Is subjective duration a signature of coding efficiency
TLDR
In this article, the authors suggest that the experience of duration is a signature of the amount of energy expended in representing a stimulus, i.e., the coding efficiency of a stimulus.Abstract:
Perceived duration is conventionally assumed to correspond with objective duration, but a growing literature suggests a more complex picture. For example, repeated stimuli appear briefer in duration than a novel stimulus of equal physical duration. We suggest that such duration illusions appear to parallel the neural phenomenon of repetition suppression, and we marshal evidence for a new hypothesis: the experience of duration is a signature of the amount of energy expended in representing a stimulus, i.e. the coding efficiency. This novel hypothesis offers a unified explanation for almost a dozen illusions in the literature in which subjective duration is modulated by properties of the stimulus such as size, brightness, motion and rate of flicker.read more

The inner sense of time: how the brain creates a representation of duration
TL;DR: Human and animal studies point to 'climbing neural activation' as a potential neural mechanism for the representation of duration, and, in humans, climbing neural activity in the insular cortex, which is associated with feeling states of the body and emotions, may be related to the cumulative representation of time.

Temporal cognition: Connecting subjective time to perception, attention, and memory.
William Matthews,Warren H. Meck +1 more
TL;DR: It is shown that many of these connections instantiate a "processing principle," according to which perceived time is positively related to perceptual vividity and the ease of extracting information from the stimulus, which generates testable predictions and provides a starting-point for integrated theoretical frameworks.

Bayesian optimization of time perception.
TL;DR: It is shown that the essential components of a Bayesian framework are closely related to the clock, memory, and decision stages used by these models, and that such an integrated framework offers a new perspective on distortions in timing and time perception that are otherwise difficult to explain.
