Abstract: A temporal reproduction task is composed of two temporal estimation phases: encoding of the interval to be reproduced, followed by its reproduction. The effect of short-term memory processing on each of these phases was tested in two experiments. In Exp. 1, a memory set was presented, followed by two successive tones bounding the target interval to be reproduced. During the reproduction of the target interval, a probe was presented, and the subject ended the reproduction by pressing one of two keys, depending on the presence or absence of the probe in the memory set. In Exp. 2, probe recognition was required during the encoding of the interval to be reproduced. Whereas in Exp. 1 reproductions lengthened as a function of memory-set size, in Exp. 2 temporal reproductions decreased with set size. These results support attentional models of time estimation and suggest that short-term memory processing interrupts concurrent accumulation of temporal information.

Neuroanatomical and neurochemical substrates of timing.
TL;DR: Neural firing rates in both striatal and interconnected frontal areas vary as a function of duration, suggesting a neurophysiological mechanism for the representation of time in the brain, with the excitatory–inhibitory balance of interactions among distinct subtypes of striatal neuron serving to fine-tune temporal accuracy and precision.

How cognitive load affects duration judgments: A meta-analytic review
TL;DR: A meta-analysis of 117 experiments evaluated the effects of cognitive load on duration judgments and found models emphasizing attentional resources, especially executive control, support and alternative theories do not fit with the meta-analytic findings.

TL;DR: This study is the first to systematically assess the impact of psilocybin on timing performance on standardized measures of temporal processing, and indicates that the serotonin system is selectively involved in duration processing of intervals longer than 2 to 3 seconds and in the voluntary control of the speed of movement.

The right dorsolateral prefrontal cortex is essential in time reproduction: an investigation with repetitive transcranial magnetic stimulation
TL;DR: The suggest that the selectivity of the rTMS effect for the Reproduction Phase indicates that the right DLPFC plays a particular role in memory processes, consistent with previous studies showing that theright DLP FC is important in estimating time intervals in the seconds-range.

Attentional processes in time perception: effects of mental workload and event structure.
TL;DR: The results point to the central role of attention in temporal experience, as increases in workload and the degradation of structure led to inaccurate reproductions.

High-Speed Scanning in Human Memory
TL;DR: When subjects judge whether a test symbol is contained in a short memorized sequence of symbols, their mean reaction-time increases linearly with the length of the sequence, implying the existence of an internal serial-comparison process.

Scalar timing in memory.
TL;DR: The generalized account proposed here will develop the conclusion that scalar sources dominate in some time ranges, while other sources may dominate in others, and are applied to two additional timing tasks with different characteristics.

The perception of time
TL;DR: The present paper organizes and evaluates selected portions of the time perception literature as mentioned in this paper, with a focus on data and theory concerned primarily with judgments of brief temporal intervals and the role of nontemporal information.

Cognitive processing and time perception
TL;DR: This article found that the perceived difference between filled and blank visual fields increases when the subject is required to memorize the presented letters, but is the same whether the three letters form a word or not.
