Prior studies of subjective passage of time experience have focused on the effects of high level emotional or cognitive aspects of activities and situations. However, what defines and constitutes the subjective experience of the passage of time as a unique category of time experience remains poorly understood 8– 10. This is also reflected in changes of the experience of passage of time as described by patients with depressive syndromes 3– 6 and mild cognitive impairments 7, even when their ability to judge durations is preserved. In fact, we are aware of this difference and seem to have accepted this decoupling of the experienced subjective passage of time from the ongoing physical time as measured by clocks 1, 2. However, everyday experience suggests that this is not how we subjectively experience the passage of time: We refer to time passing by “slowly” when feeling bored or to time “flying” when being engaged in a pleasant activity. as performed by physical clocks, structure our everyday life and enable us to coordinate our actions with others over long distances and long periods, based on the fundamental assumptions that physical time passes by with the same velocity and that it can be reliably measured with clocks. Potential mechanisms behind these results and the prospects of experimental approaches towards passage of time experience in psychological and neuroscientific research are discussed. The results strongly suggest differential psychological processes underlying the experience of time passing by and the ability to estimate time durations. Results from two experiments show that velocity and density of stars in the starfield affect passage of time experience independent from duration estimation and the color tracking task: the experienced passage of time is accelerated with higher rates of moment-to-moment changes in the starfield while duration estimations are comparably unaffected. We introduce a new paradigm in a starfield environment that allows to study the effects of basic visual aspects of a scene (velocity and density of stars in the starfield) and the duration of the situation, both embedded in a color tracking task. Here, we tested the influence of low-level visual stimuli on the experience of passage and duration of time in 10–30 s intervals. However, our understanding of the factors contributing to passage of time experience has been mostly restricted to associated emotional and cognitive experiences in temporally extended situations. The other problem I had was that I wanted the text to start blank and scroll into the screen.The experience of passage of time is assumed to be a constitutive component of our subjective phenomenal experience and our everyday life that is detached from the estimation of time durations. Also, you have to make sure you have an end time set, otherwise it just flickers. So, you have to put a negative sign in front of the formula for it to scroll the other way. The original formula posted above scrolls the The next word to read would come from the right (as if you were actually reading text). So if you keep your eyes in the middle of the screen I wanted my text to scroll from right to left. You might find performance issues (jittering motion) if you try to render a lot of text in one go, in which case you may have to switch to using images of text. frameN here refers to the number of frames shown so far, and you can extend the formula to produce what you need. In essence, you can enter an arbitrary formula in the position field and the stimulus will be-redrawn at a new position on each frame. Push the Run button and your text will move from left to right, at one pixel per screen refresh, but stay at a fixed y-coordinate. And select “set every frame” in the popup button next to that field.
