“…For half of the participants, the ring with the gap directed upwards was conditioned neutral and the ring with the gap directed downwards was conditioned negative and vice versa for the other half. Therefore, the experimental procedure excludes that the temporal overestimation effect had been caused by sensory processing stimuli with different physical features like size (Ono & Kawahara, 2007;Thomas & Cantor, 1975;Xuan et al, 2007), position (Aedo-Jury & Pins, 2010;Kliegl & Huckauf, 2014;Long & Beaton, 1981;Roussel et al, 2009) or complexity (Long & Beaton, 1981;Matthews, 2013;Schiffman & Bobko, 1974;Xuan et al, 2007). Consequently, mere differences in the evaluative associations attached to the respective stimuli seem to be sufficient to induce the subjective duration increase irrespective of perceptual differences between emotional and neutral stimuli.…”

“…Furthermore, it is also well known that physical characteristics of visual stimuli like size (Ono & Kawahara, 2007;Thomas & Cantor, 1975;Xuan, Zhang, He, & Chen, 2007), position (Aedo-Jury & Pins, 2010;Kliegl & Huckauf, 2014;Long & Beaton, 1981;Roussel, Grondin, & Killeen, 2009) and complexity (Hicks, Miller, & Kinsbourne, 1976, Long & Beaton, 1981Matthews, 2013;Schiffman & Bobko, 1974;Xuan et al, 2007) influence duration perception, too. For example Xuan and colleagues showed that more complex stimuli, depicting eight or nine dots, were perceived to last longer than visually simpler stimuli, which depicted only one or two dots.…”

It has been found that emotional pictures are estimated to last longer than neutral ones. However, emotional and neutral stimuli often differ in their physical characteristics, too. Since this might also affect time perception, we present a method disentangling a possible confounding regarding the processing of physically different stimulus material. In the evaluative condition paradigm, participants, at first, learnt the association of neutral images with a certain Landolt ring and of emotional images with another Landolt ring with a different gap position. The conditioned Landolt rings were subsequently used in a temporal bisection task. In two experiments, the results revealed a temporal overestimation of Landolt rings conditioned with emotional pictures compared to neutral pictures showing that the temporal overestimation of emotional stimuli cannot be attributed to perceptual differences between neutral and emotional stimuli. The method provides the potential for investigating emotional effects on various perceptual processes.

“…In Experiment 1, we presented stimuli at different locations across the periphery. Previous work has shown that temporal processing is not homogeneous across the visual field (Aedo-Jury & Pins, 2010; Kliegl & Huckauf, 2014), and that speed of temporal processing increases as a function of eccentricity (Carrasco et al., 2003). In agreement with this work, we found that stimuli were reported earlier in the periphery relative to when they were presented centrally.…”

When an Event Is Perceived Depends on Where We Attend

Does the moment when an event is perceived depends on where it is presented? To measure when participants perceived events, they were first familiarized with trial duration, by watching the hand of a clock rotating. Then, the hand was removed, and stimuli were presented at a random time from the trial onset. Participants indicated the location where the hand would have been when the stimulus was presented. The stimuli’s eccentricity, the appearance, and location of the spatial features of the clock were varied. The targets were reported earlier if they were presented in spatial proximity to the clock outline, even when it was not presented during the trial. The effect was replicated with stimuli presented at the same distance from fixation but at different distances from the spatial features. In summary, the time of an event is perceived earlier if it is presented near attended features in the visual scene.

“…As this dependency was not observed for objects rotating at low speeds (i.e. not displaying a compelling rotational motion), it is unlikely that the decrease in perceived duration is due to eccentricity as shown to be the case for static objects 36 37 .…”

Temporal frequency of events rather than speed dilates perceived duration of moving objects

In everyday life moving objects often follow irregular or repetitive trajectories for which distinctive events are potentially noticeable. It is known that the perceived duration of moving objects is distorted, but whether the distortion is due to the temporal frequency of the events or to the speed of the objects remains unclear. Disentangling the contribution of these factors to perceived duration distortions is ecologically relevant: if perceived duration were dependent on speed, it should contract with the distance from the observer to the moving objects. Here, we asked observers to estimate the perceived duration of an object rotating at different speeds and radii and found that perceived duration dilated with temporal frequency of rotations, rather than speed (or perceived speed, which we also measured). We also found that the dilation was larger for two than for one object, but the increase was not large enough to make perceived duration independent of the number of objects when expressed as a function of the local frequency (the number of times an object crossed a given location per time unit). These results suggest that perceived duration of natural stimuli containing distinctive events doesn't depend on the distance of the events to the observer.
