title: Visual discrimination of delayed self-generated movement reveals the temporal limit of proprioceptive-visual intermodal integration.
abstract: This study examined the intermodal integration of visual-proprioceptive feedback via a novel visual discrimination task of delayed self-generated movement. Participants performed a goal-oriented task in which visual feedback was available only via delayed videos displayed on two monitors-each with different delay durations. During task performance, delay duration was varied for one of the videos in the pair relative to a standard delay, which was held constant. Participants were required to identify and use the video with the lesser delay to perform the task. Visual discrimination of the lesser-delayed video was examined under four conditions in which the standard delay was increased for each condition. A temporal limit for proprioceptive-visual intermodal integration of 3-5s was revealed by subjects' inability to reliably discriminate video pairs.
