TL;DR: This work examines subjects catching a virtual ball and shows that subjects in a natural task are quantitatively aware of how sensory and motor variability depend on time and act so as to minimize overall task variability.
Abstract: Most behavioral tasks have time constraints for successful completion, such as catching a ball in flight. Many of these tasks require trading off the time allocated to perception and action, especially when only one of the two is possible at any time. In general, the longer we perceive, the smaller the uncertainty in perceptual estimates. However, a longer perception phase leaves less time for action, which results in less precise movements. Here we examine subjects catching a virtual ball. Critically, as soon as subjects began to move, the ball became invisible. We study how subjects trade-off sensory and movement uncertainty by deciding when to initiate their actions. We formulate this task in a probabilistic framework and show that subjects' decisions when to start moving are statistically near optimal given their individual sensory and motor uncertainties. Moreover, we accurately predict individual subject's task performance. Thus we show that subjects in a natural task are quantitatively aware of how sensory and motor variability depend on time and act so as to minimize overall task variability.

TL;DR: A review of studies on the effects of emotion on time judgments can be found in this article. But the results of these studies are limited to affective disorders, and they do not consider the effect of emotions on the basic mechanisms involved in time perception.
Abstract: The past few decades have seen an explosion in studies exploring the effects of emotion on time judgments. The aim of this review is to describe the results of these studies and to look at how they try to explain the time distortions produced by emotion. We begin by examining the findings on time judgments in affective disorders, which allow us to make a clear distinction between the feelings of time distortion that originate from introspection onto subjective personal experience, and the effects of emotion on the basic mechanisms involved in time perception. We then report the results of behavioral studies that have tested the effects of emotions on time perceptions and the temporal processing of different emotional stimuli (e.g. facial expressions, affective pictures or sounds). Finally, we describe our own studies of the embodiment of timing. Overall, the different results on time and emotion suggest that temporal distortions are an indicator of how our brain and body adapt to the dynamic structure of our environment.

TL;DR: Time estimation together with the simultaneously recorded electroencephalogram is examined to examine whether evidence of an interference pattern between sensory pulse rates and time judgments can be found in the EEG.
Abstract: It has been proposed that temporal perception and performance depend on a biological source of temporal information. A model for a temporal oscillator put forward by Treisman, Faulkner, Naish, and ...

TL;DR: The 5–year–olds judged visual stimuli as more variable than auditory ones, indicating that their temporal sensitivity was lower in the visual than in the auditory modality, and a theoretical model suggested that this modality effect was due to differences in the pacemaker speed of the internal clock.
Abstract: This experiment investigated the effect of modality on temporal discrimination in children aged 5 and 8 years and adults using a bisection task with visual and auditory stimuli ranging from 200 to 800 ms. In the first session, participants were required to compare stimulus durations with standard durations presented in the same modality (within-modality session), and in the second session in different modalities (cross-modal session). Psychophysical functions were orderly in all age groups, with the proportion of long responses (judgement that a duration was more similar to the long than to the short standard) increasing with the stimulus duration, although functions were flatter in the 5-year-olds than in the 8-year-olds and adults. Auditory stimuli were judged to be longer than visual stimuli in all age groups. The statistical results and a theoretical model suggested that this modality effect was due to differences in the pacemaker speed of the internal clock. The 5-year-olds also judged visual stimuli as more variable than auditory ones, indicating that their temporal sensitivity was lower in the visual than in the auditory modality.

TL;DR: Visual–spatial memory was found to be a significant predictor of visual and auditory duration Discrimination at longer intervals in the ADHD sample, whereas auditory verbal working memory predicted auditory discrimination at longer interval in the control sample.
Abstract: Time perception performance was systematically investigated in adolescents with and without attention-deficit/hyperactivity disorder (ADHD). Specifically, the effects of manipulating modality (auditory and visual) and length of duration (200 and 1000 ms) were examined. Forty-six adolescents with ADHD and 44 controls were administered four duration discrimination tasks and two control tasks, and a set of standardized measures. Participants with ADHD had higher thresholds than controls on all of the duration discrimination tasks, with the largest effect size obtained on the visual 1000 ms duration discrimination task. No group differences were observed on the control tasks. Visual-spatial memory was found to be a significant predictor of visual and auditory duration discrimination at longer intervals (1000 ms) in the ADHD sample, whereas auditory verbal working memory predicted auditory discrimination at longer intervals (1000 ms) in the control sample. These group differences suggest impairments in basic timing mechanisms in ADHD.
