TL;DR: In this article, a temporal bisection task was performed where participants were required to classify the duration of a stimulus as short or long, when gaze was directed at the observer, suggesting that effects of direct gaze are caused by attentional capture, not increased arousal.

TL;DR: By constructing Gaussian Naïve Bayes Classifiers, this work has re-analyzed data from an earlier event-related potential (ERP) study of an illusion in time perception known as auditory temporal assimilation and suggested Chernoff information, unlike accuracy or Kullback–Leibler (KL) distance, suggested brain activation associated with auditory temporal Assimilation at an early pre-decision stage.
Abstract: By constructing Gaussian Naive Bayes Classifiers, we have re-analyzed data from an earlier event-related potential (ERP) study of an illusion in time perception known as auditory temporal assimilation In auditory temporal assimilation, two neighboring physically unequal time intervals marked by three successive tone bursts are illusorily perceived as equal if the two time intervals satisfy a certain relationship The classifiers could discriminate whether or not the subject was engaged in the task, which was judgment of the subjective equality between the two intervals, at an accuracy of >79%, and from principal component scores of individual average ERP waveforms, we were able to predict their subjective judgments to each stimulus at an accuracy of >70% Chernoff information, unlike accuracy or Kullback–Leibler (KL) distance, suggested brain activation associated with auditory temporal assimilation at an early pre-decision stage This may provide us with a simple and useful neural decoding scheme in analyzing information processing of temporal patterns in the brain

TL;DR: In this article, patients with Parkinson's disease and progressive supranuclear palsy (PSP) over-reproduced shorter durations and under-produced longer durations at extremes of the time range studied, with a shallower slope of linear correlation between the presented and produced time.
Abstract: Although animal studies and studies on Parkinson's disease (PD) suggest that dopamine deficiency slows the pace of the internal clock, which is corrected by dopaminergic medication, timing deficits in parkinsonism remain to be characterized with diverse findings. Here we studied patients with PD and progressive supranuclear palsy (PSP), 3-4 h after drug intake, and normal age-matched subjects. We contrasted perceptual (temporal bisection, duration comparison) and motor timing tasks (time production/reproduction) in supra- and sub-second time domains, and automatic versus cognitive/short-term memory-related tasks. Subjects were allowed to count during supra-second production and reproduction tasks. In the time production task, linearly correlating the produced time with the instructed time showed that the "subjective sense" of 1 s is slightly longer in PD and shorter in PSP than in normals. This was superposed on a prominent trend of underestimation of longer (supra-second) durations, common to all groups, suggesting that the pace of the internal clock changed from fast to slow as time went by. In the time reproduction task, PD and, more prominently, PSP patients over-reproduced shorter durations and under-reproduced longer durations at extremes of the time range studied, with intermediate durations reproduced veridically, with a shallower slope of linear correlation between the presented and produced time. In the duration comparison task, PD patients overestimated the second presented duration relative to the first with shorter but not longer standard durations. In the bisection task, PD and PSP patients estimated the bisection point (BP50) between the two supra-second but not sub-second standards to be longer than normal subjects. Thus, perceptual timing tasks showed changes in opposite directions to motor timing tasks: underestimating shorter durations and overestimating longer durations. In PD, correlation of the mini-mental state examination score with supra-second BP50 and the slope of linear correlation in the reproduction task suggested involvement of short-term memory in these tasks. Dopamine deficiency didn't correlate significantly with timing performances, suggesting that the slowed clock hypothesis cannot explain the entire results. Timing performance in PD may be determined by complex interactions among time scales on the motor and sensory sides, and by their distortion in memory.

Journal ArticleDOI
TL;DR: It is concluded that the relationship between the physical duration of a stimulus and its perceptual duration is not yet understood.
Abstract: It has been suggested in the recent literature that all stimuli briefer than a critical duration have identical perceptual durations. Relevant simultaneity, reaction time, temporal order and duration discrimination data are discussed, and new data are presented. It is concluded that the relationship between the physical duration of a stimulus and its perceptual duration is not yet understood.
