30 Sep 2015TL;DR: In this paper, the authors examined whether the duration of two successive short sounds can affect the perception of the time interval marked by the onsets of these sounds, and found that the effects of marker duration were summarized as follows: 1) Lengthening both the first and the second marker clearly causes the interval to be judged longer, 2) lengthening the first marker tends to cause the interval for longer, and 3) also tends to lead to the interval being judged longer.
Abstract: We examined whether the duration of two successive short sounds can affect the perception of the time interval marked by the onsets of these sounds. An experiment was conducted using marker durations of 20 to 100 ms and inter-onset time intervals of 120, 240, and 360 ms. The effects of marker duration were summarized as follows: 1) Lengthening both the first and the second marker clearly causes the interval to be judged longer, 2) Lengthening the first marker tends to cause the interval to be judged longer, and 3) Lengthening the second marker also tends to cause the interval to be judged longer.

TL;DR: In this paper, the authors used a novel approach, requiring rapid intuitive, 9ensemble9 averaging of a whole set of time intervals, to probe the subjective timeline, which revealed subjective averaging to be close to the geometric mean, indicative of a logarithmic timeline underlying time perception.
Abstract: Although time perception is based on the internal representation of time, whether the subjective timeline is scaled linearly or logarithmically remains an open issue. Evidence from previous research is mixed: while the classical internal-clock model assumes a linear scale with scalar variability, there is evidence that logarithmic timing provides a better fit to behavioral data. A major challenge for investigating the nature of the internal scale is that the retrieval process required for time judgments may involve a remapping of the subjective time back to the objective scale, complicating any direct interpretation of behavioral findings. Here, we used a novel approach, requiring rapid intuitive, 9ensemble9 averaging of a whole set of time intervals, to probe the subjective timeline. Specifically, observers9 task was to average a series of successively presented, auditory or visual, intervals in the time range 300-1300 ms. Importantly, the intervals were taken from three sets of durations, which were distributed such that the arithmetic mean (from the linear scale) and the geometric mean (from the logarithmic scale) were clearly distinguishable. Consistently across the three sets and the two presentation modalities, our results revealed subjective averaging to be close to the geometric mean, indicative of a logarithmic timeline underlying time perception.

TL;DR: In this article , an auditory temporal generalization (TG) task in the range of 400 ms was used to compare event-related potentials (ERPs) with findings from an analogous task using standard durations of 200 ms, and it was concluded that the P300 span may denote the transition between time perception and time estimation.
Abstract: There has been a long-standing debate on where on the time axis the transition between time perception and time estimation (i.e., the cognitive reconstruction of time) can be located. According to Fraisse (1984), time perception applies to intervals < 300 ms, whereas intervals > 1 s are subject to time estimation. While there is good empirical evidence for this notion, it might be possible to further pinpoint the threshold. In two experiments, an auditory temporal generalization (TG) task in the range of 400 ms was used to compare event-related potentials (ERPs) with findings from an analogous task using standard durations in the range of 200 ms. As an ERP correlate of actively processed durations around 400 ms, offset latency of a medial central/centroparietal contingent negative variation (CNV) was identified. Thus, durations of around 400 ms may be coded as the duration of mental processes and, hence, are cognitively reconstructed (time estimation). This contrasts with again replicated ERP correlates of TG in the 200-ms range, which involve amplitude modulations of stationary P300/P500 components and suggest an immediate evaluation of durations around 200 ms. It is concluded that the P300 span may denote the transition between time perception and time estimation. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
