TL;DR: This first demonstration of causality reversing perceived temporal order cannot be explained by postperceptual distortion, lapsed attention, or saccades.
Abstract: The goal of perception is to infer the most plausible source of sensory stimulation. Unisensory perception of temporal order, however, appears to require no inference, because the order of events can be uniquely determined from the order in which sensory signals arrive. Here, we demonstrate a novel perceptual illusion that casts doubt on this intuition: In three experiments (N = 607), the experienced event timings were determined by causality in real time. Adult participants viewed a simple three-item sequence, ACB, which is typically remembered as ABC in line with principles of causality. When asked to indicate the time at which events B and C occurred, participants’ points of subjective simultaneity shifted so that the assumed cause B appeared earlier and the assumed effect C later, despite participants’ full attention and repeated viewings. This first demonstration of causality reversing perceived temporal order cannot be explained by postperceptual distortion, lapsed attention, or saccades.

TL;DR: The hypothesis presented here is that there is a biological corollary to relativity theory, postulated that biological time perception is related by an inverse relationship between the velocities of neural processing events and perceived elapsing time.

TL;DR: These results demonstrate that loss of SSEPs is associated with a delay in perceptual awareness, consistent with the hypotheses that the SSEP acts as a marker for cortical events important for perceptual timing.
Abstract: Objective To determine if patients with brain lesions who have a unilateral loss of their primary somatosensory-evoked potential (SSEP) have altered temporal perception. Background Benjamin Libet postulated that the neural processing of stimuli to reach the conscious awareness takes 300 to 500 milliseconds and that accurate temporal perception of stimulus onset requires a retroactive computation. Although Libet proposed that the primary SSEP acts as a timing marker for this backward referral of perceived stimulus onset time, there has not been a systematic study of the necessity of the primary SSEP for perceptual timing. Methods Participants were 10 healthy older adults and 10 stroke patients with hemisensory deficits. SSEPs were recorded from each hemisphere using median nerve stimulation. The participants' temporal perception of sensory stimuli was determined by asking them the temporal order of bilateral hand stimuli over varying interstimulus intervals. Results Patients with unilateral loss of SSEPs had a significantly greater mean delay in perception of stimuli from their contralesional arm than participants with intact bilateral SSEPs [mean delay (+/-standard deviation): 134 (+/-142) msec vs. 2.5 (+/-13) msec; P=0.03]. Conclusions These results demonstrate that loss of SSEP is associated with a delay in perceptual awareness. This observation is consistent with the hypotheses that the SSEP acts as a marker for cortical events important for perceptual timing.
