TL;DR: A modification to the oft-repeated claim that more intense stimuli seem to last longer is urged, and the effect of intensity becomes more pronounced at longer durations, consistent with the idea that stimulus intensity affects the pacemaker component of an internal clock.
Abstract: This article explores the widely reported finding that the subjective duration of a stimulus is positively related to its magnitude. In Experiments 1 and 2 we show that, for both auditory and visual stimuli, the effect of stimulus magnitude on the perception of duration depends upon the background: Against a high intensity background, weak stimuli are judged to last longer. In Experiment 3 we show that the effect of intensity becomes more pronounced at longer durations, consistent with the idea that stimulus intensity affects the pacemaker component of an internal clock, and that it is the difference of a stimulus from the background, rather than its absolute magnitude, which influences the rate of the pacemaker. These results urge a modification to the oft-repeated claim that more intense stimuli seem to last longer, and provide an important constraint on any model of human timing.

TL;DR: It is confirmed that temporal intervals are represented as horizontally arranged in space, but also revealed that spatial modulation of time processing most likely occurs via cuing of spatial attention, and that spatial attention can influence the spatial coding of quantity in different dimensions.
Abstract: Previous studies have demonstrated the involvement of spatial codes in the representation of time and numbers. We took advantage of a well-known spatial modulation (prismatic adaptation) to test the hypothesis that the representation of time is spatially oriented from left to right, with smaller time intervals being represented to the left of larger time intervals. Healthy subjects performed a time-reproduction task and a time-bisection task, before and after leftward and rightward prismatic adaptation. Results showed that prismatic adaptation inducing a rightward orientation of spatial attention produced an overestimation of time intervals, whereas prismatic adaptation inducing a leftward shift of spatial attention produced an underestimation of time intervals. These findings not only confirm that temporal intervals are represented as horizontally arranged in space, but also reveal that spatial modulation of time processing most likely occurs via cuing of spatial attention, and that spatial attention can influence the spatial coding of quantity in different dimensions.

TL;DR: The autism group was less able to integrate auditory information present in temporal dips in background sound, supporting the complexity-specific perceptual account.
Abstract: The perceptual pattern in autism has been related to either a specific localized processing deficit or a pathway-independent, complexity-specific anomaly. We examined auditory perception in autism using an auditory disembedding task that required spectral and temporal integration. 23 children with high-functioning-autism and 23 matched controls participated. Participants were presented with two-syllable words embedded in various auditory backgrounds (pink noise, moving ripple, amplitude-modulated pink noise, amplitude-modulated moving ripple) to assess speech-in-noise-reception thresholds. The gain in signal perception of pink noise with temporal dips relative to pink noise without temporal dips was smaller in children with autism (p = 0.008). Thus, the autism group was less able to integrate auditory information present in temporal dips in background sound, supporting the complexity-specific perceptual account.

TL;DR: Recording from neurons in the dorsal medial superior temporal area of alert macaque monkeys reveals response properties that could account for perceptual observations relating to presaccadic suppression, postsaccadic enhancement and time compression.
Abstract: Humans use saccadic eye movements to make frequent gaze changes, yet the associated full-field image motion is not perceived. The theory of saccadic suppression has been proposed to account for this phenomenon, but it is not clear whether suppression originates from a retinal signal at saccade onset or from the brain before saccade onset. Perceptually, visual sensitivity is reduced before saccades and enhanced afterward. Over the same time period, the perception of time is compressed and even inverted. We explore the origins and neural basis of these effects by recording from neurons in the dorsal medial superior temporal area (MSTd) of alert macaque monkeys. Neuronal responses to flashed presentations of a textured pattern presented at random times relative to saccades exhibit a stereotypical pattern of modulation. Response amplitudes are strongly suppressed for flashes presented up to 90 ms before saccades. Immediately after the suppression, there is a period of 200-450 ms in which flashes generate enhanced response amplitudes. Our results show that (1) MSTd is not directly suppressed, rather suppression is inherited from earlier visual areas; (2) early suppression of the visual system must be of extra-retinal origin; (3) postsaccadic enhancement of neural activity occurs in MSTd; and (4) the enhanced responses have reduced latencies. As a whole, these observations reveal response properties that could account for perceptual observations relating to presaccadic suppression, postsaccadic enhancement and time compression.

TL;DR: In this article, a class of adaptive-oscillator processing units are proposed to track periodicities in rhythmic patterns (beats) and an entrainment model of human time perception is then developed.
Abstract: Many human behaviors reflect the attunement of our perceptual systems to rhythmic patterns of stimulation Examples include dancing to music, speech communication, and the performance of a symphony orchestra However, developing a computational model of rhythm perception has proven to be difficult for two main reasons First, rhythm is holistic, yet rhythmic patterns evolve over time Second, periodicities in rhythmic patterns typically exhibit variability in their timing Many previous approaches to rhythm perception have ignored these two problems by abstracting time to the level of musical notation, and thus failed to address the fundamental issue of the perception of time The approach taken in this thesis is that the development of a model of rhythm perception must first address the perception of the time intervals which comprise rhythmic patterns I propose a class of adaptive-oscillator processing units which track periodicities in rhythmic patterns (beats) Modest random variations in the timing of rhythmic patterns do not reduce the adaptive oscillator's ability to attain synchrony, and can even improve it An Entrainment Model of human time perception is then developed The model is evaluated by comparing its performance on a series of tempo-discrimination simulations to data from analogous human listening experiments, investigating several rhythmic factors that influence listeners' ability to detect differences in the tempo of isochronous auditory sequences Data obtained from the simulations agreed with the human data, providing support for the model As an additional evaluation, two tempo-discrimination experiments were conducted to test model predictions regarding the perception of time as phase The results of these two experiments also agreed with the model Compared with other psychological models of time perception, the adaptive-oscillator-based Entrainment Model is the only model to provide a unified explanation for these tempo data This thesis supports the adaptive-oscillator mechanism as a viable approach to modeling rhythm perception, addressing the holistic nature of rhythm, the problem of timing variability, and the perception of time Furthermore, this thesis demonstrates how direct coupling of a computational system with the temporal structure of its environment is a potentially useful method for learning to interact with that environment
