“…However, to date, this possibility has not been demonstrated yet, although some works have proven that visualizing a whole body motion e.g. 11121314 or the execution of an action prior a visual stimulation e.g 15. can alter subjective time.…”

Several studies have shown that the observation of a rapidly moving stimulus dilates our perception of time. However, this effect appears to be at odds with the fact that our interactions both with environment and with each other are temporally accurate. This work exploits this paradox to investigate whether the temporal accuracy of visual motion uses motor representations of actions. To this aim, the stimuli were a dot moving with kinematics belonging or not to the human motor repertoire and displayed at different velocities. Participants had to replicate its duration with two tasks differing in the underlying motor plan. Results show that independently of the task's motor plan, the temporal accuracy and precision depend on the correspondence between the stimulus' kinematics and the observer's motor competencies. Our data suggest that the temporal mechanism of visual motion exploits a temporal visuomotor representation tuned by the motor knowledge of human actions.

“…For instance, when estimating the time of exposure of images portraying different dance body positions, individuals perceived a longer duration for those images that implied a greater amount of movement dynamics and vice versa. This suggests that an internal simulation of the implied action sequence influenced perceivers’ sense of temporal duration [5]–[6]. Interestingly, individuals showed higher accuracy in temporal duration discrimination for photographs representing athletes in active postures than the same athletes portrayed in a quiet standing position [4].…”

The estimation of the time of exposure of a picture portraying an action increases as a function of the amount of movement implied in the action represented. This effect suggests that the perceiver creates an internal embodiment of the action observed as if internally simulating the entire movement sequence. Little is known however about the timing accuracy of these internal action simulations, specifically whether they are affected by the level of familiarity and experience that the observer has of the action. In this study we asked professional pianists to reproduce different durations of exposure (shorter or longer than one second) of visual displays both specific (a hand in piano-playing action) and non-specific to their domain of expertise (a hand in finger-thumb opposition and scrambled-pixels) and compared their performance with non-pianists. Pianists outperformed non-pianists independently of the time of exposure of the stimuli; remarkably the group difference was particularly magnified by the pianists’ enhanced accuracy and stability only when observing the hand in the act of playing the piano. These results for the first time provide evidence that through musical training, pianists create a selective and self-determined dynamic internal representation of an observed movement that allows them to estimate precisely its temporal duration.

“…Most of previous studies addressing effects of movement on time perception have used geometric shapes moving across a computer screen as their primary stimuli. However, static and dynamic representations of the human body can also generate temporal distortions [16,17]. Apparent biological motion, particularly regarding the shape of the human body, is thought to induce specific distortions in time perception [18][19][20][21][22][23].…”

“…Apparent biological motion, particularly regarding the shape of the human body, is thought to induce specific distortions in time perception [18][19][20][21][22][23]. Nather and Bueno suggested that the perceived duration of symmetrical representations of the human body (sculptures) tended to be temporally underestimated compared to asymmetrical body sculptures [16]. According to the authors, asymmetric figures implicitly suggest a larger amount of movement, as they require larger and longer actions to reestablish the body balance compared to symmetrical figures.…”

Visual motion stimuli can sometimes distort our perception of time. This effect is dependent on the apparent speed of the moving stimulus, where faster stimuli are usually perceived lasting longer than slower stimuli. Although it has been shown that neural and cognitive processing of biological motion stimuli differ from non-biological motion stimuli, no study has yet investigated whether perceived durations of biological stimuli differ from non-biological stimuli across different speeds. Here, a prospective temporal reproduction task was used to assess that question. Biological motion stimuli consisted in a human silhouette running in place. Nonbiological motion stimuli consisted in a rectangle moving in a pendular way. Amount and plausibility of movement for each stimulus and frame-rate (speed) were evaluated by an independent group of participants. Although amount of movement was positively correlated to frame rate, movie clips involving biological motion stimuli were judged to last longer than nonbiological motion stimuli only at frame rates in which movement was rated as plausible. These results suggest that plausible representations of biomechanical movement induce additional temporal distortions to those modulated by increases in stimulus speed. Moreover, most studies that have reported neural and cognitive differences in the processing of biological and nonbiological motion stimuli acquired neurophysiological data using fMRI. The present study aimed additionally to report differences in the processing of biological and non-biological motion stimuli across different speeds using functional near infrared spectroscopy (fNIRS), a less costly and portable form of neurophysiological data acquisition.
