase procedure was adapted from Hairston and Malidijian (2008) *Computer Methods and Programmes in Biomedicine*. The audio files include the TOJ stimuli and each stimulation condition. These must be included in the folder with the E-Prime code to run the experiment
