“…It is noteworthy that while the direction of the PSS shifts observed after lag-adaptation to A200V was consistent with seminal reports on temporal recalibration (Fujisaki et al, 2004;Vroomen et al, 2004), the PSS following V200A lag-adaptation did not shift in the direction predicted by seminal temporal recalibration effects. Nevertheless, the latter finding remains consistent with other lag-adaptation reports (Miyazaki et al, 2006;Yamamoto et al, 2012) and major differences in experimental design including the choice of task and the absence of readapting trials in the TOJ assessment task could account for these differences (Cai et al, 2012;Yamamoto et al, 2012).…”

“…Shifts in perceived AV simultaneity following lag-adaptation (Fujisaki et al, 2004;Miyazaki et al, 2006;Vroomen et al, 2004;Yamamoto et al, 2012) have been hypothesized to originate from mechanisms capable of adjusting the neural processing time across sensory modalities (Fujisaki et al, 2004;Moutoussis and Zeki, 1997;Stone et al, 2001;Sugita and Suzuki, 2003;Zeki and Bartels, 1998). In support of this hypothesis, our study reveals that such mechanisms may be implemented as phase shifts of neural oscillations: contrasting the sensory responses before and after AV lag-adaptation provided no evidence for a latency code hypothesis and instead revealed significant phase shifts of the entrained 1 Hz neural oscillations.…”

“…To test the specific hypothesis that the phase of an entrained neural oscillation directly informs on the variability of conscious timing, we transiently shifted participants' perceived timing using a lagadaptation paradigm (Fujisaki et al, 2004;Miyazaki et al, 2006;Vroomen et al, 2004). Fig.…”

a b s t r a c t a r t i c l e i n f oTime perception is a critical component of conscious experience. To be in synchrony with the environment, the brain must deal not only with differences in the speed of light and sound but also with its computational and neural transmission delays. Here, we asked whether the brain could actively compensate for temporal delays by changing its processing time. Specifically, can changes in neural timing or in the phase of neural oscillation index perceived timing? For this, a lag-adaptation paradigm was used to manipulate participants' perceived audiovisual (AV) simultaneity of events while they were recorded with magnetoencephalography (MEG). Desynchronized AV stimuli were presented rhythmically to elicit a robust 1 Hz frequency-tagging of auditory and visual cortical responses. As participants' perception of AV simultaneity shifted, systematic changes in the phase of entrained neural oscillations were observed. This suggests that neural entrainment is not a passive response and that the entrained neural oscillation shifts in time. Crucially, our results indicate that shifts in neural timing in auditory cortices linearly map participants' perceived AV simultaneity. To our knowledge, these results provide the first mechanistic evidence for active neural compensation in the encoding of sensory event timing in support of the emergence of time awareness.

“…The most common methods require that participants report either the order of two events (a temporal order judgement; TOJ) or whether two or more events occurred synchronously or asynchronously (a simultaneity judgement; SJ). Intriguingly, when brief auditory and visual stimuli are repeatedly presented slightly out of synch during a period of adaptation, participants subsequently change their judgements in these tasks, consistent with their having developed a new opinion about the most synchronous relationship (Fujisaki, Shimojo, Kashino, & Nishida, 2004;Vroomen, Keetels, de Gelder, & Bertelson, 2004). This effect is known as temporal recalibration.…”

This is the unspecified version of the paper.This version of the publication may differ from the final published version. Permanent repository link AbstractDeciding precisely when we have acted is challenging, as actions involve a train of neural events spread across both space and time. Repeated delays between actions and consequent events can result in a shift, such that immediate feedback can seem to precede the causative act. Here we examined which neurocognitive representations are affected during such sensorimotor temporal recalibration, by testing if the effect generalises across limbs, and whether it might reflect altered decision criteria for temporal judgements. Hand or foot adaptation phases were interspersed with simultaneity judgements about actions involving the same or opposite limb. Shifts in the distribution of participants' simultaneity responses were quantified using a detection-theoretic model, where a shift of both boundaries together gives a stronger indication that the effect is not simply a result of decision bias. By demonstrating that temporal recalibration occurs in the foot as well as the hand, we confirmed that it is a robust motor phenomenon:Both low and high boundaries shifted reliably in the same-limb conditions. However, in cross-limb conditions only the high boundary shifted reliably. These two patterns are interpreted to reflect a genuine change in how the time of action is represented, and a timing criterion shift, respectively.Keywords: Temporal recalibration, temporal judgement, adaptation, synchrony, action 4 Consider a falling apple. Our subjective experience of this well-known prompt for scientific insight is seamless and unified; the apple appears to fall as a coherent composite of colour, form and motion, before striking the ground with a dull thud. However, from the perspective of a homunculus (or indeed a neuroscientist) looking down upon the brain's activity in response to this sequence of events, the view is of a time-smeared and spatially distributed cacophony of electro-chemical signalling. This viewpoint leaves us wondering how the observer is able to decide with confidence that this particular auditory thud occurred at the same time as that particular visual collision.Science has not yet provided a compelling answer to this question. There is, however, evidence to suggest that recent experience plays an important role, or, put another way, that the temporal relationships that constitute simultaneity can be learnt and relearnt. Several methods exist to try and establish the relative time at which two events appear maximally synchronous (known as the point of subjective simultaneity or PSS). The most common methods require that participants report either the order of two events (a temporal order judgement; TOJ) or whether two or more events occurred synchronously or asynchronously (a simultaneity judgement; SJ). Intriguingly, when brief auditory and visual stimuli are repeatedly presented slightly out of synch during a period of adaptation, participants subsequen...

“…The effects of attention and 'prior entry'-more attention allocated to the first stimulus-may play important roles in the evaluation of the TOT (for review, see Spence et al 2001). Context and prior experience, even if short, also affect the TOT: in a recalibration paradigm, adaptation to intersensory or sensorimotor desynchrony widens the window of tolerance and lowers the precision of order perception under various types of stimulations ( Fujisaki et al 2004;Vroomen et al 2004;Navarra et al 2005;Stetson et al 2006;Vatakis et al 2007;Hanson et al 2008).…”

How long did it take you to read this sentence? Chances are your response is a ball park estimate and its value depends on how fast you have scanned the text, how prepared you have been for this question, perhaps your mood or how much attention you have paid to these words. Time perception is here addressed in three sections. The first section summarizes theoretical difficulties in time perception research, specifically those pertaining to the representation of time and temporal processing. The second section reviews non-exhaustively temporal effects in multisensory perception. Sensory modalities interact in temporal judgement tasks, suggesting that (i) at some level of sensory analysis, the temporal properties across senses can be integrated in building a time percept and (ii) the representational format across senses is compatible for establishing such a percept. In the last section, a two-step analysis of temporal properties is sketched out. In the first step, it is proposed that temporal properties are automatically encoded at early stages of sensory analysis, thus providing the raw material for the building of a time percept; in the second step, time representations become available to perception through attentional gating of the raw temporal representations and via re-encoding into abstract representations.
