TL;DR: The role of novelty and significance in the time-delaying effect of distracters and the role of medial prefrontal cortex catecholamines by local infusion of norepinephrine-dopamine reuptake inhibitor (NDRI) nomifensine in a peak-interval (PI) procedure in rats is investigated to help elucidate the behavioral and physiological mechanisms underlying interval timing and attention to time.
Abstract: The behavioral and neural mechanisms by which distracters delay interval timing behavior are currently unclear. Distracters delay timing in a considerable dynamic range: Some distracters have no effect on timing ("run"), whereas others seem to "stop" timing; some distracters restart ("reset") the entire timing mechanisms at their offset, whereas others seem to capture attentional resources long after their termination ("over-reset"). While the run-reset range of delays is accounted for by the Time-Sharing Hypothesis (Buhusi, 2003, 2012), the behavioral and neural mechanisms of "over-resetting" are currently uncertain. We investigated the role of novelty (novel/familiar) and significance (consequential/inconsequential) in the time-delaying effect of distracters and the role of medial prefrontal cortex (mPFC) catecholamines by local infusion of norepinephrine-dopamine reuptake inhibitor (NDRI) nomifensine in a peak-interval (PI) procedure in rats. Results indicate differences in time delay between groups, suggesting a role for both novelty and significance: inconsequential, familiar distracters "stopped" timing, novel distracters "reset" timing, whereas appetitively conditioned distracters "over-reset" timing. mPFC infusion of nomifensine modulated attentional capture by appetitive distracters in a "U"-shaped fashion, reduced the delay after novel distracters, but had no effects after inconsequential, familiar distracters. These results were not due to nomifensine affecting either timing accuracy, precision, or peak response rate. Results may help elucidate the behavioral and physiological mechanisms underlying interval timing and attention to time and may contribute to developing new treatment strategies for disorders of attention.

TL;DR: In this article, a quasi-experimental within-subjects design was devised that manipulated emotion on two levels (positive and neutral) as well as cognitive load on two level (high and low) to investigate the effect on time perception.
Abstract: The literature predicts a paradoxical effect on time perception under the influence of positive emotion and high cognitive load in the retrospective paradigm. High cognitive load is expected to increase time perception, whereas positive emotion is expected to decrease time perception. A quasi-experimental within-subjects design was devised that manipulated emotion on two levels (positive and neutral) as well as cognitive load on two levels (high and low) to investigate the effect on time perception. The findings of the study prove disappointing with no main effects witnessed along any of the four experimental conditions. Participants overestimated all the durations, but under the high cognitive load, positive emotion condition, the mean time perception scores where the closest to the chronological time.
