“…However, the results found in studies that used a whole-body motion as the non-temporal task (Binetti et al, 2010;Israël et al, 2004;Vercruyssen et al, 1989), as well as the results obtained in the present study, are the opposite of the results predicted by the Attentional Allocation Model. Under a concurrent non-temporal task that involved whole-body motion (passive or active), the participants perceived time as longer rather than shorter, that is, they overestimated physical time.…”

“…Positive acceleration reduced the inter response times (IRTs), negative acceleration increased the IRTs, and no acceleration (no motion or motion at a constant velocity) did not affect time production (see also, . Similar effects were found during rotational motion (e.g., Binetti et al, 2010) and after rotational motion . Israël et al (2004) suggested that time perception was disrupted because their procedure was effectively a dual-task procedure (Zakay, 1993), that is, a procedure in which two tasks were performed simultaneously, one task being the perception of physical displacement and the other task being the production of 1-s intervals.…”

“…In this article we use SET to understand how timing may be affected by motion. Moving stimuli tend to be perceived as longer than static stimuli (see, Kanai et al, 2006;Matthews, 2011) and similar effects occur when it is the participant, instead of the stimulus, that moves (Binetti et al, 2010;Israël et al, 2004;Vercruyssen et al, 1989). Participant whole-body motion can be further subdivided into active or passive according to whether the movements are or are not intentionally produced by the participant.…”

The effect of motion on time perception could be due to the interference of the non-temporal task on the concurrently performed temporal task (e.g., Binetti et al, 2010;Israël et al, 2004;Vercruyssen et al, 1989).…”

To investigate the effect of motion on time perception, participants were asked to perform either a temporal discrimination task or a temporal generalization task while running or standing still on a treadmill. In the temporal discrimination (bisection) task, 10 participants were exposed to two anchor stimuli, a 300-ms Short tone and a 700-ms Long tone, and then classified intermediate durations in terms of their similarity to the anchors. In the temporal generalization task, 10 other participants were exposed to a standard duration (500ms) and then judged whether or not a series of comparison-durations, ranging from 300ms to 700ms, had the same duration as the standard. The results showed that in the temporal bisection task the participants produced more "Long" responses under the dual-task condition (temporal judgments+running) than under the single-task condition (temporal judgments only). In the temporal generalization task, accuracy in the temporal judgments was lower in the dual-task condition than the single-task condition. These results are discussed in the light of dual-task paradigm and of the Scalar Expectancy Theory (SET).

“…The different perception of body rotations during the acceleration and deceleration phases could also be linked to the different effects of these phases on time perception, as reported in several papers (e.g., Israël et al, 2004; Capelli and Israël, 2007; Binetti et al, 2010, 2013). These studies showed that one perceives the time as being faster during body acceleration and as being shorter during deceleration.…”

Several studies have investigated whether vestibular signals can be processed to determine the magnitude of passive body motions. Many of them required subjects to report their perceived displacements offline, i.e., after being submitted to passive displacements. Here, we used a protocol that allowed us to complement these results by asking subjects to report their introspective estimation of their displacement continuously, i.e., during the ongoing body rotation. To this end, participants rotated the handle of a manipulandum around a vertical axis to indicate their perceived change of angular position in space at the same time as they were passively rotated in the dark. The rotation acceleration (Acc) and deceleration (Dec) lasted either 1.5 s (peak of 60°/s2, referred to as being “High”) or 3 s (peak of 33°/s2, referred to as being “Low”). The participants were rotated either counter-clockwise or clockwise, and all combinations of acceleration and deceleration were tested (i.e., AccLow-DecLow; AccLow-DecHigh; AccHigh-DecLow; AccHigh-DecHigh). The participants’ perception of body rotation was assessed by computing the gain, i.e., ratio between the amplitude of the perceived rotations (as measured by the rotating manipulandum’s handle) and the amplitude of the actual chair rotations. The gain was measured at the end of the rotations, and was also computed separately for the acceleration and deceleration phases. Three salient findings resulted from this experiment: (i) the gain was much greater during body acceleration than during body deceleration, (ii) the gain was greater during High compared to Low accelerations and (iii) the gain measured during the deceleration was influenced by the preceding acceleration (i.e., Low or High). These different effects of the angular stimuli on the perception of body motion can be interpreted in relation to the consequences of body acceleration and deceleration on the vestibular system and on higher-order cognitive processes.
