“…Indeed, in the variable FP conditions, BPs decreased monotonically as relative FP length (measured as FP rank) increased. This is consistent with the results from the previous studies on the subject of FP effects on time perception (Gamache et al, 2011;Grondin & Rammsayer, 2003;Mo & George, 1977) and on RT (Niemi & Näätänen, 1981;Requin, Granjon, Durup, & Reynard, 1973). Also, the magnitude of that decrease was significantly larger for the 900-ms FP range conditions than for the 150-ms and 300-ms ones.…”

“…Looking at the FP effect on time perception from the perspective of temporal preparation, it could be said that the core findings in the literature regarding the variable FP effect mostly pertain to the effect of posterior temporal uncertainty on perceived duration, i.e., on the effect of the relative FP lengths on perceived duration (Gamache et al, 2011;Grondin & Rammsayer, 2003;Mo & George, 1977). Some of these studies did identify factors influencing the FP effect that can be construed as modulators of prior temporal uncertainty.…”

“…Mo and George (1977) gave the participants information about the FP by associating each possible FP with tones of different pitches. Gamache et al (2011) manipulated prior information about the FP in a similar manner by informing or not that the FPs were variable. The participants in the constant FP group who were falsely led to believe that the FP would be variable showed a consistent pattern of temporal underestimation compared with those that were given no prior information.…”

“…As with simple RT experiments following the same variable FP paradigm, the participants' temporal preparation increases as FP elapses. Recent successful replications of the variable FP effect on time perception have attested the robustness of this empirical effect as well as the significance of the temporal preparation explanation (Bendixen, Grimm, & Schröger, 2005;Gamache, Grondin, & Zakay, 2011;Grondin & Rammsayer, 2003;Los & Horoufchin, 2011). This type of manipulation also has been used for studying time-order judgments (Bausenhart, Rolke, & Ulrich, 2008).…”

“…We used the same general experimental design as Grondin and Rammsayer (2003) and Gamache et al (2011), i.e., a task in which participants are asked to judge whether a given temporal interval delimited by two tones is shorter or longer than a 100-ms standard interval. It should be noted that, in this kind of experimental design, the participants' subjective duration of the target intervals is measured by the bisection point (BP).…”

One factor influencing the perceived duration of a brief interval is the length of the period preceding it, namely the foreperiod (FP). When multiple FPs are varied randomly within a testing session, longer FPs result in longer perceived duration. The purpose of this study was to identify what characteristics modulate this effect. In a task where participants were asked to categorize the duration of target intervals with respect to a 100-ms standard, the FPs were distributed over a 150-, 300-, or 900-ms range with the midpoint (1000 ms) of these distributions being kept constant. The results indicate that the effect of the length of variable FPs on perceived duration was much stronger in the 900-ms range condition. More specifically, this effect is due to the differences between the shortest FPs. The results also reveal that, overall, there are more short responses in the 300-ms condition than in the other range conditions. Moreover, the data reveal that the narrower the distribution, the better the discrimination. One interpretation of the main result (range effect) is that a wider distribution leads to an increased prior uncertainty towards the foreperiod length.

Effects of social information on duration perception by different mechanisms in sub‐ and supra‐second range: Evidence from face features

et al. 2021

Human faces convey abundant social information. The influence of social information on duration estimation was examined by comparing a cartoon face (CF; social) condition with geometric plane figures, or CFs with internal elements disturbed from their normal position (non-social) condition, and also by comparing a human portrait facing the front (more social interaction) condition with the portrait facing the back (less social interaction) condition. Results showed that in the supra-second range, both CFs and human portraits facing the front led to an underestimation compared with non-social or less social information conditions. In the sub-second range, only portraits facing the front were overestimated compared with those facing the back and with the CFs. These results suggest that in the millisecond range, the biological information conveyed by faces may lead to higher arousal, which may result in accelerated clock speed and overestimation. In the supra-second range, it is possible that attention was diverted by social information, resulting in duration underestimation. Taken together, our results suggest that the different mechanisms were involved in duration perception of social information conveyed by face feature in the sub-and supra-second range.

Like other senses, our perception of time is not veridical, but rather, is modulated by changes in environmental context. Anecdotal experiences suggest that emotions can be powerful modulators of time perception; nevertheless, the functional and neural mechanisms underlying emotion-induced temporal distortions remain unclear. Widely accepted pacemaker-accumulator models of time perception suggest that changes in arousal and attention have unique influences on temporal judgments and contribute to emotional distortions of time perception. However, such models conflict with current views of arousal and attention suggesting that current models of time perception do not adequately explain the variability in emotion-induced temporal distortions. Instead, findings provide support for a new perspective of emotion-induced temporal distortions that emphasizes both the unique and interactive influences of arousal and attention on time perception over time. Using this framework, we discuss plausible functional and neural mechanisms of emotion-induced temporal distortions and how these temporal distortions may have important implications for our understanding of how emotions modulate our perceptual experiences in service of adaptive responding to biologically relevant stimuli.
