The current thesis focused on multisensory integration during rapid upper-limb movements, specifically at peak limb velocity (PLV). Participants were required to “fling” their limb through a virtual target while aligning PLV with the target. In Experiment 1, participants were provided with augmented: auditory, visual, audiovisual, or no feedback at peak limb velocity. In Experiment 2, participants completed the same flinging task. At PLV, participants were exposed to either two: auditory beeps, visual flashes, or audiovisual events. Participants then indicated which sensory cue was presented first (i.e., left or right of the target) in a within modality temporal order judgment task. This judgment was also made following stimuli presentation at rest. Across both experiments, the results failed to reveal an audiovisual (i.e., bimodal) advantage over unisensory stimuli presentation (i.e., auditory or visual cues alone), suggesting that the optimal integration of audiovisual information may not occur at peak limb velocity. ; M.Sc. |
