“…The post-saccadic image may be being antedated, to stitch up the temporal gap induced by saccadic suppression and masking [24,[26][27][28][29]. An active mechanism is implied because chronostasis emerges over and above any time dilation induced in passive control conditions, which simulate the visual effects of a saccade.…”

Several lines of evidence suggest that motoric brain structures may form the core amodal component of a neural network supporting a wide range of timed behaviours. Here, we review recent findings which elucidate the neural computations that occur within motor regions, and in particular the supplementary motor area, in order to support precisely timed actions. Although motor activity may help us represent time, it is also clear that action both enriches and complicates the interpretation of sensory inputs. Hence, in the second half of this review, we also consider the latest findings regarding the perceptual distortions that our actions can impose upon the subjective timeline.3

“…If action-linked changes motor cor in temporal perception were attributed to an adjustment in the rate of an internal clock, the weigh then the magnitude of this effect should also be affected by the duration of the stimulus relative w being judged. However, Yarrow and colleagues have demonstrated that the magnitude of such that the chronostasis effect remains constant across a range of target stimulus durations (Yarrow et al 2004). Thus, it does not appear that actions directly affect the internal representation of time itself.…”

SummaryAnticipation is a hallmark of skilled movements. For example, when removing plates from a loaded tray, the upward force generated by the supporting hand is reduced in anticipation of the reduced load. An adjustment of the postural force occurs as a result of the predicted consequences of the self-initiated action. Although the effect of anticipatory processes is easily discerned in the actions themselves, it is unclear whether these processes also affect our perceptual experience. In this chapter we focus on the relationship between action and the perceptual experience. We begin by reviewing how actions provide reliable predictions of forthcoming sensory information. Following this, we discuss how the anticipation of the time of external events is an important component of action-linked expectations. Finally, we report two experiments that examine how temporal predictions are integrated with the incoming sensory information, evaluating whether this integration occurs in a statistically optimal manner. This predictive process provides the important advantage of compensating for lags in conduction time between peripheral input and the central integration of this information, thus overcoming the physical limitations of sensory channels. Racing against sensory delaysAn important problem for the brain to solve is how to compensate for the temporal gap between when a stimulus is registered by a sensory detector and when it is recognized, either consciously or subconsciously, in the cortex. In humans, such delays happen on the order of hundreds of milliseconds (for review, see Welch & Warren 1986). This slow conduction time can greatly impair how we react to events in our local environment. In many cases, this can mean the difference between smooth, coordinated actions and clumsy gestures.

“…Modulations of the attentional gating of pacemaker outputs to the working memory system or memory processes also have clear predictions regarding timing behavior (Droit-Volet, Clément, & Wearden, 2001;Wearden et al, 1998). More specifically, it has been suggested that more attention paid to time should lead to more pulses being integrated in the clock stage (Zakay & Block, 1995), which in turn code for a longer duration (i.e., dilation of perceived time; Yarrow, Haggard, & Rothwell, 2004). Thus, models such as the STT have consistently proven useful in explaining variations in timing behavior as a result of experimental manipulations.…”

Asymmetrical modulation of time perception by increase versus decrease in coherence of motion

Stimulus properties are known to affect duration judgments. In this study, we tested the effect of motion coherence levels in randomly moving dots on the perceived duration of these stimuli. In Experiments 1 and 2 we tested participants on a temporal reproduction task, using stimuli with varying degrees of motion coherence as the to-be-timed stimuli. Our results in both experiments showed that increasing motion coherence from the encoded (i.e. the first) to the reproduced (i.e. the second) stimulus leads to longer reproduction times. These effects were primarily additive in nature, and their magnitude increased with the difference between the coherence levels in the encoding versus reproduction (decoding) phases. This effect was not mirrored when there was a decrease in motion coherence. Experiment 3 tested if the differential number of exploratory saccadic eye-movements during encoding and reproduction predicted these effects. The behavioral findings of Experiment 1 and 2 were replicated in the third experiment, and the change in the number of eye movements from encoding to reproduction predicted the reproduction time when there was an increase in motion coherence. These results are explained by the effect of attention on the latency to initiate temporal integration that is only manifested when there is an increase in the level of motion coherence.
