 Active training. The investigators will use adaptive training tailored to each individuals thresholds. Specifically, a two-alternative forced-choice TOJ task will be used, where participants will be presented with an auditory beep 1000 Hz pure tone presented at 75 dB and a visual flash a white circle presented on grey background with varying stimulus onset asynchronies SOAs and will be asked to judge the temporal order of the stimulus pair. On each training day, the investigators will establish the range of SOAs for individuals based on their thresholds determined from the pre-training TOJ assessment given on the same day. The maximum SOA will be 0.2 log units greater than their estimated threshold and will be used for both visual leading positive SOA and auditory leading negative SOA stimuli. Participants will be exposed to a total of 160 trials in the training phase 8 SOAs x 20 repetitions. Feedback will be provided after each response.
