Here weassess whether these findings generalize to decisions on self-motion.Participants were presented with whole body yaw rotations of different durations in a 2-Interval-Forced-Choice paradigm, and tasked to discriminate motions on the basis of their amplitude. The corticalhemodynamic response was recorded using functional near-infrared spectroscopy (fNIRS) while partic-ipants were performing the task.The imaging data was used to predict the specific response on individual experimental trials, and topredict whether the comparison stimulus would be judged larger than the reference. Classifier perfor-mance on the former variable was negligible. However, considerable performance was achieved for thelatter variable, specifically using parietal imaging data. The findings provide support for the notion thatactivity in the parietal cortex reflects modality independent decision variables that represent the strengthof the neural evidence in favor of a decision. The results are encouraging for the use of fNIRS as a methodto perform neuroimaging in moving individuals.
