Sense Of Time

With this cross-sectional study we investigated how individual differences regarding present- and future-oriented mental processes are related to the experience of time in the seconds and minutes range. A sample of students (N = 100) filled out self-report measures of time perspective (ZTPI), mindfulness (FMI), impulsiveness (BIS), and the daydreaming frequency scale (DDFS). Furthermore they were asked to (a) retrospectively judge the duration of a waiting period of five minutes, and (b) to prospectively perform an visual duration reproduction task with intervals of 3, 6, and 9 seconds. Regression models show that (a) being more present fatalistic (ZTPI) and more impulsive are related to longer duration estimates of the waiting period, and (b) having a stronger propensity to daydream leads to a stronger under-reproduction of temporal intervals. These findings show how personality traits related to present orientation are associated with the state-like perception of duration.

Temporal Judgments

We recently proposed that systematic underreproduction of time is caused by a general judgment bias towards earlier responses, instead of reflecting a genuine misperception of temporal intervals. Here we tested whether this bias can be explained by the uncertainty associated with temporal judgments. We applied transcranial magnetic stimulation (TMS) to inhibit neuronal processes in the right posterior parietal cortex (PPC) and tested its effects on time discrimination and reproduction tasks. The results show increased certainty for discriminative time judgments after PPC inhibition. They suggest that the right PPC plays an inhibitory role for time perception, possibly by mediating the multisensory integration between temporal stimuli and other quantities. Importantly, this increased judgment certainty had no influence on the degree of temporal underreproduction. We conclude that the systematic underreproduction of time is not caused by uncertainty for temporal judgments.
